: Use pipe dope approved for use with Propane gas.
2. Apply pipe dope sparingly to the 1/8--in. NPT pipe plug
(provided in kit) and install in the 1/8--in. tapped inlet--

turned on.
FIRE AND 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. A fire or
explosion may result causing property damage, personal
injury or loss of life.

WARNING
RISQUE D’EXPLOSION ET D’INCENDIE
Le fait de ne pas suivre cet avertissement pourrait entraîner des
dommages corporels et / ou la mort.
Ne jamais examiner pour les fuites de gaz avec une flamme
vive. Utilisez plutôt un savon fait specifiquement pour la
détection des fuites de gaz pour verifier tous les connections.
Un incendie ou une explosion peut entrainer des dommages
matériels, des blessures ou la mort.

AVERTISSEMENT
Casings Wider Than 14 3/16-in. (360 mm) /Vent Does Not
Pass Between Inducer and Burner Assembly
If the vent pipe does not pass between the inducer and burner
assembly, or the furnace is wider than a 14 3/16-in. (360 mm)
wide casing, the switch may have been installed as follows. (See
Fig 11.)

Assembly
1. Remove low gas pressure switch, brass street 90
_
elbow,
brass Hex nipple, brass Tee and brass nipple from the gas
valve inlet pressure tap. (See Fig 11.)
NOTE
: Use pipe dope approved for use with Propane gas.
2. Apply pipe dope sparingly to the 1/8--in. NPT pipe plug
(provided in kit) and install in the 1/8--in. tapped inlet--
pressure tap opening in the gas valve. DO NOT over--
tighten. Check for gas leaks after gas supply has been
turned on.
INSTALL MANIFOLD
1. Align the orifices in the manifold assembly with the sup-
port rings on the end of the burner.
2. Insert the orifices in the support rings of the burners. Man-
ifold mounting tabs should fit flush against the burner box
NOTE
: If manifold does not fit flush against the burner box, the
burners are not fully seated forward. Remove the manifold and
check burner positioning in the burner box assembly.
3. Attach the green/yellow wire and ground terminal to one
of the manifold mounting screws.
4. Install the remaining manifold mounting screws.
5. Connect the wires to the flame sensor and hot surface ig-
niter.
6. Connect the connector harness to gas valve.
7. Rewire unit low pressure switch (LPS) as follows:
a. Trace one of the orange wires previously disconnected
from the LGPS back to the NO terminals of the LPS.
b. Trace the other orange wire previously disconnected
from the LGPS back to its splice connection with the yel-
low wire of the furnace wire harness. Disconnect and dis-
card this orange wire and the splice connection.
c. Connect the yellow wire of the furnace wire harness (see
“b” above) to the NO terminal of the LPS.
d. Refer to the furnace wiring diagram to ensure proper loca-
tion of wires.
NOTE
: Use only Propane-resistant pipe dope. DO NOT use
Teflon tape.
8. Insert the gas pipe through the grommet in the casing. Ap-
ply a thin layer of pipe dope to the threads of the pipe and
thread the pipe into the gas valve.
NOTE
: Use a back-up wrench on the gas valve to prevent the
valve from rotating on the manifold or damaging the mounting to
the burner box.
9. With a back-up wrench on the inlet boss of the gas valve,
finish tightening the gas pipe to the gas valve.
10. Turn gas on at electric switch on gas valve.
