IMPORTANT
Framing
Prepare a suitable opening for the recess box
and the flashing system intended to be used
to ensure the cavity is weathertight.
Make sure there will be enough space to
run the pipe and electrical connections into
the box, and allow clearance at the top for
the water heater mounting bracket to slip
through.

Installation
When installing the recess box ensure it is
oriented so the sealing flange is against the
wall surface and the drainage slots are in the
lower most position.
The recess box can be secured using any of
the methods described below:
• Secured externally
• Secured using brick ties
• Secured internally through the rear wall
• Secured internally through a side wall
Secured externally
Use the 8 x 100 mm screws supplied to secure
the flashing collar and recess box to the wall
surface.
Use only the eight holes that are
provided. DO NOT attempt to screw or
nail through the sealing flange as this
may damage the frame.
Secured using brick ties
Secure a brick tie to the side walls of the
recess box with pop-rivets or screws.
