TO CONVERT FROM NATURAL TO L.P. GAS
1. Shut OFF gas supply at manual shutoff and turn OFF power to
the furnace.
2. Remove access door.
3. Disconnect wiring from the gas valve.
4. Remove the gas manifold assembly by removing the four
screws connecting it to the burner bracket.
See Figure 2 below.
Figure 2 - Gas Manifold Removal
5. Remove natural gas orifices from gas manifold using 7/16"
box end wrench.
6. Visually inspect L.P. gas orifices (B40899125) for damage and
drill size (marked on face with #125) before installation. In-
stall orifices and tighten with a box-end wrench, take care to
avoid crossthreading or over tightening.
7. Remove the “NAT. GAS” label from the top of the 36J27 gas
valve.
8. Use needle nose pliers to place the jumper (see enclosed F92-
1021 kit) on the receptacle. Make sure both pins engage the
jumper .
9. Place the “L.P.” label (see the enclosed F92-1021 kit) on the
gas valve, covering the jumper installed in step 8.
10. Attach the “WARNING” label (see the enclosed F92-1021 kit)
to the gas valve where it can readily be seen.
11. Attach the gas manifold assembly to the burner bracket using
the four screws removed in step 4.
L.P. GAS PRESSURE CHECK
L.P. Gas Supply Pressure must be verified with all L.P. appliances
in operating mode. See Table 1 for the required L.P. gas pressure.
1. Turn OFF electrical power & gas supply to the unit.
2. Use a 3/16" Allen wrench to remove the 1/8"inlet pressure tap
from the gas valve.
3. Connect a calibrated water manometer or appropriate gas
pressure gauge at the gas valve inlet pressure tap.
4. Turn ON the power and gas, put the unit into heating cycle on
high fire (100%). Tap plub. The pressure must be leak checked
after resealing.len
Minimum: 11" w.c. Maximum: 13" w.c.
Propane Gas Supply Pressure Range
MANIFOLD PRESSURE CHECK
See Table 2 for the required L.P. gas manifold pressure. The gas
valve outlet pressure is automatically adjusted for LP by installa-
tion of the jumper in step 8. Only minor changes to manifold
pressure should be made by adjusting the gas valve pressure
regulator. Minor adjustments may be made by removing the
access plug and turning the fine-adjustment screw with a 1/8"flat
blade screwdriver. Adjustment should only be done while moni-
toring outlet pressure with a suitable manometer properly at-
tached to the outlet pressure tap.
Propane Gas Manifold Pressure Range
Low Stage High Stage
2.3" - 2.7" w.c. 9.7" - 10.3" w.c.
1. Turn OFF electrical power & gas supply to the unit.
2. Use a 3/16"Allen wrench to remove the 1/8"outlet pressure
tap from the gas valve.
3. Connect a calibrated water manometer or appropriate gas
pressure gauge at the gas valve outlet pressure tap.
4. Turn ON the power and gas, put the unit into heating cycle on
high fire (100%).
5. Remove the White cap located on top the gas valve next to the
+ & - symbols.
6. Use a 1/8"flat blade screwdriver to turn the fine adjustment
screw; clockwise (+) to increase manifold pressure, counter-
clockwise (-) to decrease manifold pressure.
7. After adjustment is made, turn OFF gas to the unit at the manual
shutoff valve and disconnect manometer. Reinstall line pres-
sure tap plug. The pressure tap must be leak checked after
resealing.
