General
The manifold gas pressure is preset at the factory. It is
computer controlled and should not need adjustment.
Maintain proper space for servicing. Install the unit so
that it can be connected or removed easily. Refer to pg.
6 for proper clearances.
The electrical connection requires a means of disconnec-
tion, to terminate power to the water heater for servicing
and safety purposes.
If you will be installing the unit in a contaminated area
with a high level of dust, sand, flour, aerosols or other
contaminants/chemicals, they can become airborne and
enter and build up within the fan and burner caus-
ing damage to the unit. In those environments (e.g.
residential or commercial laundry facilities, hair salons,
pet salons, chemical plants etc.), please purchase the
optional direct-vent conversion kit and convert the 910 to
a sealed combustion unit. Direct venting allows the 910
to draw fresh intake air from the outside. The warranty
will not cover damage caused to the unit due to instal-
lation in a contaminated environment that has not been
converted using the direct-vent conversion kit.
Particles from flour, aerosols, and other contaminants
may clog the air vent or reduce the functions of the rotat-
ing fan and cause improper burning of the gas. Regularly
ensure that the area around the unit is dust- or debris-
free; regular maintenance is recommended for these
types of environment.
Do not install the unit where the exhaust vent is pointing
into any opening in a building or where the noise may
disturb your neighbors. Make sure the vent termination
meets the required distance by local code from any
doorway or opening to prevent exhaust from entering a
building (refer to pg. 10).
Included Accessories
Check that the installation manual, the communication
cable, and the product registration card are included with

Warning For Installations
FOR YOUR SAFETY, READ
BEFORE INSTALLATION
Do not install the heater
where water, debris or flam-
mable vapors may get into
the flue terminal. This may
cause damage to the heater
and void the warranty. Do not have the vent ter-
minal pointing toward any
opening into a building. Do
not locate your heater in a
pit or location where gas
and water can accumulate.
Do not install next to a dryer
or any source of airborne
debris that can be trapped
inside the combustion
chamber, unless the system
is direct vented.
