THE FOLLOWING NOTES PROVIDE INFORMATION
FOR INSTALLATION OF THE FOLLOWING
APPLIANCES.
Boat Bubble No 1, Dry Small and Large Boiler Stoves

FITTING OPTIONS.
There are normally three different situations that the
installer may be faced with-:
A new build installation.
An established boat installation, (which has not had a
oil stove fitted).
A replacement installation, where there has been a
solid fuel stove fitted previously.
Each of the situations will present differing problems
which will be-:
Where to locate the stove.
How to deal with fireplace design.
Where to locate the oil tank.
How to get an oil supply to the stove.
How to fit the chimney.
How to connect water to the stove.
How to disconnect and remove the stove,
easily.
The new build situation should be the easiest.
The established boat situation will require careful
attention to the sighting of the stove in relation to
flue positions and existing fittings positions.
In replacement situations it may well be necessary to
blank off the existing through roof flue position and
cut a fresh one to suit the new location.
ABOUT THE STOVES
The stove is a space heater, which burns diesel oil in a
controlled manner utilizing a chimney to discharge the
products of combustion.
The stove generates heat from burning oil mixed with
air in a vaporizing pot located in the bottom of the
stove.
Once ignited, oil goes into the pot at a steady and
controlled rate via gravity flow, metered by the OIL
CONTROL VALVE the oil flow can be controlled from
minimum to maximum or any setting in between
determined by where you set the oil flow control knob.
Air is sucked into the pot by the natural action of the
negative pressure in the chimney and to allow the
chimney to work correctly it is essential that you have
adequate, unrestricted ventilation into the area where
the stove is situated.
The amount of oil that can be successfully burned is
directly proportional to the amount of air that the
chimney can draw into the pot and so to achieve
adequate combustion a balanced and appropriate flow
of both oil and air is required.
The stove will provide space or combined space and
water heating.
There are three versions of the stove
Space heating only.
Space heating and a small boiler
Space heating and a large boiler.
On the boiler versions there are 2 x 1" BSP female
sockets for water connections to be made.
Both boilers are high water content and suitable for
pumped or gravity systems, pressurised or open
vented, provided that they are correctly designed.
The stove incorporates a removable front apron, which
on manual ignition stoves is used to gain access for
lighting.
On the right hand side of the stove is a small lever
which should be rotated occasionally to descale the oil
inlet pipe.
The stove must not be operated with the glass front
door opened or cracked, or without the lighting port
plug fitted.
The door glass may require light cleaning occasionally
depending upon the continuous running time of the
stove.
The stoves must be securely bolted down so that it
can resist impact or collision and it must be level in
both directions.

4
The top of the stoves can be used for warming and
cooking.
Some stoves can also be supplied with or without a coal
kit.
Just like a solid fuel stove, coal effect will only be
available when the stove is running at maximum or near
maximum performance which is 4kW OR 14,000 B.T.U,
s PER HOUR.
Suitable deck flanges and flue systems must be used.
We strongly advise the use of a suitable anti
downdraft terminal.
CONTROLS
The output of the stove is regulated by the amount of
oil allowed to go into it and this function is controlled
by the -:
OIL CONTROL VALVE (O.C.V.),
Turning the knob anti clockwise controls the oil flow.
Controls for the stove will vary, depending on which
valve is fitted to it.
The valve could be a ships valve or a Toby valve.
The control for the dry stove comprises-:
1. Oil flow control only. (Ships Valve)
The boiler version has extra controls which are-:
1. Oil flow control
2. Oil valve trip lever
3. Thermostat control
4. Overheat device with manual re-set.
The Toby oil control valve used on boiler stoves has a
modulating thermostat control, which will put the fire
on to low fire when the target temperature has been
achieved.
In addition to this there is also a device which will
shut the burner down, should the water exceed 90 deg
C., the device can be reset should it trip off.
The Toby valve has to be tripped into action by lifting
the trip button.
The flow of oil into the pot can be adjusted via the
knob on top of extension rod rising up from the oil
control valve.

2. .S SA AF FE ET TY Y. .
Take care to make sure that safety and ventilation
issues are adequately addressed.
FUMES
Always fit a suitable Smoke and Carbon Monoxide
alarm.
Make sure that the function is checked on regular
basis.
Fit the alarms in such a position that in the event of
an alarm being triggered the noise from it will wake
you up should you be sleeping.
Here are the main causes of fume or smoke to leak
from the stove.
The chimney is blocked.
There are too many bends in the chimney.
The above deck chimney extension is not high
enough.
The boat is moored in a position near to high
buildings or trees and downdraughting is
occurring.
The chimney is not airtight.
There are unusually strong cross winds
If downdraughting occurs turn the appliance off until
the winds subside.
FIRE
Fire can be caused by a variety of potential danger
points and because of the space limitation on boats;
this risk is ever present and must be adequately
assessed.
The main danger is the effects of heat from the stove
on combustible materials and boat occupants.
Make sure that all combustibles are adequately
protected from the effects of heat radiation.
The stove must stand on a fireproof base of minimum
thickness 30mm.
Floors in front of the stove must have suitable fire
protection.
Built in stove heat shields should not be removed
under any circumstances.
BURNS
During normal, day-to-day use, many parts of the
stove, pipe work, and chimney will become too hot to
touch.
These hot surfaces must be adequately protected to
prevent anyone falling on to, or touching them.

