Step 5. Attach manometer 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 6. Refer to Figure 49 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 7. Dexen Electronic Valves -
See Figure 50 and the instructions provided
with the kit. Remove and discard the two
pressure regulator mounting screws. Re-
move the pressure regulator and diaphragm.
Discard all removed components. Ensure the
provided diaphragm is installed properly onto
the replacement pressure regulator and install
the new pressure regulator using the new
screws supplied with the kit. Tighten screws.
See Figure 51 and replace the pilot orifice
as follows: Remove pilot hood assembly to
access the phillipped pilot orifice. Remove
and replace the orifice with the one pro-
vided with the kit. Exercise extreme care
to prevent damage to or breakage of the
ignitor assembly.

Step 8. (Refer to Figure 47 on page 28 )
A. Remove the orifice from the manifold and
replace it with the one provided in the kit. See
the following table for orifice sizes for natural
and propane models . Figure 52 illustrates the
orifice.
B. Retrieve the burner and slide the venturi tube
over the orifice. Set the shutter adjusting
opening as shown in Figure 43 , page 25.

Step 9. Reassemble the remaining 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 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.
