Up and back ue assembly
Air inlet pipe
Flue exhaust
outlet
45 ° bends
LSFKIT01
Up and back through wall ueing 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 ue pipe.
A 2° fall is required towards the ue
termination. The ue must terminate
300 mm above ground level.
With the Linear installed into the support framing:
1. Assemble the ue components as pictured above. Ensure the ue 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 ue.
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 ue 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.

LSFKIT01, ue transition
MUST BE connected
A minimum of 300 mm of straight ue before any bends. This is required due to the heat
produced from the initial section of ue, which could melt the outer plastic. The LSFKIT01 has
the 300 mm min. ue length built in.
