Vent Termination Clearances - Empire Comfort Systems DVCT40CSP95N-1 Installation Instructions Manual

Termination clearance for buildings with combustible and noncombustible exteriors.
Vertical Sidewall Installations
Important! Minimum clearance between vent pipes and combustible
materials is 3 inch (76 mm) on top, and 1 inch (25 mm) on bottom
and sides.
Important! When vent termination exits through foundation less
than 20 inch (508 mm) 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: 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.
