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.

Securing options
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
Secured to the wall surface via the eight screw
holes provided in the flange of the recess box
using suitable fasteners.
Secured using brick ties
Secure a brick tie to the side walls of the
recess box with pop-rivets or screws.
As the brickwork is being laid, use the
attached brick ties to secure the recess box
into the brick courses. Use two brick ties
per side, one near the top, and one near the
bottom.
Secured internally - rear wall
Install two nogs between the wall studs. These
are to be centered at 130 mm from the top and
bottom of the opening. Secure the recess box
through the rear using suitable fasteners.
