üCheck the Exhaust Blower voltage across the blower wires (>=114V on #5 setting and >= 82V on #1 setting).
– Replace the Circuit Board if the Voltage reading is less than 82V. with a line voltage >115Vac.
üCheck Vacuum levels in the exhaust channel by bypassing the Vacuum Switch, then remove the Vacuum hose from
Vacuum Switch. Check exhaust vacuum readings by placing the open end of the Vacuum Hose on a Magnahelic
Gauge (readings must be above .10” W.C. on low fire).
If the motor fails to reach a 0.10” w.c. readings, then replace the Combustion Blower.
üPoor Quality Fuel – Insufficient energy in the fuel to produce enough heat to keep the stove burning or
operational.
üExhaust Temperature Sensor failure. – Bypass sensor located on Exhaust Blower if stove now operates properly,
the unit may require cleaning or a new sensor. Contact your local dealer for service.
The exhaust motor will not function normally
üOpen the left side access panel; check all connections against the wiring diagram.
üSee above section.
Light # 2 on Heat output bar flashing – The Vacuum Switch contacts have opened for more than 15 sec.
üPinch, break or blockage in Vacuum Hose - Check hose for pinch points or damage, replace or re-route as
required. Blow out Vacuum Hose
üBlocked Hose Barb on Exhaust Channel - Use a paper clip to clean out Hose Barb or remove the Vacuum Hose
from the Vacuum Switch and blow into the hose to remove blockage.
üBlocked exhaust / venting system - Have stove and venting cleaned and inspected.
üSevere negative pressure in area where unit is installed - Check the operation by opening a window, does this
solve the problem? If it does, install fresh air intake to unit or room. Venting system may require vertical section to
move termination into a low pressure zone.
üVacuum Switch failure - Bypass the vacuum switch, if this corrects the problem check for above problems before
replacing the Vacuum Switch.
üDamage to gray wires between Circuit Board and Vacuum Switch - Inspect wires and connectors
üCombustion Blower failure - The Combustion Blower is not turning fast enough to generate the proper vacuum
in the Exhaust Channel. Visual Check; is the blower motor turning? Check the Exhaust Blower voltage across the
blower wires (>=114V on #5 setting and >= 82V on #1 setting). Replace the Circuit Board if the Voltage reading
is less than 82V. with a line voltage >115Vac.
