Start-Up And Shut-Down - L.B. White AW060 Installation And Service Manual

Start-U U p I I nstructions
Follow steps 1 - 6 on initial start-up after heater installation
by a qualified 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
incorporated into the valve assembly. The control
valve may be located within an enclosure.
necessary, remove the metal cover and make sure the
indicator on the control valve's knob is turned to the
"on" position. Reinstall the metal cover.

2. Connect the electrical cord to an approved electrical
outlet.
3. Set the thermostat (if supplied) 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
contained 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
Shut-D D own I I nstructions
If the heater is to be shut down for cleaning, maintenance or
repair, follow steps 1 - 5. Otherwise, simply turn thermostat
to "off" or "no heat" for standard shut down.
1. Close all manual fuel supply valves.

eye. A constant light from the LED is an indicator that
the heater is functioning correctly. Any flash 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 assistance in troubleshooting.
qualified and properly trained personnel shall service
or repair the heater.
5. On a call for heat, the motor will start up and run for

five (5) seconds and then stop. This pre-purge is a
safety feature and a normal operational characteristic
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 finally purged from the line and
ignition takes place.
6. The current design HSI control module (part #120-
09298) will make up to three trials for ignition. Each
trial for ignition will take approximately 20 seconds. 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 final trial
for ignition will take place. If ignition is not achieved
at this final trial, the system will lock out, and a "three
flash" pattern will be indicated by the LED.
The earlier design ignition control module (part #120-
08117) will make 3 trials for ignition in approximately
one minute. If ignition is not achieved after the third
trial, the ignition control will lock out immediately. A
three-time flash pattern will be given.
2. With the heater lit, allow heater to burn off remaining
fuel in gas supply hose.
3. Turn the indicator on the gas control to "off".
4. Turn thermostat to "off" or "no heat" position.
5. Disconnect the heater from the electrical supply.
