VENTING REQUIREMENTS
Standard two pipe venting and concentric
vent kits are certified by A.G.A. and C.G.A.
as venting methods for our Separated
Combustion Models QVSB, QVSD and
QVSF. No other venting arrangements are
approved or certified for use with Sterling
Separated Combustion Unit Heaters and
Duct Furnaces.
All pipes are field supplied; 24 gauge single
wall galvanized steel is recommended. All
joints must be sealed with either high
temperature silicone or aluminum foil tape.
The maximum vent length for the combus-
tion air inlet is 50 equivalent feet. The
maximum vent length for the flue gas outlet
is also 50 equivalent feet. Allow 10 equiva-
lent feet for each 90 degree elbow, and 5
equivalent feet for each 45 degree elbow.
