ABOUT THE APPLIANCE.

The corner oven appliance is a simple development of

the corner oil appliance incorporating a small oven built

directly on top of a corner oil appliance.

It is installed in the same way as the corner oil.

There are a few changes which are incorporated as

follows:-

1. The drip tray has an adjustable plate mounted to it

which can be used for levelling purposes.

Drip Tray and Adjuster Plate

Adjuster Plate Locking Fasteners

2. For maintenance purposes the oil control valve has

been mounted on a removable plate which allows the

valve to be removed from the appliance should the

need arise.

To remove the valve, first remove the left and right

hand side panels , then remove the oil feed pipe by

disconnecting at the descaling device and then undo

the straight compression joint and then remove the oil

feed pipe from the valve.

Undo the single locking screw, disconnect the oil flow

control rod and the thermostat control rod from the

oil control valve and the valve and plate should then

slide out.

Removable valve mounting plate.

As per the Corner Oil stove, standard deck flanges

and traditional chimney extensions can used above

deck but we do recommend the use of an anti

downdraft terminal.

As per the Corner Oil stove the appliance will provide

space or combined space and water heating plus

cooking on dry models and limited cooking on boiler

models.

There are two versions of the appliance, dry and wet.

The dry version is designed for space heating and

cooking.

The wet version is designed for space and water with

limited cooking.

On the wet, boiler version, there are x 1" BSP

female sockets for connections to be made to the

heating circuits as required at either side of the

appliance.

The boiler is high water content and suitable for

pumped or gravity systems, pressurised or open

vented, provided that they are correctly designed.

OPERATING PRINCIPLES.

The appliance is designed as a continuous running space

heater, which burns vaporized diesel fume in a

controlled manner utilizing a chimney to discharge the

products of combustion and a pumped or gravity fed

oil supply.

Once ignition has occurred oil goes into the pot where

it is vaporised and burned 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 for combustion

is drawn into the vaporizing pot by the natural action

of the negative pressure in the chimney and to allow

the chimney to work correctly it is essential that

there is adequate, unrestricted ventilation into the

area where the appliance is situated and the flue

system is warm enough to pull air through the burner

in the appliance.

The amount of vapour 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 vapour and air is required.

CONTROLS.

The output of the appliance is regulated by the amount

of oil for vaporization which is allowed to go into it and

this function is controlled by the -:

OIL CONTROL VALVE (O.C.V.), which is situated at

the right hand side of the appliance, behind the right

hand side panel.

Turning the knob anti clockwise controls the oil flow.

The knob is located at the top right hand side of the

appliance and is calibrated from off position (fully

clockwise) through 6 graduations to maximum.

Controls for the appliance will vary, depending on

which valve is fitted to it.

The valve could be an OCI ships valve or a Toby valve

and this should be specified with the order for the

appliance.

The control for the dry appliance comprises-:

1. Oil flow control only.

The boiler version has extra controls which are-:

1. Oil flow control

2. Thermostat control

3. Safety Stat reset control

The Toby oil control valve only is used on boiler

appliances. This valve has a built in, non electric,

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 similar safety stat,

which will shut the burner down, should the water

exceed 80 deg C.

The safety stat re set control is lifted to reset the

valve, should the stat trip.

The Toby valve has to be tripped into action by lifting

the trip button at the left hand side of the control

panel.

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.

With the increased flow of oil, extra heat is

generated, which in turn stimulates the chimney to

work harder and consequently draw more air into the

pot to maintain an adequate fuel air ratio.

Take care to make sure that safety and ventilation

issues are adequately addressed.

FUMES

When the appliance is first ignited, it may be

necessary to warm the chimney and the base of the

pot with a propane gun; this will get the cold air moving

in the stack and allow the burner to draw in.

Under non starting cold chimney situations, here are

the main causes of fume or smoke to leak from the

appliance.

• 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.

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

appliance on combustible materials and boat occupants.

Make sure that all combustibles are adequately

protected from the effects of heat radiation.

The appliance must stand on a fireproof base as per

the distance from combustibles table.

On appliances using the coal kit, the floor in front of

the appliance must have suitable fire protection

extending a minimum of 100mm in front of the

appliance.

The appliance has built in rear heat shields and when

the appliance is positioned in a suitable location there

must be a space of 25mm clearance beyond the outer

heat shield, to allow air to rise up and around the heat

shields.

The rear of the upper oven is insulated and the

insulation is covered by a metal heat shield type plate.

Do not remove the heat shields under any

circumstances.

BURNS.

During normal, day-to-day use, many parts of this

appliance, pipe work, and chimney can become too hot

to touch.

