All gas and oil direct heating equipment whose energy input ratings are within the parameters outlined below are included in the program:
"Vented home heating equipment" or "vented heater" means a class of home heating equipment, not including furnaces, designed to furnish warm air to the living space of a residence, directly from the device, without duct connections (except that booths not to exceed 10 inches beyond the casing may be permitted) and includes: vented wall furnaces, vented floor furnace, and vented room heater.
- "Vented floor furnaces" means a self-contained vented heater suspended from the floor of the space being heated, taking air for combustion from outside this space. The vented floor furnace supplies heated air circulated by gravity or by a fan directly into the space to be heated through openings in the casing.
- "Vented room heater" means a self-contained, free standing, non-recessed, vented heater for furnishing warmed air to the space in which it is installed. The vented room heater supplies heated air circulated by gravity or by a fan directly into the space to be heated through openings in the casing.
- "Vented wall furnace" means a self-contained vented heater complete with grilles or the equivalent, designed for incorporation in, or permanent attachment to, a wall or a residence and furnishing heated air circulated by gravity or by a fan directly into the space to be heated through openings in the casing.
