ABOVE DECK EXTENSION.
A traditional above deck extension can be fitted in line
with normal practice.
We recommend that a short extension is used for
cruising and a min 28” extension is used when mooring.
In each case we recommend the use of a rotating cowl
to minimise the effects of down draught.
Fit the side panels 1 x left and 1 x right hand sides.
Fit the front fender.

PREAMBLE.
Installation of the wet stove will be the same as the
dry except that when dealing with the location an
extra element comes in to the equation and that is
connecting the stove up to the heating circuit.
The stove has a fully integral, powerful boiler, which
forms the outer sides of the triangular shape and can
be fitted to open vented or pressurised systems.
When connecting stoves to pressurised systems make
sure that the Toby oil control valve and matching aqua
stat are fitted.
Before designing the fireplace, take great care about
making provision for the boiler connections and
remember that the whole essence of the Corner
Bubble is to make the finished job look like a piece of
integrated design.
To facilitate removal of the stove, make sure that
there is
EASY ACCESS TO THE BOILER UNIONS.
EASY ACCESS TO THE DRAIN DOWN VALVE.
EASY ACCESS TO THE OIL CONNECTION.
EASY ACCESS TO THE ISOLATION VALVE.
Water can be connected to the stove via 4 x 1 inch
BSP female sockets, welded into the boiler at the rear
top and bottom.
Alternative access to either side of the stove, allows
the installer to fit the stove in either port or
starboard locations.
Make sure that the vertical sides of the fireplace can
easily accommodate the pipe work.
When installing water heating Bubble stoves, the
space heating output will be reduced.
The boiler is high water content and suitable for
pumped or gravity systems both open vented or
pressurised.
If you are not suitably qualified, arrange for a heating
engineer to do the design and fitting work for you.
See FIG 5 for schematic layout.
CALORIFIERS.
Indirect calorifiers must be used on gravity or pumped
systems.
If you are going to install a gravity system you must
make sure that you purchase a special calorifier with a
28 mm internal diameter coil,
don’t be put off by
suppliers who say that they have 28mm connections
which are adequate, they are not as effective.
On gravity systems the calorifiers must be located
higher than the stove and as close as possible to it,
obviously keeping horizontal runs as short as possible.
VENTING OF AIR.
Gravity or Pumped systems can be fitted with open
vented or pressurised systems.
If open vented systems are used the feed and
expansion tank must be as close as possible to the
boiler and be fitted at the highest part of the circuit.
Consult an experienced boat-heating engineer for
advice on feed and expansion tanks.
To vent the system of air use automatic air vents on
all possible air lock locations.
PIPE WORK.
All gravity pipe work must rise on flow and fall on
return and be a minimum of 28mm dia. (35mm dia
preferred)
To reduce resistance to flow-:
•
Use swept bends, do not use elbows.
•
Use copper pipe work.
•
Use high water content radiators.
The primary circuit must have a total length of not
more than 6 meters otherwise the recovery time of
the calorifyer will be increased beyond an acceptable
period of time.
Primary circuit pipe work must not have valves or
