INTRODUCTION  
Safety is the most important consideration when  
installing your fire. If not properly installed and  
operated a house fire may result. Installation must  
comply with the Building Regulations and conform  
to all relevant fire safety standards.  
SAFETY  
A fireguard conforming to BS 8423: 2002 should  
be used in the presence of children and old/or  
infirm people. If the appliance is used with the fire  
door open, a spark guard conforming to BS 3248  
should be fitted.  
Aarrow Fires produce a variety of appliances  
ranging from units, which are traditional in style to  
stoves which are modern in appearance, all  
bristling with "High Tech" features.  
Do not use aerosol sprays or any other flame  
near the appliance under fire.  
Do not fit an extractor fan in the same room as  
the appliance.  
Fire cement is caustic, hand and eye protection  
should always be worn, prolonged contact with  
the skin should be avoided.  
Aarrow Fires Ltd will not be responsible for any  
consequential or incidental loss or injury  
however caused.  
Model types include simple room heaters,  
convectors, integral boiler models and inset units.  
Your Aarrow Fire is constructed from either single  
or twin wall steel strengthened where necessary.  
Cast iron is used where appropriate for decorative  
features.  
All fire doors are fitted with special high  
temperature ceramic glass panels through which  
the fire can be viewed.  
Before continuing any further with the installation  
of this appliance please read the following guide to  
manual handling.  
Multifuel stoves are fitted with a cast iron grate to  
give full multifuel facility and positive de-ashing.  
• Always obtain assistance when lifting the  
appliance.  
• When lifting always keep your back straight.  
Bend your legs not your back.  
• Avoid twisting at the waist. It is better to  
reposition your feet.  
All models except integral boiler models are lined  
with firebricks or heat reflective panels which  
ensure complete combustion and provide a good  
heat store to even out fluctuations in burning.  
• Avoid upper body/top heavy bending. Do not  
lean forwards or sideways when  
handling the fire.  
• Always grip with the palms of your hands.  
Do not use fingertips for support.  
• Always keep the stove as close to the body as  
possible. This will minimise the cantilever  
action.  
An internal throat plate produces turbulence to  
encourage secondary combustion and directs the  
flue gas around the whole upper firebox before  
allowing it to escape up the chimney.  
On multifuel appliances the primary air for burning  
enters the ash pit chamber beneath the grate,  
controlled by the air inlet mechanism.  
• Use gloves to provide additional grip.  
Aarrow Fires are also fitted with an "air wash" so  
called because it provides a curtain of high speed  
preheated air behind the glass to help keep it clean  
and to provide secondary air/over draught.  
THE PRINCIPLE OF THE FIRE  
Your Aarrow Fire is built to the highest standard of  
craftsmanship using the best materials and the most  
modern equipment available. It is a highly efficient  
and sophisticated piece of machinery and when  
properly installed and operated it should provide a  
lifetime of heating satisfaction.  
The provision of two inlets on all multifuel stoves  
gives a wide range of primary air/secondary air,  
under draught/over draught combinations. The  
optimum settings will only be established by  
experience in firing the appliance, and will depend  
on type of fuel, the position of the appliance in the  
house, condition of chimney etc.

OPERATING INSTRUCTIONS  
MULTIFUEL GRATE  
AARROW AIR WASH SYSTEM  
The air wash has an internal sliding plate with slots,  
housed in a cover plate, and is located above the  
fire door. Sliding the control shaft to the right as far  
as it will go achieves the fully open position.  
Sliding it to the left will shut off the air inlet slots.  
The operating tool should be used to tap the control  
shaft to the desired setting.  
The Aarrow Multifuel grate comprises of a series of  
reciprocating cast iron bars seated on a pivoted  
"comb". These should come fitted in your stove, if  
not please refer to page 16 for fitting and operation  
and also operating instructions on fuels for correct  
settings of the grate.  
AIR INLET CONTROLS  
Stratford multifuel stoves have three air inlets:  
•The air wash system (so called because its  
pre-heated high speed air washes across the inner  
face of the door glass, keeping it clear), which  
provides over draught, and  
Fig. 1 Fully Closed  
Fig. 2 Fully Open  
•The primary air inlet providing under draught to  
the base of the fire chamber through the gap  
between the body and the ash pit door.  
•Most importantly on the Stratford Boiler stoves is  
the thermostatic control system.  
Note: Opening or part opening of the ash door is  
controlled by the "interlock" device located in the  
front of the unit (refer to INTERLOCK section on  
page 9). Even when all the slots are completely shut  
a "bleed" of secondary air will be maintained  
ensuring that inflammable gases are burnt off.  
Please note partial opening of the ash door will  
over-ride and negate the thermostatic control.  
DISASSEMBLE AIR WASH  
The Stratford air wash may be disassembled for  
cleaning or adjustment. To achieve this, the  
following procedure should be followed:  
THERMOSTATIC CONTROL  
Stratford Tf Integral Boilers have  
a
thermostatically controlled side air inlet, beneath an  
access plate.  
This should only be carried out when the fire is cold  
and unlit.  
The damper plate at the rear/side of the appliance  
regulates the amount of under draught entering,  
depending on the setting of the thermostat control  
knob (located at the bottom front on the left hand  
side of the unit) and the temperature of the water  
transmitted through the sensor phial in the water  
•Support Air wash cover with one hand  
•Move cover up by smartly tapping the bottom with  
a hammer. (Fig. 3)  
•Remove assembly from appliance.  
•Clean and/or adjust.  
jacket.  
•Refit using reverse procedure.  
Stratford Tf and Ti with the ash door fully shut,  
the settings range from 0 (fully anti-clockwise) a  
shut-off setting at which the damper will shut off  
the underdraught completely, causing the fire to die  
down and in time go out, to 8 (fully clockwise) the  
highest setting at which the appliance will burn  
fiercely and produce very high outputs.  
For more information on the Ti inset model please  
see page 20.  
Note: The area around the thermostat, both inside  
at the back of the firebox and externally, must be  
cleared of ash and other debris regularly.  
(See page 13). For setting instructions refer to  
"Checking Thermostat" on page 19 .

