USER INSTRUCTIONS
— Difficulty getting a fire going and keeping it burning well
(low flue draught)
6. BURNING TIPS
— Low heat output (low flue draught)
— Smoke entering room when doors opened (low flue
draught)
6.1 Fuel Quality (Wood)
Use wood with a moisture content of less than 20%.
Seasoned logs have the bark beginning to lift and peel away
and cracks radiating from the centre. They feel lighter than
fresh cut wood of a similar size and sound hollow when
struck against each other. Logs should not feel damp or
have moss and fungal growths.
The construction, position, size and height of the chimney
all affect the performance of the flue draught.
Other factors effecting the flue draught include:
— Trees or other buildings nearby causing turbulence
— High and gusty winds
Symptoms related to wet wood:
— Difficulty starting and keeping a fire burning well
— Smoke and small flames
— Outside temperature
— Outside weather conditions
— Dirty glass and/or firebricks
— Rapid creosote build-up in the chimney
— Low heat output
— Short burn times, excessive fuel consumption and
blue/grey smoke from the chimney
— Incorrect additional ventilation to building
— Blocked flue / chimney
For advice on the correction of persistent flue problems
consult a qualified solid fuel heating engineer before
continuing to use the appliance.
• Burn at high output at high output for a short period each
day to avoid large build-ups of tars and creosote within the
appliance and the flue system
• Use Stovax Protector chimney cleaner to reduce this
problem
6.5 Weather conditions
The weather conditions outside the building can effect the
burning performance of the appliance. These could include:
Weather Conditions Problem

around chimney.
Smoky Appliance
• Use recommended solid fuels approved for use with
closed appliances.
Symptoms related to unsuitable fuels include:
— Difficulty starting and keeping a fire burning well
Calm days
Oversized Chimney. Smoky Appliance
— Smoke and small flames
— Dirty glass and/or fire bricks
— Short life span for grate, baffles and internal firebricks
— Permanent staining of glass
Damp / Rainy days
Flue temperature

Rain water inside
chimney.
Lighting and
burning problems
To reduce these problems:
6.3 Air inlets puffing smoke
• Use good quality kindling wood to start the fire
• Burn initially at a high temperature for a short period
• Fit a rain cowl to the chimney
Combustion gases build up in the firebox and ignite as small
explosions, causing smoke to puff out of the air inlets and
other openings. This occurs if the air controls are shut soon
after adding new fuel to a very hot fire. Stop by opening the
air controls to increase combustion air and burning rate.
Your installer should advise you on possible solutions.
If the appliance emits smoke into the room continuously:
• Close the air controls and allow the appliance to go out
• Ventilate the room to clear the fumes
• Leave the room
6.4 Flue Draught
The chimney has two main functions:
1) To safely remove the smoke, gases and fumes from the
house.
2) To provide a sufficient amount of draught (suction) in the
appliance ensuring the fire keeps burning.
Do not re-light the appliance until the problem is solved.
Draught is caused by the rising hot air in the chimney when
the appliance is lit.
Symptoms of poor performance related to flue draught
include:
— Excessive fuel consumption (high flue draught)
— Poor burning control, overheating (high flue draught)
— Wind noise from air controls (high flue draught)

cloth
8.1 It is possible to get the appliance to burn over night.
In order to do this:
• Do not use aerosol sprays near an operating appliance
• De-ash prior to final refuelling
• Set air controls to low combustion settings
This will blacken the glass over night but it will clear when
operated at high output for a short period.
Wipe dry with a soft clean cloth before re-lighting. Do not

painted or metal surface as it can damage the finish.
13. CHIMNEY SWEEPING
13.1 To maintain safe and efficient use of the appliance the
chimney/flue must be inspected and swept at least once a
year by a qualified chimney sweep.**
Your retailer can provide genuine spare parts such as replacement
glass, door sealing rope and fire bricks when required. An annual
service by a competent engineer is recommended to keep your
appliance in best possible condition.
If the appliance is used continuously throughout the year
or it is used to burn wood or smokeless fuel, more frequent
sweeping is recommended.
The best time to have the chimney swept is at the start of
the heating season.
The above applies even if burning smokeless fuels.
13.2 The chimney, any connecting flue pipe and the appliance
flue ways if incorporated, must be regularly cleaned.
13.3 Ensure adequate access to cleaning doors where it is not
possible to sweep through the chimney.
13.4 If the appliance is believe to have previously served an
open fire the chimney must be swept a second time within
a month of regular use after installation.

