Sidewall venting

Venting of flue products
The sidewall vent cap shall terminate at least 3 feet above
any forced air inlet within 10 feet.
The sidewall vent shall terminate at least 4 feet below, 4 feet
horizontally from or 1 foot above any door, window, or
gravity air inlet to the building.
Do not terminate the sidewall vent in a window well,
stairwell, alcove courtyard, or other recessed area. The
sidewall vent can not terminate below grade.
The sidewall vent system shall terminate at least 1 foot
above grade, above normal snow levels, and at least 7 feet
above grade when located adjacent to public walkways. The
sidewall vent shall not terminate directly above a public
walkway.
The sidewall vent terminal shall not be installed closer than
10 feet from an inside corner of an L-shaped structure.
The sidewall vent cap should have a minimum clearance of
4 feet horizontally from and in no case above or below,
unless a 4 foot horizontal distance is maintained from
electric meters, gas meters, regulators and relief equipment.
Flue gas condensate can freeze on exterior walls or on the
vent cap. Frozen condensate on the vent cap can result in a
blocked flue condition. Some discoloration to exterior
building surfaces can be expected. Adjacent brick or
masonry surfaces should be protected with a rust resistant
sheet metal plate.
Power sidewall vent kits
The Power Sidewall Vent kit MUST be ordered from the
pool heater manufacturer. The part number for each kit is
listed by unit size. Each kit includes a flue adapter, an air
inlet cover, a powered sidewall fan/cap assembly, barometric
damper, control relay, proving switch and instructions for
proper installation. The outdoor vent kit, installed on the
pool heater as shipped from the factory, must be removed to
install the Power Sidewall Vent kit.

ƽ CAUTION
Pool heaters which are shut down or will not
operate may experience freezing due to
convective air flow into the equipment room.
If operated in cold climates, continuous
pump operation is recommended to help
prevent freezing of pool water. Proper freeze
protection must be provided. A pool heater
that is not in use in the winter season must
be properly drained and winterized. See the
Winterizing section of the EnergyRite Service
Manual.
The power directaire horizontal vent
system
The Power DirectAire Horizontal vent system requires the
installation of two pipes directly to the pool heater, one pipe for
flue products and one for combustion air. Both pipes are
installed horizontally with a sidewall termination point. Vent
connection is made directly to the pool heater. Flue products
are carried to the sidewall by a power sidewall cap/fan assembly.
A barometric damper is supplied with each DirectAire
Horizontal Vent kit and MUST be installed in the flue of each
unit. The barometric damper must be adjusted to maintain a
negative draft between 0.02 to 0.08 inches water when the power
sidewall vent cap is operating.

CAUTION
The Power Sidewall Vent kit is to be used
for 120 VAC applications ONLY.
