Installation Instructions
READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLATION
These instructions cover the basic principles to ensure satisfactory installation of the stove, although etail
may nee slight mo ification to suit particular local site con itions. In all cases the installation must comply
with National an European Buil ing Regulations, Local Authority Byelaws an other specifications or
regulations as they affect the installation of the stove.
Health an Safety Precautions
Han ling
Adequate facilities must be available fo unloading and site handling.
Fire Cement
Some types of fi e cement a e caustic and should not be allowed to come into contact with the
skin. In case of contact, wash immediately with plenty of wate .
Asbestos
This stove contains no asbestos. If the e is a possibility of distu bing any asbestos in the cou se
of installation then please seek specialist guidance and use app op iate p otective equipment.
Metal Parts
When installing o se vicing this stove, ca e should be taken to avoid the possibility of pe sonal
inju y.
Please note:
Any white deposits on the stove joints a e caused by humidity eacting with the joint sealant.
These deposits may be b ushed off and, if necessa y, blackened with a p op ieta y stove polish.
Important Warning
This stove must not be installed into a chimney that se ves any othe heating appliance.
No pu pose p ovided ventilation is equi ed fo stoves ated unde 5KW. Fo each KW above
5KW, 550 sq mm of fixed ventilation is equi ed – i.e. a stove ated at 8KW would equi e 3 x
550 sq mm = 1650 sq mm of fixed ventilation. If mo e than one appliance is installed in the same
oom, the ventilation equi ements fo each appliance must be added togethe .
The e must not be an ext acto fan fitted in the same oom as the stove as this can cause the stove
to emit fumes into the oom.
Installation
Thermostat
We ecommend that a the mostat cont ol is fitted to you boile which is used to automatically
egulate the wate output tempe atu e and p event wate ove heating in the boile . The the mostat
must be fitted as pe the manufactu e ’s inst uctions which a e included with the the mostat.
Chimney
The chimney height and the position of the chimney te minal should confo m to Building
Regulations. Check that the chimney is in good condition, d y, f ee f om c acks and obst uctions.
The diamete of the flue should not be less than 125mm and not mo e than 200mm. If any of
Revised 11-07-11
these equi ements a e not met, the chimney should be lined by a suitable method. The chimney
must be swept befo e connection to the stove.
Whe e the chimney is believed to have p eviously se ved an open fi e installation, it is possible
that the highe flue gas tempe atu e f om the stove may loosen deposits that we e p eviously
fi mly adhe ed, with the consequent isk of flue blockage. It is the efo e ecommended that the
chimney be swept a second time within a month of egula use afte installation. If you have any
doubts about the suitability of you chimney, consult you local deale /stockist.
If the e is no existing chimney then eithe a p efab icated block chimney o a twin-walled
insulated stainless steel flue to BS 4543 can be used. These chimneys must be fitted in
acco dance with the manufactu e ’s inst uctions and Building Regulations.
Flue Draught
A flue d aught of minimum 1.2mm to a maximum 2.5mm wate gauge is equi ed fo
satisfacto y appliance pe fo mance. The flue d aught should be checked unde fi e at
high output and, if it exceeds the ecommended maximum, a d aught stabilise must be fitted so
that the ate of bu ning can be cont olled and to p event ove fi ing.
Connection to the Chimney
An existing fi eplace opening can be b icked up o sealed with a egiste plate. A sho t length of
flue pipe of a minimum 125mm inte nal diamete may then be used to connect the stove to the
chimney. This flue pipe should confo m to Building Regulations. Ensu e that the pipe end is no
close than 76mm to the side o ea chimney walls.
Ideally, the old fi eplace should be filled in so that the e is a smooth st eamlined ent y into the
flueway. The length of any ho izontal un of flue pipe must not exceed 125mm.
It is essential that all connections between the stove and chimney-flue a e sealed and made
ai tight. This appliance is not suitable fo installation in a sha ed flue system.
Both the chimney and flue pipe must be accessible fo cleaning and if ANY pa ts of the chimney
cannot be eached th ough the stove (with baffle emoved), a soot doo must be fitted in a
suitable position to enable this to be done.
Material Clearances
The stove can be ecessed in a suitable sized fi eplace but a pe manent f ee ai gap of at least
150mm must be left a ound the sides and top and at least 50mm at the back of the stove to obtain
maximum heat output and fo access to the ea of the stove.
All non-combustible walls close than 400mm to the stove should be at least 75mm thick. In all
instances the back wall of the fi eplace ecess and the hea th should be made of non-combustible
mate ial. Allow an ap on of at least 300mm at the f ont of the stove and 150mm on eithe side.
The hea th on which the stove is to be placed should not be less than 125mm thick and should be
in acco dance with the cu ent building egulations.
Ca e should be taken to level the stove using the adjusting sc ews in the feet.
The appliance shall be installed on a floo with adequate load-bea ing capacity. If the existing
const uction does not meet this p e equisite, suitable measu es (e.g. load distu bing plate) should
be taken to achieve it.

Revised 11-07-11
It is strongly recommen e that this stove is fitte to your heating system by a
knowle geable, experience an suitably qualifie (Hetas or equivalent) plumber or
Heating Engineer with experience in fitting boiler stoves. If fitte incorrectly it coul result
in serious amage to your home heating system. Plumbing shoul be carrie out in
accor ance with Relevant Buil ing Regulations an safe practices. The manufacturers
cannot be hel responsible for any losses ue to incorrect specification or connection of the
heating system.
Gravity Circuit
Do Not – Unde any ci cumstances connect the stove to a sealed (p essu ised) heating system
o an unvented HW cylinde
Do Not – Link the stove into a heating o hot wate system with an existing boile without the
use of suitable equipment such as a neut alize . When fitting this type of system the neut alize
manufactu e ’s inst uctions must be followed.
Do – Fit an open cold feed and heade expansion tank with sepa ate cold feed and vent pipes.
The cold feed and vent pipes must be unvalved. The open vent pipe should have a diamete of
22mm and ise continuously f om the boile .
The g avity ci cuit should connect to a domestic indi ect hot wate cylinde of minimum 135lt
capacity, using 28mm flow and etu n pipes, ising continuously f om the boile to the cylinde .
Any nominally ho izontal uns of g avity pipewo k should slope upwa ds at not less than 1:30.
The base of the hot wate cylinde should be located at least 150mm above the top of the stove.
The g avity ci cuit must not contain any shut off valves and should be fully lagged to minimise
heat loss. The pipes should not exceed 7.8 mete s (25ft) in length to/f om the cylinde . In
gene al, the sho te the un of pipewo k the less heat loss and the mo e efficient the wate
heating.