Where necessary, we recommend that suitable guards

be fitted, to provide adequate protection from the

heat generated by the appliance. Fireguards must

comply with BS6539.

Always use heatproof gloves when working on or near

to a hot appliance.

CLEARANCES FROM COMBUSTIBLES (APPLIANCE)

See table in 1 .

CLEARANCES FROM COMBUSTIBLES (FLUE)

See table in 1 .

VENTILATION.

Ventilation plays a vital role in the fitting and sighting

of any appliance.

The provision of ventilation for this appliance is

adequately covered by the requirements of the boat

safety scheme.

25-cmsq. Minimum permanent ventilation, directly to

outside air, must be provided for this appliance.

WARNINGS.

Never try to relight a hot appliance; wait until it has

cooled down.

Hot oil vapour is explosive.

Never try to light a flooded pot.

When attempting to light an appliance, 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 section.

The appliance must be securely fastened down so that

it can resist impact or collision and it must be level in

both directions.

The appliance must not be operated with the glass

front door opened or cracked, or without the lighting

port plug fitted.

Only Qualified persons can install unvented plumbing

systems.

A suitable and serviceable fire extinguisher should

always be readily accessible.

IMPACT RESISTANCE.

The appliance must be securely bolted down so that it

can resist impact or collision and it must be level in

both directions.

Two fixing brackets are provided; these should be

fitted over the oil drip tray up stand and fastened

down through the hole provided.

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.

It is obvious that on a boat all the above elements are

in short supply.

Normally, we have low flues which are small in

diameter and generally not very well insulated, coupled

with all these problems we have an additional 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

appliance is slowed down for all night burning, as the

flue gas cools down the chimney vacuum reduces and as

the chimney vacuum drops, the appliance may well

start to burn sooty. This problem is highlighted even

more during very cold weather when the chimney can

cool down even faster.

THE CHIMNEY RULES.

1. Always use a top outlet for flue pipe take off.

Never put any sharp bends in the flue.

(To

maintain a concentric fit, we will allow a slight

kick off the appliance and a similar kick into

the deck flange).

3. Always try to get the appliance as low as

possible in the boat, this will allow installation

of maximum length flue pipe.

. Always have two double walled, above deck

extensions, short for cruising and long (28inch

minimum) for mooring. Insulated extensions

are a thing of the future but it is possible to

fill the space using a vermiculite and cement

mix sealed off with flexible fire putty or heat

proof silicone.

5. Fit a rotary swinging cowl to each extension or

make one interchangeable.

6. Clean or have the chimney cleaned regularly.

(Frequency depends upon type of fuel and

length of time used).

7. Flue pipes should leave the appliance vertically

and go through the roof of the vessel

verticaly.

8. Under no circumstances should straight flue

pipes be wedged in to the stove flue collar

at an any angle less than vertical.

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 feet long in

10mm dia with insulated lagging.

TRIM.

A minimum pressure head of out 8" 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

appliance.

TANK. SEE FIG

If the appliance 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.

Do not use glass filter bowls, they are not acceptable

under the boat safety scheme.

Always add a suitable proprietary antifreeze additive

to the appliance fuel for wintertime running.

OIL LINE. SEE FIG

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.

Where oil lines go through bulkheads, use correct

bulkhead fittings.

The diameter of the oil line is dependant upon the

length of run.

At this point it is necessary to fit a remote sensing

fire valve, designed to shut off the oil supply, should a

fire occur near to the appliance.

If the bubble appliance 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. FIG

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 appliance 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 appliance 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. FIG

Two isolation valves are required, one fitted directly

into the oil control valve to allow you or the service

man to turn the oil off should the need arise, and one

on the oil tank fitted before the filter.

SLEEVING. FIG

Where the oil line goes through panels, a suitable

sleeve must be fitted and sealed with a suitable

sealant.

Try to use materials, which are easy to keep clean and

fireproof such as tiles, asbestolux, TAC board or

vermiculite boarding.

THE HEARTH.

The hearth must be-:

FLAT - SECURE - FIREPROOF AND LEVEL IN BOTH

DIRECTIONS.

See (Distance from combustibles.)

FIREPROOFING.

The vertical walls of the fireplace must be

fireproofed, suitable materials would be tiles,

asbestolux sheet, compressed vermiculite board.

APPLIANCE FEATURES.

The appliance has a base plate, which is designed to do

two jobs,

• It acts as a drip tray to catch any oil spill.

• It acts as a spacer to set the appliance at a

suitable distance from the vertical walls of the

fireplace to allow adequate cooling air to flow

around the oil valve.

FASTENING DOWN.

