Energy Efficiency Regulations

Regulatory Definition

Gas furnace means  an automatic operating  gas-fired central forced air furnace that uses propane or natural gas and has an input rate of not more than 117.23 kW (400,000 Btu/h). It does not include a furnace for a mobile home or for a recreational vehicle.

Through-the-wall means, with respect to a gas furnace, one that is designed and marketed to be installed in an opening in an exterior wall that is fitted with a weatherized sleeve.
