Manual

Follow steps 1 - 6 on initial start-up after heater installation
by a qualified 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 and L.B.White SmartBox
™
to same 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
moniotoring safety functions. The HSI controller is
located within the control box.
On the HSI 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 flow charts within this manual. Only .
Only 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 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.
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 ignition control will make up to three trials for
ignition. Each trial for ignition will take approximately
20 seconds. The first 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 final trial for
ignition will occur. 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.
If the heater is to be shut down for cleaning, maintenance 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 and SmartBox
™
to off.
4. Disconnect the heater from the electrical supply.
