6.7.8 Room Air System (indoor combustion air) When using indoor air, Rinnai strongly recommends the use of an indoor air filter, P/N 808000025. This boiler requires adequate combustion air for ventilation and dilution of flue gases. Failure to provide adequate combustion air can result in unit failure, fire, explosion, serious bodily injury or death. Use the following methods to ensure adequate combustion air is available for correct and safe operation of this water heater.
Confined Space: (Small Room, Closet, Alcove, Utility Room, Etc.) A confined space is defined in the NFPA #54 as "a space whose volume is less than 50 cubic feet per 1000 Btu/hr (4.8 m3 per kW per hour) of the aggregate input rating of all appliances installed in that space." A confined space must have two combustion air openings.
Using Indoor Air For Combustion When using air from other room(s) in the building, the total volume of the room(s) must be of adequate volume (Greater than 50 cubic feet per 1000 Btu/hr). Each Combustion air opening must have at least one square inch of free area for each 1000 Btuh, but not less than 100 square inches each. Using Outdoor Air For Combustion Outdoor air can be provided to a confined space through two permanent openings, one commencing within 12 in.

9 Starting up: Filling and de-aerating the boiler and installation ! CAUTION i NOTICE i NOTICE ! WARNING CAUTION Observe the following rules of safety: - All work on the unit must take place in a dry environment. - Rinnai units may never be in operation without their housing, except in connection with maintenance or adjustments (see Chapter 12 and 13). - Never allow electrical or electronic components to come into contact with water.
Freeze protection Freeze protection for new or existing systems must use glycol that is specially formulated for this purpose. This includes inhibitors, which prevent the glycol from attack the metallic components. This should be for multi-metallic components. Make certain to check that the system fluid is correct for the glycol concentration and inhibitor level. The system should be tested at least once a year and as recommended by the producer of the glycol solution.
i NOTICE It can take a while before all air has disappeared from a filled installation. Especially in the first week noises may be heard which indicate the presence of air. The automatic air vent in the boiler will remove this air, which means the water pressure can reduce during this period and therefore topping off with water will have to be done.
FOR YOUR SAFETY READ BEFORE OPERATING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance does not have a pilot. It is equipped with an ignition device which automatically lights the burner. Do NOT try to light the burner by hand. B. BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
