Spark Safety Device: Automatically shuts unit down when there is an abnormal spark at time
of ignition.
Flame Failure Device: Activated when burner flame fails. This prevents raw gas from being
released.
Overheat Switch: This device automatically cuts the gas off if the heater exceeds a
predetermined temperature. This is normally caused by an
obstruction in front of the louvers, or a blocked fan filter.
Fusible Links: Backs up the overheat switch. If the fusible link cuts the unit off, a
service call by an authorized person is required to replace the link.

–2 –
Overcurrent Prevention Device: This is a 3 amp. glass fuse found on P.C. board. Designed
to shut unit down in case of overcurrent. If fuse blows, all
indicator lamps will be “OFF”.
Power Outage Safety Device: This safety device cuts off gas passage and stops
operation.
Local and state codes must be adhered to prior to installation.
Rinnai is continually updating and improving products. Therefore, specifications are subject to change
without prior notice.
Thank you for purchasing a Rinnai gas forced flue heater.
Before using this product, please read this manual carefully to insure proper use of the product.
Please read the attached warranty thoroughly and keep it in a safe place.

Before using this product, please read this manual carefully to insure proper use of product.
1. The installation must conform with local codes or, in absence of local codes, the National Fuel Gas
Code, ANSI Z223.1 or the Canadian Installation Code, CAN/CGA-B149.
2. For information on gas type, see data plate on the appliance.
3. This heater must not be installed where curtains or other combustible materials could come into

4. This appliance is not designed to be built in.
5. If you move, check the gas type in the area where you are moving to. The local gas authority will be
able to advise on local regulations.
6. This heater discharges a large volume of warm air at low level to provide even heat distribution. If
the air in the room contains cooking vapor or cigarette smoke, and the heater is used on a carpet,
the surface of the carpet may become discolored. In addition, some nylon carpets contain dyes
which may be affected by the warm air flow. Some soft vinyl surfaces are also subject to distortion,
or discoloration by warm air. To prevent discoloration of carpets, etc., a mat should be placed under
the appliance, extending about 30" (750mm) in front of it.
