KIT INSTALLATION (SEE ILLUSTRATION)

1. Disconnect the gas line at the union ahead of the combina­tion gas valve.

2. Remove burners from assembly.

A. To Change Burner Orifice

Remove each burner orifice from the manifold. See
Figure 1. Refer to Table 1 and verify the correct burner
orifice size required. Open the burner orifice envelope
marked with the orifice drill size required and install in the
burner when the unit is converted to LP gas.

B. Convert Gas Valve to LP Gas (See Figure 2)

See Honeywell envelope kit #396221-2 for proper LP reg­ulator spring and instructions. If unsure of which spring is
correct for the valve you are converting refer to Figure 3.

Manifold gas pressure must be adjusted to 10ⴖ W.C. after
valve conversion to LP gas with furnace in operation and
proper gas supply pressure (see rating plate). The gas
supply line pressure should be between 11ⴖ and 14ⴖ W.C.
at the appliance.
