
This furnace discharges a large volume of warm air
next to the floor. Any particles in the air such as
cigarette smoke could cause discoloration in nylon
carpets containing dyes or vinyl surfaces.

Rinnai suggests that a dedicated electrical circuit
with a 120VAC, 60 Hz, 10 amp power source be
used.

A test plug is provided for testing of manifold
differential pressure. It is located on the modulating
gas valve.

If you move to a different location, 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 furnace, 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.

The furnace 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).

The furnace must be isolated from the gas supply
piping system by closing its equipment shutoff 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 or other combustible material
other than wood, then the furnace must be installed
on a metal or wood panel extending the full width
and depth of the furnace.

This furnace is only for use with the type of gas
indicated on the rating plate. This furnace is not
convertible for use with other gases unless a certified
kit is used. If conversion of the unit is needed,
conversions must be performed by a qualified
service provider at the owner's expense.

The furnace 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
section "6. Maintenance" for adequate combustion
and ventilation air.

This furnace is not designed to be built in.

DO NOT connect this furnace to a chimney flue
serving a separate solid-fuel burning appliance.

DO NOT obstruct the flow of combustion and
ventilation air.
