Can you use B vent for oil furnace?

Furnaces with positive pressure and those that burn oil cannot use B-venting. Condensing appliances, such as type IV positive-pressure furnaces, cannot use B-venting. The metal of the vent and the water from condensation can eventually lead to problems in the line.

What type of pipe is used for oil furnace exhaust?

Both gas and oil furnaces use masonry chimney flue vents that handle a temperature range from 350 F to 1800 F degrees. According to HVAC, condensation builds inside of vents promoting deterioration of the furnace. Clay or tile flue liners help with proper evaporation.

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.

How do you vent a high efficiency furnace?

To avoid this problem, high efficiency furnace venting requires the use of PVC pipes instead of metal pipes to remove the acidic condensate from your home. These PVC pipes are connected to the furnace and expelled outside. This high efficiency venting system must be installed when you install the new furnace.

How hot does oil furnace exhaust pipe get?

The temperature in the flue pipe of your furnace can run as high as 400 degrees Celsius, which is about 750 degrees Fahrenheit.

Can I direct vent my oil furnace?

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.

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 high efficiency furnaces be vented vertically?

This system requires PVC piping for the air intake and the exhaust vents to be routed through the sidewall. Vertical venting that pre-exists is unsuitable for the exhaust this system does create.

What type of venting does a high efficiency furnace use?

1. Sidewall Venting (High efficiency appliances) This type of venting uses a 1 or 2 pipe system. An intake and an exhaust pipe are run separately and can be placed through almost any exterior wall, so they provide greater placement flexibility for a new furnace.

Can I vent my furnace out the side of my house?

If your furnace has an AFUE rating of 90 percent or above, it will have a flue pipe that goes out of the side of your house. That’s because the combustion byproducts are in a liquid form, so they need to be drained out of your home in a similar way that the condensation from your air conditioner is drained outside.

What to know about your furnace’s exhaust flue?

3 Things to Know About Your Furnace’s Exhaust Flue 1 Flues Vent Exhaust Gases#N#In a perfect furnace, the combustion of natural gas would generate only two side effects:… 2 Most Furnaces Use Natural Draft#N#Unless you own a high-efficiency condensing furnace, chances are your flue system… 3 High-Efficiency Furnaces Use Draft Inducers More

What is high efficiency furnace venting?

This high efficiency venting system must be installed when you install the new furnace. The PVC pipes are used for air intake, exhaust gas, and to remove the corrosive condensation resulting from the combustion process. There are several other important aspects of high efficiency furnace venting. Most specifically:

What is an exhaust system in a furnace?

The exhaust system typically uses metal venting, often routed into a chimney stack, to exhaust the combustion gases created in the furnace fire chamber. However, these combustion gases contain residual heat that is lost through the ventilation.

Will high efficiency furnace venting ruin my gas furnace?

It will ruin the standard venting equipment that is used in conventional gas furnace ventilation systems. To avoid this problem, high efficiency furnace venting requires the use of PVC pipes instead of metal pipes to remove the acidic condensate from your home. These PVC pipes are connected to the furnace and expelled outside.
