Installation Instructions
• A qualified service technician should install the
appliance and inspect it before use.
• If you move, check the gas type in your new area. The
local gas authority will be able to advise on local
regulations.
• 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
, or the Natural Gas and
Propane Installation Code, CSA B149.1 .
• A manufactured home (USA only) or mobile home
OEM installation must conform with the Manufactured
Home Construction and Safety Standard, Title 24 CFR,
Part 3280
, or, when such a standard is not applicable,
the standard for Manufactured Home Installations,
ANSI Z225.1
, or the standard for Gas Equipped
Recreational Vehicles and Mobile Housing, CSA
Z240.4
.
• 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
, or the Canadian Electrical
Code, CSA C22.1.
• Appliance input ratings are based on sea level
operation and need not be changed for operation up to
2000 ft (610 m) elevation. For operation at elevations
above 2000 ft (610 m), follow the procedure in the
section, Adjust Gas Pressure Settings.
• The appliance and its appliance 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).
• The appliance must be isolated from the gas supply
piping system by closing its equipment shut off valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 psi
(3.5 kPa).
• If the flooring is carpet, tile, or other combustible
material other than wood, then the appliance must be
installed on a metal or wood panel extending the full
width and depth of the appliance.
• Rinnai suggests that a dedicated electrical circuit with
a 120V AC, 60 Hz, 10 amp power source be used.
• This appliance discharges a large volume of warm air
next to the floor. Any particles in the air such as
cigarette smoke could cause discoloration in carpet.
The warm air flow could discolor nylon carpets
containing dyes or vinyl surfaces. To prevent
discoloration of the floor covering a mat may be placed
under the appliance which extends about 30 inches
(750 mm) in front of it. (Wood is included in the
shipping container that can be cut to size and used if
needed.)
• This appliance is not designed to built in.
• This appliance is only for use with the type of gas
indicated on the rating plate. This appliance is not
convertible for use with other gases unless a certified
kit is used. If a conversion of the unit is needed,
conversions must be performed by a qualified service
provider at the owner’s expense.
•
Follow the Adjust Gas Pressure Settings (page 28)
and confirm that the correct code is used for your
gas type and altitude.
• This appliance must not be connected to a chimney
flue serving a separate solid-fuel burning appliance.
• Two 1/8 in test plugs are provided for testing of
manifold differential pressure. They are located on the
modulating gas valve and on the burner manifold.
• The appliance should be correctly sized for the space it
is required to heat. It is recommended that an industry
standard BTU Heat Loss Calculation be conducted to
determine the proper sizing.
• Follow the installations instructions and those in Care
and Maintenance
for adequate combustion and
ventilation air.
• The flow of combustion
and ventilation air shall
not be obstructed.
• Locate the heater
where outdoor air does
not affect the room air
thermistor. Otherwise,
the sensible
temperature control
feature will be affected.
• Clearances to access
the appliance during
servicing are 2 inches
(50 mm) from the
sides, 40 inches (1 m)
from the front, and the
area shown above the
appliance in the
picture.
