If it isn't flowing, replace the SmartValve. Use an ac voltmeter to measure the voltage across terminals TH and TR. To avoid the dangerous accumulation of fuel gas, turn off the gas supply at the appliance service valve before starting the installation, and perform Gas Leak Test after completion of installation. Inlet and outlet pressure taps included; both taps accessible from the top of gas control. Install control and appliance according to appliance manufacturer instructions. As the pressure inside the gas control and underneath the automatic valve diaphragm equalizes, spring pressure closes the second automatic valve to provide a second barrier to gas flow. Kit for conversion from LP to natural gas is available for standard and slow opening models. MILLIVOLT SYSTEMS Millivolt systems provide their own power, so do not require outside battery power or line voltage to operate. mention that I got the main burner to light on 2 occassions by tapping on either the gas pipe before the main shutoff valve, or on the honeywell gas millivolt valve itself. 0000019943 00000 n 0000007879 00000 n Ensure the installer is a trained, experienced service technician.
