Do you glue concentric vent?
To avoid vent failure the installer must use CPVC vent material for the first 7 equivalent feet of a 2 inch PVC vent system. The installer must also utilize primer and glue that is certified for both PVC/CPVC materials.
How far apart do concentric vents need to be?
Allow 8” center-to-center distance between concentric vent terminations on multiple boiler installations (see Fig. 7). It is very important to properly glue all joints. Failure to do so can result in property damage, serious personal injury, or death.
What is concentric venting system?
The Concentric Vent allows both the intake for combustion air and the exhaust vent to pass through a standard roof or sidewall. This is an alternative to the standard two pipe intake/vent shown in the basic furnace installation instructions.
What is a concentric pipe?
Answer. This concentric vent is a pipe within a pipe. When it is installed on an approved product the exhaust is run through the center pipe and make up air is drawn through the outer.
What is a concentric kit used for?
Concentric vents make it easier to have a two-pipe installation for high efficiency furnaces. These vents simplify installation and only require one hole through the wall or roof where the pipes terminate. Without using these vents, the installation would require cutting two holes through the home, one for each pipe.
Can PVC be used to vent a furnace?
Ironically, even though the presence of plastic vent pipes has become synonymous with high-efficiency condensing furnaces, PVC pipe manufacturers do not recommend PVC for this application. Nor are there any official ASTM standards for plastic pipe used as combustion gas venting.
How do you vent a high efficiency furnace outside?
Proper sidewall venting requires installing separate vent pipes horizontally so that they vent to the outdoors through a wall of your home. These ventilation pipes should be isolated from the furnace combustion chamber and made airtight to eliminate the possibility of combustion gas leakage.
How far can you vent a high efficiency furnace?
Allow 6 feet clearance to any mechanical air supply or service regulator vent and 6 feet horizontally to any gas meter, electric meter, or relief device.
What type of venting is used on a high efficiency furnace?
Sidewall Venting
How much clearance does a furnace need?
As a general recommendation, your heater should be 30 inches away from furnace room walls on all sides. This allows our service experts to comfortably replace it. You also need to check the space has enough airflow and ventilation, especially if you have an aging furnace with a metal flue.
Can you put your furnace in a closet?
High-efficiency furnaces may be installed in basements, ground-floor utility rooms, garages or attics, in open spaces or confined closets.
