KENT Logfire II - Insert Flue Installation

No part of a building, or any adjacent object, may be above the ue in a circular area of 3
metres from the ue exit.
These heights are given as a minimum, and in actual practice the presence of surrounding
structures, trees, fences, etc. may necessitate additional ue height for satisfactory
performance.

Determine whether the ue pipe will t vertically in the chimney from the heater to the cowl. An
adjustable bend may be required to offset the ue from the heater in order to clear part of the
chimney structure. If an offset is required, it should be tted to the ue outlet on the heater, so
that the ue pipe itself is vertical. The ue pipe should not touch the masonry.
Check chimney for accepting ue is in sound condition, and xing of outer casing or chimney
cap ashing to chimney crest is achievable.

additional 200mm sections of ue as necessary to ensure minimum 1m ue height above roof is
achieved (Refer Fig.2 for more detail). Ensure the 150mm ue pipe extends at least 180mm above
the 200mm ue casing at the top. Trim ues if required.
Join together as many 250mm outer ue casings as manageable with swaged ends up, x
lengths together with 3 rivets or self-tapping screws and slide over 200mm ue casing pipe from
the top down to sit in position onto the 250mm section of ue transition atop the Zero clearance
box. Add additional 250mm sections of ue as necessary to nish at the same height as the
200mm ue liner. Trim last section if necessary.
Fit a suitable ashing over the ue and roof penetration hole to ash the outer casing to the
roof, seal and x ashing to roof and outer liner casing with an appropriate waterproof seal.
Place top spreader bracket in place and tighten, slide the cowl transition over the 150mm ue
pipe until it rests on the top spreader, t the Rain-Hat cowl. Note; Rain-Hat must be removable for
cleaning. In high wind zones secure in place with a self tapper screw.
Where a ue terminates more than one full ue section above the roof penetration, it must be
restrained with guy wires or support bracing bars for stability in high wind conditions.
The ue system should be vertical and without bends. If an offset is required, it should be as close
to the wood re as practicable and should not be offset more than 500mm from the centre line
of the ue stub. Clearances from the ue pipe to combustible materials must be maintained.
Restrictions or leaks in the ue system may reduce the draught, and, in severe conditions, could
cause smoke to enter the room.
NOTE: The ue pipe shall extend not less than 4.6m above the top of the oor protector.
The ue cowl must be at least 0.6m above the highest point of the roof, if within 3 metres of the
ridge. The ue cowl must be at least 1m above the roof penetration if more than 3 metres from
the ridge (Refer Fig. 2).
