CO-AXIAL FLUEING FOR INTERNAL MODELS

The Rinnai Continuous Flow Flueing system must be installed in accordance with the instructions supplied with

the flue terminal. Non Rinnai flueing systems MUST NOT be used. For all further information on Internal Flueing,

please refer to separate Flueing manual supplied with Flueing components.

Installations can consist of both horizontal and vertical runs to a

maximum of 9 metres with a maximum of three 90° bends.

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 Co-axial 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 water 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 the flue terminals), local gas

fitting regulations, municipal building codes, AS/NZS 5601 and all other

relevant statutory regulations.

The flue terminal clearances AS/NZS 5601 DO NOT apply to the HD200e

and HD250e heaters installed side by side.

These appliance are AGA certified to be located side by side, for both

internal and external models.

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.

NOTE

For Internal (FFU) models only
