OUTDOOR INSTALLATION
The water heater is to be installed at
ground level on a concrete or brick
plinth (fire proof base) and must stand
vertically upright with the back of the
water heater against an external wall
or alternatively against a fireproof
screen extending at least 500mm
above, below and either side of the flue
terminal. Failure to observe this
precaution can cause problems in high
wind areas. A secondary flue is not
required.
For outdoor models the following
distances should be observed:
• At least 500mm between the top of
the water heater and the eaves.
• At least 500mm (265) or 1500mm
(275) horizontally between the
water heater and the edge of any
opening into the building.
• At least 1000mm (265) or 1500mm
(275) vertically from the top of the
water heater to the bottom edge of
an openable window.
• At least 500mm measured
horizontally along the wall between
the water heater and a return wall
or external corner.
• At least 500mm clear of any
combustibles.
