When lit, these monitoring lights indicate normal conditions for power on inlet air and flue back pressures and gas valve on. Three system monitoring lights indicate normal burner operation.

This is followed by a 35-second trial for ignition during which a spark is developed at the ignition module and the gas valve is opened to the first step of its two-stage operation. When adequate inlet air and flue back pressure are present, the ignition detection control is energized and institutes a 15-second pre-purge cycle. ![]() This heater comes in three different colors of white, silver, and black, and each of them is capable of three heat settings between 500W and 1500W of power.

When the thermostat calls for heat, power is applied to the blower motor. Air and gas are thoroughly mixed in a spiral motion by the burner core assembly and are then ignited by a direct spark at the ignition module.īurner operation is monitored and controlled by an ignition detection control. Gas is then regulated by two orifices, an easily accessible subsidiary orifice sized for the appropriate length and BTUH rating of the burner, and a fixed main orifice. ![]()
