CONVERSION INSTRUCTIONS
NOTE: For low NOx models, see table of contents for
NOx screen section.
1. Turn off the gas supply to the furnace.
2. Turn off the electrical power to the furnace.
3. Remove the furnace control access panel.
4. Check for the presence of NOx screen and remove per
NOx instruction.
5. Separate the gas supply union and remove associated
downstream piping.
6. Always use a backup wrench when removing or replacing
piping to avoid any undue strains or rotation of controls.
7. Remove the wires from the gas valve.
8. Remove the 4 sheet metal screws that fasten the manifold/
gas valve assembly to the burner box.
9. Visually inspect orifi ces for damage and drill size (marked
on face with 1.25mm) before installation. Using the 7/16”
wrench, remove all existing natural gas orifi ces and re-
place with the appropriate 1.25mm L.P. gas orifi ces con-
tained in this kit. Tighten the orifi ces to prevent gas leaks,
but do not overtighten. Retain the natural gas orifi ces for
future reconversion.
10. Install water manometer using Valve Pressure Check Kit
P/N 0151K00000S included with this kit. Using the includ-
ed 3/32” hex wrench, rotate outlet pressure tap screw one
revolution counterclockwise. Attach the included 5/16”
hose to the inlet and outlet pressure boss of the valve.
Hose should overlap boss 3/8”. Connect 5/16” side of in-
cluded connector to the hose on the outlet boss. Connect
1/4” side of the connector to the manometer hose. The
manometer must have a scale range of at least 0” to 20”
of water column.
WARNING
TO PREVENT THE POSSIBILITY OF GAS LEAKS, THE PIPE JOINT COM-
POUND OR PIPE THREAD TAPE MUST BE RESISTANT TO L.P. GAS.
CAUTION
IF NOX SCREENS ARE PRESENT, REMOVE AS PER INSTRUCTIONS IN
SECTION “NOX SCREEN REMOVAL.”
CAUTION
TO PREVENT UNSATISFACTORY FURNACE OPERATION, THE PROPER
GAS CONVERSION KIT MUST BE USED FOR THE GAS VALVE. USE THE
WHITE-RODGERS SPRING KIT ONLY WITH THE WHITE-RODGERS
GAS VALVE.
11. Remove both regulator cover screws.
12. Using a 1/4” fl at blade screwdriver, remove both regulator
adjustment screws (beneath the cover screws).
13.Remove both Natural Gas regulator springs (color-coded
silver/plain) from regulator sleeves and retain with the
Natural Gas orifi ces for future reconversion.
14. Insert the L.P. regulator springs (provided in the conver-
sion kit and color-coded white) into the regulator sleeves.
15. Replace the High regulator adjustment screw and adjust
it clockwise to bottom stop. Follow instructions below
beginning in step 26 for checking & adjustment to verify
manifold pressure falls into the desired range.
16. Replace the Low regulator adjustment screw and adjust
it clockwise to bottom stop. Follow instructions below
beginning with step 25 for checking & adjustment to verify
manifold pressure falls into the deisred range.
17. Reinstall the manifold/gas valve assembly into the appli-
ance. Rewire the gas valve.
18. Apply a liberal amount of pipe joint compound or pipe
thread tape to the threads and reassemble the piping
previously removed.
19. Turn on the gas supply.
20. Using a soap and water solution, check for leaks around
the gas valve/manifold connection.
21. Turn on the electrical supply.
22. Adjust the room thermostat to obtain a fi rst stage (W1
only) burner operation.
