INSTALL ORIFICES
1. Install main burner orifices. Do not use PTFE thread- seal
tape. Finger-tighten orifices at least one full turn to
prevent cross-threading, then tighten with wrench.
2. There are enough orifices in each kit for largest furnace.
Discard extra orifices.
NOTE: DO NOT reinstall the manifold at this time.
INSTALL MIXER SCREWS
NOTE: There are two sets of mixer screws. One set is for
Condensing gas furnaces, the other set is for Non-condensing
gas furnaces. Use only the parts in the bag marked
“REQUIRED FOR THE CONVERSION OF
NON- CONDENSING GAS FURNACES TO PROPANE GAS”
See Figure 7 to verify you have the correct set of mixer screws.
1. Locate the dimple on each burner venturi tube. If you
cannot locate the dimple, refer to Figure 8 for location of
the mixer screw.
2. Drill a 5/64-in. (2.8 mm) hole (supplied in kit) in each
dimple.
3. Install a mixer screw in each drilled hole drilling as straight
as possible. The screw head should be flush with the top
of the burner venturi.
