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, set the building
controller to call for heat. The heater will start.
1. Open all manual fuel supply valves and
check for gas leaks using approved leak
detectors.
2. Connect the electrical cord to an approved
electrical outlet.
3. Set the building controller to desired room
temperature.
4. This heater includes a control module for
purposes of controlling the timing of the
ignition process of the heater as well as
monitoring safety functions. The controller is
located within the control box.
On the ignition control is a red light emitting
diode (LED). The LED indicates the staus of
the heaters and is visible external of the control
box through the plastic window on the box.
A constant light from the LED indicates the
heater is functioning correctly. Any blinking
light pattern of the LED indicates a problem in
the operation of the heater.
Refer to the troubleshooting decal on the
heater for assistance in troubleshooting, or
refer to the troubleshooting fl ow charts within
this manual. Only qualifi ed and properly trained
personnel shall service or repair the heater.
HOT SURFACE IGNITION HEATERS
(Models AW060/100/250)
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 to ensure the air
proving switch is operational, and a normal
operational characteristic prior to ignition taking
place. After the motor has stopped, the ignitor
will heat up (approximately 17 seconds) . After
the ignitor has heated, the ignition control will
restart the fan motor, with ignition occuring
shortly after.
The ignition control will make up to three trials
for ignition. 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 passed, the
third and fi nal trial for ignition will occur. 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.
DIRECT SPARK IGNITION HEATERS
(Models AD060/100/250)
On a call for heat, the motor will start up and run for
fi ve (5) seconds to ensure the air proving switch is
operational. This pre-purge is a safety feature and
a normal operational characteristic prior to ignition
taking place. After fi ve seconds, with the motor still
running, the igniter will begin to spark with ignition
occuring shortly after.
The ignition control will make up to three trials for
ignition. Each trial for ignition will take approximately
10 seconds. The fi rst three trials for ignition will occur
within 40 seconds if ignition is not achieved. A 15
minute wait period will then begin after the third trial
for ignition has taken place. After the 15 minute time
span has elapsed, three more trials for ignition will
occur. 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.
REGARDLESS OF IGNITION TYPE: 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 ignition takes place.
Shut-Down Instructions
If the heater is to be shut down for cleaning, mainte-
nance or repair, follow steps 1 - 4. Otherwise, set the
building controller to off.
1. Close all manual fuel supply valves.
2. With the heater lit, allow heater to burn off excess
fuel in gas supply hose.
3. Set the building controller to off.
4. Disconnect the heater from the electrical supply.