Stratford Tf & Ti Multifuel Boiler Stoves  
OPERATING INSTRUCTIONS  
INTERLOCK SYSTEM  
DOOR TRIM  
Stratford Tf and Ti Multifuel Boiler Stoves are  
fitted with an "interlock" system. A situation where  
the fire door is closed and the ash door is open may  
lead to serious overfiring which could damage the  
appliance. Correct use of the doors and interlock  
system will ensure that this does not happen.  
Stratford fire doors are fitted with a brushed steel  
finish trim as standard. This clips on to the small  
lugs at the top and bottom of the aperture in the cast  
iron fire door, as a "spring fit". When fitted, the trim  
locks the glass retaining clips in position. (Fig 5)  
The fire door should be removed so that the above  
operations can be carried out on a workbench or  
similar. Remove the door by GENTLY tapping the  
door upwards; this will lift off of its hinges.  
Operation is as follows:  
A pivoted lug prevents closure of the fire door,  
unless the ash door has been shut first. When the  
fire door is shut the ash door knob can be turned  
anti-clockwise by up to 95 degrees creating a  
variable gap between the top of the ash door and the  
body, through which primary combustion air can  
enter the appliance.  
Note: In order to turn the ash door knob  
sufficiently for the catch to release and permit the  
ash door to be opened fully THE FIRE DOOR  
MUST BE OPENED FIRST.  
MULTI PURPOSE OPERATING  
TOOL  
Your Aarrow fire comes with a multi-purpose  
operating tool which is used to open the ashpit  
door, riddling, setting the multifuel grate position  
and for emptying the ash pan. (see fig.4)  
Trim Fit Fig 5  
FIRE DOOR GLASS  
If necessary the glass can be removed as follows  
Step 1 Remove the brushed steel finish trim by  
pressing on the curved edge at the top until the trim  
can be disengaged from the lugs.  
Step 2 Slide the two glass retainer clips on one side  
only, inwards, towards the centre of the door as far  
as they will go.  
Fig. 4  
Step 3 Pull this side of the glass away from the door  
casting, easing the tags on the glass retaining clips  
past the edge of the aperture in the door casting.  
RIDDLING  
Use the operating tool for setting the grate in the  
coal burning position or the wood burning position.  
This means that effective de-ashing takes place,  
and also allows the grate to be set in the coal  
burning or wood burning position, as indicated on  
the right hand side of the appliance.

OPERATING INSTRUCTIONS  
Step 4 Remove the glass completely. Store glass-  
retaining clips and white gasket (if sound) safely  
for re-use.  
•Gently tap the two hinge pins in a direction to  
compensate for the misalignment.(fig 7)  
Step 5 Follow this procedure in reverse to fit  
replacement door glass or gasket.

•Refit the door and check to ensure it now sits  
square to the body; if not repeat above steps.  
Raising the door as follows:  
•When the appliance is cold, open the fire door so  
that it is at a right angle to the front.  
•Lift the fire door up off the hinges.  
Fig. 6  
•Drop one washer on the top and bottom hinge pin.  
•Refit the door and check to ensure door is free of  
the interlock. If not remove and repeat fitting  
second washer.  
DOOR ADJUSTMENT  
The catch can be adjusted by sharply tapping the  
catch on the inside of the door.  
FUEL RETAINER BARS  
Fuel retainer bars are supplied with the fires.  
For wood burning, 1 fuel retainer bar is used,  
affording a better view of the fire. Slide and lift the  
bar until it is clear of the guides at each side, and  
remove through the fire door opening.  
The bars are symmetrical and of even lengths  
making incorrect fitting impossible.  
Note: This operation should only be carried out  
when the appliance is unlit and cold.  
Once the appliance has been under fire for a period  
of time the fire door may appear to have moved out  
of alignment with relation to the door aperture or  
catch on the door interlock mechanism. This is  
quite normal and due to the settling of the casing.  
The fire door can be re-aligned by the user as  
follows:  
•When the appliance is cold, open the fire door so  
that it is at a right angle to the front face of the fire.  
•Lift the fire door up off the hinges.

