MOUNTING INSTALLATION
The Aquastar 125 B “S” is design certified for mounting on
a wall.
Secure the two L shaped hooks provided with the heater to
a wall surface. Place them 13 ¼ inches apart as shown in
Fig 1. Do not install this appliance on a carpeted wall or
over floor covering which is combustible, such as carpet.
The heater must be mounted on a wall using appropriate
anchoring materials. If wall is a stud wall sheathed with
plasterboard, it is recommended that support board(s),
either 1x4’s or 1/2" (minimum) plywood first be attached
across a pair of studs and then the heater should be
attached to the support boards. See Fig 1.
Expansion and contraction of piping due to changing water
temperature in the pipes imparts movement to the heater
which, if mounted directly to a brittle, friable board, such as
plasterboard, can cause failure of mounting.
In earthquake-prone zones, BBTNA recommends that
installers use a large washer and lag screw through the
existing holes used to hang the heater to affix the upper
third of the heater to the mounting board. To affix the lower
third of the heater, BBTNA recommends that two new holes
be drilled in the heater’s frame, each one 16 inches below
the top two holes, and that washers and lag screws be used
to secure the lower portion of the heater to a spacing board.
Before installing the unit, be certain you have the correct
heater for your type of Gas – Propane or Natural Gas.
Identification labels are found on the shipping box, and on
the rating plate which is located on the right side panel of
the cover. Also, each burner orifice is stamped with a number
(79 for LPG and 120 for Natural Gas).
