OPERATION
Operation of the Heater
CHILDREN AND ADULTS SHOULD BE ALERTED TO THE
HAZARDS OF HIGH SURFACE TEMPERATURES AND
SHOULD STAY AWAY TO AVOID BURNS OR CLOTHING
IGNITION.
YOUNG CHILDREN SHOULD BE CAREFULLY SUPERVISED
WHEN THEY ARE IN THE SAME SPACE AS THE HEATER.
CLOTHING OR OTHER FLAMMABLE MATERIALS SHOULD
NOT BE HUNG FROM THE HEATER, OR PLACED ON OR
NEAR THE HEATER.
ANY GUARD OR OTHER PROTECTIVE DEVICE REMOVED
FOR SERVICING THE HEATER MUST BE REPLACED PRIOR
TO OPERATING THE HEATER.
INSTALLATION AND REPAIR SHOULD BE DONE BY A
QUALIFIED SERVICE PERSON. THE HEATERS SHOULD
BE INSPECTED BEFORE USE AT LEAST ANNUALLY BY A
QUALIFIED SERVICE PERSON. MORE FREQUENT CLEANING
MAY BE REQUIRED AS NECESSARY. IT IS IMPERATIVE
THAT THE CONTROL COMPARTMENT, AIR PASSAGEWAYS
AND BURNER(S) OF THE HEATER ARE KEPT CLEAN.
1.
Turn the thermostat up. When the thermostat calls for
heat, the blower motor will energize.
2. When the motor approaches nominal running speed,
the air proving switch closes and activates the ignition
module which in turn initiates the 15 second long
purge.
3. The ignition module then energizes the spark igniter.
4. When sparking begins, the gas valve is energized.
5. If a flame is detected, the gas valve remains open.
When the call for heat is satisfied, and the system
control mechanism de-energizes, the burner line
voltage supply and the gas valve are turned off.
6. If no flame is detected, the gas valve is closed, and
a purge period begins. After the purge period, the
ignition module energizes the spark igniter and the
gas valve. If a flame is still not established, a third and
final purge/ignition sequence is begun. After three
failed attempts, the system control mechanism will lock
out for a period of one hour, or until the unit is reset.
Reset is accomplished by removing power from the
heater for at least five seconds.
7.
Periodically visually check of burner flame while unit is
in operation through sight glass in the side of unit.

MAINTENANCE
Pre-Season Maintenance
Heater area to be kept clear and free from combustible
materials, gasoline, and other flammable vapors and
liquids.
Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect the
appliance and replace any part of the control system and
any gas control which has been under water.
(CAUTION) Label all wires prior to disconnection when
servicing controls. Wiring errors can cause improper and
dangerous operation.
For best performance, the following maintenance
procedures should be performed by a qualified service
agency before each heating season:
1.
A qualified service agency should be contacted for
service other than routine maintenance.
2. Check condition of blower scroll and motor. Dirt and
dust may be blown out with compressed air, or a
vacuum cleaner may be used.
3. Check the condition of the burner. Carefully remove
any dust or debris from inside burner.
4. Inspect the igniter. Replace igniter if there is excessive
carbon residue, erosion of electrodes or other defects.
5. Check to see that the burner observation window is
clean and free of cracks or holes. Clean or replace as
required.
6. Check the flue pipe for soot, dirt, or obstructions. The
flow of combustion and ventilation air should not be
obstructed. After cleaning as necessary, re-attach the
flue pipe to the heater.
7.
Outside surfaces of heater reflector may be cleaned by
wiping with a damp cloth.
8. Check vent terminal and outside air inlet to see that
they have not become blocked during the non-heating
season If either pipe is restricted, the air switch won't
close, resulting in a non-heat situation.
9.
Verify proper operation after service.
