Rinnai 17i LPG gas water heater

The Rinnai 17i LPG Gas Water Heater is an internal, room-sealed, instantaneous LPG water heater designed to provide continuous hot water for domestic, commercial and multipoint applications.

The Rinnai 17i combines Low-NOx combustion technology, electronic ignition, internal wall-mounted installation and continuous-flow water heating in a compact appliance. The supplied vertical flue kit provides the flue components required for the applicable installation configuration.

With a maximum flow of up to 16.3 litres per minute at a 25°C temperature rise, the Rinnai 17i is suited to applications where hot-water demand varies and a conventional storage cylinder is not the preferred configuration.

Rinnai 17i LPG Water Heater Performance

The Rinnai 17i is designed to heat water as it passes through the appliance rather than storing a fixed volume of hot water.

Its published maximum flow at a 25°C temperature rise is approximately 16.3 L/min. Actual hot-water flow depends on factors including incoming cold-water temperature, water pressure, selected outlet temperature and installation conditions.

Flow Performance

This makes the Rinnai 17i a strong option for customers searching for a 17 L/min-class LPG water heater, while the manufacturer’s detailed specification should be used when sizing the appliance.

36 kW-Class LPG Gas Water Heater

The Rinnai 17i LPG model has a maximum gross gas input of approximately 36.0 kW, with a net input of approximately 33.1 kW and an output of approximately 28.4 kW under the specified operating conditions.

For SEO and product comparison purposes, it is commonly described as a 36 kW LPG water heater or 17 L/min-class LPG water heater.

The exact operating performance should always be assessed against the installation’s gas supply, water pressure, incoming water temperature and required temperature rise.

Low-NOx LPG Water Heating

The Rinnai 17i incorporates Low-NOx combustion technology designed to reduce nitrogen oxide emissions from the combustion process.

This makes Low-NOx terminology an important product attribute for customers searching for modern LPG gas water heaters and for installers comparing appliances against applicable European requirements.

Always verify the applicable national requirements and the current manufacturer’s documentation before installation.

Internal Room-Sealed Design

The Rinnai 17i is designed for internal wall-mounted installation and uses a forced room-sealed flue arrangement.

The room-sealed design separates combustion air and flue gases from the occupied space through the appropriate flue system.

This configuration can make the appliance suitable for a range of internal installations when the appliance, flue arrangement and local regulations are correctly specified.

Vertical Flue Kit

This product configuration is supplied with a vertical flue kit.

Before ordering, customers should confirm that the supplied flue components match their intended installation configuration. Flue routing, terminal position, maximum flue length and any required bends must comply with the current Rinnai installation instructions and applicable national regulations.

Do not modify or install the flue system outside the manufacturer’s approved configuration.

Technical Specifications

Typical Applications

The Rinnai 17i LPG gas water heater can be considered for suitable:

• Houses and apartments
• Multi-point domestic hot-water systems
• Holiday properties
• Hospitality applications
• Restaurants and cafés
• Small commercial premises
• Offices
• Rental properties
• Temporary or emergency hot-water installations
• LPG-powered properties without mains natural gas
• Replacement projects for compatible older instantaneous water heaters

The correct appliance size should be determined from the number of outlets, simultaneous hot-water demand, incoming water temperature, desired temperature rise, water pressure and available LPG supply.

Rinnai 17i for Domestic Hot Water

For homes requiring hot water from multiple outlets, an instantaneous LPG water heater can provide hot water when demand occurs rather than relying on a conventional storage tank.

The Rinnai 17i can therefore be considered where an LPG-powered continuous-flow system matches the property’s hot-water requirements.

Actual performance depends on the installation and operating conditions.

Rinnai 17i for Commercial Applications

The Rinnai 17i may also be suitable for smaller commercial hot-water requirements where its flow and output meet the calculated demand.

For larger commercial installations, the required water-heating capacity should be calculated before selecting equipment. Larger Rinnai commercial models and multiple-unit configurations may be more appropriate for higher-demand applications.

BioLPG and Alternative Fuel Compatibility

Rinnai markets applicable 17i configurations as BioLPG-ready. Fuel compatibility should always be confirmed against the exact appliance configuration, current manufacturer documentation and the fuel specification available at the installation location.

Do not assume that every LPG fuel or blend is automatically approved simply because an appliance is LPG-compatible.

Installation Requirements

The Rinnai 17i is a gas appliance and should be installed and commissioned by an appropriately qualified professional.

Installation should follow:

• Current Rinnai installation instructions
• Applicable European requirements
• Local and national gas regulations
• Building regulations
• Flue requirements
• LPG supply requirements
• Water-pressure requirements
• Electrical requirements
• Ventilation and clearance requirements where applicable

The installer should verify the gas type, gas pressure, water supply, flue route and terminal location before commissioning.
