Charnwood Grosvenor  
Operating Instructions  
Please go through this section with the installation  
engineer so that you fully understand all the basic  
operating and maintenance procedures for your stove.  
a. Switching On/ Ignition.  
Depress the control knob and turn counter clockwise. Gas  
will flow to the pilot burner, the piezo igniter will give off  
a high voltage spark & the pilot burner will light. (More  
than one attempt may have to be made on first lighting the  
fire.) Keep the control knob depressed for approximately  
10 seconds to heat up the thermocouple, Turn the control  
knob fully counter clockwise to release gas to the main  
burner.  
The engineer will be happy to answer your questions and  
give you any help you may need.  
General Notes  
This stove is not for use with any solid fuels. It is only  
suitable for Natural (mains) Gas or LPG (Liquified  
Petroleum Gas) when the correct burner is fitted.  
Please remember that when the stove is alight it is very  
hot.  
b. Control of Gas Flow.  
Turning the control knob clockwise reduces the gas rate  
from the maximum to the pre-set minimum setting.  
Turning between maximum & minimum does not actuate  
the piezo igniter. The control valve can only be set on pilot  
by depressing the knob & turning it to the pre selected  
pilot position.  
EXCEPT FOR THE CONTROLS NEVER TOUCH  
THE STOVE WITH YOUR BARE HANDS WHILST  
IT IS HOT.  
The stove must not be touched when it is in operation.  
However, if you do need to do so after it has been turned  
off and before it has completely cooled down (usually after  
about one hour) please make sure that you wear stout oven  
gloves.  
Flue Spillage Safety Monitoring Device  
A Safety Cut-Off System.  
All stoves are fitted with an Oxygen Depletion Sensitive  
Pilot so that should the flue and/or chimney become  
blocked at any time, the stove will automatically cut off.  
Normally the pilot can be re-ignited after waiting about  
five minutes for the sensor to cool down, but in the event  
of the system tripping, have the flue and chimney checked  
by your installation engineer.  
Control Knob  
Lighting and controlling the stove.  
Remember that the stove is designed to be operated with  
the door and spinwheel securely closed.

Should the stove burner cut out for any reason you  
should not try to re-light it for at least 5 minutes. If you  
are then unable to re-light the pilot as described earlier  
you should contact your stove supplier or engineer.  
To The Customer  
PLEASE READ THE FOLLOWING PROCEDURES AND  
SERVICE CHECKS BUT PLEASE NOTE THEY MUST  
ALL BE CARRIED OUT BY A QUALIFIED INSTALLA-  
TION ENGINEER. IF THE DOOR GLASS BECOMES  
DAMAGED OR BROKEN-DO NOT USE THE STOVE.  
During normal operation, for example in the winter  
months when the stove will be in regular use, we advise  
that the pilot is left running continuously as this will allow  
for quick and easy lighting, while at the same time helping  
to prevent condensation. When the stove is not being used  
for long periods, i.e. in the summer then we advise that the  
gas supply is turned off at the isolation tap.  
Glass Replacement  
1. Before carrying out the glass replacement we suggest  
that, for safety reasons, the gas supply is turned off at the  
isolation tap.  
PLEASE NOTE: When the stove is first operatedit  
should be run at its maximum setting for several hours to  
help the painted coating to cure. However, if you are able  
to run the stove for a minimum of four hours then the full  
curing process will be completed.  
2. When the stove is cold remove door: See stove assembly  
instructions.  
3. Protect the working surface by laying the door on plenty  
of newspaper or cardboard.  
While the paint is curing there may be a little smoke given  
off the surface of the stove accompanied by a slight smell  
and traces of vapour. This is perfectly normal and quite  
harmless. However, for your own comfort keep the room  
well ventilated until the curing process is completed. The  
slight smell may linger for the first week or so of  
operation.  
4. Remove all glass securing clips and all the broken glass.  
5. Fit the new glass, ordered from your stove supplier,  
ensuring that the sealing cord is correctly positioned  
between the glass and the cast iron door frame. If this  
sealing cord is damaged in any way a replacement can be  
obtained from your stove supplier.  
6. Re-secure the clips and nuts. Do not over-tighten as this  
could crack the glass. We suggest hand tight, just enough  
to ensure a good seal.  
Customer Reminder  
IT IS A LEGAL REQUIREMENT THAT THE  
COMPLETE ASSEMBLY, INSTALLATION AND  
COMMISSIONING OF GAS FIRED STOVES IS  
CARRIED OUT BY A PROFESSIONALLY QUALIFIED  
AND ACCREDITED GAS FITTER. YOU MUST NOT  
ATTEMPT THIS YOURSELF.  
