FREESTANDING WOOD FIRE INSTALLATION
To adequately install a Kent freestanding wood fire the following items are required: an
assembled wood fire, a floor protector, a flue system and a suitable flashing system for flashing
the roof penetration.
An insulating floor protector is not required for the Kent freestanding wood fire, but a single layer
ash floor protector of non-combustible material must be used. The floor protector must extend
under the appliance and not less than 300mm in front of the fuel-loading and ash removal
openings. The width of the floor protector shall not be less than the width of the appliance and
shall extend not less than 200mm from each side of any ash removal or fuel-loading openings.
Select a location for the wood fire, considering the minimum clearances required (Refer Fig.1, table 2, ).
Place the wood fire into the desired position and plumb for the ceiling and roof penetrations.
Allow for 150mm diameter flue pipe, 200mm diameter inner casing and 250mm outer casing.
Check the proposed route of the flue to ensure it is clear of roof trusses and rafters in the ceiling
space or other obstructions. It may be necessary to move the location of the wood fire to
ensure this.
Once the location is confirmed, the wood fire must be restrained against movement due to
earthquakes. The Kent freestanding wood fire is restrained by fixing the wood fire to the floor
with two bolts of 6mm minimum diameter through the holes provided in the plinth base, through
the floor protector and floor. For solid concrete floors, use 8mm DYNABOLTS
®
or similar, with a
minimum depth of engagement into the floor of 50mm.
STANDARD FLUE INSTALLATION
Cut a 260mm square hole for the passage of the flue and casings through the ceiling. Trim
timber as necessary and reframe to fix 250mm outer flue casing at ceiling height.
Extend plumb line up to roof and cut a hole for the passage of the 250mm flue casing to pass
out through the roof.
Position starter section of 250mm Ø galv flue casing with swaged end up and bottom flush
with the underside of the ceiling. Fix in position with adequate screws fitted from inside the flue
through to the framing of the 260mm square opening in the ceiling at the 4 intersecting points.
Back off each screw 5mm so each fixing point has a 5mm gap between 250mm Ø flue casing
and 260mm timber framed hole.
Start with the black sections of s/s flue. Join the required number of 150mmØ flue pipes together
by inserting the swaged end of the upper piece into the plain end of the lower piece so the
flue will terminate in the desired position (See Fig.2). Drill and fix each length with 3 stainless
steel rivets or self-tapping screws. It is important that each flue joint is sealed with commercially
available flue sealing compound, including the join between fire and first section of flue pipe.
Before fitting the flue to the fire, place the ceiling plate over fire spigot ensuring it is the right
way up.
The 150mm Ø s/s flue sections can either be lowered from the top fully assembled onto the fire,
or fed up from the bottom a length at a time ensuring all joints are sealed and fixed properly.
Slide the 200mm Ø inner casing/s into place crimped end up, between the outer casing and
the 150mm Ø flue pipes. Slide down so the bottom flue spacer of the 200mm Ø section sits on
the crimped seat of the 250mm Ø starter flue casing. Extend the 200mm Ø flue casing/s up until
it is through the roof and between 200mm and 600mm from the top of the 150mm Ø flue that is
finished in the desired position. Trim flues as required.
Extend up 250 Ø outer casing/s as required noting that the slip section supplied with the standard
flue kit is the last casing to be added this section is adjustable slide in position and secure so the
top of this section is 180mm below the top of the 150 Ø flue.
Fit a suitable flashing over the flue and roof penetration hole to flash the outer casing to the
roof. Seal and fix flashing to roof and outer casing with an appropriate waterproof seal.
Place the top flue spacer bracket in position and tighten. Slide weather cowl over flue pipe until
it sits firmly on spacer bracket. Fit the rain hat cowl. NOTE: it must be removable for cleaning.
