18. RECOMMENDED MAINTENANCE
Improper adjustment, alteration, service or maintenance can cause property damage,
injury or death. This heater must be installed and serviced only by a trained gas ser-
vice technician.
At least annually inspect the entire heater system, venting, and gas supply connections prior to
the heating season. Replace worn parts and repair deficiencies.
1. Periodically check the inlet air opening and the blower squirrel cage vanes, cleaning off
any lint or foreign matter. It is important that the flow of combustion and ventilation air
must not be obstructed.
2. Annually, prior to the heating season, lubricate
the blower motor assembly by introducing several
drops of oil to the top and bottom oil tubes located
on the left hand side of the motor.
3. Periodically inspect the vent and vent termination
to ensure no debris is blocking the vent, and that
the integrity and construction of the vent piping is
sound and no leakage is occurring.
4. Visually inspect the burner flame periodically to ensure proper performance. The flame is
visible through the sight glass assembly located on the bottom surface of the tube just
downstream of the burner. The flame should be substantially blue - the occasional yellow
fleck is normal. The flame should originate tight back to the burner cup face, and become
cone shaped as it travels away from the burner cup. If the flame becomes yellow/orange,
or if the flame is lifting away from the burner cup face, the burner requires cleaning or re-
pair that must be conducted by a qualified gas service technician.
5. On an on-going basis, ensure that the area around the heater is kept clear and free from
combustible materials, gasoline and other flammable liquids and vapors.
6. CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors
can cause improper and dangerous operation.
7. Verify proper operation after servicing.
