3.0 INSTALLATION
THE INSTALLATION OF THIS FIREPLACE,
CONSTRUCTION OF THE FIREPLACE ENCLOSURE AND
THE FINISHING AND COMMISSIONING OF THE
INSTALLATION IS A HIGHLY SPECIALIST TASK. ONLY
ESCEA TRAINED AND APPROVED INSTALLERS SHOULD
BE USED. FAILURE TO FOLLOW THESE REQUIREMENTS
WILL VOID ALL WARRANTY TERMS.
3.1 INSTALLATION - GENERAL
THIS APPLIANCE AND ITS COMPONENTS ARE
DESIGNED TO BE INSTALLED AND OPERATED AS A
SYSTEM. ANY ALTERATION TO OR SUBSTITUTION
FOR ITEMS IN THIS SYSTEM, UNLESS ALLOWED BY
THESE INSTALLATION INSTRUCTIONS, WILL VOID THE
LISTING AND MAY VOID THE PRODUCT WARRANTY.
IT MAY ALSO CREATE A HAZARDOUS INSTALLATION.
READ THROUGH THESE INSTRUCTIONS THROUGHLY
BEFORE STARTING YOUR INSTALLATION AND FOLLOW
THEM CAREFULLY THROUGHOUT YOUR PROJECT.
BEFORE BEGINNING YOUR INSTALLATION, CONSULT
YOUR LOCAL BUILDING CODE TO ENSURE
COMPLIANCE.
• Non-toxic smoke will be emitted during the paint curing
process, to help dissipate the smoke open a window near the
appliance.
• Remove any dust or debris off the top of the appliance
before firing the appliance as the paint will become soft as the
appliance heats up and will harden as the appliance cures. To
cure the paint on your appliance burn your appliance
moderately hot during the first few fires.
• To keep the door gasket from sticking to the appliance as
the paint is curing; periodically open the fireplace’s door.
• For the first two weeks use generous amounts of fuel and
burn the appliance with the air control (if applicable) fully open
for an hour as the appliance goes through a process of
eliminating moisture in the steel and firebricks. The initial heat
output will be reduced while the moisture is being drawn from
the appliance and it will be necessary to build several hot fires
to remove this moisture.
DURING THIS PROCESS DO NOT OVERFIRE THE
APPLIANCE.
REDUCE THE AMOUNT OF AIR COMING INTO THE
APPLIANCE IF THE APPLIANCE OR CHIMNEY BECOMES
RED.
The chimney vent system used on your wood burning
appliance should be designed with the least amount of
restriction possible to enable the exhaust products to easily
flow through it. Chimney vent systems that are too short or too
long can also have an adverse effect on the flow of exhaust
through it. Offsets in the flue can restrict the flow of exhaust
gases and may require an increase in the overall flue length.

