Connection to chimney
All the boilers have a flue gas connector that allows connection to either a masonry chimney or
a prefabricated factory made insulated metal chimney in accordance with the instructions. This
connection should never be reduced in diameter to lower than that of the flue gas connector of
the boiler. In some cases it may be necessary to fit an adapter in the connection pipe to
increase the diameter to the required minimum diameter of 150 mm for burning wood fuel in
accordance with UK regulations. Any connections should be made gas-tight and sealed with a
suitable sealing agent such as fire cement.
Connection to the central heating system
The boilers may be installed on either open vented or sealed fully pumped systems and a
double-feed indirect cylinder to BS 1566 is necessary where there is a combined hot water and
central heating system. Please ensure that a gravity heat-leak radiator/towel rail or equivalent is
used to dissipate heat in the system when the pump is off if required.
The central heating system must be in accordance with BS EN 14336:2004: Heating Systems in
Buildings. Installation and commissioning of water based heating systems. BS EN 12828: 2003;
Heating Systems in Buildings. Design of water based heating systems. BS EN 12831: 2003;
Heating Systems in Buildings. Method for calculation of the design heat load and BS 6880:1988
Parts 1 to 3, Code of Practice for low temperature hot water heating systems of output greater
than 45kW where appropriate.
Electrical connections
The installation of any electrical services during the installation of this boiler and the associated
heating system must be carried out by a registered competent electrician and in accordance
with the requirements of the latest issue of BS 7671.
Commissioning and handover
Ensure all parts are fitted in accordance with the instructions.
On completion of the installation allow a suitable period of time for any fire cement and mortar to
dry out, before lighting the boiler. Once the boiler is under fire check all seals for soundness and
that the boiler and water system are operating correctly. Ensure that the flue is functioning
correctly and that all products of combustion are vented safely to atmosphere via the chimney
terminal.
On completion of the installation and commissioning ensure that the operating instructions for
the boiler are left with the customer. Ensure to advise the customer on the correct use of the
appliance and warn them to use only the recommended fuel for the boiler.
Advise the user what to do should smoke or fumes be emitted from the boiler. The customer
should be advised about restricting access to the boiler by children, aged and/or infirm people.
Important Note: In the event of the appliance failing to light after the initial ignition light-up
process, please switch off the appliance immediately and contact the manufacturer for guidance.
Please do not attempt to re-light the boiler until the issue has been resolved.
