FIRE, EXPLOSION, ELECTRICAL SHOCK

HAZARD

Failure to follow this warning could result in personal

injury, death or property damage.
Gas supply MUST be shut off before disconnecting

electrical power and proceeding with conversion.

WARNING

ELECTRICAL SHOCK, FIRE OR EXPLOSION

HAZARD

Failure to follow this warning could result in personal

injury, 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.

WARNING

Refer to Fig. 8 and 9.

Fig. 9 -- Removing Propane Jumper

NOTE

: The Propane jumper for the modulating gas valve is

very small. Needle-nose pliers are required to remove the jumper
from the gas valve.

1. Locate the round

“LP 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. Remove the small black plastic Propane jumper from the

gas valve.

5. Cover the opening in the gas valve with a small piece of

black electrical tape.

REMOVE LOW GAS PRESSURE SWITCH

NOTE

: There are 2 ways that the Low Gas Pressure Switch

(LGPS) could have been installed during the original natural to
Propane gas conversion.

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 mm) wide casing, the switch
may have been installed as follows. (See Fig 10.)

1. Remove low gas pressure switch, brass street 90

elbow,

brass Hex nipple, brass tee and black iron street 90

elbow

from the gas valve inlet pressure tap. (See Fig 10.)