12
630359_5
The wood burning appliance and chimney vent system also
requires a sufficient supply of combustion air not only to
support the combustion in the combustion chamber but to
replace the exhaust leaving it so it can flow freely up through
the vent system and out into the atmosphere. It is the correct
balance of combustion air and the chimney vent system that
will ensure the appliance provides you with its optimum
performance.
Be sure to provide sufficient combustion air when taking
combustion air internally. There are many other appliances in
your home competing for air such as: a kitchen range hood,
forced air heating devices or a bathroom exhaust fan.
ENSURE THAT THE LIFT DOOR TRANSIT SCREW(S) ARE
REMOVED PRIOR TO CONSTRUCTING THE SKAMOTEC
ENCLOSURE AND ‘BOXING IN’ THE APPLIANCE.
WEAR GLOVES AND SAFETY GLASSES FOR
PROTECTION.
WEAR A SUITABLE RESPIRATOR MASK WHEN CUTTING
THE SKAMO ENCLOSURE BOARD.
CAREFULLY FOLLOW THE INSTRUCTIONS FOR
ASSEMBLY. FAILURE TO DO SO MAY RESULT IN A FIRE,
ESPECIALLY IF COMBUSTIBLES ARE TOO CLOSE TO
THE APPLIANCE OR CHIMNEY AND AIR SPACES ARE
BLOCKED, PREVENTING THE FREE MOVEMENT OF
COOLING AIR.
DO NOT DRAW OUTSIDE AIR FROM GARAGE SPACES -
EXHAUST PRODUCTS OF GASOLINE ENGINES ARE
HAZARDOUS. DO NOT INSTALL OUTSIDE AIR DUCTS
SUCH THAT THE AIR MAY BE DRAWN FROM ATTIC
SPACES, BASEMENTS OR ABOVE THE ROOFING WHERE
OTHER HEATING APPLIANCES OR FANS AND CHIMNEYS
EXHAUST OR UTILIZE AIR. THESE PRECAUTIONS WILL
REDUCE THE POSSIBILITY OF APPLIANCE SMOKING OR
AIR FLOW REVERSAL. THE OUTSIDE AIR INLET MUST
REMAIN CLEAR OF LEAVES, DEBRIS, ICE AND/OR SNOW
OR ANY OTHER OBSTACLES. IT MUST BE
UNRESTRICTED WHILE APPLIANCE IS IN USE TO
PREVENT ROOM AIR STARVATION WHICH CAN CAUSE
SMOKE SPILLAGE AND AN INABILITY TO MAINTAIN A
FIRE. SMOKE SPILLAGE CAN ALSO SET OFF SMOKE
ALARMS.
NEGATIVE PRESSURE WITHIN YOUR HOME MAY
INADVERTENTLY AFFECT YOUR APPLIANCE.
DO NOT USE MAKESHIFT COMPROMISES DURING
INSTALLATION. DO NOT BLOCK OR RESTRICT AIR,
GRILLE OR LOUVRE OPENINGS.
ALWAYS MAINTAIN THE MINIMUM AIR SPACE REQUIRED
TO THE ENCLOSURE TO PREVENT FIRES.
DO NOT PACK REQUIRED AIR SPACES WITH
INSULATION OR OTHER MATERIALS.

3.2 INSTALLATION - OVERVIEW
CONVECTION
Spartherm wood fires are convection fires with “central
heating” capabilities. Convection means that there is a natural
circulation of air, which ensures that the heat is distributed
more evenly throughout the entire room or dwelling. The cold
air is drawn in at the base of the fire, and then moved up
through the convection channel, which runs along the fire’s
combustion chamber. The heated air pours out at the top of
the fire via the duct spigots (4 off).
The hot air can then be completely or partially distributed to
other areas of the same room or alternative rooms via flexible
aluminium ducting or vents within the cavity walls.
The total convection air venting open surface area must be at
least 880 cm2 distributed between the aluminium ducted vents
and cavity vents. In addition, two ‘intake’ vents of at least 90 x
300 mm or an open surface area of at least 540 cm2 must be
provided into the cavity surrounding the fireplace to provide
adequate air for convection. This is in addition to the
requirements for combustion air as outlined in the planning
section.
The intake vent(s) should be placed as low as possible in the
cavity ideally below 300 mm from the floor. They should be no
more than 300mm from the bottom of the appliance. Two
vents (one each side) is preferential over one.

630359_5
INSTALLATION PROCESS - DETAIL
THE AIR TEMPERATURES WITHIN THE SKAMO
ENCLOSURE BOARD ENCLOSURE CAN BE VERY HIGH.
THE ENCLOSURE MUST BE DESIGNED AND
CONSTRUCTED IN A MANNER TO COMPLETELY
NEGATE THE RISK OF ADJACENT HEAT SENSITIVE OR
COMBUSTIBLE MATERIALS BECOMING TOO HOT.
The cavity / housing for the fireplace must be constructed
entirely from skamo enclosure 40mm calcium silicate board
only.
Refer to the skamo enclosure board guidelines as an aid to
using this material: www.sparthermfires.co.nz/skamotec
(Information is an aid only – all installation requirements must
comply with this document).
Combustible or heat sensitive materials shall NOT be used
within the construction of the cavity / housing.
Do not line the outer face of the skamo enclosure board with
combustible materials (plasterboard, etc.).
Skamo enclosure board can be easily worked or formed using
conventional hand/ power tools using dust extraction where
necessary.
In unsupported sheet form, the skamo enclosure board is
fragile and should be handled with care.
In areas that are likely to become hot (above the fireplace
door etc.) then an approved adhesive with a higher operating
temperature is required. For these areas you must use skamo
enclosure glue. Recommended screws are 10g x 75mm on
200mm to 300mm centres. Where a skamo enclosure board
will have glue applied (i.e. joints, back blocking, double
layers, flashing areas, etc.) sheets must be primed with
either Mapei Primer G or Skamol Enclosure Primer prior
to gluing.
Metal flashings have been supplied to help ensure air
tightness of the joints at the top of the cavity. These can be
secured to the skamo enclosure board using 2.0 x 30mm
diamond point plain shank nails.
The fire or door frame must not come into contact with the
skamo enclosure board. A gap of at least 5mm between the
fire and the skamo enclosure board is advised (also refer to
minimum clearance table). The fire will expand and contract
during use. If in contact with the wall substrate this will cause
cracks in the wall.
Consider and plan for the incorporation of the flue damper
control lever and shaft shown below. All models require the
mandatory use of these parts (see specification table).
Figure 9