5
Suitable fireguards for the appliance and chimney
must be fitted.
Fireguards must comply with BS6539.
Always use heatproof gloves when working on or near
to a hot stove.
CLEARANCES FROM COMBUSTIBLES
The stoves must be fitted in line with the distances
specified in the table.
All hearths and fireplaces must be made from non-
combustible materials.
CLEARANCES FROM COMBUSTIBLES-FLUE PIPES
Flue pipes must be fitted in line with the distances
specified in the table.
Any combustible materials within the specified
distances from the stoves must be protected by a
suitable heat shield.
Protection can be gained by the use of -:
Sheet metal heat shields and spacers.
Heat resistant boards such as TAC board.
Combustible materials can be-:
Wooden furniture.
Curtains.
Wooden panels or frames adjacent to the flue
pipe or where it passes through the deck of
the boat.
Carpet or flooring close to the stove.
Items near to the stove, which could fall onto
it and ignite, should the boat suffer a slight
impact or collision.
VENTILATION.
Ventilation plays a vital role in the fitting and sighting
of any stove.
The provision of ventilation for these stoves is
adequately covered by the requirements of the boat
safety scheme.
25cm2 minimum permanent ventilation, directly to
outside air, must be provided.
FLOODED VAPOURIZING BURNER POTS.
When attempting to light a stove, make sure that the
pot is not flooded with oil by looking into the base of
the burner.
If it is flooded remove the excess oil as per
instructions in the faultfinding manual.
Never try to relight a hot stove; wait until it has
cooled down.
Hot oil vapour is explosive.
Never try to light a flooded pot.
SECURELY FIX THE APPLIANCE
The stove must be securely fastened down so that it
can resist impact or collision and it must be level in
both directions.
Level the stove in both directions when the vessel is
midway between its maximum and minimum trim
conditions.
Bubble stoves must not be fitted if the maximum
angle of trim exceeds 1 deg forward to aft or port
to starbord.
The stove must not be operated with the glass front
door opened or cracked, or without the lighting port
plug fitted.
Qualified persons can only install unvented plumbing
systems.
A suitable and serviceable fire extinguisher should
always be readily accessible.

3. .C CH HI IM MN NE EY Y
This is the one of the most interesting problems the
installer has to deal with and as the chimney affects
most aspects of running the stove, we take time here
to list the following information for your
consideration.
The power, ( suck or vacuum the chimney can develop )
depends upon the following-:
THE HEIGHT.
THE DIAMETER.
THE TEMPERATURE OF THE GASSES IN IT.
THE RESISTANCE OF THE INNER SURFACE OF
THE FLUE PIPE OR PIPES.
THE TYPE OF TERMINAL.
THE PREVAILING ATMOSPHERIC CONDITIONS.
It is obvious that on a boat all the above elements are
in short supply.

6
Normally, we have low flues which are small in
diameter and generally not very well insulated, coupled
with all these problems we have an other one, which is
that the boat moves across constantly changing
surroundings, through locks, into headwinds and
crosswinds, all creating major opportunity for down
draughting to occur.
Any bend in any part of the chimney or roughness on
the internal chimney wall will slow down the velocity of
rising gases and reduce the effectiveness of the
chimney.
Any slight reduction in the flue gas temperature will
reduce the chimney vacuum or pull, hence when the
stove is slowed down for all night burning, as the flue
gas cools down the chimney vacuum reduces and as the
chimney vacuum drops, the stove may well start to
burn sooty. This problem is highlighted even more
during very cold weather when the chimney can cool
down even faster. In these situations careful
attention to servicing and low fire setting is essential.
THE CHIMNEY RULES.
1. Always use a top outlet for flue pipe take off.
2. Always try to get the stove as low as possible
in the boat, this will allow installation of
maximum length flue pipe.
3. Clean or have the chimney cleaned regularly.
(Frequency depends upon type of fuel and
length of time used).
4
4. .F FU UE EL LS SU UP PP PL LY Y. .
There are several problems relating to diesel fuel
supply, which need be adequately addressed.
WAXING
Cold weather waxing or thickening alters the flow
characteristics of diesel.
An adequate fuel feed supply can turn into an
inadequate one when the temperature starts to fall.
The worst scenario is fuel feed pipe 50-60 feet long in
8mm dia pipe.
The best-case scenario is a fuel pipe 4 feet long in
10mm dia with insulated lagging.
AIR LOCKS
Air lock in oil feed pipework must be avoided.
The pipe work must slope down to the appliance and be
clipped level at 500mm intervals to prevent sagging.
Any rises in the pipework will cause air locks on
commissioning and after future oil run out situations,
if it is not possible to run the pipework in a steady
slope then where changes occur a vertical venting leg
should be fitted.
TRIM
Bubble stoves must not be fitted if the maximum
angle of trim exceeds 0.75 deg forward to aft or
port to starbord.
Level the stove in both directions when the vessel is
midway between its maximum and minimum trim
conditions.
A minimum pressure head of 10" is required.
This head is measured from the base of the oil tank to
the top of the oil control valve. In some cases this
head can be affected by the ballast or trim of the
boat.
Take great care to try out all the different ballast
and trim possibilities to make sure that adequate oil
feed is always available at the outlet end of the fuel
pipe before it enters the oil control valve at the stove.
TANK
If the stove is fitted at the bow of the boat, a bow
tank is recommended.
The tank should comply with the requirements of the
boat safety scheme and have-:
A conveniently sized filler
A means of venting.
A conveniently located, easily visible, contents
gauge.
An isolation valve
An easily replaceable cartridge filter.
A suitable and substantial water trap
Do not use glass filter bowls, they are not acceptable
under the boat safety scheme.
Make sure that you fuel supplier supplies you with
appropriate fuel for wintertime running.
OIL LINE
The oil feed line starts after the fuel filter and
proceeds to the point of entry, which is where the oil
line goes into the cab or saloon of the boat.

