in propane applications, do not use pipe joint
compounds on flare fittings).
Step 9. Attach the conversion label provided
in the conversion kit to the rating plate on the
appliance.
Step 10. Turn on gas supply and test for gas
leaks.

See
Figure 38 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. Be-
fore 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.
See
Figure 39 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
assembly 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.