USER INSTRUCTIONS
• Glass blackening
15. SEASONAL USE
• Thick, brown and sticky tar oozes from the pipe joints
This is caused by burning damp wood and burning your
appliance at too low a temperature;
• Use well seasoned wood and operate the appliance in the
ideal temperature range
Tar is a major cause of chimney fires - if you experience
problems with tar build up consult a chimney sweep before
continued use of your appliance.
15.1 Clean and service the appliance if it is not used during the
warmer periods of the year as detailed in the Maintenance
and Servicing section
15.2 Set the air controls 50% open to keep the appliance
ventilated and stop the build-up of any moisture inside.
15.3 Before re-lighting the appliance:
• Remove the baffles
Ideal working temperature range is 130°C and 240°C
(270°F – 465°F). Failing to close down the primary air
control once the appliance has heated up to this range
may cause the appliance to over-fire and to exceed the
ideal temperature range. Over-firing can cause permanent
damage to the appliance and invalidates your warranty.
• Clear any debris that may have accumulated
• Check the flue is clear of any blockages
16. TROUBLESHOOTING TIPS
16.1 Stove glass blackening:
This has four possible causes:
1.
Incorrect use of airwash – See Sections 1, 4 and 5 for the
correct use of the air controls.
2.
3.
Burning unseasoned wood – See Section 3 to identify
when wood is ready for burning.
Stove operated at too low a temperature - good working
temperature is 300-500° F (120 – 250° C). A stove pipe
thermometer can identify this problem (Stovax part no
3046)
• Burn with the airwash control fully open for approximately
20 minutes to cure this
The problem may be caused by damping your appliance
down overnight.
4.
Problems with the flue – in particular insufficient air pull.
If the flue is not working efficiently the glass can blacken.
A flue which has too much downdraft may be too short or
needs lining or has too many bends. This can also cause
blackening of your stove glass. Contact the installer or a flue
specialist for advice.
16.2 Riddling mechanism jamming:
This occurs when fine ash builds up under the riddling bars
preventing movement. To prevent this:
• Follow a regular cleaning routine for the inside of your
appliance
• Lift out the riddling mechanism and remove all ash
• Replace riddling mechanism when cleaning is complete
16.3 Glass cracking:
Do not over tighten the screws on the glass clips when
replacing the glass as this causes stress and the intense
temperature changes can cause the glass to crack. For
replacement glass contact your local Stovax dealer.
16.4 Appliance is producing tar:
This is identified by:
• A very strong pungent smell shortly after the appliance is
lit and heats up

4. MINIMUM BUILDERS OPENING
6. BUILDERS OPENING
Many fireplace openings have a supporting lintel. Remove
the covering plaster to identify it's position before starting
any constructive work. Do not remove constructional lintels
without making provision to support the remaining structure
of the building. The appliance must not form any part of the
supporting structure.
To make installation easier make the opening larger than
the minimum requirements where possible.
6.1 The chimney/flue must have a sealed connection to the
appliance flue spigot.
6.2 The structure of the builders opening will reach high
temperatures. Use insulating blockwork to reduce the heat
transfer to the external walls, in particular the area of the
chimney breast above the opening.
6.3 Take care when finishing the chimney breast and
surrounding area. The conducted and convected heat
emitted by the appliance could be high enough to crack
normal plaster. Use a high temperature plaster, or face
the area with a suitable high temperature plasterboard.
New plaster should be fully dried before the appliance is
used, or cracking could occur.
Riva 40 only
Riva 55/66/76 only
It is possible to fit the Riva 40 into an existing, traditional, 16”
fireplace opening following the removal of any existing milner
fireback. Following the removal of the fireback and any flaunching
above, the builders opening should be checked and made good to
the dimensions shown in the table. Care should be taken to ensure
the existing chimney is in good condition and that it is possible to
make the required sealed fluepipe connections to this when the
Riva 40 is installed.
If optional convection air ducts are to be used, increase the
opening height by 300mm to enable connection to be made
before final completion of building work.
Riva 66/76 only
Dimension C may be reduced to 355mm when using the
spacer frame kit.
Consideration must be given for the clearance of 20mm
between the flue pipe and lintel/inside chimney breast
