lines, valves, and electricity; Knowledge of
applicable national, state, and local codes;
Installing venting through a wall or roof; and
training in installation of tankless water

When installing the water heater, follow these
guidelines:
•
This water heater is NOT certified for
installation in manufactured (mobile) homes.
•
This water heater is suitable for combination
water heating and space heating and not
suitable for space heating applications only.
•
The installation must conform with local
codes or, in the absence of local codes, with
the National Fuel Gas Code, ANSI Z223.1/
NFPA 54, and/or CSA B149.1, Natural Gas
and Propane Installation Code.
Rinnai Tankless Water Heater Installation and Operation Manual
•
The appliance, when installed, must be
electrically grounded in accordance with
local codes or, in the absence of local
codes, with the National Electrical Code,
ANSI/NFPA 70, and/or the CSA C22.1,
Canadian Electrical Code, Part 1.
•
The appliance and its main gas valve must
be disconnected from the gas supply piping
system during any pressure testing of that
system at test pressures in excess of 1/2
psi (3.5 kPa) (13.84 in W.C.). The appliance
must be isolated from the gas supply piping
system by closing its individual manual
shutoff valve during any pressure testing of
the gas supplying system at test pressure
equal to or less than ½ psi (3.5 kPa) (13.84
in W.C.).
•
You must follow the installation instructions
and those in section "4.5 Vent the Water
Heater" for adequate combustion air and
exhaust.
•
If a water heater is installed in a closed
water supply system, such as one having a
backflow preventer in the cold water supply
line, means shall be provided to control
thermal expansion. Contact the water
supplier or local plumbing inspector on how
to control thermal expansion.
•
Should overheating occur or the gas supply
fail to shut off, turn off the manual gas
control valve to the appliance.
(En cas de surchauffe ou si l'alimentation
en gaz ne s'arrête pas, fermez
manuellement le robinet d'arrêt de
l'admission de gaz.)
•
Combustion air must be free of chemicals,
such as chlorine or bleach, that produce
fumes. These fumes can damage
components and reduce the life of your
appliance.
DO NOT
•
DO NOT install the water heater outdoors
without the Rinnai outdoor vent cap (Part #
RXOVC).
•
DO NOT install the water heater indoors
with the Rinnai outdoor vent cap (Part #
RXOVC)
•
DO NOT install the water heater in an area
where water leakage of the unit or
connections will result in damage to the
area adjacent to the appliance or to lower
floors of the structure. When such locations
cannot be avoided, it is recommended that
a suitable drain pan, adequately drained, be
installed under the water heater. The pan
must not restrict intake air flow.
•
DO NOT install the water heater in an area
with negative air pressure.
•
DO NOT obstruct the flow of combustion
and ventilation air.
•
DO NOT use chemically treated water (i.e.
chlorinated water or salt water for pools or
spas) in the appliance.
•
DO NOT use substitute parts that are not
authorized for this appliance.
