Air Requirements

Vent Requirements

A vent pipe extension of the same size must be
connected to the draft hood and extended at least
two (2) feet above any obstacle within a 10 foot radius
of the vent. The vent should then be capped with an
approved weather cap.
NOTE
Do not alter the heater draft hood in any way; it
has been designed by the manufacturer and
approved by A.G.A. for maximum efficiency.
To insure efficient venting, use a 45° elbow for
horizontal installation when attaching the vent pipe
to the draft hood.

per Foot
Air Requirements
When a heater is installed indoors, two air openings
must be provided. Ideally one opening should be
placed at the bottom and one at the top of the room
to allow for a free flow of air. If other gas
appliances are installed in the same room, you must
check to see that they have been provided with the
proper size openings, otherwise they may use the air
intended for your pool heater.
