PVC-DWV, or ABS-DWV pipe and pipe cement. Dakota Sourcing Concentric Vent Kits meet UL-1738 or ULC-S636
requirements.

result in fire, personal injury or death.
● Do not operate the furnace until the installation and assembly of the Concentric Vent and all piping are completed.
Failure to follow this warning could result in product damage or improper operation, personal injury or death.
● Recirculation of flue gasses may occur, causing the intake pipe to freeze shut during cold weather operation if the
venting system is not installed per these guidelines. If the venting system is not installed properly, flue gas may
recirculate, possibly causing the intake pipe to freeze shut during cold weather.

to complete installation.
● The concentric design make intake fresh air cut off exhausting smoke. Preferred vertical roof termination which is
less susceptible to damage, reduces the chance of intaking contaminants, and has less visible vent vapors. Horizontal
side wall termination installation.Dakoat Sourcing also provide side wall horizontal termination kit as more options.
Vent screens are available for necessary applications.
