MOUNTING INSTALLATION
The Aquastar 125FX is design certified for mounting on a
wall.
Secure the two L shaped hooks, which are provided with
heater, to a wall surface. Place them 13 ¼” apart as shown
in Fig 2.
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 2.
NOTE: Additionally the 125FX should be spaced away
from any combustible wall surface to provide the
necessary clearance that the venting material specifies
must be maintained between the vent pipe and a
combustible surface. See VENTING section. Also, review
the FXHOOD horizontal vent terminator instruction sheet
(provided with the FXHOOD) prior to installation.
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.
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.
