HE-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL ation of the heating system, service and annual inspections must be done by a contractor qualified in the installation and service of gas-fired heating equipment. Turn off gas and electric supplies before performing service or maintenance. Allow heater to cool before servicing. Before every heating season, a contractor qualified in the installation and service of gas-fired heating equipment must perform a thorough safety inspection of the heater.
SECTION 11: OPERATION AND MAINTENANCE Reflector Support Straps Tubes Verify that the reflector support straps are securely clamped to tube and reflector. See Page 24, Step 6.6.1. Verify tight and loose screws at reflector overlaps. Make sure there are no cracks. Make sure tubes are connected and suspended securely. See Page 15, Section 6. Make sure there is no sagging, bending or distortion. Clean any debris from top of tubes or replace as required. Check the inside of the firing tube with a flashlight.