16
630359_5
A suitably sized hole will need to be drilled in the steel
convection air jacket to accommodate the flexible shaft to suit
the planned position of the control lever.
The fireplace must be installed on a non-combustible base
that is suitably engineered to support the weight of the
appliance. We recommend a reinforced concrete slab (min.
100mm thick).Suitable seismic restraint must be provided.
This can easily be achieved by screwing or bolting the 4 feet
of the fireplace securely to the concrete slab.
Combustion air – In addition to providing cavity (convection)
intake air vents it is a requirement to also provide air for
combustion. If taking the combustion air from outside of the
building (Direct vent) through a Ø150mm (165mm OD) pipe
and into the appliance via the optional appliance adaptor
(recommended), ensure that the run of the Ø150mm pipe is
as short as possible and as unrestricted as possible.
Try to use 45° bends in lieu of 90° bends and restrict the total
number of bends to 2. If the pipe is in an area where
condensate may form on the outside then adequate provision
for lagging/insulation of the pipe outer should be planned.
Varia Bh-P7 inlet Varia ASh-P8, A-FDh-P8,
A-FDh-P8 & 2L/R 80h-P7 inlet
It is also advised to make provision for periodic cleaning of the
pipe inner by providing a “rodding eye” or other means of
access. Where the pipe terminates on the outside of the
building it should be suitably protected from water, foreign
matter ingress and rodent/bird/flying insect ingress.
The Ø150mm pipe run within the skamo enclosure board
enclosure should be made from a heat resistant material
(galvanised steel, stainless steel etc.). You may transition to
PVC pipe or similar 300mm after the pipe has exited the
Skamotec enclosure.
Providing a means to access each of the pipe joints for future
inspection and cleaning is recommended.
Considerations for positioning the combustion air intake
vent & pipe
•Ensure that the chimney top and the air intake are
in the same pressure zone. Different zones could
cause problems particularly on windy days.
Figure 10

17
630359_5
•Ensure that the air intake pipe cannot suck air out of
the system (placed in negative pressure zone)
•Ensure that smoke from the flue will not be sucked
in again by the air intake.
If taking combustion air from the immediate room, ensure that
the area has sufficient ventilation. Ensure to comply with
AS/NZS 2918:2001 clause 7.1 in addition to the requirements
for convection air intake as set out in 3.2 installation overview.
If taking combustion air from the immediate room it is required
that “intake” venting of the cavity of at least 717 cm2(or
540cm2if a 150mm outside combustion air kit is connected).
This vent should be connected into the cavity at a level below
300 mm from the floor.
Intake vents must be constructed entirely of non-combustible
materials and must not be able to be closed or easily
obstructed.
3.4 DUCTING INSTALLATION (CONVECTION
AIR)
Plan your use of the insert optimally. By installing hot air vents
and flexible aluminium hoses (available as a kit) on top of the
fire, it is possible to “distribute” the heat to other rooms/areas
if required.
Consider the placement of convection vents/outlet holes.
Note: the heat will tend to seek the one at the highest level
and/or least resistance to flow. Balancing the system in terms
of flow resistance should help optimise heat distribution.
Figure 11
Figure 12

