Burner Controller Module (BCM)

The burner controller module provides effective burner flame safeguard control through adjustable purge

and trial-for-ignition timing. The BCM insures that all dryer safety switch circuits are dosed, delays
ignition to allow the combustion chamber to vent, and insures that a healthy pilot flame is established
before opening the main gas valves. Five (5) LED's on the cover of the BCM allow for easy trouble
shooting. Dip switches on the back of the module allow for easy programming.

• Dip Switch Selections

Loosen the two (2) screws on the burner control module cover and pull the module cover off its base. The
dip switches are on the back of the cover.

Switch#! Recycling Mode

With this switch in the "on" position, the burner will recyde the ignition sequence once during each
drying cycle after a burner fan air switch or main flame failure, but only if the failure occurs more than
35 seconds after ignition. If this switch is "off," the burner will lock out at once.
