Step 9. Reassemble all removed components
by reversing the procedures outlined
in the preceding steps. Use pipe joint
compound or Tefl on tape on all pipe
fi ttings before installing (ensure pro-
pane resistant compounds are used in
propane applications, do not use pipe
joint compounds on fl are fi ttings).
Step 10. Attach the conversion label provided
in the conversion kit to the rating plate
on the appliance.
Step 11.Turn on gas supply and test for gas
leaks.
When reinstalling the Igniter assembly, use
extreme care to prevent damage and break-
age. Do not apply any leverage to the Igniter
assembly while restoring the retainer clip to
its original position.

Step 7. Remove the burner orifi ce from the
manifold and replace it with the one
provided with the kit. See Table 14
for orifi ce sizes required for use with
natural gas or propane gas. Figure 66
illustrated the orifi ce.
Step 6. Electronic Appliances -
Honeywell Systems
See Figure 64 and the instructions provided
with the kit. Remove the slotted cap screw,
o-ring, pressure-regulating adjusting screw
and spring. Retain all parts for possible later
use. Install new components from the kit.
Black cap and red spring for propane gas
units. Silver cap and stainless steel spring
for natural gas units. Before installing the
cap, attach manometer to the manifold side
pressure test fi tting and adjust screw until
pressure reads 3.5 inches water column (0.87
kPa) for natural gas, and 10.0 inches water
column (2.49 kPa) for propane gas.
See Figure 65 and replace the pilot orifi ce
as follows: Remove the Igniter assembly
retainer clip, and carefully remove the Igniter
assembly.
Exercise extreme care to prevent damage to or
breakage of the Igniter assembly. Remove the
screw securing the pilot assembly to its mount-
ing bracket. Back off the fl are nut at the end
of the pilot gas line to free the pilot assembly
from the gas line. Remove the pilot orifi ce
and replace it with the one provided with the
conversion kit. Reinstall the pilot assembly
by reversing the steps detailed here.
