Step 6. All Millivolt Systems Attach ma-
nometer to the manifold side pressure test
fitting and verify manifold 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.
Step 7. Refer to
Figure 29
and remove the
pilot hood assembly to access the hexed pilot
orifice. Remove and replace the orifice with
the one provided with the kit.

Step 12. Turn on gas supply and test for gas
leaks.
Step 10. Reassemble all removed compo-
nents by reversing the procedures outlined in
the preceding steps. Use pipe joint compound
or Teflon tape on all pipe fittings before install-
ing (ensure propane resistant compounds are
used in propane applications, do not use pipe
joint compounds on flare fittings).
Step 11. Attach apropriate conversion kit label
(Figure 33 )
to the rating plate on the appliance.
See
Figure 30
and replace the pilot orifice as
follows: Remove the ignitor assembly retainer
clip, and carefully remove the ignitor assembly.
Exercise extreme care to prevent damage to
or breakage of the ignitor assembly. Remove
the screw securing the pilot assembly to its
mounting bracket. Back off the flare nut at the
end of the pilot gas line to free the pilot assem-
bly from the gas line. Remove the pilot orifice
and replace it with the one provided with the
conversion kit. Reinstall the pilot assembly by
reversing the steps detailed here.
When reinstalling the ignitor assembly, use
extreme care to prevent damage and break-
age. Do not apply any leverage to the ignitor
assembly while restoring the retainer clip to
its original position.

Step 9. Unscrew the orifice from the manifold
and replace it with the one provided with the kit,
#49 (0.073) for natural gas units and (0.045)
for propane
(Figure 32 )
.
Note: If the ignitor assembly is damaged, a replacement kit is available,
order Catalog Number 87L54.

Step 8. Honeywell Electronic Valves - See
Figure 31
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 fro natural
gas units. Before installing the cap, attach
manometer to the manifold side pressure test
fitting 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.