It is important to fix the base tray down to the

hearth but don’t drill through it as this will allow oil to

leak from it should a spill occur. Clips to go over the

top of the up stand are provided for this job.

SELECT LOCATION.

The appliance can be located in any suitable corner.

It and the flue system must be securely fastened, so

as to withstand the normal day-to-day situations,

which will be encountered in a narrow boat.

These could be-:

• Impact by other vessel.

• Impact into lock gate.

• The pitching and rolling effects of inland

water sailing.

• Etc.

There are two angle brackets provided with the

appliance, which hook over the front lip of the base

tray and are screwed down to the hearth.

The location must have adequate protection from the

effects of radiated and conducted heat as specified in

section and FIG1.

FIT OIL TANK. Fig

The oil tank will be fitted in the bow area and must

comply with the requirements of the boat safety

scheme. See schematic FIG .

RUN OIL LINE. FIG

Run the oil line and fit all the required components as

described in sec and shown in FIG .

TRIAL FIREPLACE ASSEMBLY.

The oil line and the fire valve sensor will have to pass

through the fireplace, make sure that you make

adequate provision for this and the remote sensing

fire valve.

TRY APPLIANCE IN POSTION.

Try the appliance in position and make sure that the oil

feed and remote sensing fire valve fit as required.

ESTABLISH FLUE POSITION.

Normally the appliance will be fitted in a corner, in a

suitable fireplace; this will predict the angle at which

the flue pipe will have to be fitted.

The flue pipe will normally run at a slight angle to allow

it to terminate through the ceiling, in a suitable

position.

It is important to make sure that the flue fits

concentrically at both the appliance end and as it

passes through the fire stop spacer and deck flange.

To achieve this the pipe will have to be marked out,

notched and re-welded. Make a template to work from.

When final fitting of the flue pipe occurs, make sure

that the decorative top frame is fitted to the

appliance, before the final fixing.

MARK OUT AND CUT THE ROOF PLATE.

FIT DECK FLANGE.

If you are going to use a standard deck flange for 6-

inch extensions you will have to cut off the lower

extension with a grinder to allow fitting of the fire

stop spacer.

The deck flange will be bolted to the roof plate with a

seal of silicone rubber applied between the joint.

The flue pipe provided with the appliance will be

marked and trimmed off 10mm below the top of the

deck flange to allow the flexible fire-cement to be

flaunched into a suitable taper.

The glass fibre rope will be wrapped around the flue

pipe and gently pressed down on to the fire stop

spacer, allow 10mm at the top of the joint and pack

the gap with the flexible fire cement which will form a

seal.

The deck flange will form the base for the traditional

chimney extension to be fitted.

FIT FIRESTOP SPACER.

The fire stop space will be fitted in between the deck

flange and the ceiling plate concentric to the flue

access hole cut in the roof plate of the boat.

It will provide heat protection for any combustible

materials located near to the through roof location.

The centre hole is cut deliberately undersize to

accommodate differing flue sizes and angles.

It will be necessary to open up the centre hole to fit

the flue pipe; this can be done by using the flue pipe

as a template and carefully marking round it.

File the excess material away with a rough rasp. (Do

this a little at a time to make sure that a good fit is

achieved.)

The top surface of the spacer may also need trimming

to provide a snug fit up to the inner surface of the

roof steelwork.

FIT CEILING PLATE.

The ceiling plate will be fitted inside the boat to finish

off the through roof fitting of the flue pipe.

It will be screwed up to the trimming timber via

countersunk wood screws.

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.

Installation of the wet appliance 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 appliance up to the heating circuit.

The appliance 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 appliances 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 appliance, 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 appliance via x 1 inch

BSP female sockets, welded into the boiler at the rear

top and bottom.

Alternative access to either side of the appliance,

allows the installer to fit the appliance 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 appliances, 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.

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 appliance and as close as possible to it,

obviously keeping horizontal runs as short as possible.

VENTING OF AIR. FIG 5

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. FIG 5

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

other devices that can be used to interfere with the

free flow of water.

PUMPED SYSTEMS. FIG 5

Always come off the appliance with 28mm copper for a

minimum run of 350 mm before dropping on to 22mm

hep 2o

To ensure suitable flow of water through the

primaries a suitable injector tee should be used.

Great care should be taken with the positioning of the

circulating pump and the feed and expansion tank to

make sure that the water flows where it should and

that over pumping does not occur.

The heating circuit must be piped in 22mm copper or

Hep 2o with 15mm stabs to radiators.

Where additional radiators are fitted as heat leaks,

the pipe work must be kept as short as possible, rise

on feed and fall on return.

