TYPE B-VENT INSTALLATION
(Listed B-0 or Greater)
Before beginning installation be sure that the
overall height and gas vent size conform to
building code requirements. Gas vents ex-
tending through pitched roofs can extend a
minimum height of at least 600 mm (2')
higher than any obstruction within 3m (10').
Gas vents extending through flat roofs are
required to extend at least 600 mm (2') above
the roof and at least 600 mm (2') higher than
any portion of the building or adjoining build-
ing within 3m (10') of the gas vent.
• Venting instruction contained in this
manual may or may not appy to your
area. Consult your local authority for re-
quirement in your area.
• Where the gas vent extends through ac-
cessible spaces, it should be enclosed to
avoid personal contact and damage. En-
closure walls should have a fire rating
equal to or greater than the floors through
which the gas vent passes except in single
or two-family dwellings.
• Situate the gas vent in the structure so
that it can be installed without cutting
joists, sills, plates, or major load bearing
partitions or members. It is also impor-
tant to locate the base of the gas vent as
near as possible to the heating appliance.
• This heater must be properly connected to
a venting system. This heater is equipped
with a vent safety shutoff system.
• Use only vents labeled "FOR EXTE-
RIOR USE" above the roofline.
• Consult the authority having jurisdiction to
select the correct gas vent diameter. Avoid
using a larger than necessary diameter.
Figure 19, 20 and 21 show other options for
the gas vent. When venting through a side
wall your vent pipe must have the proper
temperature rating (see Figure 21).
Manufacturer's clearances must also be
maintained. Consult the authority having
jurisdiction in your area regarding venting
through side wall.
