SECTION 10: MAINTENANCE
10.1 Pre-Season Maintenance
For best performance, the following maintenance
procedures must be performed by a contractor quali-
fied in the installation and service of gas-fired heating
equipment before each heating season:
1. Due to high temperature, ensure that the
heater area is kept clear of clothing, furniture,
draperies or other combustible materials,
gasoline and other flamable vapors and liq-
uids. See Page 15, Section 4.6, the thermostat
wall tag or clearance to combustibles label on
heater.
2. Turn off gas and electrical supplies to the heater.
3. Check condition of burner. Carefully remove any
dust or debris from inside the 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 or dirt. After cleaning
as necessary, re-attach the flue pipe to the
heater.
7. Keep surfaces of burner, control compartment
and reflector clean by wiping with a dry cloth.
More frequent cleaning may be required due to
excessive dirt, dust, lint material, etc.
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 pressure switch will not close, resulting in a
no-heat situation.
WARNING
Turn off gas and electrical supplies before performing
service or maintenance.
Failure to follow these instructions can result in
death, injury or property damage.
