INSTALLATION CAUTION: Shut off gas supply before working on appliance. 1. Remove thermocouple from gas control valve. (See Figure 1) 2. Thread the junction block into the thermocouple port and thread the thermocouple into the bottom of the junction block. DO NOT over tighten the junction block. Hand tread the block into thermocouple port then tighten lightly with a wrench. 3. Mount the two (2) spill switches onto the draft hood so the switches do not contact any metal. (See Figure 2) Figure 1 4.
