Component/Clearance Specifications

•The letters “RCE” indicates this is a “Rinnai Convection Export” heater.

•The numbers “510 & 824” indicate the model number of heater.

•The letter “T” indicates duel timers on 824 model, no “T” indicates single timer on 510 model.

•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

Gas

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.
