Flueing options
The gas pressures of the Linear are factory set for short flue installations, as pictured below. All
other installations, greater than 3 m in length, are long flue installations and will require a dip switch
change, refer commissioning sheet.

For lowest cost, optimal performance, ease of installation and servicing, Rinnai recommend short
flue installations are considered before all other options.
Maximum flue length and number of bends
•
Maximum flue length
•
Maximum number of 90 ° bends = three
For every 90 ° bend, the overall length must be reduced by 1 m. For example, if an installation has
three 90 ° bends, the maximum flue length can be 5.5 m.
The Linear flue installation differs to Arriva and Evolve power flue installations as the elbow
component of the flue adapter (LSFKIT01)
300 mm of straight flue before any bends
300 mm minimum of straight flue is required before any bends. This is required due to heat
produced from the initial section of the flue. The LSFKIT01 has this built in, and the LSFEXTKIT01
(flue transition extension) is used after the ASPDFK before any bends.
Side direct, side extended, side and back flueing
Side direct through-the-wall flueing for walls up to 385 mm thick.
Flue can be extended if the wall thickness is greater than 385 mm
by using additional lengths of flue pipe, and flue can be directed
behind using the flue transition extension and bend kit. Refer to
p.40 for more information.
Flue components used:
•
Direct flue kit (ASPDFK)
•
Flue transition extension (LSFEXTKIT01)
•
Flue pipes (ESPIPE900)
•
45° bends (ESBEND) to change direction
Flue terminal section is reusable when making the flue longer.