OPERATING INSTRUCTIONS  
Approval does not cover the use of other fuels  
either alone or mixed with the suitable fuels listed  
above, nor does it cover instructions for the use of  
other fuels.For latest details please refer to Hetas  
FUEL TYPES  
Wood- Any type of wood is suitable provided it is  
well seasoned and has a moisture content below  
20%. This usually implies that the timber has been  
suitably stored to allow moisture to evaporate for at  
least nine months in the case of soft woods, and at  
least eighteen months in the case of hard wood. We  
recommend that for general burning, wood should  
be split into logs of no more than 130mm (5")  
diameter.  
Do not use Homefire (six sided) and smaller sizes  
than Stovesse, e.g. Beans, Peas,Grains.  
Do not use petroleum based solid products such  
as Calco or Petrocoke.  
To do so will invalidate the appliance guarantee  
Larger logs can be used for overnight burning.  
LIGHTING THE FIRE  
WARNING wet wood must not be used as this will  
greatly contribute to the creation of tar and creosote  
which may, in extreme cases, run down the  
chimney in liquid form. This will seriously damage  
both the chimney and the appliance, and increase  
the risk of chimney fire.  
Prior to lighting the fire for the first time check  
with the installer that:  
•Installation and all building work is complete.  
•The chimney is sound and has been swept and is  
free from obstruction.  
•Adequate provision for combustion air has  
been made, i.e. a permanent vent of at least  
550mm² per kW of rated output above 5 kW,  
is fitted in the room in which the appliance  
is installed.  
Note: If you have sticky tar inside the appliance or  
chimney your wood is 'Green' or too wet.  
Recommended Reading:  
"Wood as Fuel" available from the Forestry  
Commission.  
•That Building Regulations and any local  
by-laws have been followed during installation  
(see installation instructions).  
Peat- Can be used in turf or briquette form, but  
again the moisture content must be low.  
•Throat plate is in place.  
•Ensure that the system is full of water and  
vented, and precautions have been taken to  
prevent corrosion  
Paper- paper will burn successfully. Burn dry  
paper only or chimney damage will occur.  
(see installation Instructions).  
NEVER BURN PLASTICS OR WASTE IN  
YOUR STOVE.  
•That the chimney draw has been checked and is  
within specification. With the chimney warm the  
draught should be between 1 - 2mm water gauge  
(0.1 - 0.2mbar).  
Coal - Household coal produces a large amount of  
ash and smoke. If used the appliance and chimney  
will require frequent cleaning. Therefore soft house  
coal is not recommended.  
WARNING: An over drawing chimney can cause  
over-firing resulting in damage to the appliance.  
Recommended fuels are as follows:  
WARNING: Do not light the fire if it is suspected  
that any part of the water system is frozen.  
The Hetas Ltd, "Three Tick" appliance approval  
only covers the use of the following fuels in this  
appliance;Phurnacite, Phurnacite Plus, Centurion,  
Maxibrite, Extracite, Pureheat, Blazebrite,  
Taybrite, Sunbrite (Doubles/Singles), Anthracite  
(Large Nuts), and Welsh Dry Steam Coal  
(Large/Small Nuts).

OPERATING INSTRUCTIONS  
ENSURE THAT YOU HAVE READ  
UNDERSTOOD THESE INSTRUCTIONS  
BEFORE LIGHTING THE FIRE.  
&
OVERNIGHT BURNING  
The appliance will burn overnight provided:  
•Sufficient fuel is placed in the firebox.  
•The controls are set correctly.  
•Excess draught is not present in the chimney.  
•Close the door.  
•If the fire goes out with unburnt fuel left in the  
firebox increase the thermostat setting, and vice  
versa.  
ALWAYS WEAR SUITABLE PROTECTIVE  
FIRE GLOVES WHEN REFUELLING YOUR  
STOVE.  
SOLID FUEL BURNING  
•Set the grate to ‘coal’ position.  
•Ensure that the ash pan is in position and the fire  
doors are closed.  
•Set the air wash to one quarter open position.  
•Set the thermostat control knob to position 8  
•Light in the normal manner with paper and  
kindling, or use a fire lighter.  
•If using a gas poker be sure to remove it  
immediately the fire is alight.  
•When the fire is well alight regulate the burning  
rate by adjusting the setting on the thermostat  
control knob  
In the morning  
Open the air control fully until embers begin to  
glow brightly and place pieces of fuel on the fire  
until it is well established.  
WARNING: When wood is burnt slowly in a  
closed appliance it produces moisture and tar,  
which will create condensation and deposits in the  
chimney. This effect can be minimised by burning  
hard for a short period, about 20 minutes, twice a day.  
It is usually convenient to do this morning and night.  
•The air wash can be opened sufficiently to keep  
the door glass clean  
Note: To avoid chimney problems your fire should  
not be burnt slowly for longer than 12 hours  
without a period of fast burning.  
BURNING WOOD  
•Set air wash to fully open position.  
•Proceed as for solid fuel but note the fire will burn  
up and become established more quickly.  
WARNING: Properly installed, with a suitable  
flue and chimney and operated and maintained  
this appliance will not emit fumes into the  
dwelling. Occasional fumes from the de-ashing  
and re-fuelling may occur. However, persistent  
fume emission is potentially dangerous and must  
be investigated by a Hetas registered installer.  
MIXED FUELS  
•As per coal but allow additional secondary air.  
ANTHRACITE  
Anthracite is more difficult to keep in for long  
periods, consequently more care in setting the  
controls and some familiarisation is necessary  
when burning anthracite.  
Use the smallest size fuel (Stovesse or Small Nuts).  
Proceed as for manufactured smokeless fuel. Leave  
the air inlet control open about a quarter or less.  
Stop using the appliance if you smell fumes or  
see smoke escaping.  
If fume emission does persist, the following  
immediate actions should be taken.  
•Open doors and windows to ventilate room.  
•Let the fire die or extinguish and safely  
dispose of fuel from the appliance.  
•Check for flue or chimney blockage, and  
clean if required.  
Note: The high temperature paint acquires  
durability by being "cured" during the initial  
firings of the appliance will give off fumes which  
are non-toxic, but which certain persons may find  
have an unpleasant or irritant effect. Ensure that  
the area is well ventilated during this time.  
Seek expert advice from your HETAS registered  
installer. Do not attempt to re-light the fire until the  
cause of the fume emission has been identified and  
corrected.

