Due to the gradual introduction of European
Chimney Standards chimneys will be specified
according to their performance designation as
defined in BS EN 1443 that covers the General
Requirements for chimneys. The minimum
performance designation required for use with solid
fuel burning stoves is T450 N2 S D3.
The flue and chimney installation must be carefully
checked by a competent person before fitting the
stove to ensure it is suitable and will work safely.
If the chimney is old (ie built of brick or...

INSTALLATION INSTRUCTIONS 
The expansion tank should have a capacity of at
least 7 % of the systems water capacity. The cold
water feed pipe should be at least 22mm diameter.
There must not be any shut off valves in the circuit.
Pipes should be run to avoid air locks. A spring
safety valve should be fitted to the expansion pipe
close to the boiler.
It is often possible, and is good practice, to utilise
the primary flow and return as part of the safety
circuit. The ball valve...

In the morning
•Open the air control fully until embers begin 
to glow brightly and place pieces of fuel on 
the fire until it is well established.
WARNING:When wood is burnt slowly in a
closed appliance it produces moisture and tar,
which will create condensation and deposits in the
chimney. This effect can be minimised by burning
hard for a short period, about 20 minutes, twice a
day. It is usually convenient to do this morning and
night.
Note: To avoid chimney problems your fire should
not be burnt...