SAFETY VALVE. FIG 5

A 1" safety valve must be fitted as close to the boiler

as possible (within 300mm) and the outlet from it must

be directed to a safe location so as not to present any

danger should the valve blow-off and exit steam or

boiling water.

Note, safe location could be through the side of the

boat, with a deflector to stop any horizontal emission.

WATER TREATMENT.

To reduce the build up of lime scale in the primary

circuit pipe work the temperature of the water should

not be allowed to exceed 65 Deg C and a suitable

water treatment should be added.

If the boat is to be left unattended the water, in the

heating system should also have suitable antifreeze

added or be drained down.

DRAIN DOWN. FIG 5

A drain down valve should be fitted at the lowest point

of the circuit.

CIRCULATING PUMP. FIG 5

On pumped systems make sure that the circulating

pump is fitted in such a way as to make it easily

replaceable, this means lock shielded valves at either

side and easy access.

If the appliance has been fitted to an existing heating

system, make sure that the system is adequately

designed and complies with the details specified in

this manual.

If the heating circuit does not comply, it must be

modified, before attempting to light the appliance.

no potential for air locking. (Kinks, wavy runs, and

sudden changes in level or slope).

ELECTRICAL.

Check for correct fusing, location and specification of

any isolation devices.

VENTILATION.

Make sure that adequate ventilation is provided in line

with boat safety scheme.

HYDRAULIC SYSTEMS. SEE FIG 5

Water systems should be pre-checked for leaks and

tests must be made to make sure that water will flow

freely through the boiler and that the boiler and pump

is vented and free from trapped air.

Make sure that the heat leak circuit is adequate and

unvalved.

CHIMNEY SYSTEM

Chimney heights must be a minimum of 1.8 meter for

low fire use and 2.2 meter for high fire use.

Check the appliance is fitted with adequate clearances

from combustibles.

Check that the combustion air restrictor is

functioning correctly.

DISTANCES FROM COMBUSTIBLES

Make sure that both the appliance and flue system

comply with the required distances from combustibles.

LIGHTING.

WARNING FOR BOILER APPLIANCES.

If the appliance is fitted with a boiler, air locks or

poor water flow through it may cause damage.

Make sure that the boiler has been vented of all air

BEFORE ATTEMPTING TO LIGHT THE

APPLIANCE.

Note; oven stoves are very efficient and as a

consequence of this the flue pipe is slow to heat

up. Most of the initial heat gets absorbed by the

oven therefore before attempting to light the stove

especially on a cold boat, it is advisable to pre heat

both the burner pot and the flue pipe to make sure

that the slug of cold air in the flue and appliance is

rising and will allow air for combustion to be pulled

into the burner pot. If the flue is not drawing air

and the appliance is cold, fumes may well leak from

the appliance and the ignition process can be long

winded.

Lighting the appliance takes a little time and patience;

the following procedure should be adopted.

Open the front door.

Remove the coal kit if it has been supplied with the

appliance.

Remove the inner mesh catalyser

Turn the oil on at full rate and allow oil to flow into

the bottom of the pot to form a pool about the size of

a small digestive biscuit and then turn the oil off.

Do not allow any depth of oil to build up.

Light a small piece of firelighter (about the size of a

pineapple chunk) and place it into the centre of the

pot.

Replace the lower burning ring, the mesh catalyser and

the coal kit and then leave the door slightly open

whilst the firelighter gets the oil going.

If fume leaks out of the appliance this is a sign that

the flue pipe is not hot enough and needs to be pre

heated.

After 30 to 0 seconds, you will notice the flame start

to establish itself and spread around the bottom of

the pot.

When this occurs, close the door and turn the oil on to

its minimum setting.

If the flame goes out or runs very sooty this is a sign

that the flue is not hot enough.

After two or three minutes the flame should then

slowly change from yellow into blue flame combustion

and settle down to a steady burn.

Note there may be the occasional growl or audible

vibration whilst the burner settles down into blue

flame combustion.

Allow the burner 10 – 15 minutes to stabilise and the

increase the flow of oil as required, moving by one

increment of the dial only.

Do not leave the appliance unattended during the

lighting and stabilising procedure.

COMMISSIONING THE HIGH AND LOW FIRE.

Adjustments should be made by reference to the oil

valve booklet supplied with the appliance

Allow at least one hour for the chimney and appliance

to warm up thoroughly before making any adjustments

to the high or low fire screws.

When the burner has established good blue flame

combustion turn it up to half output. (Setting 3 on the

fuel flow control knob) and let it stabilize.

Turn the appliance down onto minimum firing rate and

let it stabilize.

