Can an oil furnace be direct vented?
DIRECT VENTING OF OLSEN OIL FIRED FURNACES The Direct Vent series is ideal for applications where a conventional chimney is unavailable, nor easily installed; an electrically heated home being retrofit for oil forced air heating for example. The term Direct Vent refers to a sealed combustion system.
Do they make a direct vent oil boiler?
The Direct Vent Intrepid TRDV is a hot water boiler heating system which oil-fired cast iron boiler offers high-efficiency heating without a chimney. Available in hot water models with or without a tankless heater.
Can you vent an oil furnace through the wall?
Direct venting systems eliminate the need for a chimney. An induced draft fan typically provides the draft required to exhaust the combustion products through a side wall. Discharge fittings are designed to pass through combustible walls and minimize the effects of wind on the venting of the combustion products.
Does an oil furnace need to be vented?
Many homes use the Type L vents for the newer and more energy efficient oil burning furnaces. It is imperative to place L Vents under the proper government specifications to prevent home roof fires.
How much ventilation does an oil furnace need?
To summarize, for combustion air, an opening is needed that has at least 28 in. ² of free space per GPH of #2 fuel oil. For ventilation air, two holes are needed, each with at least 140 in. ² of free space per GPH (divide area by 2 for outside air; divide by 2 again for vertical ducts).
Can an oil furnace be vented horizontally?
Both types of heating systems can vent horizontally through a building wall, but the exhaust products of high efficiency or condensing boilers and furnaces are generally cool and have different venting and combustible clearance specifications.
Do you need a chimney for oil heat?
An oil furnace needs a chimney liner. The purpose of any chimney liner, or flue, is to keep the smoke, fumes and toxic gases from penetrating the chimney mortar and entering the living space. The fuel used in an oil furnace creates an oil mist.
How are oil furnaces vented?
Furnaces traditionally relied on the natural lift of hot gas to draw combustion by-products and smoke up and out of the home through a masonry chimney. Power vents use special fans to blow the smoke produced by an oil furnace out through a vent in the side wall of the home instead, eliminating the need for a chimney.