OPERATING INSTRUCTIONS  
brigade. A chimney fire may cause structural  
damage of the chimney. Do not use the appliance  
until the chimney and connector have been  
inspected and any damaged parts repaired or  
replaced. This should be done by a competent person  
such as a HETAS registered engineer.  
ASH REMOVAL  
The ash pan should be emptied at least twice a day  
or when the level of ash reaches the top of the ash  
pan. On no account should the ash be allowed to  
build up to touch the grate as this will greatly  
shorten its life.  
DE - ASHING  
CLEANING  
It is necessary to maintain an ash layer on the upper  
surface of the grate bars, in order to protect them so  
de-ashing should cease as soon as the first red  
embers drop into the ash pan. Further de-ashing  
will cause heat build-up under the grate, which will  
considerably shorten its life. This operation should  
be carried out with the doors closed to prevent dust  
escaping into the room.  
IMPORTANT  
Under some circumstances soot can quickly build  
up on the throat plate and adjacent areas. The throat  
plate should be removed and checked monthly, and  
any debris stripped off. Similarly, clean the upper  
surface of the firebox.  
Refer to page 16 for instructions on throat plate  
removal/inspection.  
•Move up and down vigorously the riddling lever  
(ash will fall into the ash pan beneath the grate).  
•When de-ashing is complete re-set grate to  
previous position.  
• Empty ash pan.  
Note: Do not force the riddling lever.  
IF ASH BUILDS UP AROUND THE  
THERMOSTAT OPENING.  
1.Make sure the fire is unlit and cold.  
2.Remove the access plate. (See page 19)  
Carefully clean the cold ash from the thermostat  
using a vacuum cleaner. Re-fit the access cover.  
Also the area to the left hand side of the firebox  
should be swept clean.  
TO EMPTY THE ASH PAN  
Open the fire door; open the ash door. Fit the fork  
end of the operating tool into the ash pan and  
remove from the ash pit chamber.  
WARNING PERFORM THESE OPERATIONS  
WHEN THE STOVE IS UNLIT AND COLD.  
WARNING: The ash can be very hot. Empty only  
to a metal container. Even if the ash appears cold,  
red-hot pieces of ash may be concealed and could  
easily start a fire or cause an injury. Replace the ash  
pan and close ash door. Close the fire down.  
ACCESSORIES  
STANDS  
Elegant stands are available for the Stratford  
free-standing fires. (Stands are not available for the  
inset models). These increase the height of the  
appliance and rear flue outlet by approximately:  
CLINKER  
The formation of clinker suggests that the unit is  
being over-fired. Any clinker forming on the grate  
should be removed when cold.  
Tf 30 by 125mm  
Tf 50 by 130mm  
Tf 70 by 135mm  
Tf 90 by 140mm  
OVER-FIRING  
Do not over fire your appliance. Using flammable  
liquids or too much wood or firing the fire at  
maximum for prolonged periods may result in  
over-firing. If the chimney connector or casing  
glows red it is being over-fired. If this occurs  
immediately close all air inlets to the appliance to  
reduce the air supply to the fire. Should a chimney  
fire occur immediately close the appliance down.  
Get everyone out of the house and call the fire  
TRACERIES  
For added decorative effect, beautiful door traceries  
are available for the complete Stratford fires range.  
PAINT  
Matching aerosol paint to tone in any connecting  
flues, pipes or surrounding metalwork.

