Each gas-fired appliance is wired according to the specific make and model. A wiring diagram is included in the appliance manufacturer’ s installation and operation manual. All electrical connections must be made in accordance with the manufacturer’ s installation instructions. Read these instructions and follow them carefully.
Only a certified HVAC technician or someone with similar qualifications and/or experience should attempt to wire a gas-fired appliance.
All local codes and regulations for wiring gas-fired appliances must take precedence over the instructions in the manufacturer’s installation and operation manuals. In the absence of local codes, all electrical wiring and connections should conform with the appropriate instructions and provisions found in the latest edition of the National Electrical Code.
