16. SERVICE GUIDE
Conduct a maintenance inspection of a luminous heater at least annually, prior to the heating
season.
WARNING
Procedure:
1. Inspect the exhaust fan and all ancillary devices for proper operation and test for leaks at all gas
supply connections. Replace worn parts and repair deficiencies.
2. Inspect the integrity of the heater and reflectors. Repair or replace any defective parts. Clean accu-
mulated foreign matter from the reflectors and heater body.
3. During operation:
Visually inspect the ceramic burner tiles for cracks
A 'bright' line on the tile surface indicates a crack in the tile
Replace any cracked tile and seating gasket
A cracked tile is typically the result of physical impact – inspect the burner body for any
additional damage
Visually inspect the ceramic burner tiles for blockage by accumulated dust or foreign material
A dark spot on the tile surface indicates blockage of the tile.
Use low pressure air (less than 20 psig) directed at the tile surface - Avoid directing air
stream at the gasket material between tile and heater body.
4. Inspect the venturi tube:
Remove any accumulated dust or foreign matter - use low pressure air (less than 20 psig)
directed at the venturi. It is important that the flow of combustion air through the venturi not
be obstructed.
5. Check the gas supply pressure at the inlet to the gas valve (1/8" NPT tap):
Natural Gas: minimum 6.0" w.c. and maximum 14.0" w.c.
LPG: minimum 11.0" w.c. and maximum 14.0" w.c.
Remedy gas supply condition outside of these specifications.
6. Check the gas supply pressure from the gas valve to the heater manifold (1/8" NPT tap):
Natural Gas: 5.0" w.c.
LPG: 10" w.c.
Remedy manifold pressure condition outside of this specification by adjusting the pressure
spring on the gas valve
Ensure that the gas valve is operating properly and that no particulate matter is foul-
ing the seating of the valve and allowing gas leakage - replace valve if necessary.
7. Inspect operation of the electronic ignition system:
Refer to I&O Manual trouble shooting guide and sections relating to the Spark Ignition and
Flame Sensing.
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 service technician.
