Your furnace is equipped with an air inlet damper/box. The
purpose of this damper/box is to adjust combustion airflow to
match the characteristic of each specific home and chimney
configuration and prevent smoke from flowing back out the
tube during power failures. The damper is preset at the factory
with an adjustment screw (See Figure 12). The damper will
most likely only need a small adjustment during the break in
period. To determine if the damper needs to be adjusted, read
below to see the two areas that need to be observed. during
the adjustments be sure to only make small adjustments and
allow 15-20 minutes before re-evaluating.

ERROR DESCRIPTIONS
Figure 12
LOSS OF POWER
- Loss of Power oc-
curred. Once power is returned the unit will
turn on the combustion blower for 5 hours to
exhaust any possible smoke.
SOLUTION
: Check power connections and
circuit breakers. clear fault and restart unit.
LOSS OF FLAME
- The exhaust temperature
has dropped below minimum temperature.
This is normally due to fire going out.
SOLUTION
: Check burn pot and insure it is
in proper position and verify there is fuel in
the hopper. If unit displays same error when attempting a
restart it may be necessary to replace the switch.
AUGER TIME OUT
- The control board
sensed the auger had not been running for
2 consecutive minutes. This can be caused
by leaving the hopper lid open longer than
2 minutes or the High Limit switch tripping
thus shutting off motor.
SOLUTION
: Verify wires to motor are
not broke or disconnected. Verify the lid was closed and
lid switch is operating. check fan limit switch by removing
cover and ensure dial is not above 200 degrees.
LOSS OF vACUUM
- The unit has sensed
a loss of vacuum.
SOLUTION
: Check to en
-
sure the fire door and ash pan are securely
closed. check that the gaskets are in good
shape. Verify the incoming combustion air
and the exhaust is free of any debris that could interrupt air
flow. Insure air damper is open and Sail switch is swinging
open by looking into the damper opening (outside air will
need to be disconnected). Restart unit to see if the combus-
tion blower starts, if not replace blower. If unit displays the
error again the Sail switch may need to be replaced.
ACTUATOR LIMIT ERROR
-
actuators did not reach their extended or re-
tracted limit in the proper time limit or there
is a loose wire connection.
SOLUTION
: Verify there is not obstructions
in the fire pot keeping the components from moving prop-
erly. Go to the maintenance menu and operate each actuator
individually to ensure freedom of movement. If it fails to move
in either direction the controller or actuator may need to be
replaced. check for loose or disconnected wires to
the actuators.
WARNING
These safety switches are designed to protect life
and property. Bypassing these features voids all
warranties and the safety listing of the furnace.
NOTE: This may take several hours to setup de-
pending on each home. However, once complete
this should not need to be done again. Please be
patient as this is the key to having a proper running
furnace. Do not use damper to adjust Level 1. The
Trim function is used for level one adjustments.
Fahrenheit Technologies Inc. Bio Furnace has been
Safety Tested by an accredited, independent laboratory.
COMBUSTION AIR DAMPER/BOX
Pilot mode or Level 1 will be the most critical during setup.
a bright violent flame can cause fuel to burn out therefore
maintaining a red coal base is primary concern. These
adjustments are to be made with the trim function not damper.
