SECTION 10: MAINTENANCE 10.1 Pre-Season Maintenance

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.

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.
