Sealed Combustion Duct Furnace

Duct furnaces separate their combustion air form the air in the heated space.

Sealed combustion duct furnace.

The combustion chamber loses less heat to the outside making the furnace cost less to run. The separated combustion furnace is designed for use in building areas with negative pressure and or extremely dirty or mildly corrosive atmospheres. Indoor separated combustion duct furnace modine indoor separated combustion duct furnaces are designed and engineered to deliver superior performance in a variety of applications. In furnaces that are not sealed combustion units backdrafting of combustion gases can be a big problem.

As we already mentioned this is one of its biggest benefits. These types of furnaces have a dedicated pipeline that runs directly from an outside vent into a sealed combustion chamber of the furnace and a sealed vent to the outside of the home for venting the toxic fumes from the combustion process. They are designed for use within a building s duct work with upstream air mover by others. Modine s gas fired duct furnaces are designed for both indoor and outdoor installations.

Primary applications are for building heating cooling and make up air systems. Sales literature technical literature. Reznor s sc separated combustion gas fired duct furnaces are designed to separate their combustion air from the air in the heated space. The highest performance combustion furnaces are sealed combustion direct vent condensing gas furnaces with an annual fuel utilization efficiency afue exceeding 94.

Sterling introduces the nexus unit heater a leading edge condensing heat exchanger delivering up to 97 efficiency. The highest efficiency furnaces today combine sealed combustion with a second condensing heat exchanger. Featuring a single stage two stage or full modulation firing rate this durable 316l stainless steel heat exchanger is available with both natural gas and lp gas flexibility also field. Finally going with.

High efficiency sealed combustion units generally produce an acidic exhaust gas that is not suitable for old unlined chimneys so the exhaust gas should either be vented through a new duct or the chimney should be lined to accommodate the. Also featured is the factory installed power venter and sealed flue collector that controls combustion and excess air during on cycles. Install the highest performing furnace that project funding will allow to meet the heating load of the project. The sealed combustion furnace.

The combustion chamber is the part of the furnace where natural gas is burnt to create the heat that enters into the heat exchanger. Where the furnace draws this air is the difference between standard atmospheric. Both models offer high effciencies that achieve annual fuel savings of up to 25 over conventional duct furnaces.
