Do Not
±
Under any circumstances connect the stove to a sealed (pressurised) heating system
or an unvented HW cylinder
Do Not
±
Link the stove into a heating or hot water system with an existing boiler without the
use of suitable equipment such as a neutralizer. When fitting this type of system the neutralizer
manufacturer
¶
s instructions must be followed.
Do
±
Fit an open cold feed and header expansion tank with separate cold feed and vent pipes.
The cold feed and vent pipes must be unvalved. The open vent pipe should have a diameter of
22mm and rise continuously from the boiler.
The gravity circuit should connect to a domestic indirect hot water cylinder of minimum 135lt
capacity, using 28mm flow and return pipes, rising continuously from the boiler to the cylinder.
Any nominally horizontal runs of gravity pipework should slope upwards at not less than 1:30.
The base of the hot water cylinder should be located at least 150mm above the top of the stove.
The gravity circuit must not contain any shut off valves and should be fully lagged to minimise
heat loss. The pipes should not exceed 7.8 meters (25ft) in length to/from the cylinder. In
general, the shorter the run of pipework the less heat loss and the more efficient the water
heating.