7. Re-fit the door making sure it is securely closed, before  
re-establishing the pilot light as described above.  
Fume Spillage Check  
This test must be carried out by the installation engineer  
when the stove is first commissioned and then we suggest  
every 12 months to ensure that the products of combustion  
are not spilling into the room. The test is carried out by  
running the stove for ten minutes and then holding a  
smoke match close to the diverter box to make sure the  
smoke is drawn up the into the flue way. Do not use a  
lighted match or a naked flame. The air flow must be  
drawn to the chimney with sufficient draught. If the smoke  
is disturbed then repeat the test a few minutes later. If the  
smoke is still disturbed by escaping products of combustion  
turn the stove off and contact your installation engineer  
MAINTENANCE & SERVICING  
PROCEDURES.  
Stove Cleaning  
The stove surfaces are treated with an extremely durable  
high temperature resistant paint cleaned by brushing down  
with a clean shoe brush. If any of the black paint should  
need retouching you can obtain the correct paint from your  
stove supplier. Don't wash the stove or let water remain on  
any surface when it is cold as this may cause rusting.  
Regular Servicing For Safety And  
Efficient Operation.  
Glass Cleaning  
Under normal use the glass should remain clean. However,  
if the glass needs cleaning, this can easily be done with a  
suitable glass cleaner available from your stove supplier.  
Servicing should be carried out annually by a qualified  
installation engineer when the stove is cold and the gas  
supply turned off at the isolation tap. The following points  
should checked:  
1. Remove all the coals and clean any dust and debris from  
Page 4

the top of the burner unit. Ideally a vacuum cleaner should  
be used, but if not a soft brush will do.  
We hope these instructions have been clear and helpful and  
you are now able to enjoy the full benefit of your stove. If  
you have any queries or have found any part not as straight  
forward as you would like, then please don't hesitate to call  
us. Any suggestions for improvements are most welcome.  
2. Check the condition of the coals. Any damaged ones  
will affect the efficient operation of the stove and should be  
replaced with new ones available from your stove supplier.  
Please keep these instructions handy for future reference.  
Most Important: Before installing the stove, check the  
burner data plate, this must correspond with the type of gas  
which is to be used, i.e. Natural Gas or LPG.  
3. All gas joints should be checked to make sure they are  
completely sealed and that the gas supply and pressure is  
to specification.  
4. The pilot jets are correctly set and clear of obstruction.  
5. The chimney should also be checked to make sure there  
are no restrictions or blockages.  
6. Finally re-lay the coals and light the stove as described  
earlier.  
Problem Solving  
Although we recommend that the customer is familiar with  
the following it is important that the installation engineer  
is contacted to rectify any difficulties.  
The gas pilot will not stay alight:  
1. Ensure there is a gas supply to the property and that the  
isolation tap is in the "on" position.  
2. Hold the control knob in the lighting position for at least  
20 seconds once the burner is alight, to ensure adequate  
heat operation of the safety thermocouple valve.  
3. Make sure that the pilot injector is not obstructed or  
blocked and that it is free from dust or dirt.  
4. Finally ensure that the thermocouple, a very delicate  
electro-mechanical device, has not become damaged in any  
way. If it is damaged a replacement pilot assembly should  
be obtained and fitted by your installation engineer.  
FINAL REMINDERS  
We remind you that it is a legal requirement that the stove  
is installed by a qualified and accredited installation  
engineer. Improper installation, adjustment, alteration,  
service or maintenance can cause injury and/or damage to  
property.  
If you are in the slightest doubt about any aspect of your  
stove's performance or you require additional information  
then please contact your stove supplier or qualified  
installation engineer.  
At the risk of stating the obvious, please do not store, keep  
or use petrol or any other flammable liquids, vapours or  
substances anywhere near the stove or any other heating  
appliance.

Installation Instructions  
Notes to the Installation Engineer: Please make sure the  
And Fire Opening Specification.  
The location of Charnwood Grosvenor model stoves  
should have the following space around them:  
The hearth should protrude at least 150mm (6”) in front of  
the stove body and be at least 12mm (1/2”) thick.  
customer is familiar with the initial lighting and operating  
procedures before leaving the site and that this instruction  
booklet is left with them when the final commissioning is  
complete.  
Please check that the following components are included  
before you start on the assembly.  
