MAINTENANCE
PERIODIC SERVICE
NOTICE: The heater and vent system should be checked once a year by a qualified technician.
All Maintenance/Service information should be recorded accordingly on the Inspection Sheet provided in this manual.
Open all disconnect switches and disconnect all electrical and gas supplies and secure in that position before servicing unit. Failure to do so may result in personal injury or death from electrical shock.
Should maintenance be required, perform the following inspection and service routine:
1.Inspect the area near the unit to be sure that there is no combustible material located within the minimum clearance requirements listed in this manual.
Under no circumstances should combustible material be located within the clearances specified in this manual. Failure to provide proper clearance could result in personal injury or equipment damage from fire.
2.Turn off the manual gas valve and electrical power to the unit heater.
3.To clean or replace the main burners, remove burner cover. Remove top strip from above main burners. Lift burners up and pull away from manifold to remove.
4.With the burners removed, wire brush the inside surfaces of the heat exchanger.
5.Remove any dirt, dust, or other foreign matter from the burners using a wire brush and/or compressed air. Ensure that all parts are unobstructed. Inspect and clean the pilot burner if necessary.
6.Reassemble the unit heater by replacing all parts in reverse order.
7.Relight the pilot (see lighting instruction on the unit nameplate). Complete the appropriate unit startup procedure as given in the “Operation” section of this manual.
8.Check the burner adjustment.
9.Check all gas control valves and pipe connections for leaks.
10.Check the operation of the automatic gas valve by lowering the setting of the thermostat, stopping the operation of the gas duct furnace. The gas valve should close tightly, completely extinguishing the flame on the main burners.
11.Inspect and service motor/fan assembly. To maintain efficient air flow, inspect and clean the fan blades and guard to prevent buildup of foreign matter.
12.Check lubrication instructions on motor. If oiling is required, add 3 or 4 drops of electric motor oil as follows:
a.Light Duty - After 3 years or 25,000 hours of operation.
b.Average Duty - Annually after 3 years or 8,000 hours of operation.
c.Heavy Duty - Annually after 1 year or at least 1500 hours of operation.
Never over oil the motor or premature failure may occur!
14.Check and test the operational functions of all safety devices supplied with your unit.
