•The letter “A” indicates this is an American version.
•The “FC” indicates Fan Convertor Heater.
•These units are not suitable for use in bathrooms or bedrooms. Vent-free heaters installed in
bathrooms and/or bedrooms must be wall mounted. This product can not be wall mount at the
present time.
•Product warranty –3 year parts, no labor.
Ledger Plate Explanation & Warranty

1. Convection fan starts, drawing air in through
the back of the cabinet and across the heat
exchanger / burner chamber and out into the
space. The PCB verifies fan rotation.
2. Once the fan is running at the proper speed,
spark ignition begins.
3. After spark begins, the gas valve solenoids
open allowing gas into the burner.
4. Ignition occurs and flame develops across the
burner.
5. The PCB will verify flame with thermocouples
and turn off the sparker.
6. Warm air then begins to flow into the space.
7. PCB will determine gas input and fan speed
settings based on the room temperature
measurement from the room thermistor.
8. When thermostat set point is reached the gas
valve solenoids close. The combustion fan will
continue to run to cool down the unit.
9. When the room temperature drops below the
set point, the process will start again.

Usage

Usage
Gas
Usage Continuous gas usage but at much lower levels
•With on/off single stage operation, gas usage
can be high due to alternating periods between
maximum flame and no flame at all
•The Fan Convector modulating technology has the
ability to replace only the heat escaping the
structure by continuously operating at heating levels
based on the demand at that moment
•This results in different layers of temperatures
throughout the structure leading to a less than
comfortable living environment
•This leads to lower gas usage and higher levels of comfort.
Modulating Technology
Note; if the “Auto Off” function is not selected the unit will
run continuously no matter what the room temperature is.

•Do not install this appliance above 2,000ft.
•Do not block the warm air discharge.
•Do not allow anyone to sleep directly in front of the appliance.
•Do not insert items into the louvers.
•Do not place clothing or other flammable material on or near the appliance
•Do not spray aerosols near the appliance while it is operating. Most aerosols contain butane gas
which is flammable.
•Do not install this appliance in areas where spray painting or plating is taking place, or in places such
as hair salons where there may be large amounts of dust, chemical residue, or debris. Using the
appliance in such areas may result in strong odors or irritated eyes and sinuses.
•Do not sit on the appliance.
Installation Instructions

•Do not unplug the appliance while it is operating or while the fan is on.
•Do not use a plug in type timer with this appliance.
•Do not install in a windy area such as facing a window or a door leading to the outside.
•Do not recess this appliance or mount it directly in a wall
•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.
•This appliance discharges a large volume of warm air next to the floor. Any particles in the air
such as cigarette smoke, lint, dust, or debris 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.
•The flow of combustion and ventilation air shall not be obstructed.
•Note that in some regions, an unvented gas heater will increase the amount of humidity in the
room.
