20.Set the thermostat to call for heat. The appliance is now ready to operate.

IMPORTANT

Upon completion of any testing on the gas system, leak test all gas connections with a soap solution while main burners are operating. Immediately repair any leak found in the gas train or related components. Do Not operate an appliance with a leak in the gas train, valves or related piping.

Check burner performance by cycling the system while you observe burner response. Burners should ignite promptly. Flame pattern should be stable, see “Maintenance-Normal Flame Pattern.” Turn system off and allow burners to cool, then cycle burners again to ensure proper ignition and flame characteristics.

FIG. 20 F1 Gas Valve 90,000 - 270,000 Btu/hr Models

FIG. 22 M9 Gas Valve 45,000 - 399,999 Btu/hr Models

Each unit has a combination gas valve(s) to control the gas supply to the burners. The 500,000 Btu/hr model has two combination gas valves to supply gas to the burners. The combination valve consists of a gas regulator and two valve seats to meet the requirements for redundant gas valves. The valve has a gas control knob that must remain in the open position at all times when the appliance is in service. Each gas valve has pressure taps located on the inlet and outlet sides. Manifold pressure is adjusted using the regulator located on the valve. The manifold pressure is preset at the factory and adjustment is not usually required. If the manifold pressure is to be adjusted, follow the “Gas Manifold Pressure Adjustment Procedure”, page 15 for proper adjustment.

Venting of Combination Gas Valves

The combination gas valve regulator used on all models is equipped with an integral vent limiting orifice. The vent limiter ensures that the volume of gas emitted from the valve does not exceed the maximum safe leakage rate allowed by agency requirements. Combination gas valve/regulators equipped with integral vent limiters are not required to have vent or relief lines piped to the outdoors. A dust cap is provided at the vent termination point on the valve to prevent blockage of the vent limiter by foreign material. The combination gas valve regulator with an integral vent limiter complies with the safety code requirements of CSD-1, CF-190(a) as shipped from the manufacturer without the installation of additional vent lines.
