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 mani-
fold/gas valve assembly to the burner box.
9. Visually inspect orifices for damage and drill size (marked
on face with 55) before installation. Using the 7/16" wrench,
remove all existing natural gas orifices and replace with
the appropriate marked 55 L.P. gas orifices contained in
this kit. Tighten the orifices to prevent gas leaks, but do
not overtighten. Retain the natural gas orifices for future
reconversion.
10. Install water manometer using Valve Pressure Check Kit
P/N 0151K00000S included with this kit. Using the in-
cluded 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
included connector to the hose on the outlet boss. Con-
nect 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.
