Ensure the vent and air piping and the combustion air supply comply with these instructions regarding vent system, air system, and combustion air quality. Inspect finished vent and air piping thoroughly to ensure all are airtight and comply with the instructions provided and with all requirements of applicable codes. Failure to provide a properly installed vent and air system may cause severe personal injury or death. Use only the material listed in Rinnai's vent documentation for vent pipe, and fittings. Failure to comply could result in severe personal injury, death or substantial property damage. Installation must comply with local requirements and with the National Fuel Gas Code, ANSI Z223.1 for U.S installations or CSA B 149.1 for Canadian installations. For closet and alcove installation, CPVC material (instead of PVC) must be used in a closet/alcove structure. Failure to follow this warning could result in fire, personal injury, or death. All vent pipes must be connected and properly supported, and the exhaust must be pitched a minimum of a 1/4” inch per foot back to the boiler (to allow drainage of condensate). Please refer to the venting manufacturer's manual to see if a larger pitch is required for specific venting sytems. For the Room Air System, combustion air piping from the outside MUST BE used. Use of combustion air from indoor rooms using louvers, plenums, or any other devices is not authorized. See the Rinnai Boiler Applications Manual for further information on venting. ! iii! Installation 6.7.6 Combustion air and vent piping lengths. In the table below you find the maximum equivalent pipe length of the vent/air system based on 3" diameter. These lengths are for single pipe (room air), twin pipe, and concentric venting systems. Boiler type 3” Max Vent equivalent length 3” Max Air equivalent length E75 100 feet 100 feet E110 100 feet 100 feet Equivalent vent length table 9 Calculation of equivalent length vent system Choose the vent type and fill out the corresponding table. * When determining equivalent combustion air and vent length, add 6 feet for each 90° elbow, 3 feet for each 45° elbow, 5 feet for the concentric terminal in the Parallel System, and 2 feet for the concentric terminal in the Concentric System .

Installation & Servicing Instructions Rinnai E-Series 6.7.7 Calculation of compensation factor The compensation factor eliminates or reduces the natural effect of derate of maximum input caused by the resistance of the vent system and/or the impact of the altitude. 1.

Compensation factor altitude CP(A) table 11 Any application or installation above 10,000 must be reviewed by Rinnai's NOTICE Engineering group. This is to ensure the product is installed and the overall system is designed properly and that the units are commisioned properly. Not involving of Rinnai's Engineering group would result in no support of the product and no warranty. 3. Calculate the Compensation Factor Total CF(T): CF(T) = CF(V) + CF(A) The result is the setting for Parameter 73. Change parameter 73 according to this result. See Chapter 10.1 how to change parameters. Example of calculation: WARNING E110 Eq. lenth vent system (taken from previous example) 46 ft CF(V) = 6 Altitude 7,200ft CF(A) = 42 + CF(T) = 48 Parameter setting (Par. 73) = 48 Do not overcompensate the boiler by setting a higher value than calculated, otherwise the boiler could be seriously damaged. Installation Installation & Servicing Instructions Rinnai E-Series 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.
