PART 7 – GAS PIPING
WARNING
FIRE AND/OR EXPLOSION HAZARD
To avoid serious injury or death, the gas line installation and the gas line inlet pressure test must be done by a licensed professional.
Always match the appliance with the type of gas supplied to the unit (natural gas or LP gas). This appliance must be converted into propane
operation unless specically manufactured for use with propane. Follow Gas Conversion Manual instructions (separate document). Propane
ready appliances have the sufx “LP" after the model serial number.
Failure to ensure the appliance is set to operate on the provided gas supply could result in property damage, personal injury, or death.
1. Gas Pipe Sizing
This information is for reference use only. Refer to gas pipe manufacturer specications for actual delivery capacity. The DOE standard for Natural
Gas is 1100 BTU/ft . Contact the local gas supplier for actual BTU/ft rating.
