Installation of a POST PURGE KIT is REQUIRED for oil fired appliances for the purpose of venting combustion
products after the burner has shut down. This kit has an adjustable thermally activated sensing device that
continues to vent the flue system until the temperature drops below switch opening temperature.
(See Chart A)

MOUNTING THE POST PURGE SWITCH

1

Pierce a

⁄4" diameter hole into the vent pipe and mount the POST PURGE SWITCH on the vent pipe between

the barometric draft control and the appliance using the two (2) sheet metal screws. (See Figure 6)

NOTE: Wire the switch normally open. Refer to Unit Wiring Instructions.

POST PURGE TIME ADJUSTMENT PROCEDURE

Remove switch cover.1.
Using a screw driver, turn the adjustment screw counterclockwise to increase purge time and clockwise to 2.
