F97CMN and G97CMN: Installation, Start-up, Operating and Service and Maintenance Instructions
Prime Condensate Trap with Water
WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow these warnings could result in personal 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.
CAUTION
!
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.
1. Remove upper and middle collector box drain plugs opposite of the
condensate trap. See Fig. 59.

(Appearance May Vary)
2. Connect field-supplied 5/8-in. (16 mm) ID tube with attached
funnel to upper collector box drain connection, see
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.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
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.
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.
FURNACE DAMAGE HAZARD
Failure to follow this caution may result in reduced furnace life.
DO NOT redrill orifices. Improper drilling (burrs, out-of-round holes,
etc.) can cause excessive burner noise and misdirection of burner
flames. This can result in flame impingement of heat exchangers,
causing failures, see
A11392
Fig. 59.
For proper operation and long term reliability, the Furnace input rate
must be within +/-2 percent of input rate on furnace rating plate or as
adjusted for altitude.
The gas input rate on rating plate is for installations at altitudes up to
2000 ft. (609.6M).
