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.

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.
