4. Disconnect Gas Valve power harness.
5. Loosen union above Manual Valve.
For Models 88AR & 108AR (orifice supplied)
6. Remove the two Allen screws holding the Gas
Valve to the Venturi/Blower assembly (see Fig 48).
7. Remove the Gas Valve assembly. This will reveal
the rubber grommet between the Gas Valve and
Venturi assembly.
8. Remove the rubber grommet.
9. Insert the Propane orifice inside this grommet.
There is a thin slot allocated for the orifice to slip
into. (see Fig 49).
10. Re-install grommet in between Venturi and Valve
assembly.
11. Re-install Allen screws to secure Gas Valve
assembly.
12. Tighten union to secure supply line to Gas valve.
13. Turn manual valve back on.
14. See “Gas Valve Adjustment” before running boiler.
