d. Locate the two (2) latches at the top of the
control compartment. To disengage the two
latches from the bottom vee-flange of the glass
enclosure panel, reach for the handles located
towards the back of the latches and pull the
handles down toward the front of the unit. See
Figure 63 on page 34.
e. Swing the bottom of the door out and raise
it slightly to lift the top flange of the door frame
away from the appliance.
Step 2. Carefully remove the log set. Exercise
care as not to break the log set.
Step 3. Referring to Figure 67, remove the
burner.

Step 4. Refer to Figure 68 and the instruc-
tions provided with the kit. Using a Torx T20,
remove and discard the three pressure regulator
mounting screws. Remove the pressure regu-
lator, spring, poppet, diaphragm and bushing.
Discard all removed components. Ensure
the rubber gasket installed on the back of the
replacement pressure regulator is properly
positioned and install the new pressure regula-
tor using the new screws supplied with the kit.
Tighten screws to 25 In. lb. torque.

Step 8. (Refer to Figure 67 )
A. Remove the orifice from the manifold and
replace it with the one provided in the kit.
The following table shows the orifice sizes
for natural and propane models. Figure 72
illustrates the orifice. Always check and verify
correct orifice size.
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.
Note: If the ignitor is damaged, a replacement kit
is available, order Catalog No. 87L54.

Step 7. Honeywell Electronic Valves - See
Figure 70 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 fitting and adjust
screw until pressure reads 3.5 inches water col-
umn (0.87 kPa) for natural gas, and 10.0 inches
water column (2.49 kPa) for propane gas.
See Figure 71 and replace the pilot orifice as fol-
lows: 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.
Step 5. Attach manometer to the manifold side
pressure test fitting and verify manifold pres-
sure 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 6. Refer to Figure 69 and remove the
pilot hood assembly to access the hexed pilot
orifice. Remove and replace the orifice with the
one provided with the kit.
