Step 5. Millivolt Systems – Attach manom- eter to the manifold side pressure test fitting and verify manifold pressure reads 3.5 inches water column (0.87 kPa) for natural gas, and
10.0inches water column (2.49 kPa) for pro- pane gas.
Step 6. See Figure 26 and remove the pilot hood assembly to access the hexed pilot ori- fice. Remove and replace the orifice with the one provided with the kit.

Step 7. SIT Electronic Valves - See Figure 28 and the instructions provided with the kit. Remove the slotted cap screw,
Modify the pressure regulator from the kit. Using a standard tin snip cutting tool, proceed to trim shoulder off of the regulator.
Install new components and modified pres- sure regulator from the kit.
Attach manometer to the manifold side pres- sure test fitting and adjust screw until 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.

Refer to Figure 27 and replace the pilot orifice as follows: Remove the pilot hood assemble to access the hexed polot ofifice.
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.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
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 8. Unscrew the orifice from the manifold and replace it with the one provided with the kit. See the following table for orifice sizes for natural and propane models. Figure 29 illus- trates the orifice.

Step 9. 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 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. (See step 6 on page 8.)
