5 TROUBLESHOOTING
5.1 Backdraft / Smoking
Draft is the force created by a difference in pressure, which moves air from the appliance up through the chimney.
It is important to operate the FLAIR with proper draft to ensure optimal performance of the unit. Draft is depended
on the length of the chimney, local geography, nearby obstructions and other factors. Proper draft results in an
upwards flow through chimney, which prevents smoke infiltrating into the house during operation of the unit. As
the temperature of the unit and chimney rises during combustion, the draft consequently increases due to a
higher difference in pressure.
In contrast, backdraft is air flow from the chimney into the house, which results in smoke infiltration from the
appliance and/or the chimney joints during operation. The unit is experiencing backdraft if air is flowing out from
the exhaust of the baffle system (within the firebox). Backdraft is most commonly caused by fans around the
house (such as in the kitchen and bathrooms) simultaneously in operation, another fireplace/stove within the
household in operation, insufficient length of the chimney (less than 15 feet), inadequate ventilation, or a blocked
chimney. Refer to the following suggestions to eliminate backdraft:
•
Close any fans operating around the house (specifically for the duration of ignition).
•
Clean the chimney of any obtrusions (when the unit is cold).
•
Open one window or one door near the FLAIR.
•
Heat the chimney.
5.2 Over Firing
The appearance of a red glow on the exterior of the firebox (top and sides) and/or on the flue is a sign of over
firing. Excess air entering the firebox, over fueling, or an abnormal strong draft causes the unit to reach drastic
temperatures from an uncontrollable combustion. Over firing is a safety hazard and may result in permanent
damage to the unit. In the occurrence of over firing:
a) Make sure the FLAIR door is properly closed.
b) Manually close the Combustion Air Control by pulling the Activator (left lever).
c) Turn on the blower to the maximum speed. The red glow on the exterior of the firebox and/or the flexible
liner should gradually disappear.
WARNING: Do not touch hot surfaces with bare hands. Always wear heat protecting gloves and use
fireplace tools.
WARNING: Failure to follow the above guideline will void the warranty. Over firing is a safety hazard, can
cause irreversible damages to the FLAIR and will void the warranty.
Guideline to avoid over firing:
•
Always keep the door closed during operation.
•
Inspect regularly the door gasket/glass and replace accordingly.
•
Always operate the unit with the chimney sweeping cap in position, blocking
the hole in the baffle.
•
Never load more than 32 lbs of wood at a time.
•
Ensure that there is no excess draft.
