Wet Stove Installation Guide
6.2
Integral Boilers
Integral boilers should only be connected with the flow and return
connections of any circuit on opposite sides of the appliance (cross
flowed) and to an indirect hot water tank / system with Fernox or other
similar corrosion inhibitor to prevent both corrosion and the formation of
limescale.
All Arada Boiler Stoves must be installed in an indirect
vented (also known as open vented) central heating system
Connecting pipes should be screwed to a maximum depth of 19mm for
the face of the tapping boss (1" BSP, parallel).
Remember to incorporate a drainage plug / tap at the lowest point of
the circuit to facilitate draining and flushing.
If a pipe-stat is not fitted to control the radiator circulation pump then
cold water corrosion may occur.
6.3
Water Connections
To connect the indirect hot water cylinder to the stove use 28mm copper
pipes. Ensure that the pipes rise continuously to the cylinder.
Ensure that runs are not too long (i.e. 6 metre maximum each for flow
and return). Install the cylinder above the level of the fire and as close to it
as possible. Within reason the higher the cylinder the faster the circulation.
Ensure no valves are present in the pipes.
In addition to providing hot water the primary circuit is essential in
providing a ’heat leak’ radiator to absorb excessive heat produced in the
event of a circulating pump shutting down.
Heat is produced in varying quantities while the stove is alight and care
must be taken to ensure that effective circulation can occur around the
primary circuit to carry the heat away thus preventing boiling. The heat
output of any radiator installed as a ’heat leak’ should not be less than 10
percent of the rated output of the appliance to which it is connected. It
