Vertical Sidewall Installations
Important! Minimum clearance between vent pipes and combustible
materials is one inch (25 mm) on, bottom and sides and three inches
(51 mm) on top.
Important! When vent termination exits through foundation less
than 20" below siding outcrop, the vent pipe must flush up with the
siding. 46-DVA-HC termination cap must also be used.
Information on Various Venting Routes and Components
Important: It is always best to locate the appliance in such a way
that minimizes the number of offsets and horizontal vent length.
Since it is very important that the venting system maintain its balance
between the combustion air intake and the flue gas exhaust, certain
limitations as to vent configurations apply and must be strictly
adhered to.
The graph showing the relationship between vertical and horizontal
side wall venting will help to determine the various vent lengths
allowable.
The horizontal vent run refers to the total length of vent pipe from
the vent elbow of the appliance to the face of the outer wall.
TERMINATION CLEARANCES
Termination clearance for buildings with combustible and noncombustible exteriors.
