TDVN Series Direct Vent Gas Fireplace Troubleshooting SIT Millivolt Valve NOTE: Before troubleshooting the gas control system, be sure external shut off is in the “ON” position. WARNING: Before doing any gas control service work, remove glass front! Table 1 Valve Type NOVA MV Plus Main Operator Minimum Voltage 145mV Coil Resistance 2.25Ω ± 0.5Ω Safety Magnet Hold-in Current Less than 285mA Drop-out Current Greater than 125mA Coil Resistance 0.108Ω ± 0.003Ω System Checks Problem Pilot will not light.
TDVN Series Direct Vent Gas Fireplace System Checks (continued) Problem Possible Cause Defective thermo-generator. (Millivolt system) Defective safety magnet. (mv Plus systems) Defective Safety Magnet (Millivolt system) Pilot orifice blocked. Pilot drops out. Wrong pilot orifice. No gas to main burner Low gas pressure to appliance. Pilot not lit. Control knob not in ON Thermostat/wall switch will not cycle main burner. 20007636 Thermostat not in ON position.
TDVN Series Direct Vent Gas Fireplace System Checks (continued) Problem Possible Cause Solution Thermo-generator output voltage not within design parameters. After the pilot has been lit for approximately three minutes, and only the thermo-generator wire connected to the main operator head, measure the voltage across TPTH and TP. This open circuit voltage should be between 500mv and 750mv. Tune the pilot adjustment screw until the mv reading falls within these parameters.
