USAGE INSTRUCTIONS
WARNING: Fresh air fan module must be installed to supply a continuous stream of
fresh ventilation air into the area being heated at all times during heater operation. Failure to
comply can result in death or serious bodily injury from hazards of asphyxiation or carbon
monoxide poisoning.

OSHA 29 CFR 1926.154, Safety Requirements for Temporary and Portable Space Heating Devices
and Equipment, ANSI A10.10, National Fuel Gas Code, ANSI Z223.1/NFPA 54, Liquefied Petroleum
Gas Code, NFPA 58 or the Natural Gas and Propane Installation Code, CAN B149.1, as applicable.
Gas Connection
a. Ensure all manual shut-o valves on the gas hose and LP tank manifold are in the closed
position. Verify the connections of all the gas fittings are tight.
b. A minimum of two (2) 20 lb LP cylinders manifolded together, or one (1) 100 lb LP tank is
required to operate heater. Storage, handling and use of propane must be in accordance with
all local codes and ordinances, as well as NFPA 58 and OSHA regulations.
WARNING: Supply cylinders must be designed, fabricated, tested and marked in
accordance with regulations of the U.S. Department of Transportation, Canadian Transport
Commission or the Interstate Commerce Commission, and must be arranged to provide for
vapor withdrawal from the operating cylinder(s).
WARNING: Connection to Liquid Propane gas (LP) cylinder(s) must conform with
local codes or, in their absence, with the Standard for the Storage and Handling of Liquefied
Petroleum Gases, ANSI/NFPA 58 or the Natural Gas and Propane Installation Code, CSA
B149.1, as applicable.
c. Connect the LP cylinder(s) to the provided tank manifold/regulator assembly and connect the
provided gas hose assembly between the regulator and the heater gas train by utilizing the
supplied ½” quick connect fittings.
8
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 trac, 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, fittings, 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 two interface cables into the fresh air fan module and the heater.
b. Plug the electrical power cord into the fresh air fan module and then into a properly grounded

MAINTENANCE INSTRUCTIONS
An annual inspection of the heater by qualified service personnel is recommended to check for
proper operation and to look for damage or degradation of any component. Any damaged or
deteriorated parts should be replaced before the unit is put back into service.
1. Turn o all electrical power before inspection and servicing.
2. Check Heat Exchanger for cracks and blockage.
3. Check and clean burners and carryover from dirt, rust and blockage by insects.
4. Check venting system for blockage by debris, including debris from animals and insects.
5. Check the piping for leaks.
6. Check and clean fan blades and fan guards from dirt, dust and blockage.
16
TROUBLESHOOTING
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 flame sensor and control operates in steady state heating condition.
10. Burners continue to fire until the thermostat is satisfied.
11. Thermostat opens interrupting power to control and closes fuel valve to stop firing.
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
specified sequence. If all trials (3) for ignition have occurred without proper ignition and
flame detection, the control locks out. See flash codes below.
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 flame 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 flame losses before lockout. (To restart, refer to Item 13)
16. If flame sensor indicates presence of flame during purge period, when no flame should be
present, the inducer will remain energized, but the gas valve will remain o until the cause
of the “false flame” is removed.