7
The diameter of the oil line is dependant upon the
length of run. See 3-2 on waxing and make sure that
you have suitably sized compression fittings available.
At this point it is necessary to fit a 60 DEG C, remote
sensing fire valve, designed to shut off the oil supply,
should a fire occur near to the stove.
If the bubble stove is fitted up to the first bulkhead
it will be necessary to fit the isolation valve outside
the cabin or saloon of the boat.
WATER CONTAMINATION
Because of the high risk of fuel contamination with
water, we strongly recommend the fitting of a high
volume water trap, in the oil supply line.
REMOTE SENSING FIREVALVE
The fire valve has a capillary tube on the end of which
is a temperature sensitive phial, run the capillary tube
with the oil line up to the stove and carefully fit the
sensing phial 15mm pipe clips in front of the drip tray
on the fireplace hearth, directly in front of the
combustion air restrictor.
Before it is fitted try the fender on the stove to
make sure that the fender does not fowl the sensing
phial.
The sensing phial may be visible through the bottom of
the fender, to mask it, paint it with matt black paint
available from our sales desk.
When fitting the fire valve make sure that where the
capillary and oil line go through the bulkhead in
separate sleeved tubes, so that the capillary can be
withdrawn separately should it ever need replacing.
For fitting of long oil feed lines which pass through
bulkheads and various other parts of the boat it may
well be necessary to fit more than one fire valve,
especially where the oil line passes through an area
where a fire could occur i.e. kitchen area etc.
ISOLATION VALVES.
Two isolation valves are required, one fitted directly
into or close to the oil control valve to allow you or the
service man to turn the oil off should the need arise,
and one fitted directly into the oil tank before the
fuel filter.
Always turn off the oil isolation valve serving the
appliance before leaving the vessel unattended.
SLEEVING.
Where the oil line goes through the boat
superstructure a suitable bulkhead fitting must be
used.
OVERBOIL OR OVERHEAT PROTECTION OF THE
APPLIANCE.
Where Toby aquastats have not been fitted to the oil
control valve, an additional 90 DEG C, remote sensing
fire valve fitted either into, or close to the oil control
valve may be fitted.
The sensor from this valve has to be attached to the
water jacket or the hot outlet pipe from the boiler.
The valve is calibrated to shut the oil supply down
should the water temperature exceed 90 Deg C.
There is a re set button which needs to be pressed in
to re set the valve after it has tripped off.
5
5. .F FI IR RE EP PL LA AC CE E. .
Always fit the stove on a suitable drip tray.
The possibility of oil drops leaking from the stove
must be considered, a suitable oil drip tray must be
fitted and designed in such a way, as it will contain any
oil leaks or drips.
Normally the tray will cover the footprint of the
stove, the oil valve and isolation device.
It will be oil tight and have a vertical upstand of at
least 30mm. This should give a minimum containment
volume of 2 litres.
It will be securely fastened down to the vessel and
the appliance must be securely fastened down to the
oil drip tray.
Make sure that drip trays are tested to ensure that
they do not leak when filled with oil.
Use materials, which are easy to keep clean and
fireproof such as tiles, asbestolux or vermiculite
boarding.
The hearth must be-:
FLAT - SECURE - FIREPROOF AND LEVEL IN BOTH
DIRECTIONS.
The vertical walls of the fireplace must be made from
fireproof materials.
Use fireproof, rockwool infill behind the fireplace
panels to protect any combustible insulation materials
such as spray foam.