18
630359_5
Ensure that the area requirements are respected and that the
vents are not able to be inadvertently or otherwise blocked,
closed or obstructed.
We do not recommend the use of floor vents.
The total aluminium ducting length for each of the 4 outlets
should not exceed 7.0M.
The minimum vertical rise before transition to a horizontal
direction should be 0.5M.
Use this chart to estimate the approximate initial vertical rise
of the top of the appliance required for the length of horizontal
ducting to be used.
Any horizontal elements should have a “rise” of at least 3°
towards the outlet to encourage and maintain ‘thermal
syphoning’.
Ensure that the ducting is well supported throughout its length
and that no downwards direction or “dips” in the ducting are
present as this will prevent or impede air flow.
THE VENT DISCHARGE AIR MAY BE VERY HOT AND
COULD PRESENT A FIRE OR HEAT DAMAGE RISK.
ENSURE TO COMPLY WITH THE MINIMUM DISTANCE TO
COMBUSTIBLES PUBLISHED IN THIS DOCUMENT
PARTICULARLY WHEN PLACING HEAT SENSITIVE
MATERIALS SUCH AS ORNAMENTS, ARTWORK AND
SOFT FURNISHINGS.
Figure 13
Figure 14

19
630359_5
TWO DIFFERENT TYPES OF CONVECTION AIR VENTS
MUST BE PROVIDED;ducted vents (vents connected to the
appliance spigot with flexible aluminium ducting) and non-
ducted vents (an aperture cut into the skamotec cavity wall
and finished with a decorative grill if desired. It is mandatory to
have at least 1 non ducted vent in the cavity wall (not
connected directly to the appliance). The minimum size for the
non-ducted vent is 176cm2.
If the number of ducted vents is decreased then the non-
ducted vent open surface area must be increased accordingly:
Number of ducted vents (attached to
appliance)
Open surface area of non-ducted vent
in cavity
4 x 176cm2
176cm2
3 x 176cm2
176cm2 X 2 =352cm2
2 x 176cm2
176cm2 X 3 =528cm2
1 x 176cm2
176cm2 X 4 =704cm2
0
176cm2 X 5 =880cm2
THE AIR EXPELLED FROM THE DUCTING / VENTS IS
HOT AND MAY PRESENT A RISK OF BURNS OR HEAT
DAMAGE.
When placing outlets in rooms other than the room the
appliance is installed, it is important to allow for return air to
equalise pressure between the rooms.
There may be discoloration of the wall above the fire doors
and the convection outlet vents/holes. Only suitably rated and
approved aluminium flexible ducting and discharge vents must
be used – these have been carefully chosen to work safely
with your appliance. These are available solely from your
dealer/distributor.
Wherever the ducting penetrates the skamotec cavity, a wall
thimble that constrains the ducting, entirely seals the
penetration from the cavity and controls the distance to
combustibles or heat sensitive materials shall be used. Please
refer to your dealer for suitable parts.
Aluminium ducting and wall sealing plate
Figure 15
Figure 16

20
630359_5
Outside the confines of the cavity, the aluminium ducting
should be run and completely housed within a box cavity
construction made entirely from skamo enclosure board. Do
not use any combustible materials within this boxing.
Wherever the discharge air vent is located in a wall other than
the fireplace cavity (constructed from skamo enclosure
board), the wall facing material immediately surrounding the
discharge air vent must be constructed of a heat resistive
insulating material such as Promina or Eterpan board (min
10mm thick). Any wall support elements/structure made of
combustible materials immediately adjacent the vent should
be protected from heat by the use of skamo enclosure board
sheets as shown:
The discharge vent must be no closer than 400mm to a
heat sensitive ceiling or overhead projection.
Escea accepts no liability for improper installation or
consequential damages.
PROVISION MUST ALWAYS BE MADE FOR RETURN AIR
FROM HEATED ROOMS E.G. UNDERCUT DOORS, VENTS
OR NATURAL LEAKAGE.
WARNING: OVERHEATED ROOMS OR AREAS ARE NOT
SAFE FOR INFANTS!
