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 both rollout switches.
6. Connect the wires to the flame sensor and hot surface ig-
niter.
7. Connect the connector harness to gas valve.
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.

FIRE, EXPLOSION, ELECTRICAL SHOCK
HAZARD
Failure to follow this warning could result in personal
iniury, death or property damage.
Gas supply MUST be shut off before disconnecting
electrical power and proceeding with conversion.
ELECTRICAL SHOCK, FIRE OR EXPLOSION
HAZARD
Failure to follow this warning could result in personal
iniury, death or property damage.
Before installing, modifying, or servicing system, main
electrical disconnect switch must be in the OFF position and
install a lockout tag. There may be more than one
disconnect switch. Lock out and tag switch with a suitable
warning label. Verify proper operation after servicing.
NOTE: Use propane-gas-resistant pipe dope on all connections
to prevent gas leaks. DO NOT use Teflon tape.
1. Be sure main gas and electric supplies to furnace are off.
2. Remove l/8-in. (3 mm) pipe plug from inlet pressure tap
on gas valve. DO NOT DISCARD l/8-in. (3 mm) PLUG.
3. Apply pipe dope sparingly to one end of 1/8-in. (3 mm) x
2--in. (51 mm) brass nipple (provided in kit) and install
the doped end in 1/8-in. (3 mm) tapped opening in gas
valve inlet pressure-tap. Tighten fitting with a small
wrench.
4. Apply pipe dope sparingly to opposite end of the l/8-in.
(3 mm) x 2--in. (51 mm) brass coupling (provided in kit).
Install the female end of the female x female x male tee on
the brass coupling.
5. Tighten tee finger tight. Use a small open-end wrench for
final tightening. The male end of the tee should be facing
you.
6. Apply pipe dope sparingly to male end of brass tee.
7. Install propane low gas pressure switch (provided in kit)
on male end of the female x female x male tee.
8. Tighten switch finger tight.
9. Use a small open-end wrench on base of pressure switch
for final tightening. The contacts of the LGPS should be
pointing toward the inducer motor when complete.
10. The remaining opening on the brass street tee is the new
gas valve inlet pressure tap.
11. Install manometer fitting to the open end of the brass street
tee. Or if installation is to be completed later, apply pipe
dope to inlet pressure plug from gas valve and install in
open end of brass street tee.
12. Check all fittings for leaks after gas supply has been
turned on.
