Fig. 11 - Installing Propane Jumper

NOTE: The Propane jumper for the modulating gas valve is

very small. Needle-nose pliers are required to insert the jumper

operate properly on propane.

1. Locate the round "NAT. GAS" sticker on the top of the

gas valve.

2. Peel the sticker off and discard.

3. Note the small square opening in the top of the gas valve.

4. Note the 2 jumper pins inside the modulating gas valve.

5. Remove the small black plastic propane jumper from the

envelope.

6. Use needle-nosed pliers to hold the jumper by the tab on

the end.

7. Insert the jumper on the pins inside the gas valve.

8. Cover the opening in the gas valve with the label marked

"LP GAS"

INSTALL LOW GAS PRESSURE SWITCH

NOTE: Install the Low Gas Pressure Switch before installing the

manifold on the burner assembly.

There are 2 ways to mount the Low Gas Pressure Switch.

All 14 3/16-in. (360 mm) Casings or Vent Passes Between

Inducer Assembly and Burner Assembly

If the vent pipe passes between the inducer and burner assembly,

or the furnace is a 14 3/16-in. (360 ram) wide casing, install the

switch as follows (See Fig 12):

1. Remove the 1/8-in. NPT pipe plug from the gas valve inlet

pressure tap.

NOTE: Use pipe dope approved for use with Propane Gas.

NOTE: Tighten all fittings and the Low Gas Pressure Switch

with a small wrench. Do not over-tighten, check for gas leaks

after gas supply has been 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,

2. Apply pipe dope sparingly to the male threads of the

l/8-in, black iron street elbow. Install the street elbow into

the gas valve inlet pressure tap. Point the open end of the

street elbow toward you.

3. Apply pipe dope sparingly to the male threads of the

l/8-in, brass street tee. Install the male end of the street tee

as shown in Fig 12. One opening on the street tee should

face you. The other opening should be parallel with the

inlet of the gas valve.

4. Apply pipe dope sparingly to the male threads of the

l/8-in, brass hex nipple. Install the hex nipple into the

open end of the brass street tee. See Fig 12. The hex nipple

should be parallel with the boss on the gas valve.

5. Install the open end of the brass street elbow on the end of

the hex nipple. Tighten the street elbow so the male

threads of the elbow point away from you.

6. Apply pipe dope sparingly to the male threads of the

l/8-in, brass street elbow. Install the Low Gas Pressure

Switch on the male threads of the street elbow. Tighten

switch at hex fitting at base of switch. Do not use switch

body to tighten switch. Do not over-tighten switch.

7. The remaining opening on the brass street tee is the new

gas valve inlet pressure tap. 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.

8. Check all fittings for leaks after gas supply has been

turned on.

Casings Wider Than 14 3/16-in. (360 mm) / Vent Does Not

Pass Between Inducer and Burner Assembly

1. 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 ram) wide casing, install the switch as follows (See

Fig 13):

2. Remove the l/8-in. NPT pipe plug from the gas valve inlet

pressure tap.

NOTE: Use pipe dope approved for use with Propane Gas.