After stabilization there should be a dull red glow in

the catalyser with wispy blue flames flickering just

over the top of it, approximately level with the top of

the pot.

If the flame falls into a dirty rolling yellow flame and

the catalyser is not dull red then the low fire will need

to be increased until the burner can support the

required blue flame combustion.

When you are happy with the low fire, set the high

fire.

Turn the oil flow knob up to setting , let the flame

stabilize, and look at it, if it is stable and blue, turn it

up slowly using the control knob, letting it stabilize

after each movement,

if the flame starts to go yellow

with long flame combustion, it is running fuel rich

and

the high fire screw needs adjusting to reduce the flow

of oil. (Screw the adjuster screw in to reduce the high

fire oil flow.)

Before adjusting the high fire screw, turn the flame

down and let it stabilize in blue flame combustion,

adjust the high fire screw by half a turn in and try

turning the fuel flow up, if it is still fuel rich repeat

the process until the hire fire flame is running blue

with flicks of yellow in the tips.

On the Socomef pot, the high fire flame will be set

approx 0mm higher than the top of the pot.

CHECKING THE ACTION OF THE BUILT IN

THERMOSTAT.

Boiler appliances have a thermostat assembly attached

to the top of the oil control valve.

After the high and low fire has been set, check the

action of the thermostat and overheat stat.

Do this by turning off the circulating pump and putting

the appliance on to high fire.

As the boiler temperature increases the thermostat

will shut the appliance down on to low fire, because the

circulating pump is not working the boiler will carry on

increasing temperature, at approx 80 deg C the safety

stat will shut the oil valve down and the appliance will

go out.

If this does not occur there could be a fault on the

thermostat assembly.

If the system does not perform well check the

following-:

LACK OF PRESSURE RELEASE SAFETY VALVES.

FEED AND EXPANSION.

Is it fitted in the correct place?

1. RACING.

1. Audible vibrations generated by the flame caused

allowing by too much oil in the pot, too quickly.

1-1. Turn off the oil flow until the burner has settled

down to a steady burn rate and then turn the fuel on

again but don’t let the flame go out otherwise the

burner MUST be allowed to cool down fully before a re

ignition is attempted.

2. FLUE VACUUM.

1. The pot type burner is extremely sensitive to flue

vacuum variations.

2. Good combustion will not be possible unless our

instructions on chimneys and flue vacuum are followed.

See fig1

3. If the burner does not burn with a blue flame,

recheck the chimney vacuum and oil flow rate.

. If the burner does not run well check that the seals

in the appliance are good and that there is no ingress

of air into the appliance flue ways.

5. Check that the correct fuel oil is being used.

6. Check the levels.

3. BURNER RUNS SOOTY.

Comments made on this subject assume that the

appliance has been running normally for some time.

If the appliance soot’s up this indicates that there is

not adequate air for blue flame combustion or there is

an excess of fuel.

Check that the chimney is working correctly. (This

means pulling enough air into the burner to allow

correct blue flame combustion to occur.

Check that the fuel is the correct type and quality.

Check that the flow rates are correct.

Where burners are run at high fuel flow rates on low

chimney vacuums, long unsatisfactory yellow flame

combustion and bad sooting will occur.

To rectify this problem reduce the high fire flow rate

screw on the Oil Control Valve until blue flame

combustion occurs.

Never switch from low settings to high settings; a

longer burner life will be achieved if the regulator is

moved only by one number at a time leaving approx. one

minute between each setting change.

. BURNER DOES NOT LIGHT EASILY.

Read the instructions in the lighting section of this

publication.

5. OIL WILL NOT ENTER THE POT.

Is there oil in the fuel tank?

Has the fire valve tripped?

Has the isolation valve been accidentally turned off?

Is the oil turned on at the oil flow control knob on the

valve?

Is the oil feed pipe from the valve to the pot?

Blocked. (Unlikely)

Has the water stat tripped off on the aqua stat?

Has the aqua-stat been damaged by overheating.

To check this out, remove the aqua-stat from the

valve and remove the phial from the boiler, re cock the

valve and test fire the appliance. See Fig Toby Valve

document.

Note this type of damage is not covered by the

warranty.

6. OIL SMELLS.

Visual check on all joints for obvious leaks.

Check that the descaling lever packing gland nut is

adjusted.

7. DEFLOODING A FLOODED POT.

To carry out this procedure you will need -:

a. A small leak proof plastic bag.

b. A small sponge.

c. A larger plastic bag for disposal of the residue.

d. A pair of disposable plastic gloves.

If the pot becomes flooded, de flood it is as follows -:
