Charnwood Country 12 Mk2 - Manual (Page 8)

The hot water system should be a
gravity circuit and must be correctly
vented as shown in Fig. 4.
The steel boiler together with a
double feed indirect hot water storage
cylinder to BS:1566 part 1 should be
used in most situations, unless the
appliance is to be fitted in a soft
water area in which case the stainless
steel boiler may be used with a direct
hot water cylinder.
All pipework in the primary circuit
must be 28mm diameter and the flow
pipe must rise continuously from the
boiler to the open vent.
If an indirect cylinder is used then
the primary circuit should be filled
with a suitable inhibitor to prevent
the build up of scale and corrosion.
FITTING THE
OPTIONAL ADD-IN
BOILER
The boiler replaces the rear firebrick.
On the Country 8 the boiler also
replaces the throat plate, on the
Country 12 a special throat plate,
(part no. 010/BV35), is required.
Before fitting the boiler, remove the
front firebars, the side and back fire
plates, the throat plate and the rear
firebrick. Knock out the knock-outs
for the boiler tappings in the back of
the firebox.
Remove the backnuts and fibre
washers from the boiler tappings and
fit the boiler into the appliance. Place
the fibre washers over the tappings
on the outside of the appliance and fit
the backnuts, ensuring that the boiler
is held tightly against the rear inside
face of the appliance and that the top
edge of the boiler is level or runs
uphill to the flow tapping.
Gaps between the boiler and the
firebricks should be filled with fire
cement. Replace the back fireplate,
the side fireplates and the front
firebar. On the Country 12, fit the
new throat plate.
Connect the boiler to the heating
system ensuring that the flow pipe
rises from the boiler. Fill the system
with water and check for leaks.
CONNECTIONS TO
FLUES
There are several ways of connecting
the stove to the flue. These are
illustrated in figures 5 to 8.
If the vertical rear flue connector is
used and no boiler is fitted then the
