Reznor Reznor® SC Series Separated Combustion, Gas-fired Duct Furnaces Model SC225

Reznor® model SC series separated combustion gas-fired duct furnaces are designed to separate their combustion air from the air in the heated space. Reznor® was the leading pioneer in perfecting separated combustion technology. These units are designed and manufactured in accordance with the ANSI definition of "separate combustion". While discharging exhaust air, the power venter draws in combustion air from the outside atmosphere. Using outside combustion air prevents dirt, lint, dust or other contaminants in the heated space from entering the combustion zone of the furnace. The separated combustion furnace is designed for use in building areas with negative pressure and/or extremely dirty or mildly corrosive atmospheres. A specially designed combustion air inlet/vent terminal assembly supplied with SC series units requires only a single-building penetration for both exhaust and combustion air.