SERVICING  
DOOR GLASS  
MAINTENANCE  
The door glass should remain clear during normal  
daytime burning. However under certain conditions-  
such as burning at a low rate with damp wood, or  
overnight burning, the glass may become somewhat  
blackened. To remedy this, operate the appliance at a fast  
rate. Alternatively when the stove is cold open the door  
and clean the inside face of the glass with a damp cloth  
or with glass cleaner (available from fire stockists). A  
piece of cloth moistened with vinegar and dipped in  
wood ash - not coal ash - will provide a good soft  
scourer to remove the soot without scratching the glass.  
It is important that your fire is regularly serviced in  
accordance with these instructions. This should be  
carried out at least annually by a qualified person  
and should consist of the following:  
When the appliance is cold and unlit ensure to  
remove the firebrick liners and throat plate. Inspect  
all gasketing on doors, glass etc., and re-order any  
items that may need replacing, from your Aarrow  
dealer. With a wire brush clean inside the appliance  
paying particular attention to the small inlet holes  
of the air wash on the inside, above the fire door  
and to the door. With Ti40 models ensure to sweep  
up around the damper flap regularly to avoid ash  
build up.  
OUTER FINISH  
The outside finish of the appliance is a durable high  
temperature paint. It is best cleaned by brushing  
down with a clean shoe brush. Do not allow  
moisture to remain on the appliance whilst cold or  
surface rust may form.  
Sweep the chimney and confirm that it is sound.  
Examine all joints in the flue pipe etc., and re-seal  
if necessary. Reassemble and leave with the air  
inlet and air wash control about half way open. This  
will allow a free flow of air through the appliance  
thus preventing moisture and condensation from  
building up inside the fire and chimney.  
The high temperature paint should not require  
attention for some time, depending on use. The  
hotter the fire burns the sooner repainting will be  
necessary. Aerosol tins of paint are available for  
complete refurbishing. Before repainting make sure  
that the fire is out and is cold.  
CHIMNEY SWEEPING  
•Remove the door glass.  
Sweeping should be carried out with an appropriate  
sized bristle brush and rods to suit chimney size and  
type.As with all appliances regular sweeping of the flue  
is essential to avoid the danger of blockage and the  
escape of poisonous fumes. Access for cleaning should  
also be incorporated in the chimney (e.g. soot door or  
access through register plate).  
•Lightly wire brush, or rub with wire wool, the  
body of the appliance to remove any loose paint  
powder.  
•Mask or remove items such as brass work.  
•Any adjacent brickwork, mantelpiece, hearth,  
etc., should be carefully masked for quite a  
distance around the appliance. (this precaution is  
to prevent discolouration of the surrounding brick  
work, wallpaper etc).  
Any existing chimney should be swept prior to  
installation of the appliance, and swept again a  
second time within one month of regular use after  
installation to establish frequency of sweeping  
required. This should be done by a competent  
person such as a NACS chimney engineers who  
will provide a Certificate of Chimney Sweeping.  
Re-spray in a well-ventilated area - avoid breathing  
the vapour. Refer to safety instructions on paint  
cans.  
•When the paint is dry refit door glass and any  
other parts previously removed.  
•Leave the appliance for eight hours before  
re-lighting.  
•Burn slowly for the first four hours, then build up  
heat gradually to cure the paint.  
Note: Use only genuine Aarrow touch-up spray as  
some paints interact. This could ruin the finish  
and invalidate the guarantee.  
Sweep the whole flue way, including the outlet, at  
least twice per burning season. It is important that  
the flue ways, flue pipe and chimney be cleaned  
prior to lighting the fire after a prolonged  
shut-down period.

INSTALLATION  
HEARTH  
GENERAL PRECAUTIONS  
The fire should be installed to stand on a  
constructional hearth of non-combustible materials  
not less than 125mm (5'') thick conforming to  
Building Regulations. Dimensions of the hearth  
should project at least 300mm (12'') forward of the  
front of the appliance and 150mm (6'') at the sides.  
The surface of the hearth should be free of  
combustible materials. In most buildings with solid  
concrete floors the requirement will be met by the  
floor itself, but mark the perimeter of the hearth to  
ensure floor coverings are kept well away or use  
different levels to mark the hearth perimeter.  
Note - All installations must conform to the  
appropriate building regulations.  
The Building Regulations for England and Wales  
2000 ref Approved Document J 2002 edition  
(issued by the DTLR).  
The Building Standards (Scotland) (Consolidation)  
Regulations.  
Detailed recommendations for installation of  
appliances, chimneys and flues are outlined in the  
current issue of the following British Standards:-  
BS6461, BS8303 and BS4543.  
COMBUSTIBLE MATERIALS  
A gap of at least 450mm (18'') should be allowed  
between the appliance and any combustible  
materials including furnishings. Adjacent walls  
should be of suitable non-combustible  
construction, preferably brickwork. In large  
fireplaces take care that any supporting beam is  
Any Manufacturer's Instructions must not be  
taken as overriding statutory requirements.  
During installation ensure that adequate  
precautions are taken to avoid unnecessary risk to  
yourself or any householder. In particular the  
danger from the caustic nature of the fire cement  
should be avoided by using these accepted  
methods:  
protected by  
a
13mm (0.5'') sheet of  
Masterboard/Supalux spaced 13mm (0.5'') off the  
surface with strips of non-combustible material  
- not wood.  
Make sure that there is a gap between an  
uninsulated flue system and any combustible  
material. This gap must be at least 3 x the outside  
diameter of the flue pipe, or 1.5 x the flue diameter  
to non combustible surfaces. See the illustration on  
page 22.  
• Wear gloves when handling fire cement.  
• Wear goggles when chiselling or looking up  
chimneys.  
Make sure that Building Regulations are adhered to  
during installation along with any local by-laws. In  
the case of heating systems make sure that the pipe  
work is correctly bonded to ensure electrical  
earthing.  
AIR FOR COMBUSTION  
There must always be a permanent means of  
providing air for combustion into the room in  
which the fire is installed. A permanent vent with a  
HANDLING  
2
total free area of at least 550mm for every kW  
By the time you read this you will appreciate the  
weight of the appliance. The Safety and handling  
guidelines as set out on page 5 of this manual  
should be followed.  
To make movement easier internal fittings, fuel  
retainers, grates, firebox liners, flue outlets, hot  
plate, throat plate, etc., can be removed.  
rated output above 5kw should be connected  
directly to the outside air or to an adjacent room  
which itself has a permanent vent of the same size  
direct to the outside air. The fitting of an extractor  
fan to either of these rooms is not recommended.  
ACCESS TO THERMOSTAT  
Care should be taken to make sure that the hinges  
are not damaged during installation.  
A gap of 125mm around the body, and 100mm to  
the rear of the stove is necessary to enable access to  
service & repair the thermostatic control system.

