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).

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 pipe work 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 pipe work will cause air locks on
commissioning and after future oil run out situations,
if it is not possible to run the pipe work in a steady
slope then where changes occur a vertical venting leg
should be fitted.
TRIM
Bubble appliances must not be fitted if the
maximum angle of trim exceeds 0.75 deg forward
to aft or port to starboard.
Level the stove in both directions when the vessel is
midway between its maximum and minimum trim
conditions.
A minimum pressure head of 254mm (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.
The diameter of the oil line is dependent 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. 5. Make sure that you
have purged the oil feed line of all air and there is a
steady and constant flow of oil available at the inlet to
the oil valve. Make sure that all or any oil isolation
devices are turned to the on position. Remember that
the oil valve needs a min head of 300mm for gravity
feed. When feeding from rear tanks with appliances
fitted forward always be aware of the forward – aft
trim of the vessel.
Do not use symphonic oil feeds to Bubble Appliances,
oil should be fed by gravity or pumped via an
appropriate pressure pump = head pressure less than
99mbar.
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.
