Installation - Rinnai I Series Instruction Manual

3.0 Installation

This section is intended for the Installer. A trained and qualified professional must install the appliance, inspect
it, and leak test the boiler before use. The warranty will be voided due to any improper installation. The trained
and qualified professional should have skills such as: Gas sizing; Connecting gas lines, water lines, valves, and
electricity; Knowledge of applicable national and local codes; Installing venting through a wall or roof; and training in
installation of condensing boilers.
The appliance and its main gas valve must be disconnected from the gas supply piping system during any
pressure testing of the system at test pressures in excess of 3.5 kPa. For system testing at pressures less than
or equal to 3.5 kPa, the appliance must be isolated from the gas supply piping by closing its individual manual
shutoff valve.
The appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence
of local codes, with the AS/NZS3000 standards.
Ensure the wall is of sufficient strength to support the weight of the boiler, piping and any other components
needed for installation; if it is not, please reinforce the wall as appropriate.
Operating limits of the boiler:
Maximum boiler set point temperature
Maximum operating pressure
Maximum allowable working temperature
Maximum allowable working pressure
DO NOT install the boiler in an area where water leakage of the unit or connections will result in damage to the area
adjacent to the appliance or to lower floors of the structure. When such locations cannot be avoided, it is
recommended that a suitable drain tray, adequately drained, be installed under the boiler. The tray must not restrict
combustion airflow.
DO NOT install the boiler in an area with negative air pressure.
DO NOT obstruct the flow of combustion and ventilation air.
DO NOT use substitute parts that are not authorized for this boiler.
DO NOT install the boiler on areas with carpet flooring.
