Table illustrations of the required space between a direct or side wall vent for a gas fired heating appliance and building windows doors corners gas meter air intakes sidewalks balconies.
Which means you may not use abs or pvc cement to attach it to your venting.
This high efficiency venting system must be installed when you install the new furnace.
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.
You need to make sure your furnace is venting properly.
Combustion products must be discharged outdoors.
The flue is also a safeguard against fire.
Other aspects of high efficiency furnace venting.
Connect this furnace to an approved vent system only as specified in the venting requirements section of these instructions.
These pvc pipes are connected to the furnace and expelled outside.
Gas appliance direct vent clearances distances from direct gas vent to building features sidewall vent direct vent direct exhaust systems for gas fired heaters water heaters other appliances.

The vent pipe or flue is a vital component of the furnace that transmits emissions from the combustion process out of the building.
These are connected to the furnace and routed out to the side of your home.
That way should there be a problem with the furnace that causes the exhaust temperature to exceed design the exhaust vent system has almost 40 more capacity to handle the excess heat before it reaches the point where it can fail.

Adequate clearance must be provided around the vent air intake terminals.
This structure generally uses the furnace vent pipe through roofbecause the b venting pipe is designed in vertical manner.
The venting system is installed at the same time as your high efficiency furnace.
The pvc pipes are used for air intake exhaust gas and to remove the corrosive condensation resulting from the combustion process.
