CLEARANCES
The Aquastar 125 X is design certified for installation on a
combustible wall and for installation in an alcove with the
minimum clearances to combustible and non -combustible
construction listed below
A. Top 12 inches ( 305 mm)
B. Front Open
C. Back 0 inches
D. Sides 4 inch (102mm)
E. Bottom 12 inches (306 mm)
Clearance from vent is dependent upon the clearance
rating of the venting material used. For example: type B-1
vent is approved for 1 inch clearance, B-2 vent for 2 inch,
etc.
Note: Minimum clearance to combustible materials should
not be less than 6" for single wall flue pipe. Note that this
clearance can be reduced if combustible material are
protected as per table VI of the National fuel Gas Code or
if Type B gas vent is used.
MOUNTING INSTALLATION
The Aquastar 125 X is design certified for mounting on a
wall.
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.
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).

The incandescent particle tray (shipped loose in the carton
with the water heater) must be attached at the bottom of
the water heater front cover at the time of installation. Use
the screws provided. See figure 2
VENTING
Vent pipe connection. WARNING: Do not reduce the
vent pipe size.
This appliance must be vented to the outside following all
local ordinances and specifications for installing a gas
appliance vent or chimney. The venting system must be
designed and constructed so as to develop a positive flow
adequate to remove flue gasses to the outdoors. Minimum
vent size must be 5". Minimum vent height must be 6
feet, provided there are no elbows. Termination of the
vent must be 2 feet above any obstruction within a 10
foot radius of the vent pipe. Consult your gas utility
or National Gas Fuel Code if vent will have elbows or
share venting with another appliance. The vent
connector should have as much vertical rise as
possible (minimum 12") before any horizontal run.
Optional powervent available in order to sidewall vent.
Contact your local dealer. The appliance must be located
as close as practicable to a chimney or vent. The vent
pipe sections must be secured to each other with sheet
metal screws. Keep in mind the minimum clearance from
the top of your heater. Remember also that single wall
vent pipe connectors require a 6 inch clearance from
combustibles. National Fuel Gas Code specifies double
wall — Type "B" — vent pipe be used in cold climates and
for gas vents running through attics. We consider double
wall vent pipe preferable in all circumstances. Any vent
section greater than 45 degrees from vertical is considered
horizontal. Horizontal sections of vent connectors must
slope upwards at least 1/4 inch for every foot of its
horizontal length. Keep the horizontal section short and
avoid too many elbows.
WARNING
Note: The burners of an instantaneous "on demand" water
heater such as the AquaStar are only on at the time that
hot water is actually being used, the venting stack is
WALL STUDS
therefore cold except for the short durations when hot water
is being used, it is therefore very important that the venting
and air supply be adequate to provide a good positive

draft as soon as the burners turn on. See venting guide
on back page.
The AquaStar 125X instantaneous water heaters have
built-in draft diverters and are designed for indoor
installation only. The draft diverter outlet must be connected
1" X 4"
to a clear, unobstructed vent of the same size, or larger.