INSTALLATION  
MULTIFUEL GRATE  
GRATE BAR REPLACEMENT  
After extended use it may be necessary to replace  
some of the grate bars. Periodic inspection of the  
bars is recommended and the removal of any nails  
or wire that may be present after burning wood.  
All the grate bars in each appliance are identical  
and can easily be lifted out after removal of the fuel  
retainers.  
All bars in the grate are identical, but every other  
bar is turned through 180 degrees, with the ends of  
the bars marked "H" sitting on the high sections of  
the comb, and the ends marked "L" sitting on the  
low sections.  
ASSEMBLING THE GRATE  
To assemble the grate, fit bars to low sections of the  
comb first, inserting end marked "H" into rear  
channel with groove on underside of bar located on  
upstand tab, and then lowering end marked "L"  
onto the low section of the comb. The upper bar is  
fitted in a similar manner, but with the end marked  
"L" inserted in the rear channel, and the end  
marked "H" seated on the high section of the comb.  
Remove damaged grate bars and replace with  
casting of the same type, fitting as per instruction  
above. (Check Identification letters on the casting  
when reordering).  
THROAT PLATE INSPECTION  
The throat plate for all types of fires consists of a  
profiled steel plate with "drop down" facility for  
inspection purposes.  
THROAT P LATE GUIDE  
THROAT P LATE  
OP ERATING TOOL  
To "drop" the throat plate (Fig.8), engage the  
operating tool behind the downstand tab marked  
"throat plate" and pull the plate frontward until its  
forward lugs drop into the cut-away at the front of  
the side panel. Check the upper surface for soot, ash  
build-up, etc. Reverse the procedure to return the  
throat plate to the working position.  
Warning: If the fire is operated with the throat  
plate in the down position the air wash will not  
operate effectively.

INSTALLATION  
FITTING THE FLUE OUTLET AND  
HOT PLATE  
FLUES AND CHIMNEYS  
Please remember that chimney draught is  
dependent on four main factors:  
The flue outlet spigot is found inside the appliance.  
The hot plate (blanking plate) is supplied fitted to  
the top opening and is removed by turning  
clockwise (as is the flue outlet).  
• Flue gas temperature.  
• Flue height.  
• Flue size.  
• Flue terminal.  
Smear a very thin layer of fire cement on the faces  
of the flue outlet and the blanking plate. Fit the  
outlet to the appliance in the desired position.  
The stove must be connected to a suitable and  
efficient flue that provides a good updraught to  
safely take the products of combustion (fumes)  
from the stove outlet to the outside air. To ensure a  
good updraught it is important that the flue gases  
are kept warm and that the flue size suits the stove.  
Lock into place by rotating anti-clockwise and  
tighten by tapping with a block of wood and mallet  
from the inside of the appliance. Similarly, fit the  
blanking plate to the unused opening. Clean off any  
surplus fire cement.  
The termination of the outlet at the top of the flue  
also needs to comply with the Building  
Regulations. The minimum effective height of the  
flue must be at least 4.5 metres from the top of the  
stove to the top of the flue outlet. When warm the  
flue draught should be between 0.1 and 0.2 mb.  
Place appliance on the hearth and make sure that it  
is level and does not rock.  
Connect the chimney ensuring all joints are sealed  
with fire cement.  
A chimney may comply with the regulations but  
still be subject to down draught and similar  
problems. A chimney terminating above the ridge  
level is generally less likely to suffer such  
problems.  
If a new chimney is being provided it should fully  
comply with the relevant Building Regulations that  
specify the requirements for solid fuel burning  
installations. Suitable types of chimney include the  
following.  
*NOTE  
THE FLUE PIPE MUST BE FITTED INSIDE THE OUTLET SPIGOT

