Your Hothouse Stove comes packed in a cardboard box. Carefully remove any straps and remove all
cardboard and any plastic packaging, open the door and remove all the contents. See List of
Components section and check contents carefully.

 Remove the coal catcher by lifting it up and rotating it until it can be removed through the open door

of the stove

 Remove the baffle plate from the stove. Please take note of fig. 2 for orientation of baffle when

refitting.

 The flue collar can now be fitted to the top or back of the stove as desired using the M6 fixings and

washers provided. Thread each nut onto the screw first, then put on the washer and place the screw

through the fixing hole on the stove and finally screw onto the collar.

 Fit the blanking plate to the opening that is not to be used in same way as described above for collar.

3 Installation Instructions

WARNINGS AND IMPORTANT SAFETY INFORMATION

READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLATION!

These instructions cover the basic principles to ensure satisfactory installation of the stove, although detail may need slight
modification to suit particular local site conditions. In all cases the installation must comply with current local regulations
including Building Regulations, Local Authority Byelaws and other specifications or regulations including Ireland, UK or
EU standards referred to as they affect the installation of the stove. Approved Document J is particularly important for
England and Wales and can be downloaded for no cost at:

http://www.planningportal.gov.uk/england/professionals/en/4000000000503.html Also of importance are Approved

documents L1 A and B conservation of fuel and power. The Domestic Heating Compliance Guide will also be found useful.

Important Chimney Warning
This stove must not be installed into a chimney that serves any other heating appliance.

Extractor Fan Warning

There must not be an extractor fan fitted in the same room as the stove as this can cause the stove to emit
fumes into the room.

Cleaning and Chimney Sweeping
The appliance, flue & chimney must be cleaned and checked internally and externally regularly in use
and especially after a period on disuse (e.g. after summer). Lift down the baffle at least weekly to check

for build up of soot or debris on the top from the flue pipe. Remove the baffle and check the flue spigot and
connector is fully clear at regular intervals. The chimney and flue connector must be swept at least annually,
more often when used with sooty fuels or damp wood. Any loose, broken or leaking joints or flue ways
MUST be repaired immediately.

Fuels

Only use recommended fuels. The appliance can be damaged by burning petroleum coke, liquid fuels or
general rubbish and this will invalidate your warranty and risk your personal safety. The appliance must

not be used as a rubbish incinerator.

Maintenance

Annual checking and servicing of the appliance and flue by a competent engineer is recommended.

Ventilation

Adequate ventilation is ESSENTIAL for the safe and efficient operation of any solid fuel or wood burning
appliance. Ventilation MUST be provided where required by the stove output or flue under-performance.
Keep all ventilation clear and free of blockage.

Health And Safety Precautions

Handling

Adequate facilities must be available for unloading and site handling. Hothouse Cassette Stoves are very
heavily built so always ask for assistance when lifting and siting the stoves.

Fire Cement

Some types of fire cement are caustic and should not be allowed to come into contact with the skin. In case
of skin contact, wash immediately with plenty of water.

Asbestos

This stove contains no asbestos. If there is a possibility of disturbing any asbestos in the course of
installation then please seek specialist guidance and use appropriate protective equipment.

Metal Parts

When installing or servicing this stove, proper care should be taken to avoid the possibility of personal
injury.

4.0 Installation Information

Thermostat

We recommend that a thermostat control is fitted to your boiler which is used to automatically regulate the
water output temperature and prevent water overheating in the boiler. The thermostat must be fitted as per
the manufacturer‟s instructions which are included with the thermostat.

Chimney

The chimney height and the position of the chimney terminal should conform to Building Regulations.
Minimum chimney height is 4.5m. Check that the chimney is in good condition, dry, free from cracks and
obstructions. The diameter of the flue should not be less than 150mm and not more than 200mm. If any of
these requirements are not met, the chimney should be lined by a suitable method. The chimney must be
swept before connection to the stove.

Where the chimney is believed to have previously served an open fire installation, it is possible that the
higher flue gas temperature from the stove may loosen deposits that were previously firmly adhered, with
the consequent risk of flue blockage. It is therefore recommended that the chimney be swept a second time
within a month of regular use after installation.
If you have any doubts about the suitability of your chimney, consult your local dealer/stockist or chimney
specialist. If there is no existing chimney then either a solid fuel compatible prefabricated block chimney or
a twin-walled insulated stainless steel flue to BS 4543 can be used. These chimneys must be fitted in
accordance with the manufacturer‟s instructions and Building Regulations.

Ventilation

No purpose provided ventilation is required for stoves rated under 5KW. For each KW above 5KW, 550 sq
mm of fixed ventilation is required – i.e. a stove rated at 8KW would require 3 x 550 sq mm = 1650 sq mm
of fixed ventilation. If more than one appliance is installed in the same room, the ventilation requirements
for each appliance must be added together.

Flue Draught

A flue draught of minimum 1.2mm to a maximum 2.5mm water gauge (12 to 25 Pascals) is required for
satisfactory appliance performance. The flue draught should be checked under fire at high output and, if it
exceeds the recommended maximum, a draught stabiliser must be fitted so that the rate of burning can be
controlled to prevent over-firing.

Connection to the Chimney

This appliance is not suitable for use in a shared flue. This appliance requires a direct flue connection to the
spigot. If practical, an existing fireplace opening can be bricked up or sealed with a register plate and a short
length of flue pipe of a minimum 150mm internal diameter may then be used to connect the stove to the
register plate in the chimney. This flue pipe should conform to Building Regulations. The stove must be
insulated and properly fitted into the fireplace opening by back filling with 6:1 ratio vermiculite & cement
mixture using minimal water through the top of the fireplace or flue spigot opening. The surface should be
finished using 1:1:8 mix of cement, lime and sand. The connecting pipe is fitted with the spigot pushed up
from inside the stove and rotated onto its keyhole slots to join to the pipe. Ensure that the pipe end is no
closer than 76mm to the side or rear chimney walls.
