In general
• The installation instructions must be followed in order to comply with the guarantee of the
system and we recommend that it is installed by a HETAS Approved Installer.
• The installer must inspect and test the finished system and leave the completed notice plate
and results from the test with the householder.
• The accompanying documentation should be kept for the entire life of the installation.
• Make sure that the contents of the shipment are consistent with the delivery note and that
they are not damaged. Transport damage must be reported to the driver at delivery and
noted on the consignment notes.
CHIMNEY TYPE AND DISTANCE TO COMBUSTIBLES:
• Minimum distances to combustible material from the chimney is given in the CE designation
(see page 3).
• For stoves, fireplace inserts and boilers, distances to combustible material are also given in the
CE designation (see page 4).
DEFRA EXEMPT
• Celsius is approved for installation in Smoke Control Areas in the United Kingdom, when
operated in accordance with the instruction and installation manuals and when any conditions
are met.
• Level 5 of the clearSkies mark is the
highest possible energy efficiency
rating available. Celsius has achieved
the highest level in clearSkies
certification, which means that it
exceeds the minimum performance level for Ecodesign Regulations.

Distance requirements:
When choosing a location, consider the illustrations below and the distances to combustible
materials.
When installing against non-combustible material, the requirements of the building regulations
must be followed.
As can be seen from the above drawings and the instructions for the structure of the frame, it is
required that air circulation has been established around the insert itself, corresponding to 230
cm³ of air above the insert appliance immediately below the top plate as well as air intake just
below the base plate. This air circulation is intended to ventilate and heat the room.
A hearth must be installed in line with Building Regulation guidance.
Note: CE mark and technical specications are given on page 4

Location of the system
Make sure that the location of the installation is accurately measured and that any installation
takes into account obstacles such as floors and ceilings and the roof construction.
FOUNDATION AND REINFORCEMENT
Before building the frame and chimney, make sure that the floor can carry the weight of the
whole system and that the floor is stable, level and non-flammable.
The foundation should be at least a 100mm thick reinforced concrete slab.
LIP GLUE FOR THE PUMICE COMPONENTS
Schiedel ISOKERN Chimney Adhesive is used for the construction of all the Pumice elements
within the frame and chimney. The mixing instructions are shown on the packaging.
Apply the glue using the mortar bags provided to achieve a uniform application rate. Apply
sufficient glue so that the glue is pressed out between the blocks during assembly.
Excess glue should be removed continuously inside and outside using a trowel and subsequently
cleaned with a damp, soft brush or sponge.
RENDER
Schiedel ISOKERN chimney render is used for surface treatment. The mixing instructions are
shown on the packaging.
The external part of the chimney that is open to the elements must be rendered to avoid
moisture entering the chimney modules.

6
Assembly
Measure and note the desired
location of ISOKERN CELSIUS
solution. Apply Schiedel ISOKERN
chimney glue to the pre-prepared
load bearing reinforced concrete
slab and place first pumice block.
Use a spirit level to ensure that the
block is positioned correctly, then
the whole installation remains in
level throughout its length.
Apply glue to the whole surface of
the block before placing the stove
recess baseplate.
Always wipe off excess glue and
check the level regularly with a
spirit level.
Apply glue to the whole top
surface of the module before
placing the the next block.
Wipe away any excess glue.
Apply glue all around the edge,
with the exception of the front
edge where the appliance will be
fitted.
Place first stove recess block.
Apply glue to the module outer
edge, with the exception of the gap
for the first ventilation grill.
The grill should be fitted once the
blocks have been rendered.
Repeat this process again for each
of the 7 U shaped stove recess
blocks.
There are 7 layers to fit in the
opening for the insert.

Glue the 3 metal plates onto the
base plate within the opening for
the insert so they lie under the
3 adjustable feet (bolts) in the
bottom of the appliance.
Assembly
Apply glue around the edge and
place the first top section above
the opening.
Apply glue to each block edge,
with the exception of the gap for
the 2nd ventilation grill
The grill should be fitted once the
blocks have been rendered.
89
Apply glue before fixing the top
plate in position.

Fasten fibre tape once around the
underside of the flange of the air
outlet.
Push the long end of the air outlet
up through the slit in the top plate
on the frame, and put 2 layers of
fibre tape around the protruding
air outlet before sliding them down
to seal the gap around the outlet.

The door is removed first (the
door can be lifted off at approx. 10
cm open position).
Step 1 Remove vermiculite baffle
plate
Step 2 Remove log retainer, base
panels and grill.
Step 3 Remove the back plate and
side plates.
Remove the 2 thin cover plates,
to get access to the adjustable
feet (bolts) at the bottom.
(IMPORTANT! Install the
plates in position before the
bottom vermiculite panels are
reassembled).
Now slide the appliance into
position and adjust and fix using
the 3 screws at the bottom.
Putting your hand in through the
top hole for the ventilation grill,
pull the air inlet and flue pipe down
into position. Glue is not required.
The steel pipe is sealed into the
stove using fire cement.

plates.
Step 2 Fit log retainer, base panels
and grill.
Step 3 Fit vermiculite baffle plate.
Step 4 Fit the door.
The octagonal pumice starter
flue block fits inside the octagonal
stainless steel adaptor.
Make sure the socket is uppermost.
The Octagonal stainless steel
adaptor slides down inside
the stainless steel pipe shown
previously. The bottom of the
Octagonal adaptor lies flush onto
the Pumice top plate.
The first outer chimney block is
glued into place, making sure it’s
square and level.
Continue adding inner flue blocks
and outer casing using lip glue on
each joint on both inner and outer
blocks.

To finish off add render with
reinforcement mesh being used up
to ground floor ceiling.
Apply a thin layer of render and
press mesh into the render.

Code 4 lead flashing to be fitted at roof level as per Building Regulations. We
recommend that you scorch a 5-10mm deep channel into the outer surface of the
casings and fold in the top edge of the flashing.
Finish the outer surface of the casings above the roof with 2 part waterproof render.
The recommended mix is 1:2:5-6 cement:lime:sand for the undercoats. 1:2:8-9
cement:lime:sand for the final coat. The number of coats required will depend upon
the degree of exposure, generally a two coat mix is acceptable. The mix may vary due
to climate conditions, the thickness of any one coat should not exceed 15mm, and each
subsequent coat should be reduced by approximately 3mm. Isokern concrete capping
for render to be lip glued onto the last casing.

the inner flue block.
Make sure it’s a tight fit and that
approx. 10mm gap remains from
the underside edge of the top ring
to the capping.
29
High tensile steel reinforcement rods will be required for all chimneys with a height
that exceeds 1.4m above the roof line, 1.1m if the wind speed exceeds 44ms.
These rods are available from Isokern and must be grouted (1:3 cement/sand) into the
holes provided in the outer casings. You must start the rods at least the same height
below the roof as what’s above, please check with our technical department.