INSTALLATION  
Due to the gradual introduction of European  
Chimney Standards chimneys will be specified  
according to their performance designation as  
defined in BS EN 1443 that covers the General  
Requirements for chimneys. The minimum  
performance designation required for use with solid  
fuel burning stoves is T450 N2 S D3.  
Chimneys should be as straight as possible.  
Horizontal runs should be avoided except where  
the rear outlet of the appliance is used, in which  
case the horizontal section should not exceed  
150mm (6'') in length.  
If the fire appears to be working hard but produces  
very little output to the room it is likely that  
excessive draw is present in the chimney, and that  
heat is being sucked out of the appliance and up the  
chimney. If this is the case we recommend the  
fitting of a draught stabiliser in preference to a flue  
damper, in the interest of safety and efficiency.  
The flue and chimney installation must be carefully  
checked by a competent person before fitting the  
stove to ensure it is suitable and will work safely.  
If the chimney is old (ie built of brick or stone  
without a liner) or being opened up for reuse  
additional checks and smoke testing as described in  
Appendix E of the Approved Document J 2002  
Edition should also be carried out to ensure the flue  
and chimney are in good operating condition.  
We do not recommend the use of a damper when  
burning solid fuel.  
FOR ALL APPLIANCES  
Access for cleaning the flue should be incorporated  
in the system other than through the appliance (e.g.  
a soot door or access through register plate).  
Purpose-made soot doors and inspection lengths  
are available from manufacturers of all systems.  
Unless the existing flue is in good condition with  
suitable access for collection and removal of debris.  
If the flue size is more than 225mm (9 inches)  
diameter or 200 x 200mm square, a suitable lining of  
150mm (6 inches) diameter should be fitted, or if the  
flue length is over 5.5 metres one size larger than the  
appliance outlet should be fitted. This should be a  
double skin stainless steel flexible flue liner that is  
independently certified for use with solid fuel.  
Details of suitable linings for use with solid fuel are  
given in the Official HETAS guide that can be  
Ensure that the whole length of the flue can be  
reached from the soot door.  
Note: if the appliance is fitted with a draught  
stabiliser or if one is fitted to the flue pipe or  
chimney in the same room as the appliance, then  
the permanent air entry opening (or openings)  
should be increased by 300mm2 for each kW of  
rated output.  
It is also important that suitable flue pipe  
complying with the Building Regulations is used to  
connect the stove to the flue in the chimney and that  
suitable access is provided into the flue for regular  
inspection and sweeping of the flueways.  
For advice on flues and chimneys contact;  
NACE (National Association of Chimney  
Engineer): telephone 0800 0924019  
The installer should comply with the Building  
Regulation requirements in respect of providing a

INSTALLATION  
To fit/remove thermostat on Tf models  
INTEGRAL BOILERS  
Integral boilers should be connected, with flow and  
return connection of any circuit on opposite sides  
of the appliance, (cross flowed), to an indirect hot  
water tank/system, adding Fernox or similar  
corrosion inhibitor to prevent corrosion and the  
formation of lime scale.  
For fitting/removal of thermostat on Ti models  
please see page 20.  
1. Pull thermostat knob off of the shaft.  
2. Remove access cover plate, use a No. 2 Pozi  
screw driver and remove the 2no. CSK M5 screws.  
It is also essential that the return water temperature  
remains in excess of 45 degrees centigrade  
(Celsius). The gravity return should be fitted with a  
thermostat, which will activate a cut-out on the  
radiator circulating pump, should the temperature  
drop below this level.  
3. Remove the 2no. M5 screws that secure the  
thermostat housing. The thermostat is now free, and  
you will be able to remove the spacer bracket.  
4. On the rear of the stove, remove the thermostat  
sensor from its pocket and push this carefully  
through the hole in the corner cut-out of the stove.  
Take care not to kink the copper tube.  
Connect pipe work to the boiler unit.  
The connected pipes should be screwed to a  
maximum depth of 15mm from the face of the  
tapping, (female 1" B.S.R). Steel integral boilers  
should be connected to an indirect hot water tank  
system.  
5. Withdraw the thermostat from the apperture.  
6. If you are fitting a new thermostat you will need  
to remove the knob extension shaft. Use a 7mm  
spanner. To remove the M4 Grub screw.  
Note: the flow and return sections of any circuit  
must always be opposite of appliance. Remember  
to incorporate a draining plug/tap at the lowest  
point to facilitate drainage & flushing.  
7. Re-fit is the reverse of the above process. Please  
ensure the spacer bracket is secured beneath the  
thermostat as in point 3.  
Warning: if a pipe stat is not fitted then cold  
water corrosion can occur.  
See below if adjustment is required.  
FAILURE TO COMPLY WITH THESE  
REQUIREMENTS WILL INVALIDATE THE  
GUARANTEE  
ADJUSTMENT OF THE  
THERMOSTAT  
However, it is advisable to check the cold setting  
distance prior to lighting a fire in it. With the  
control set at maximum there should be a gap of  
23mm between the fire and the edge of the damper  
plate furthest from the control shaft. If this is not  
the case adjust by slackening off the lock nut and  
turning the adjusting nut on the damper plate.  
When the cold setting distance has been correctly  
set re-tighten the lock nut.

