Operation & Maintenance

Sequence of Operation

1. Turnthethermostatup.Whenthethermostatcallsforheat,

2. WhenthemotorapproachesnominalrunningRPM,theair

provingswitchclosesandactivatestheignitionmodule.

3. Theignitionmodulethenenergizesthehotsurfaceigniterfor

atimedwarm-upperiod(approximately45to60seconds.)

4. Afterthewarm-upperiod,thegasvalveisenergized.
