8.For L.P. gas, consult your L.P. gas supplier for expert installation.

IMPORTANT

Upon completion of any piping connections to the gas system, leak test all gas connections with a soap solution while system is under pressure. Immediately repair any leaks found in the gas train or related components. Do Not operate an appliance with a leak in the gas train, valves or related piping.

FIG. 18 Manifold Pressure Adjustment

1.Turn the power “OFF” at the main disconnect switch.

2.Turn gas valve control knob to “PILOT” position on standing pilot models. Ensure that the standing pilot remains on. If the pilot goes out, follow the “Lighting Instructions” for standing pilot models to light the pilot. Turn gas valve control knob to “OFF” position on spark ignition models.

3.Remove the 1/8" hex plug located on the outlet side of the gas valve and install a fitting suitable to connect to a manometer or magnahelic gauge. See Figure 18. Minimum range of scale should be up to 5" w.c. for Natural gas models and 10" w.c. for L.P. gas models.

4.The 500,000 Btu/hr model will have two gas valves with a pressure regulator on each valve. Repeat the following adjustment procedure to set the manifold pressure on each gas valve.

5.Remove pressure regulator adjustment cap screw on the gas valve. See Figure 18 for location.

6.Turn the power “ON” at the main disconnect switch.

7.Turn gas valve control knob to “ON” position.

8.Set the thermostat(s) to call for heat.

9.Observe gas regulator pressure when all burners are firing. See Table D, Manifold Pressure for proper regulator pressure settings.

10.If adjustment is necessary, turn regulator adjustment screw clockwise to raise regulator gas pressure, counterclockwise to lower gas pressure, to proper setting. Note: Adjustment fitting is plastic and may require slightly greater turning force than a metal fitting.

11.Turn the power “OFF” at the main disconnect switch.

NOTE:

Do not increase regulator pressure beyond specified pressure setting.

12.Turn gas valve control knob to “PILOT” position on standing pilot models. Turn gas valve control knob to “OFF” position on spark ignition models.

13.Remove fitting from the gas valve and replace the 1/8" hex plug that was previously removed and tighten.
