INSTALLATION
OPTIONAL ADD IN BOILERS
Aarrow Ecoburn Wood and Multifuel stoves offer the option of a slab boiler, which occupies the position of the rear firebox liner panels.
Fitting:
•Remove the fuel retainering bars, rear firebox liner panels and throat plate.
•Knock out the blanking discs in the back plate corresponding to the terminals on the boiler.
•Introduce the boiler to the appliance through the main fire door and locate the terminal pipes through the back plate holes and seal around boiler terminals with fire cement.
•Engage locking nuts to the thread of the terminals and tighten to secure the boiler in position, ready for connection to flow and return pipes.

Direct Systems
Stainless steel boilers, either factory fitted or
To connect the cylinder use 28mm copper pipes. Ensure that the pipes rise continuously to the cylinder.
Ensure that the runs are not too long, i.e. 20ft maximum each for flow and return. Install the cylinder above the level of the fire, and as close to it as possible. (the higher the cylinder the faster the circulation). Ensure that no valves are present in the circulating pipes.
Indirect Systems- The Domestic Hot Water Circuit
•Replace throat plate and the fuel retainering bars.
Note: On boilers the terminal which is approximately flush with the edge of the boiler and marked "TOP" must be fitted uppermost, to prevent "Kettling".
WATER CONNECTIONS
Heating systems
The size of the heating system which can be run, will depend on the output rating of the appliance. It will be necessary to work out heat loss calculations for the system proposed in order to establish the kW/hr rating. An appliance that will meet this figure can then be chosen; (for boiler outputs please refer to the brochure).
The constructional requirements of installing and connecting the appliance also need to be taken into account when selecting. Design and calculations for individual heating systems should be carried out by a qualified heating engineer. In many cases your
In addition to providing hot water the primary circuit is essential in providing a "heat leak" to absorb excessive heat produced in the event of the circulation pump shutting down.
Heat is produced in varying quantities while the fire is alight and care must be taken to ensure that effective circulation can occur around the primary circuit to carry heat away and thus stop boiling. The output of any radiator installed as a "heat leak" should not be less than 10% of the rated output of the appliance. The radiator should not be fitted with a control valve.
The cylinder must be of the indirect type with a minimum capacity of 110 litres, conforming to BS 1566 part 1.
