Prime Condensate Trap with Water
CARBON MONOXIDE POISONING HAZARD
Failure to follow these warnings could result in p ersonal injury
or death.
Failure to use a properly configured trap or NOT
water--priming trap before operating furnace may allow
positive pressure vent gases to enter the structure through drain
tube. Vent gases contain carbon monoxide which is tasteless
and odorless.

WARNING
UNIT OPERATION HAZARD
Failure to follow this caution may result in intermittent unit
operation or performance satisfaction.
Condensate trap must be PRIMED or proper draining may
not occur. The condensate trap has two internal chambers
which can ONLY be primed by pouring water into the
inducer drain side of condensate trap.
CAUTION
!
1. Remove upper and middle collector box drain plugs oppo-
site of the condensate trap. See Fig. 58.
2. Connect field-supplied 5/8-in. (16 mm) ID tube with at-
tached funnel to upper collector box drain connection. See
Fig. 58.
3. Pour one quart (liter) of water into funnel/tube. Water
should run through collector box, overfill condensate trap,
and flow into open field drain.
4. Remove funnel; replace collector box drain plug.
5. Connect field-supplied 5 /8-in. (16 mm) ID tube to middle
collector box drain port.
6. Pour one quart (liter) of water into funnel/tube. Water
should run through collector box, overfill condensate trap,
and flow into open field drain.
7. Remove funnel and tube from collector box and replace
collector box drain plug.

Purge Gas Lines
If not previously done, purge the lines after all connections have
been made and check for leaks.
FIRE OR EXPLOSION HAZARD
Failure to follow this warning could result in personal
injury, death, and/or property damage.
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. A fire or explosion may
result causing property damage, personal injury or loss of
life.

WARNING
Adjustments
FURNACE DAMAGE HAZARD
Failure to follow this caution could result in reduced furnace
life.
DO NOT push or force gas valve adjusting screw . This can
result in damage to the adjustment screw resulting in incorrect
manifold pressure, which can result in a no heat situation or
shorten the life of the heat exchangers.
