FIRE HAZARD
Failure to follow this caution may result in intermittent unit
operation or performance satisfaction.
This furnace is equipped with a manual reset limit switch in
the burner box area. The switch will open and shut off power
to the gas valve if a flame rollout or overheating condition
occurs in the burner enclosure area. DO NOT bypass the
switch. Correct inadequate combustion-air supply, compo-
nent failure, or restricted flue gas passageway before resetting
the switch.

Condensate trap must be PRIMED or proper draining may not
occur. The condensate trap has internal chambers which can
ONLY be primed by pouring water into the inducer drain side
of condensate trap.
1. Remove upper inducer housing drain connection cap. (See
Fig. 50.)
2. Connect field-supplied 1/2-in. ID tube to upper inducer
housing drain connection.
3. Insert field-supplied funnel into tube.
4. Pour 1 quart of water into funnel/tube. Water should run
through inducer housing, overfill condensate trap, and flow
into open field drain. (See Fig. 51.)
5. Remove funnel and tube from inducer housing and replace
drain connection cap and clamp.
Step 3—Purge Gas Lines
After all connections have been made, purge the gas lines and
check for leaks.
