Vent Termination Clearances - Empire Comfort Systems DVCP36PP30N-1 Installation Instructions And Owner's Manual

VENT TERMINATION CLEARANCES

Termination clearance for buildings with combustible and noncombustible exteriors.
Vertical Sidewall Installations
Important! Minimum clearance between vent pipes and
combustible materials is 3 inch on top, and 1 inch on bottom and
sides.
Important! When vent termination exits through foundation less
than 20 inch below siding outcrop, the vent pipe must extend
outward so that the horizontal vent termination is located flush to,
or beyond the outcrop siding.
Information on Various Venting Routes and Components
Important: It is always best to locate the fireplace 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. See allowed vent configurations,
page 28 to 32.

The horizontal vent run refers to the total length of vent pipe from
the flue collar of the fireplace to the face of the outer wall.
