Installation of this water heater is permitted within a covered area open on at least two sides, if its flue terminal
is located to ensure a free flow of air across it is achieved.
AS/NZS 5601.1 also allows the installation of
a continuous flow gas water heater within a
covered area open on one side only if the flue
terminal is within 500 mm of the opening, is
discharging in the direction of the opening,
there are no openings into the building along
the wall within the 500 mm distance and the
terminal is located to ensure a free flow of air
across it is achieved.
