Flex Fuel Owner’s Manual
March 2011
Note: Always ensure that the insert corresponding to the furnace operating mode is fitted and the
pellet slide and flap (sections 13.3) are in the correct position for the selected mode. Ensure that the
diverting valve has been properly set. (Section 5.4)
13.1 General Information
In operating mode “Pellets auto control” your furnace automatically runs on pellets fuel. The furnace
automatically starts when there is a call for heat. Once the call for heat has been met, the feed of pellets
is stopped and the furnace switches to standby mode. The start screen always indicates the furnace
operating mode which is currently set. If this is not set to “Pellets”, change the furnace operating mode as
described in section 10.
13.2 Pre-Firing Checks
Check the Firebox
Check that there are no foreign objects in the firebox and place the insert for Pellets Mode is in the
firebox. Ensure also that ash residues are removed from the firebox. In particular the insert should be
free from residues so that a down-draft can be guaranteed. The ash residues can be guided into the
ash chamber through the insert using the fire irons.
(Section 15)
Check the Primary Air Feed
To guarantee that your Flex fuel receives the oxygen feed necessary for ensuring clean burning, the two
air deflectors which are located on the right and left furnace side walls in the firebox must be checked or
cleaned with the fire irons. (Section 15)
Check the Ash Chamber
Check that there are no foreign objects inside the ash chamber and that the refractory is not damaged.
Any accessories such as ash trays, furnace utensils, etc. should not be in the ash chamber or firebox
during operation. Remove ash build up if needed. Close the ash door and ensure that it seals properly.
(Section 15)
Check the Pellet Slide
In pellets mode the slide must be installed and can be adjusted with an adjustment screw (section 13.3).
The feeder also has a swivel flap, which must be open for pellet operation.
