3 INSTALLATION REQUIREMENTS
The installation must comply with regional Building Regulations. The maximum noise level
generated by the appliance is well within the residential noise limitations and is similar to that of
a high efficiency oil boiler.
3.1 General Requirements
3.1.1 Hearth
The appliance has a hearth temperature of between 50°C and 85°C and should be stood on a
rigid, nonporous, noncombustible base, which is not softened by heat, to comply with the
Building Regulations.
3.1.2 Service Access
Clearance should be provided above and in front of the appliance to allow for routine servicing.
The rear of the appliance casing and any one side panel may be positioned beside a wall or
boundary. At least 600mm is required at the front and accessible side of the appliance, although
maximising access is recommended.
Please refer to local Building Regulations for permissible distances from combustible surfaces.
If the appliance is intended for internal installation please refer to local Building Regulations for
ventilation sizes to ensure sufficient combustion air at maximum output. It may be necessary to
filter combustion air as it enters the room where the appliance is located if there is a possibility
of high levels of dust or particulates.
3.1.3 Heating System
The heating system should be installed to current HVAC codes of practice. Before installing the
appliance the new or existing system must be thoroughly flushed to clear all sludge or other
foreign matter such as solder, steel wool and copper filings.The system must be cleansed,
neutralised and protected from corrosion in accordance with BS EN 12828, BS EN 12831, BS
EN 14336 and BS7593 using suitable cleansing agent(s) and inhibitor(s) and carried out in
