Typical DM Installation Detail
FOUNDATIONS
Construction begins by providing a suitable foundation
and constructional hearth in accordance with Building
Regulations and site requirements.
OPEN FIRE OPTION
Bed the base plate of the firechest onto a suitable
foundation/constructional hearth in accordance with
Building Regulations and at the level required on site using
Isokern lip glue.
Install the firechest using lip glue making sure all elements
are level. 100mm of brick/blockwork must be built around
the sides and back of the firechest to comply with Building
Regulations. The inside of the firechest must be finished
with a suitable fireback or firebrick slips.
Install the gather using lip glue making sure all the elements
are level. The front face of the gather can be finished with
plasterboard, rendered or clad in masonry. Lintels may
be required above the gather to help carry the brick or
blockwork. The maximum loading capacity of the ISOKERN
firechest and gather is 2500kg.
TIMBER FRAME SOLUTION
For timber framed solution refer to pages 24 - 25
STOVE IN RECESS OPTION
Pre-stressed lintels or a suitable cast-in-situ concrete slab
must be provided above the stove recess, please make sure
they are strong enough to carry the load (see appropriate
Isokern DM drawing for aperture size). It is recommended
to have a minimum of 600mm of stove flue pipe before
connecting to the support block.
The support block is bedded onto the lintels using a weak
mix mortar. A stainless steel adaptor is used to create a
positive connection from the support block to the stove
flue pipe (fibre rope should be used to create a seal).
FREE STANDING STOVE OPTION
A soot door casing and access flue block must be used
below the flue pipe entry. The DM 45˚ access kit is then
used for the connecting flue pipe. A suitable wall sleeve
must be used to seal the cavity wall. Any combustible
insulation within the wall must then be kept away from
the single wall connecting flue pipe by at least 1.5 x its
diameter. Fibre rope is used to seal between the flue pipe
and wall sleeve, a suitable trim collar can be used to finish
the inner wall surface.
