All installations and services must be performed by qualified service personnel.

E. FUEL PIPING

Sizing and installation of fuel lines must be in accordance with Federal, State & Local regulations. Including the National Fuel Gas Code NFPA 54/ANSI-Z233.1 (Latest Edition).

NOTE: These furnaces are designed to be gas piped through the left side or the bottom. For service purposes, it is recommended that the gas union be located inside the furnace when possible.

: Because of the potential of odorant fade, a gas leak may not be detected by smell. If this furnace is installed below grade, contact your gas supplier for a gas detector.

A qualified installer or service person must perform all gas piping and testing. Piping from the natural gas meter to the furnace shall be in accordance with requirements of the local gas utility. Piping from the LP tank to the furnace must follow the recommendations of the gas supplier.

A readily accessible manual shut off valve (certified for the applicable gas) with a non-displaceable rotor member shall be installed within six feet of the gas equipment it serves.

A union or flanged connection shall be provided directly up stream of the burner to allow burner removal. Unions must be of a ground joint type or flange-jointed type using a gasket resistant to the applicable gas. Pipe dope or sealant certified to be resistant to the action of the applicable gases should be used on all threaded joints.

A drip leg must be used on both LP and Natural gas installations prior to the furnace in order to trap oil, condensate and other impurities which might otherwise lodge in the gas valve or plug the burner orifice.

A drip leg shall be provided at the outlet of the gas meter when there is excessive condensation between the gas meter and the furnace. Failure to install a drip leg may void the limited warranty on the furnace.

: All gas pipe connections must be leak tested using methods approved by State, Local and National Fuel Gas Code NFPA 54/ANSI-Z233.1 (Latest Edition). Any leaks must be repaired immediately after turning off the gas supply. A final test for gas leakage must be made after purging the gas line.

: DO NOT wet electronic components during the leak test. Wetting electronic components may damage circuitry and cause a hazardous situation. Dry moisture from all leads and terminals if wetting
