COMMISSIONING
To commission:
• Replace the firebricks, baffle, and log retainer
• Check the door alignment and catch operation, adjust if required
• Check the soundness of door seals, castings and joints
• Check the operation of the air controls
Now carry out a final smoke draw test:
• First warm the flue with a blowlamp, or similar, for about 10 minutes
• Place a smoke pellet on the centre of the grate, with the air controls open
• Close the door
Smoke should now be drawn up the flue and be seen to exit from the flue terminal
• Complete test with all doors and windows closed in the room where the appliance is fitted
• If there are any extractor fans in adjacent rooms, the test must be repeated with the fans running on
maximum and interconnecting doors open
• Check the effect of ceiling fans during the test
If the test fails, re-check the suitability of the flue system and ventilation. An inadequate air supply to
the room is potentially dangerous.
• Light the appliance and slowly increase the temperature to operating levels
• Ensure no combustion products enter the room
• Open the main fire door when the appliance reaches operating condition and carry out a spillage test
with a smoke match or pellet around the door opening
If excessive spillage occurs:
• Allow the appliance to cool and re-check the flue system and ventilation
Finally:
• Explain the safe operation of the appliance and the use of the controls to the user and the
importance of only using suitable fuels
• All open flue appliances can be affected by temporary atmospheric conditions which may allow
fumes to enter the house. Because of this it is recommended that an electronic carbon monoxide
detector conforming to BSEN50291 be fitted and maintained.
