The Rinnai internal flueing system is highly versatile and makes installation of an internal water heater simple and convenient.

The flueing for internal water heaters is a coaxial design. It is manufactured from an aluminium alloy inner flue pipe to discharge product of combustion and a thermoplastic outer pipe for air supply to the appliance. The water heater is a room sealed appliance.

Note: Each Rinnai heater is flued individually.

As it is fan assisted, the heater can be flued vertically, horizontally or any combination of both, to a maximum of 9 metres and 3 x 90 degree bends.

Horizontal flueing can be used as a direct wall flue or extended from another internal wall.

Vertical flueing is used when the water heater needs to be flued vertically through the roof.

A condensate trap is required when vertical flue exceeds 1.5 metres.

Rinnai HD internal water heaters are classified as ‘room sealed’ appliances. Flue systems must be installed in accordance with Rinnai Installation instructions (supplied with flue terminals), local gas fitting regulations, municipal building codes, AS5601 and all other relevant statutory regulations.

The flue terminal clearances in AS5601 / AG601 do not apply to the HD200e and HD250e heaters installed side by side. The appliance are AGA certified to be located Side by side, for both internal an external models.

Discuss with your Rinnai Commercial representative for further details.

Note: Only Rinnai flueing systems can be used with internal water heaters. Non-Rinnai flueing systems are not certified and will not be covered under warranty.
