Flex Fuel Owner’s Manual
Check Status Line(s)
Before starting the furnace in “Pellets Auto control” the furnace should be switched off.
Check Pellet supply
Your furnace operating mode is “Pellets - Manual Filling” meaning the operator must fill the hopper
manually. Open the cover of the pellet hopper and check the level of the pellets. Fill the hopper if
needed. Remember to check the level of the pellets daily under normal operating conditions.
Check the Insert
Check that the correct insert is installed in the firebox, and that the insert is free from any buildup that
may block air flow. Remove and clean the insert if needed. Below is the correct insert for this operating
mode.
13.3 Adjusting the Pellet Slide
The furnace must be running in “Pellets” mode to preform these adjustments. It is recommended that
there is a call for heat so the furnace will run continuously for an extended period to correctly adjust the
slide. This is intended to be a one time adjustment.
The pellet slide is used to guide the pellets fall into the center of the insert. The slope of the pellets slide
may be set using an adjustment screw which is accessible from the outside wall of the furnace. The lower
panel cover of the pellet feeder must first be removed to access the bolt. Undo the counter nut of
the adjustment bolt (Fig. 1) and then turn the screw to adjust the slope of the pellet slide.
Note: The
adjustment bolt may be hot!
While the furnace is doing its initial fill adjust the slide so that the pellets fall into the center of the grate.
Then close the door to allow the ignition process to start.
Let the furnace run in Pellets mode for one hour and check the pile in the firebox. Do not leave the
firebox door open for an extended period or fan lag may be activated. If it looks like Fig. 2 with a nice
even burn around all the edges of the pile then no further adjustments are needed. If it does not adjust
the adjustment bolt in or out using fig. 3 and 4 as references.
Note: Monitoring can be activated and deactivated the same way Smoldering Gas Extraction
(section 11.4) is activated to prevent the furnace from shutting down and to vent the furnace.
