The bulb control switch on the COZY VCR501A-H connects to the gas valve through the blocked flue switch. One wire from the bulb control switch goes to the blocked flue switch, and the other originally connected wire is cut and rerouted. A thermostat wire is connected from the gas valve’s "TH/PP" terminal to the blocked flue switch. This setup allows the bulb control switch to work with the thermostat and blocked flue switch to control the gas valve operation, helping regulate the heater based on temperature and safety conditions.
