  • Page 41: Lighting And Shutdown Instructions

    18.0) LIGHTING AND SHUTDOWN INSTRUCTIONS 1) Turn on the gas and electrical supply. Rotate the gas valve knob counter-clockwise 2) Set the thermostat to call for heat. The blower motor will energize. 3) Ignition should occur after the 15-second pre-purge. 4) If the burner fails to light, or flame is not detected during the first trial for ignition (a period of approximately 15 seconds) the gas valve is de-energized and the control goes through an inter-purge delay of approximately 60 seconds before another ignition attempt.

  • Page 42: Burner Component Location

    Note : When the PTS / PTU is operated by a thermostat interrupting the line voltage (120V) to the heater then the post purge function is disabled. If the flame is not sensed during sequence T3 then the burner will automatically begin re-ignition sequence T2. The ignition sequence will be repeated three times with a 60 second inter-purge.

  • Page 43: Cleaning And Annual Maintenance

    21.0) CLEANING AND MAINTENANCE This heater must be cleaned and serviced annually by a qualified contractor before the start of each heating season and at any time excessive accumulation of dust and dirt is observed. Maximum heating efficiency and clean combustion will be maintained by keeping the heater clean.

    IGNITION MODULE DIAGNOSTICS Flame Fault If at any time the main valve fails to close completely and maintains a flame, the full time flame sense circuit will detect it and energize the combustion blower. Should the main valve later close completely removing the flame signal, the combustion blower will power off following the post purge period.
