9.3.10 Combustion Air Starvation

Venting system is dirty. Refer to Section 8: Maintenance.

The flue is not properly installed. Make certain the venting system meets the criteria in the

installation section of this manual as well as the venting system manufacturer's instructions.

Inadequate fuel is used. Remove the burn pot, make sure that all openings are clear and check

that no ash has filled the tube around the igniter. Refer to Section 8: Maintenance. Also, make

sure that recommended fuel is used (see Section 5.2.1 Proper Fuel) and settings are adjusted to

the type of pellets that are being used (see Section 6.1.5 Adjusting the Combustion Level (Heat

Output)).

Air intake channel is restricted. Visually inspect the air intake channel that leads to the burn pot

for foreign material. Make sure that the air-intake shutter is functional and free of any

obstruction.

The combustion/exhaust blower failed. Go to the troubleshooting page on the LCD screen and

test the combustion and the exhaust blowers independently (see Section 9.2 Testing

Components). If one of them does not function, make sure there is power and that the blowers

are properly connected. If they still don't work, check fuse F4 and F5 on the control board. A

blown fuse will be darkened or will have a broken filament. If the fuses are in good condition, the

combustion or exhaust blower is probably defective; Replace the faulty part.

There is no electrical current going to the stove. Check if the stove is connected and if there is

current in the wall outlet. Check if the F7 fuse is blown. Replace it if necessary.

TELCO wire is defective or not connected properly. Convection blower, combustion blower,

exhaust blower and burn pot auger will start but the stove will beep continuously and the LCD

touch screen will remain black. Check connection and change wire, if necessary.

The temperature of the screen is below zero. When the screen is exposed to temperatures too

cold, the liquid crystals may not function properly which causes a loss of communication. This

situation may occur in cases where the unit has arrived from outside by a carrier or is subjected to

a room temperature too low as in an unheated cottage or a very cold garage.
