Down And Out Flue Assembly - Rinnai Linear Series Flue Installation Manual

Down and out flue assembly

The down and out flue allows for
the adaption flue component to face
downwards, and for the flue to run
vertically through a hole in the floor, and
then terminate horizontally outside—flue
must terminate 300 mm above the ground.
A minimum of 300 mm of straight flue before any bends. This is required due to the heat
produced from the initial section of flue, which could melt the outer plastic. The LSFKIT01 has
the 300 mm min. flue length built in.
With the Linear installed into the support framing:
1. Fit the flue components and lengths of flue pipe as required. Ensure the flue transition
section of the LSFKIT01 is included. NEVER discard this section as this will cause an unsafe
installation due to a buildup of heat in the flue.
2. The flue penetration should be made at the same time as the cutout for the gas connection.
The floor penetration minimum diameter is 80 mm to non-combustible surfaces such as brick,
and 100 mm to combustible surfaces such as plaster.
3. Pass the flue pipe through the internal wall plate and through the floor penetration, and secure
the wall plate in place to seal the floor.
4. Prepare the horizontal section of the flue system under the floor by connecting the flue pipe
and bends as required. Allow for a 2° continuous fall from the first section of the horizontal flue
pipe to the wall penetration.
5. Create the wall terminal, refer p.17, ensuring a 300 mm clearance between the flue terminal
and ground level.
