Can you use ABS for furnace venting?

Can you use ABS for furnace venting?

PVC or ABS plastic piping is often used on high-efficiency heating and water heating systems as vent piping for the exhaust gases, since the exhaust temperatures are relatively low. This piping is often vented out the side of the home. This includes high-efficiency furnaces, boilers, and water heaters.

Can PVC be used for furnace vent?

Suitable materials for the vent and condensate pipes include PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride), and ABS (acrylonitrile-butadiene-styrene) plastic pipe, depending on the furnace’s specified exhaust gas temperature.

Which is better PVC or ABS pipe?

PVC is more flexible than ABS, but ABS is stronger and more shock resistant. ABS is better at handling severely cold temperatures, but it can warp with exposure to direct sunlight. PVC is thought to be better at muffling the sound of running water.

What type of pipe is used for gas furnace exhaust?

PVC
A gas wall heater or older forced-air furnace generally requires a type “B” double wall metal vent pipe, while a new high-efficiency furnace requires a schedule 40 PVC vent pipe.

Is ABS pipe banned in Canada?

only plastic pipes produced to CSA standards are allowed, except for acrylonitrile-butadiene-styrene (ABS) pipe produced to ASTM F 628, Standard Specification for Acrylonitrile-butadiene-styrene (ABS) Schedule 40 Plastic Drain, Waste, and Vent Pipe with a Cellular Core; HDPE pipe produced to CSA B182.

Can you use cellular core PVC for venting?

DO NOT use Cellular Core PVC/CPVC or Radel for venting exhaust. Use of these materials for exhaust may result in property damage, personal injury, or death.

Why is PVC pipe used for venting on condensing furnaces?

This combination of carbon dioxide and water would damage the type of vents used in conventional systems which run vertically out of a home. To combat this issue, high efficiency condensing furnace uses PVC pipes to extract the acidic water from your home.

Can you use PVC to vent a hot water tank?

PVC is fine. As Jason mentioned, plastic (PVC or ABS) is ok to use as a venting material on powervented hot water heaters. They work by sending a huge amount of air in with the flue gases that it decreases the temperature of the exhaust going through the vent enough that it will not comprimise the vent.

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 is B type venting?

Type B vents are vents suitable only for listed, draft-hood equipped, gas-fired appliances, including most domestic heating and hot water systems.

What type of PVC pipe should I use for a furnace vent?

Recommendations aside, though, it is the installation contractor who ultimately determines which plastic pipe to use. Despite the confusion, the safe practice would suggest the use of PVC schedule 40 pipes for the air intake vent on the furnace and CPVC for the exhaust flue vent, given its higher service temperature.

Are ABS pipes better than PVC pipes?

But since pipes aren’t meant to be seen, plumbers are usually more interested in other qualities. For example, PVC is more flexible, but ABS is stronger and more shock resistant. ABS is better at handling severely cold temperatures, but it can warp with exposure to direct sunlight. PVC is thought to be better at muffling the sound of running water.

Can Kitchener Utilities replace the ABS pipes on my furnace?

If you rent your furnace and hot-water heater from Kitchener Utilities, the city-owned enterprise will remove and replace the ABS pipes at its expense. But if workers must cut holes in a finished ceiling to remove the old pipes and install the new ones, you must pay for the repairs to the ceiling.

What are the different types of furnace venting systems?

Types of High-Efficiency Furnace Venting Systems There are two types of condensing furnaces: two-pipe, or direct-vent, systems and single-pipe systems, which have non-direct venting. Direct-vent (two-pipe) system: The two-pipe system is most common in home heating applications.
