OPERATING INSTRUCTIONS
clear the sides of the fire box when removed.
The Island II - BP baffle consists of two firebricks which rest on the
central bracket (part BP077) and the two side bricks. The central
bracket rests on top of the rear bricks and slots into the hole at the
top face of the stove between the airwash tubes. To lower the baffle
bricks, push a brick up towards the topmost corner of the stove, and
lower down diagonally.
The Island II -BP also has an upper baffle plate that rests centrally on
top of the air wash tubes and locates into the hook at the top of the
front of the firebox.

FLUE SWEEPING
When installing your Charnwood into an existing brick flue that has
previously served as an open fire, it is possible that the higher flue
gas temperature from a stove may loosen soot deposits with the
consequent risk of flue blockage. It is therefore recommended that
the flue be swept a second time within a month of regular use after
installation.
Your Charnwood flue should be swept at least twice a year. Where
the top outlet or vertical rear flue connector is used it will generally
be possible to sweep the flue through the appliance.
First remove the upper and lower baffles. Then sweep the flue
ensuring that soot is removed from all horizontal surfaces after
sweeping.
In situations where it is not possible to sweep through the appliance
the installer will have provided alternative means, such as a flue
access door.
After clearing any soot from within the stove, replace the baffle (see
Fig. 5 ).
It is important to use the correct flue brush for the flue size, different
types of sweep’s brushes are available to suit different flue.
For prefabricated insulated flues the manufacturers instructions with
regard to sweeping should be consulted.
TROUBLE SHOOTING
Fire Will Not Burn
Check that:
a) the air inlet is not obstructed in any way,
b) flues and flue are clear,
c) a suitable fuel is being used,
d) there is an adequate air supply into the room,
e) If an extractor fan is fitted, that it is not causing lack of flue draft
when operating.
f) there is sufficient draw in the flue. Once the flue is warm a draught
reading of at least 1.25 mm (0.05 in.) water gauge (12Pa) should be
obtained.
Blackening of Door Glass
Differences in flue draughts mean that the best settings of the air
controls will vary for different installations. A certain amount of
experimentation may be required, however the following points
should be noted and with a little care should enable the glass to be
kept clean in most situations:
a) Wet or unseasoned wood, or logs overhanging the front fence will
cause the glass to blacken.
b) The airwash relies on a supply of heated air to keep the glass clean,
therefore, when lighting the stove allow the firebed to become well
established before closing the air control. This may also be necessary
when re-fuelling the stove.
c) When re-fuelling keep the fuel as far back from the front fence as
possible, do not try to fit too much fuel into the firebox
d) Do not completely close the air control.
It is always more difficult to keep the glass clean when running the
stove very slowly for long periods.
If blackening of the glass still occurs check that all flue connections
and the blanking plate are well sealed. It is also important that the flue
draw is sufficient and that it is not affected by down-draught. When
the flue is warm a draught reading of at least 1.25 mm (0.05 in.)
water gauge (12Pa) should be obtained. Some blackening of the glass
may occur below the level of the fuel retainer. This will not obscure
