FIRE OR EXPLOSION HAZARD
Failure to follow this warning could result in
personal injury and/or death.
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.
5. Carefully remove the manifold assembly.
6. Remove the orifices from the manifold and replace them
with proper sized orifices. See Figure 18.
7. Tighten orifices so they are seated and gas tight. See
Figure 18.
8. Reassemble all parts in reverse order as removed. Be sure
to engage the main burner orifices in the proper openings in
the burners.
9. After reassembling, turn gas on and check all joints for gas
leaks using a soapy solution. All leaks must be repaired im-
mediately.

RISQUE D'EXPLOSION ET D'INCENDIE
Le fait de ne pas suivre cet avertissement pourrait
entrainer des dommages corporels et / ou la mort.
Ne jamais examiner pour les fuites de gaz avec une
flamme vive. Utilisez plut6t un savon fait
specifiquement pour la detection des fuites de gaz
)our verifier tous les connections.

The furnace and the equipment shut off valve must be dis-
connected from the gas supply piping system during any
pressure testing of that system at test pressures in excess
of 1/2" PSIG (3.5 Pa). Close the manual shut-off valve be-
fore testing at such pressures.
The furnace must be isolated from the gas supply system
by closing the equipment shut off valve during any pressure
testing of the gas supply system at test pressure equal to or
less than 1/2" PSI (3.5 Pa).
When installation is complete, test all pipe connections for
leaks with the gas pressure less than
1/2"
PSlG (3.5 Pa) to
the gas valve.
Apply a commercial soap solution to all joints to test for
leaks. Correct any leaks indicated by bubbles.
Correct even the smallest leak at once.
Check for leaks at gas valve and orifice connections to the
burner manifold along with the pilot tube connections to the
valve and pilot assembly while the furnace is operating.
ELECTRICAL SHOCK HAZARD
Failure to turn off power could result in personal
injury or death.
Turn OFF electrical power at fuse box or service
panel before making any electrical connections
and ensure a proper ground connection is made
before connecting line voltage.
PowerSupplyWiring
The furnace MUST be electrically wired and grounded in accor-
dance with local codes, or in the absence of local codes, with the
National Electrical Code (NEC), NFPA 70-2008 in the U.S., or the
Canadian Electrical Code (CEC), CSA C22.1 in Canada.
The power supply to the furnace connections must be between
104 VAC and 127 VAC during furnace operation for acceptable
performance.
Field wiring connections must be made inside the furnace connec-
tion box. A suitable strain relief should be used at the point the
wires exit the furnace casing.
Copper conductors shall be used. Line voltage wires should
conform to temperature limitation of 35 ° C rise. Wire and circuit
breaker sizing shall be based on the ampacity of the furnace elec-
trical components plus the amps for all installed accessories (1.0
amps total for EAC and HUM). Ampacity can be determined by us-
ing the NEC or CEC.
NOTE: Furnace will not have normal operation is line polarity is
reversed. Check ALL field and control connections prior to opera-
tion.
Furnace must be installed so the electrical components are pro-
tected from water and connected to its own separate circuit.
Junction Box (J- Box) Relocation
The J-Box is installed in the burner compartment on left side of
casing. An alternate J-Box location on right side can be used.
1. Remove and save two screws holding J-Box to casing.
