START-UP, ADJUSTMENTS AND SAFETY CHECK
Step l--General
1. Furnace mast have a 115-v power supply properly connected
and grounded. Proper polarity must be maintained fbr con'ect
operation.
NOTE: Proper polarity must be maintained for l15-v wiring. If
polarity is incorrect, ft/rnace control fault indicator light will flash
rapidly and furnace will not operate.
2. Them_ostat wire connections at terminals R, W, G, and Y
must be made at 24-v terminal block on thmace control center.
3. Natural gas service pressure must not exceed 0.5 psig (14oin.
we), but must be no tess than 0.16 psig (4.5-in. wc).
4. Blower access panel must be in place to complete l15-v
electrical circuit to furnace.
FIRE HAZARD
Failure to follow this caution may result in intermittent unit
operation.
These thrnaces are equipped with a manual reset limit switch
in burner box. This switch will open and shut offpower to gas
control vah'e if an overheat condition (flame rollout) occurs
in burner enclosure. Correct inadequate combustion-air sup°
ply or improper venting condition and reset switch DO NOT
jumper this switch
Befbre operating f_/mace, check flame rollout manual reset switch
for continuity. If necessa_, 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 charnbers 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. 44)
2, (onnect field-supplied 1i2oin ID robe to upper inducer
housing &ain connection,

3 Insert field-supplied fhnnel into tube
4. Pour 1 quart of water into funnel/robe. Water should run
through inducer housing, overfill condensate tIap, and flow
into open field drain. (See Fig. 45.)
5. Remove funnel and robe fiom inducer housing and replace
drain connection cap and clamp.
