Up And Back Flue Assembly - Rinnai Linear Series Flue Installation Manual

Up and back flue assembly

Up and back through 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.
A 2° fall is required towards the flue
termination. The flue must terminate
300 mm above ground level.
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. Assemble the flue components as pictured above. 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. Create the wall penetration. The minimum diameter required is 80 mm to non-combustible
surfaces such as brick, and 100 mm to combustible surfaces such as plaster. Allow for a 2° fall
to the wall terminal.
3. Pass the flue pipe through the internal wall penetration.
4. Make the Linear exhaust and combustion air
hose connections, refer p.9.
5. Create the wall terminal, refer p.17.
