Conversion Kit Instructions

BEFORE BEGINNING CONVERSION:

VALVE IDENTIFICATION

Before beginning conversion, the type valve you have

must be identiﬁ ed. Compare the gas valve presently on the

equipment to the drawing below to identify the correct valve

you are working with. Page numbers for the instructions for

that valve are below each drawing.

White-Rodgers 36G22 and 36J22

See following Instructions for these valves.

CONVERSION INSTRUCTIONS

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 VALVES.

NOTE: For low NOx models, see page 6 for NOx screens.

1. Turn off gas supply to the furnace.

2. Turn off the electrical power to the furnace.

3. Remove the furnace control access panel.

4. Separate the gas supply union and remove associated

downstream piping.

NOTE: Always use a backup wrench when removing or

replacing piping to avoid any undue strains or rotation of

controls.

5. Remove the wires from the gas valve.

6. Remove the 4 sheet metal screws that fasten the manifold/

gas valve assembly to the burner box.

7. 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.

8. 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.
