Sealed Combustion Duct Furnace

Where the furnace draws this air is the difference between standard atmospheric.

Sealed combustion duct furnace.

Also featured is the factory installed power venter and sealed flue collector that controls combustion and excess air during on cycles. 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. In furnaces that are not sealed combustion units backdrafting of combustion gases can be a big problem. Sealed combustion also makes a furnace more energy efficient.

The sealed combustion furnace. 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.

The separated combustion furnace is designed for use in building areas with negative pressure and or extremely dirty or mildly corrosive atmospheres. As we already mentioned this is one of its biggest benefits. They are designed for use within a building s duct work with upstream air mover by others. Install the highest performing furnace that project funding will allow to meet the heating load of the project.

For combustion to occur the furnace needs to draw in air to mingle with the gas from the burners. Both models offer high effciencies that achieve annual fuel savings of up to 25 over conventional duct furnaces. The combustion chamber is the part of the furnace where natural gas is burnt to create the heat that enters into the heat exchanger. Finally going with.

Sterling introduces the nexus unit heater a leading edge condensing heat exchanger delivering up to 97 efficiency. The combustion chamber loses less heat to the outside making the furnace cost less to run. 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. 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 efficiency furnaces today combine sealed combustion with a second condensing heat exchanger. Duct furnaces separate their combustion air form the air in the heated space. Due to high efficiency furnaces having their own fresh air intake no air is drawn from inside your home.
