Step 8. Reassemble all removed components

by reversing the procedures outlined in the

preceding steps. Use pipe joint compound or

Teflon tape on all pipe fittings before installing

(ensure propane resistant compounds are used

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.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Remove the pilot orifice and replace it with the

one provided with the conversion kit. Reinstall

the pilot assembly by reversing the steps de-

tailed 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.

Note: If the ignitor is damaged, a replacement

kit is available - order Catalog Number 87L54.

All Models

Step 7. Remove the orifice from the mani-

fold and replace it with the one provided with

the kit. See the following table for orifice sizes

for natural and propane models

. Figure 70

illustrates the orifice.

Figure 68

Step 6. Electronic Appliances -

Honeywell Systems

See

Figure 68

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

column (0.87 kPa) for natural gas, and 10.0

inches water column (2.49 kPa) for propane gas.

See

Figure 69

and replace the pilot orifice as

follows: Remove the ignitor assembly retainer

clip, and carefully remove the ignitor assem-

bly. Exercise extreme care to prevent dam-

age 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.

Use a 7/16" open end wrench and turn the pilot

hex fitting counter-clockwise 1/4 turn. (

refer

to

Figure 64 ).

e. Retighten, clockwise, the pilot hex fitting

until the pilot hood aligns with the thermo-

couple and thermopile as indicated by the

arrows shown in

Figure 64

Note - The orifice strip tab may be randomly

located on any side of the hex fitting.

d. Push the orifice strip tab all the way against

the hex fitting to align the appropriate gas type

orifice

(refer to Figures 65 and 66)

. The type

of gas for which the pilot is set, is, the gas type

shown on the tab.

Step 5. Millivolt Appliances -

Convert the gas valve as follows (

see

Figure 67

)

:

Remove the plastic protecting cap. Remove the

gas type setting screw by turning it counter-

clockwise. Obtain the replacement gas type

setting screw from the kit and screw it into

place (red for propane and blue for natural gas).

Tighten the gas type setting screw by turning it

clockwise. Replace the plastic protecting cap.

b. 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.

Convert the pilot orifice as follows (refer to

Figures 64, 65 and 66 ):

Note - Use extra care not to engage the orifice

strip with the 7/16" open end wrench (contact-

ing the orifice strip could cause strip distortion

rendering the pilot inoperative). Also avoid

wrench contact to any of the other pilot parts.
