Avoid the use of horizontal runs and elbows if at all
possible. If horizontal runs are necessary, they
should be supported (approximately every 4 feet) to
prevent sagging. Horizontal runs must be installed
without any dips or sags and should slope upward at
a minimum of ¼ inch per foot. The termination vent
pipe should extend at least 3 feet above the highest
point where it passes through a roof of a building
and at least 2 feet higher than any portion of a
building within a horizontal distance of 10 feet.
OUTDOOR INSTALLATION
This heater is certified by International Approval
Services (AGA & CSA) for outdoor installation. If the
heater is installed in very cold areas, proper precautions
are needed for freeze protection. The heater must be
placed in a suitable area on a level, noncombustible
surface. Do not install heater under an overhang with
clearances less than 3 feet from top of the heater. The
area under an overhang must be open on three sides.
IMPORTANT!
In an outdoor installation it is important to
protect your heater from water damage. Ensure
water is diverted from overhanging eves with a
proper gutter/drainage system. The heater must
be set on a level foundation for proper rain
drainage.
Maintain minimum clearances as indicated below. Install
a minimum of 5 feet below, and 4 feet horizontally from
any opening to a building.
The heater should not be installed closer than 6 inches
to any fences, walls or shrubs at any side or back, nor
closer than 16 inches at the plumbing side. A minimum
clearance of 24 inches must be maintained at front of
heater.
