Flex Fuel Owner’s Manual
March 2011
Possible reasons why an ignition fault may be caused:
• The ash chamber or flue pipe is covered in ash.
• The ash door and/or firebox door are not fully closed.
• The pellets insert is contaminated with dirt and should be cleaned.
• The igniter is defective.
• One (or more) conveyor screws are defective (pellet arm, hopper screw).
• The installation was not approved by WoodMaster. The commissioning procedure should be per
formed to ensure optimum system operation.
Before restarting the furnace after the ignition fault has been rectified, ensure there are no unburned
pellets in the insert. If this is the case, clean the grate before restarting the furnace.
Feed blocked or overloaded!
The furnace is currently in automatic mode (Pellets) and the feed is blocked (current draw too high) or is
overloaded (no current draw). If this error is detected more than once, the furnace turns off.
Fan lag! Please wait!
Fan lag has been activated for no apparent reason. Possible causes:
• Power outage
• The safety temperature limiter tripped and has just been reset.
Wait for the run-on cycle to finish (10 – 30 minutes), the furnace will automatically start afterwards.
Note: Fan lag cannot be aborted! The run-on timer is restarted after every power outage.
It can therefore not be shortened by unplugging the mains connector.
Monitoring deactivated!
Flue gas and air factor monitoring was deactivated in “Pellets mode!” or during the “Start phase!”. The
firebox doors can now be opened during operation without the furnace shutting itself
down. The monitoring function is automatically reactivated after 5 minutes or manually activated by
pressing and holding the ESC button.
Safety chain is open!
Your furnace is fitted with a safety chain that is currently open. This safety chain is attached to sensor
input “Circulation sensor” on the I/O Board (section 5.6). Close the safety chain and the furnace will
automatically start.
