Plan the vent system layout to avoid the possibility of accidental contact with concealed wiring or plumbing inside of wall. Single wall vent pipe may be used to join an appliance to the power venter; but, if proper clearance cannot be maintained from combustible material or when passing through a side wall, Class "B" type vent pipe should be used for gas appliances and Class "L" type vent pipe for oil appliances. The power venter should be installed as close to the termination of the vent system as possible to reduce effects of wind, outlet blockage and to guard against flue gas leakage. Pipe joints and seams should be sealed with a high temperature silicone adhesive sealant or equivalent. Test vent connections for leaks by using a soap solution as recommended by the National Fuel Gas Code: A. N. S. I. Vent hood inlet diameter should never be smaller than the installed vent pipe. Cut hole 1/2 inch larger than marked hole to facilitate easy installation.
