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.
2.3 Adjust the Manifold Pressure
Qualified Gas Technician Use Only!
1. Turn the toggle switch, located on the control panel,
to the OFF position.
2. Disconnect heater from the power source.
3. Turn the Ball Valve to the CLOSED position.
4. Turn OFF gas supply at source.
5. Completely loosen pressure tap and remove regulator
screw metal cap on gas valve.
NOTE: Do not remove the plastic regulator adjustment
screw beneath the metal cap.
6. Fit a gas pressure gauge on the pressure tap of 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.
11. Replace the regulator screw metal cap.
12. Turn OFF heater.
13. Remove gas pressure gauge and tighten the pressure
tap securely.
14. Verify proper heater operation and perform gas leak
test at the Pressure Tap.
