Variable Heat Output; Start-Up Instructions - L.B.White Guardian AD/AW060 Manual Del Usuario E Instrucciones

Variable Heat Output

1. Some models of propane (LP) gas or natural gas
heaters have a throttle valve for varying heat output
located between the gas control valve and gas
manifold assemblies. See Fig. 6. THIS IS NOT A
MANUAL GAS SHUT OFF VALVE.
2. The throttle valve can be adjusted to deliver either
minimum heat or maximum heat. When the throttle
valve handle is parallel to the gas flow, the valve is
completely open to deliver maximum heat output.
The throttle valve may be adjusted to minimum heat
output by turning the handle 90° to gas flow or any
position between maximum and minimum settings.

2. Connect the electrical cord to an approved electrical
outlet.
3. Set the thermostat to desired room temperature.
4. This heater includes an ignition control module for
purposes of controlling the timing of the ignition
process of the heater as well as monitoring of the
safety functions. The control module is contained
within the control enclosure.
On the control 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 flash pattern by
the LED is indicative that there is a problem in the
operation of the heater.
Refer to the troubleshooting decal on of the heater
for assistance in troubleshooting. 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. This pre-purge is a safety feature
and a normal operational characteristic prior to
ignition taking place.

6. The motor will stop. 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 there after ignition
will occur.
