Furnace venting into attic.
The drain must be installed through the core of the house as water will be flowing during the colder months.
If any gaps remain and the vent isn t airtight the toxic gases will leak back into your home.
As far as terminating a combustion air vent into an attic i hope every one can understand what can happen in that case it is totally opposite of installing a combustion supply air vent.
The stem of the t has soffit vents and no vent at the top.
One of the furnaces is in the attic.
The exhaust system typically uses metal venting often routed into a chimney stack to exhaust the combustion gases created in the furnace fire chamber.
I have a bathroom exhaust fan that is vented directly into the attic.
This structure generally uses the furnace vent pipe through roofbecause the b venting pipe is designed in vertical manner.
The trick to the installation of a gas furnace in an attic space is routing the condensate drain from the attic down through the core of the house to the basement.
A conventional natural gas furnace will vent the dangerous combustion gases through a simple vertical exhaust system that is attached to the furnace.
Also known as the type b this vent is operating on the natural air convection.
A furnace in the attic is a design that works for all homes.
It has started to leak water back through the exhaust fan into the bathroom.
See comment 3 above.
You might not receive the same air movement benefits if the unit is in a garage either.

If you don t have a crawl space or a basement then it can be a challenge to place a furnace on the ground floor of the structure.
The top of the t has soffit vents and a ridge vent.
There are 3 gas furnaces and ac units.
This undermines the entire purpose of venting the furnace in the first place.
Or you may have a distance issue.
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.
This drain removes the excess water that a heating system will generate.
The roof is a t shaped gable roof.
Original installers used pvc to vent the furnace to the roof but combustion air for the furnace is pulled from inside the house.
Taking care of the vent on your gas furnace is extremely important but working improperly and damaging your vent can have catastrophic results.
When the vent is withdrawing air from the house it expels the gas outside through the vent.
The furnace is located in the stem.