ADDITIONAL INFORMATION  
FOR INSET STOVES (Ti40B)  
BUILDERS OPENING / CHIMNEY  
BREAST  
Stratford Ti 40 fires are designed to be fitted into a  
rectangular recess not less than 400mm (15 3/4'')  
deep, not less than 400mm (15 3/4'') wide and not  
less than 550mm (21 1/2'') high, the so-called  
"standard builder's opening".  
The fireplace surround should be vertical, and with  
a flat surface against which the unit can be sealed.  
The height and width of the flat surface required  
will vary according to the model being installed.  
Where the unit is to be fitted into an existing  
opening it will normally be necessary to cut a hole  
through the chimney breast so that a flue connector  
can be fitted between the appliance and the  
chimney flue. Avoid damaging the lintel.  
For boiler models it may be necessary to cut access  
holes through the side(s) or the chimney breast, so  
that flow and return pipes can be connected to the  
appliance.  
If the cold setting does require adjustment it will be  
necessary to remove the front trim to give access to  
the thermostat. To do this first remove the control  
knob from the thermostat shaft, then slacken the  
screws, which fix the casing to the unit front (a  
screwdriver can be inserted through the slots on the  
radius corner of the casing): the back of the casing  
laps over the flange of the unit front. Lift the casing  
and pull forward to remove. Adjust the setting by  
slackening off the lock-nut.  
Replace the casing on the unit front and refit the  
control knob on to the thermostat shaft.  
INSTALLATION  
Fill the space around the appliance level with the  
top unit with Vermiculite cement (6 parts  
Vermiculite granules to 1 part Portland cement).  
The flue socket in the appliance is designed to  
receive 5'' or 6" nominal cast iron or heavy duty  
steel pipe connector which should be caulked with  
asbestos rope and fire cement.  
FLUE  
If using an insulated steel flue ensure that the  
manufacturer's directions are followed. Take  
special note that the first 450mm (18'') of the flue  
should be single skin cast iron or heavy-duty steel  
flue.  
The length of the connector pipe will be dependent  
on the distance between the top of the appliance  
and the bottom of the chimney but should be at  
least 300mm (12").  
Fill the remaining space around the connector with  
the Vermiculite cement to a level where the pipe is  
effectively sealed in the chimney flue, ensuring that  
the flue gases can only be discharged into the flue  
way. Reinstate brickwork to chimney breast and  
make good. Remember to make provision for  
access to boiler connections for routine  
observation/maintenance.  
When a flue lining is fitted (to stainless steel or  
pumice chimney systems) it should be supported  
independently to the appliance, i.e. with clips,  
brackets, flue lintels, etc. NOT simply resting on  
top of the appliance. It should be possible to  
remove the fire for major maintenance work.  
CHECKING THE THERMOSTAT  
Remove the thermostat knob by pulling off, lift  
the side panel up and pull to the left to replace  
the opposite side repeat the above exercise.  
Replace parts previously removed and check unit  
thoroughly.  
The control knob which is inside the fire for  
despatch is fitted on to the shaft through the hole in  
the left hand casing. It is however, advisable to  
check the cold setting of the thermostat before  
installing and running the appliance. This is best

effective circulation can occur around the primary  
circuit to carry heat away and thus stop boiling.  
WATER CONNECTIONS  
Heating systems  
The output of any radiator installed as a "heat leak"  
should not be less than 10% of the rated output of  
the appliance. The radiator should not be fitted  
with a control valve.  
The cylinder must be of the indirect type with a  
minimum capacity of 110 litres, conforming to  
BS 1566 part 1.  
Primary flow and return pipes should be 28mm  
diameter. The cylinder should be installed at a  
higher level than the appliance, and as close to it as  
possible (the higher the cylinder the faster the  
circulation). The flow and return pipes should not  
be longer than 20ft each. Pipe runs should rise  
continually from the boiler to the cylinder.  
A radiator of approximately 25 sq.ft. should be  
connected into the primary circuit, if installed in the  
bathroom it provides a means of drying towels in  
the summer.  
The size of the heating system which can be run,  
will depend on the output rating of the appliance.  
It will be necessary to work out heat loss  
calculations for the system proposed in order to  
establish the kW/hr rating. An appliance that will  
meet this figure can then be chosen; (for boiler  
outputs please refer to the brochure).  
The constructional requirements of installing and  
connecting the appliance also need to be taken into  
account when selecting. Design and calculations  
for individual heating systems should be carried out  
by a qualified heating engineer. In many cases your  
supplier will be able to offer advice and assistance.  
Direct Systems  
Stainless steel boilers, either factory fitted or  
retro-fitted as add-in boilers enable connection to  
direct systems to be made without the need to  
change the cylinder or to fit an expansion tank.  
This applies to domestic water supply only and  
should not be done when in an area with soft  
water.  
Safety Vent Circuit  
This circuit consists of a cold feed pipe, expansion  
pipe, and expansion tank. The possibility that water  
may boil can never be completely ruled out, and it  
is therefore vital to ensure that cold water can be  
supplied to the boiler and steam vented from it at all  
times.  
If radiators are used then an indirect system must be  
utilised.  
To connect the cylinder use 28mm copper pipes.  
Ensure that the pipes rise continuously to the  
cylinder.  
The expansion tank should have a capacity of at  
least 7 % of the system's water capacity. The cold  
water feed pipe should be at least 22mm diameter.  
Ensure that the runs are not too long, i.e. 20ft  
maximum each for flow and return. Install the  
cylinder above the level of the fire, and as close to  
it as possible. (the higher the cylinder the faster the  
circulation). Ensure that no valves are present in the  
circulating pipes.  
There must not be any shut off valves in the circuit.  
Pipes should be run to avoid air locks. A safety  
relief valve should be fitted to the expansion pipe  
close to the boiler.  
It is often possible, and is good practice, to utilise  
the primary flow and return as part of the safety  
circuit. The ball valve should have a copper ball.  
The overflow pipe from the expansion tank should  
be 28mm diameter copper. Pipes in unheated
