Start-Up Instructions
For initial start-up after heater installation, follow steps
1-5. For normal start-up, set the thermostat above room
temperature or set thermostat selector switch to the
manual position.
1. This heater is wired with a ground connection for your
protection against electrical shock hazard. The heater
must be connected directly to a properly wired and
grounded electrical supply. (minimum breaker size
must be 20 amp)
2. Set thermostat to desired room temperature or set
thermostat selector switch to the manual position.
3. Position the fuel selector valve as shown for fuel
being used.
This heater is shipped from the factory with the fuel
selector valve in the propane gas (LP)
position. Ensure the fuel selector valve's handle is
properly positioned for the fuel being used.
4. This heater has a rocker style selector switch located
on the side of the heater. This switch allows for either
heat mode or ventilate mode (no heat) .

5. When the switch is set to heat
will be activated in sequence as specifi c circuits are
checked by the heater controller. If the heater does
not light, and a status light is off, refer to the trouble-
shooting section of this manual.
6. Do not exceed input rating stamped on nameplate or
manufacturer's recommended burner orifi ce pressure
for size orifi ce(s) used. Make certain that the primary
air supply to main burner is open and free of dust, dirt
and debris for complete, proper combustion.
A. Heating Mode Operation
a. Open all manual fuel supply valves. Check for gas
leaks using an approved leak detector. Check the gas
selector valve for proper gas.
b. When the selector switch is positioned to heat
and the thermostat is calling for heat, a set of green
lights will illuminate (power ON and thermostat ON).
There will be a 5 second delay, after which, the burner
fan motor will pre purge for 1 minute. After the burner
fan has pre purged, the igniter will spark and ignition
will occur. The main blower fan has a time delay of 30
seconds before operation. The thermostat will cycle
the heater ON or OFF based upon temperature set-
ting. LED will fl ash during cycle.
Note: When the thermostat cycles the heater off or
selector switch is switched to OFF, the main fan
motor will continue to run for an additional 90
seconds to cool down the heat exchanger.
B. Vent Mode Operation
When the selector switch is positioned to vent
only the fan motor light will illuminate. The fan motor will
start, but the burner motor will not, nor will ignition occur.
This feature is used typically when heat is not needed,
but air circulation is required. The heater will not cycle
on its thermostat setting. To discontinue the ventilation
feature, position the switch to midpoint O or heat
If you desire to use the ventilation feature, the
connection of the gas supply (i.e. hose and regulator) to
the fuel source is not needed.
C. Off O
