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 direct ignition control
module for purposes of controlling the tim-
ing of the ignition process of the heater as
well as monitoring of the safety functions.
The module is contained within the control
enclosure.
On the 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
Owner's Manual • Guardian
ON
access panel at the fan motor end of the heater for
assistance 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. This pre-purge is a safety feature
and normal operational characteristic prior to
ignition taking place. After fi ve seconds, the igniter
should spark with ignition occurring.
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 ignition control will make up to three trials
for ignition. Each trial takes approximately ten
(10) seconds. The fi rst three trials occur within 30
seconds if ignition is not achieved. A 15 minute wait
period will then begin after the third trial has taken
place. After the 15 minute time span has elapsed,
the heater will then automatically restart with three
more trials occurring. If ignition still does not occur,
the system will "lock out" and a three time fl ash
code will be indicated by the control modules 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.
