If you need to short the gas valve coil to the TH or TH-TP terminal to start your EPG 250, it likely indicates a malfunction in the thermostat or control circuitry. This shorting bypasses the normal control signals, directly energizing the gas valve and allowing the unit to ignite. The issue could stem from a faulty thermostat, wiring problems, or a defective gas valve coil that prevents it from receiving the proper signals to open. It's advisable to troubleshoot and repair the underlying issue to ensure safe and reliable operation.
