USAGE INSTRUCTIONS
WARNING: The tank manifold/regulator assembly and gas hose assembly
must be visually inspected prior to each use of the heater. If there is evidence of
excessive abrasion or wear, or any hose is cut, it must be replaced prior to the
heater being put into operation.
WARNING: The heater must be located at least 10 feet from any propane gas
container. The heater’s discharge air shall not be directed toward any propane gas
container within 20 feet. Do not store propane in the space where the heater is to
be operated.
WARNING: The gas supply hose assembly must be protected from trac,
building materials and contact with hot surfaces both during use and while in
storage.
d. Slowly open all the gas supply manual valve(s) and allow pressure to equalize.
e. Check all pipe connections, hose connections, manual valves, ttings, and adapters
upstream of the heater’s electronic gas control valve for gas leaks using approved
gas leak detectors. In the event a gas leak is detected, check the components
involved for cleanliness and further tighten as necessary to stop the leak. Do not
proceed until all leaks are eliminated.
WARNING: All gas leaks detected must be repaired before heater is placed
into service.
Electrical Connection
a. Plug the Interconnect Cable into the fresh air fan module and the heater.
b. Plug the electrical power cord into the Fresh Air Fan Module and Heater. Plug both
into a properly grounded 115V 60Hz outlet (15A or greater).
WARNING: This appliance is equipped with a three-prong (grounding) plug
for your protection against shock hazard and should be plugged directly into a
properly grounded three-prong receptacle.

USAGE INSTRUCTIONS
Heater Start-Up
a. Turn the fresh air fan module’s POWER switch to the “ON” position. The fresh air
fans will begin to run.
b. Turn the heater POWER switch to the “ON” position and the circulating fans will
begin to run. The CO monitor will begin its initialization cycle and the alarm will
sound for several minutes until the system is operational.
c. Press the RESET button to enable the burner ignition system. The yellow Reset
Light and Low Gas Pressure Light will go o.
d. Turn the BURNER ENABLE switch to the “ON” positon to allow the burner to re.
e. Heater will attempt ignition after a 30 second pre-purge cycle.
NOTE: It is normal for air to be trapped in the gas hose upon each initial startup.
The heater may require more than one trial for ignition before air is nally purged
from line and ignition takes place.
f. Adjust the digital operating thermostat to the desired room temperature using the
“up” and “down” arrows. See detailed thermostat operating instructions below.
12
i. Press and release SET. The current value of the temperature set point SP1 is
displayed. SP1 and led OUT1 blink.
ii. Press UP or DOWN to increase or decrease the value.
iii. Press SET to conrm the new value. The current value of temperature set point
SP2 is displayed. SP2 and led OUT2 blink.
iv. Press UP or DOWN to increase or decrease the value. Press SET to conrm the
new value and exit.
NOTE: Only SP1 is utilized at this time. SP1 may only be set between 120 and 140
degrees F. OUT1 led energizes when thermostat SP1 is satised. The on/o set
point dierential is 2 degrees F.

USAGE INSTRUCTIONS
Heater Shut-Down
a. Close the LP cylinder valve(s) and allow the heater to burn o any fuel gas
remaining in the gas supply hose.
b. Turn the BURNER ENABLE switch to the “OFF” position.
c. Allow the heater circulating fan to continue to run for several minutes to cool the
heater.
d. Turn the heater POWER switch to the “OFF” position.
e. Close the remaining manual shut-o valve(s) and disconnect the gas supply piping
from the heater’s external connection. Plug all gas supply inlets to prevent the
entry of debris.
f. Turn the fresh air fan module’s POWER switch to the “OFF” position.
g. Unplug the power cord from the wall outlet and both the Fresh Air fan Module and
Heater.
h. Unplug the Interconnect Cable Fresh Air fan Module and Heater. Remove fresh air
fan module return door or window to its normal position.
i. When the heater is stored indoors, the connection between the propane supply
cylinder(s) and the heater must be disconnected and the cylinder(s) removed
from the heater and stored in accordance with the Standard for the Storage and
Handling of Liqueed Petroleum Gases, ANSI/NFPA 58 or the Natural Gas and
Propane Installation Code, CSA B149.1, as applicable.
WARNING: The gas supply hose assembly must be protected from trac,
building materials and contact with hot surfaces both during use and while in
storage.

Heater Shut-Down

1. Power on the Fresh Air Fan Module. Fresh air fans run.
2. Power on the heater unit. Circulating fan runs.
3. Press the RESET button and turn on BURNER ENABLE switch on the heater unit.
4. Thermostat closes on call for heat providing 24 VAC to Ignition Control.
5. Draft Inducer is energized (@ line voltage).
6. Air Switch closes initiating pre-purge period.
7. At end of pre-purge period, Spark and Gas Valve are energized for an ignition trial
period.
8. Burners ignite and carryover.
9. Flame is detected by ame sensor and control operates in steady state heating
condition.
10.Burners continue to re until the thermostat is satised.
11.Thermostat opens interrupting power to control and closes fuel valve to stop ring.
12.The unit enters its post-purge period.
13.If ignition is not achieved within the trial period, the gas valve is shut o; the inducer
continues to run for a 30 second inter-purge period. Additional ignition trials follow
the specied sequence. If all trials (3) for ignition have occurred without proper
ignition and ame detection, the control locks out. See ash codes on Page 20.
14.Control may be brought out of lockout by cycling the BURNER ENABLE switch or
shutting o power for a minimum of 5 seconds.
15.If ame is lost once it has been established, the control will shut o the gas
supply within 2.0 seconds and enter the inter-purge period. Control will allow a
predetermined number of ame losses before lockout. (To restart, refer to step 13)
16.If ame sensor indicates presence of ame during purge period, when no ame
should be present, the inducer will remain energized, but the gas valve will remain
o until the cause of the “false ame” is removed.
