Condensate Trap Heat Tape
3. Use wire ties to secure heat tape in place. Wire ties can be
positioned in notches of condensate trap sides.
(See Fig. 45.)
4. Wrap field drain pipe with remaining heat tape,
approximately 1 wrap per ft.
5. When using field-supplied heat tape, follow heat tape
manufacturer’s
instructions
for
all
other
installation guidelines.
START-UP, ADJUSTMENTS, AND
SAFETY CHECK
Step 1—General
1. Furnace must have a 115-v power supply properly
connected and grounded.
NOTE
:
Proper polarity and proper grounding must be
maintained for 115-v wiring. If polarity is incorrect, controlled
LED status indicator will flash rapidly and furnace will
not operate.
2. Thermostat wire connections at terminals R, W, G, and
Y/Y2 must be made at 24-v terminal block on
furnace control.
3. Natural gas service pressure must not exceed 0.5 psig
(14-in. wc), and be no less than 0.16 psig (4.5-in. wc).
4. Blower access panel must be in place to complete 115-v
electrical circuit to furnace.
UNIT MAY NOT OPERATE
Failure to follow this caution may result in intermittent
unit operation.
These furnaces are equipped with a manual reset limit switch
in burner box. This switch will open and shut off power to gas
valve if an overheat condition (flame rollout) occurs in burner
enclosure. Correct inadequate combustion-air supply or
improper venting condition and reset switch. DO NOT jumper
this switch.
CAUTION
!
Before operating furnace, check flame roll-out manual reset
switch for continuity. If necessary, press button to reset switch.
Step 2—Prime Condensate Trap With Water
UNIT MAY NOT OPERATE
Failure to follow this caution may result in intermittent
unit operation.
Condensate trap must be PRIMED or proper draining may not
occur. The condensate trap has 2 internal chambers which can
ONLY be primed by pouring water into the inducer drain side
of condensate trap.
CAUTION
!
1. Remove upper inducer housing drain connection cap.
(See Fig. 46.)
2. Connect field-supplied 1/2-in. (13 mm) 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. 47.)
5. Remove funnel and tube from inducer housing and replace
drain connection cap and clamp.
Step 3—Purge Gas Lines
If not previously done, purge lines after all connections have been
made and check for leaks.

FIRE AND EXPLOSION HAZARD
Failure to follow this warning could result in property damage,
personal injury, or death.
Never purge a gas line into a combustion chamber. Never test
for gas leaks with an open flame. Use a commercially
available soap solution made specifically for the detection of
leaks to check all connections.
