SEQUENCE OF OPERATION
On call for heat, the D-2 Power Vent fan (and appliance pump) start. When the flow switch
circuits close, the ignition system consisting of an electronic spark module, pilot gas system and
flame sensor, are energized. When draft proving switch closes and all safety circuits are
proven, the automatic main gas valves will open and the heater will operate. When the
operating limit circuit is satisfied, the heater will shut down.
