9. Loosen and remove the Orifice from the
12.7mm (1/2
″) pipe.
10. Apply pipe sealant to threads and reinstall the
new Orifice to the 12.7mm (1/2”) 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 machine screw 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 19mm (¾”)
M-to-M Pipe to the Gas Valve.
14. Reconnect the wires to the Gas Valve
assembly and ensure the wires are connected
to the proper terminals.
15. Apply pipe sealant to the threads of the Ball
Valve and connect the gas supply hose.
16. Turn the main gas supply ON.
17. Turn the Ball Valve to the ON position.
18. Check for gas leaks. (A soap and water
mixture works well.) Allow all areas to
completely dry.
19. Connect the heater to the power source.
20. Turn the toggle switch, located on the control
panel, to the ON position.

the gas valve. NOTE: A standard barbed fitting
may be required for this connection.
7. Reconnect gas, power supply, and turn the Ball
Valve ON.
8. Start heater and monitor the supply and
operating pressures.
9. Check supply pressure to ensure supply pressure
is within the heater’s operating limits (See Table
1, Gas/Air Requirements).
10. Adjust the gas valve regulator to set the
operating pressure as specified in Table 1,
Gas/Air Requirements. The plastic regulator
adjustment screw is already sealed after
adjustment.
