System Installation and Service Instructions
Page 5
Wall Mounting:
1. Note the location of the mounting holes on the back of the Generator. The
screws must set directly into studs or equivalent supports. Drill pilot holes on 12"
centers and install the two #10 1-1/2 inch screws provided. See Diagram 6.
2. Carefully hang the Generator on two screws. Tighten the screws. Replace the
front cover. Secure the front cover with six (6) screws.
3. Mounting should be level.
Floor Mounting:
1. In general the width of the unit allows it to sit on a shelf, across the ceiling joists
or on a floor. The Generator must be restrained from moving. Normally the piping
will provide adequate support. If not, additional support must be provided.
2. All floor installed Generators must have provision for routine draining of the
tank.
3. Mounting should be level.

SECTION 4: PLUMBING INSTRUCTIONS
Run 3/8 inch copper tube between the nearest cold water line and the WATER INLET fitting on the Generator.
Locate a shut-off valve near the Generator. Connect this line to the Generator with a 3/8" compression adapter.
When tightening this fitting always use two wrenches so there will be no strain on the water inlet valve.
SEE DIAGRAMS 1 (PREFERRED INSTALLATION, 7 & 8
SECTION 4A: INSTALL THE WATER LINE
IMPORTANT
Maximum recommend input water pressure not to
exceed 100 PSI
IMPORTANT
The Generator will not operate
properly, unless it is mounted level
with its arrows pointed up.
If the generator is mounted in a
place difficult for the homeowner to
access, the water supply shut-off
valve should be located where it can
be quickly accessed in an
emergency.
Do not use a saddle valve or saddle
fitting for the water supply shut-off
valve. Flush water supply line
before final hookup.
Do not connect the overpressure
device output into the steam line.
Do not connect the drain valve into
the steam line.
