Start-Up Instructions

Follow steps 1 - 6 on initial start-up after
heater installation by a qualifi ed gas heater
service person. For normal start-up, simply
turn thermostat above room temperature. The
heater will start.
1. Open all manual fuel supply valves and
check for gas leaks using approved leak
detectors. The gas control valve on the
heater has a manual shut-off feature incor-
porated into the valve assembly and may
be located under a metal cover. Remove
the metal cover (if applicable) and make
sure the indicator on the valve is turned to
the ON position. Replace the metal cover.

2. Connect the electrical cord to an approved
electrical outlet.
3. Set the thermostat to desired room
temperature.
4. This heater includes a hot surface ignition
(HSI) control module for purposes of
controlling the timing of the ignition process
of the heater as well as monitoring of the
safety functions. The HSI module is con-
tained within the control enclosure.
On the HSI module is a red light emitting
diode (LED). This LED indicates the status
of the heater. The LED is visible external
of the control enclosure through the plastic
eye.
A constant light from the LED is an indicator
that the heater is functioning correctly. Any
fl ash pattern by the LED is indicative that
there is a problem in the operation of the
heater.

Refer to the troubleshooting decal on the access
panel at the fan motor end of the heater for as-
sistance in troubleshooting. Only qualifi ed and
properly trained personnel shall service or repair
the heater.
5. On a call for heat, the motor will start up and run for
fi ve (5) seconds and then stop. This pre-purge is a
safety feature and a normal operational character-
istic prior to ignition taking place. After the motor
has stopped, the igniter will heat up (approximately
17 seconds). After igniter warm up time has been
achieved, the motor will start again and shortly
thereafter ignition will occur.
NOTE: It is normal for air to be trapped in the gas
hose on new installations. The heater may
attempt more than one trial for ignition before
the air is fi nally purged from the line and igni-
tion takes place.
6. The HSI control will make up to three trials for igni-
tion. Each trial for ignition will take approximately
20 seconds. The fi rst two trials for ignition will occur
within 40 seconds if ignition is not achieved. A 15
minute wait period will then begin after the second
trial for ignition has taken place. After the 15 minute
time span has elapsed, the third and fi nal trial for
ignition will take place. If ignition is not achieved at
this fi nal trial, the system will lock out, and a three
fl ash pattern will be indicated by the LED.
Shut-Down Instructions
If the heater is to be shut-down for cleaning,
maintenance or repair, follow steps 1-4. Other-
wise, simply turn thermostat to OFF or no heat
for standard shut down.
1. Close all manual fuel supply valves.
2. With the heater lit, allow heater to burn off
excess fuel in gas supply hose.
3. Position thermostat to OFF or no
heat position.
4. Disconnect the heater from the
electrical supply.