In most buildings with solid concrete floors this  
requirement will have been met by the floor itself. There  
should also be a gap of at least 150mm (6”) on either side  
of the stove, more if possible as the greater the space the  
greater the amount of heat being released into the room. If  
the stove is to be fitted into an existing opening there  
should be a minimum of 150mm (6”) clearance on both  
sides, with the back of the flue diverter box 15mm clear of  
the rear wall.  
The following stove components are delivered in 2 boxes:  
Box 1: 1 Stove Body inc. baffle and flue diverter.  
Box 2: 1 Burner Unit and coal set.  
Assembly  
IMPORTANT: ENSURE THAT THE CONCEALED  
DOOR LOCK IS REMOVED BEFORE ATTEMPTING  
TO OPEN THE GLASS DOOR USING THE HANDLE .  
On all stove installations no combustible material should  
cover the hearth, or be placed any closer then 225mm (9”)  
from the stove. This includes carpeting and other  
combustible floor coverings.  
* Remove spinwheel from the bottom centre of door.  
* Remove the lower bolt, using a 13mm spanner or socket,  
and retain.  
Connection To The Chimney.  
Use 125mm dia. flue pipe to make the chimney connection.  
If required, 100mm dia flue pipe may be used.  
* Open door using handle and remove contents packed  
inside stove, including front fire bar, noting location for  
reassembly.  
Before you install the stove make sure the chimney flue  
outlet is correctly positioned to align with the flue outlet on  
* Fit draught diverter to rear of stove using nuts and bolts  
provided.  
* Fit baffle plate by locating on the 4 lugs inside body with  
the curved edge towards the front of body curving upwards  
as shown in Fig. 2.  
Baffle Plate  
* Insert burner through door aperture with valve on right  
hand side.  
* Manoeuvre burner and locate so that rear lugs fit over  
rear base plate: front lugs sitting on front of base plate and  
secure with two bolts through top of base plate, the gas  
valve will then be neatly located through cut out in right  
hand side of stove body.  
Flue Spillage Monitoring System.  
Charnwood Grosvenor stoves are fitted with an oxygen  
depletion sensitive pilot.

the stove and that the chimney is in good condition. If not,  
a chimney liner must be installed or a suitable class 2 gas  
flue used. An up-draught is necessary to ensure the  
products of combustion are fully evacuated.  
Gas Pressure.  
Make sure that there is adequate gas pressure and volume  
to the stove. The relevant pressures are on the data plate.  
The stove must be installed in accordance with current gas  
and building regulations applicable.  
Ensure that the gas pressure to the stove is maintained  
when it is operating at the same time as other appliances  
in the building.  
Connect and seal the stove flue collar to the chimney with  
a length of pipe fitting for a depth of at least 20mm (3/4").  
A minimum of 610 mm (2ft) of vertical pipe should be  
established before the flue direction is changed, unless the  
stove is to be used with a fanned (powered) flue.  
The gas pressure can be obtained by unscrewing the  
pressure test nipple and applying a suitable pressure gauge  
i.e. a manometer.  
Pressures to be as stated on the data plate.  
The flue must have a minimum height of 3 metres (10ft),  
however to ensure optimum performance we recommend  
3.6 metres (12ft) or higher. The flue must be free of  
obstruction and any dampers must be fixed in a  
permanently open position. Ensure the chimney is not  
closed and that it has been swept prior to the stove being  
installed.  
Before any coals are placed in position make sure that the  
burner is operating correctly. The flame should be fairly  
even across the burner top.  
Ventilation  
Under normal circumstances no additional room  
ventilation is needed.  
Make sure that rain, birds or any foreign body cannot get  
into the chimney to cause damage or a blockage. This  
problem can normally be overcome by fitting an approved  
Gas Cowl. It is essential to the effective running of your  
stove that the chimney draws properly to allow the  
products of combustion to escape.  
Coals Layout  
The approved layout of the coals is shown in Figs. 3, 4, 5  
and 6. Adjustments may be made on this basis to give a  
beautiful looking fire. Spare coals are provided in the pack.  
Gas Connection.  
Pre Lighting Checks  
1. All building work and flue sealing is complete.  
2. The front fire bar is refitted in position.  
3. All the coals are correctly placed.  
The gas supply must be properly sized to provide the  
correct gas rate at running pressure when measured at the  
inlet valve. The final connection to the stove must be made  
with a suitable 8mm dia gas pipe.  
It is essential that a gas isolation tap is provided upstream  
of the stove, in a position that is easily accessible.
