Key Features of the Rinnai 11i LPG

11 L/min Continuous-Flow Hot Water

The Rinnai 11i is designed to produce hot water as it is required rather than storing a large volume of heated water.

Rinnai specifies a maximum flow of 11 L/min, making the appliance suitable for a range of domestic and appropriate light-commercial hot-water applications. Actual flow depends on incoming water temperature, water pressure, selected outlet temperature and installation conditions.

LPG Gas Operation

This version of the Rinnai 11i is configured for LPG operation.

Rinnai also lists the 11i range in Natural Gas, LPG and BioLPG configurations, subject to the appropriate appliance configuration.

Low-NOx Gas Water Heating

The Rinnai 11i incorporates Low-NOx combustion technology, making it relevant to customers looking for modern LPG instantaneous water-heating equipment with reduced nitrogen oxide emissions.

Internal Wall-Mounted Installation

The Rinnai 11i is designed for internal wall-mounted installation and uses a room-sealed forced-flue system.

Its compact dimensions make it useful for installations where available internal space is limited.

Vertical Flue Kit

This product configuration is supplied with a Rinnai 11i vertical flue kit.

Rinnai identifies a Standard Vertical Flue Kit for the 11i, consisting of the appropriate adaptor and vertical roof-terminal components for the supported installation configuration.

The exact supplied components should always be checked against the product package and installation requirements before installation.
