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.

Follow all requirements in the General Venting section and
Sidewall Venting for venting flue products to the outdoors and
general installation instructions.
The Power DirectAire Horizontal vent system requires the
installation of two pipes directly to the pool heater, one pipe
Power Sidewall Kit 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
100169238
barometric damper is supplied with each DirectAire Horizontal
Vent kit and MUST be installed in the flue of each unit. The
100169239
barometric damper must be adjusted to maintain a negative
100169240
draft between 0.02 to 0.08 inches water when the power sidewall
vent cap is operating.

Installation & Operation Manual
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 Sidewall Vent kit is to be used
CAUTION
for 120 VAC applications ONLY.
