Compact 2 Installation Guide: 11817-D 04-15
Flueing options
The below options detail the most common types of flue installations. If you have an
installation that varies from those below, please contact Rinnai.
Flue component
- Flue cowl (R1760-2)
Masonry without a flexiliner flue
For installations into a masonry cavity where
the chimney has been swept, checked for
soundness and ability to achieve a good draw.
Masonry with flexiliner flue
For installations into a masonry cavity where
a Rinnai aluminium flue is required to ensure
optimum performance of the appliance.
Flue components
- Flexiliner flue kit (R1758) 3.6 m
If flueing exceeds 3.6 m add:
- Flexiliner flue extension (R1761)
Inbuilt mock chimney direct and offset
For installations into a combustible opening
with a zero clearance box, where the flue runs
vertically in-wall.
A: Flue component
- Zero clearance flue kit (R1762Z)
B: Flue components
- Zero clearance flue kit (R1762Z)
- 45 ° bend kit x 2 (R1764)
If flueing exceeds 3.6 m add the
galvanised or stainless steel flue
extension (R1763Z, R1763SS).
Inbuilt mock chimney offset wall penetration
For installations into a combustible opening
with a zero clearance box. Flue runs in-wall,
then penetrates the building before terminating
vertically.
Typically used in multi-storey dwellings where
the fire is installed on the ground floor.
Flue components
- Zero clearance flue kit (R1762Z)
- Wall penetration kit (R1766)
If flueing exceeds 3.6 m add the
galvanised or stainless steel flue
extension (R1763Z, R1763SS).
Masonry installations
Rinnai recommends the use of a flexiliner flue (Ø 100 mm) as it ensures optimum performance of the
appliance. Installation without a flexiliner flue is permitted as long as the chimney has been swept,
checked for soundness and ability to achieve a good draw.
Mock chimney flueing
A Rinnai zero clearance box and flue kit are mandatory for installations into a combustible opening.
Minimum flue length - 3.6 m
This is required to ensure adequate draw and to prevent spill-back of combustion products, which can
cause the safety sensors to shut down the fire. The minimum flue length before any bends or offsets is
1.2 m (or one length of flue). The minimum vertical flue length is 3.6 m or three lengths of flue.
Maximum flue length - 8 m
Rinnai recommends a maximum flue length of 8m with a maximum of two 45 ° bends.
