9. Loosen and remove the Orifice from the (1/4

)
pipe.
10. Apply pipe sealant to threads and reinstall the
new Orifice to the (1/4
”) pipe. Replace with the
appropriate orifice for the new gas type ( Refer
to Table 1 ).
NOTE : Ensure the tapered portion of the Orifice
points straight upward when installed to the
Gas Valve Assembly.
NOTE : Extra care should be taken to avoid turning
the pipe too far into the orifice. The pipe
should not restrict gas flow through the
orifice. A drill bit may be used as a stop-
guide if placed down through the Orifice
opening while threading the Orifice onto
the pipe. When the Orifice is properly
threaded onto the pipe, remove the drill bit
from the Orifice opening and ensure the
drill bit is removed before continuing
assembly.
11. Place the Gas Valve assembly with the Orifice
inside the Burner and allow the Gas Valve to
rest in the support bracket.
12. Install the
3/8” Hex Bolt thru the cabinet bottom
and into the bottom of the Orifice. Tighten
securely.
13. Apply pipe sealant to the threads and snugly
reinstall the ball valve, elbow, and (1/2
”) M-to-M
Pipe to the Gas Valve.
