8.2.1 LPG Appliance (Non cooking appliance not room sealed)
All LPG appliances shall be room sealed with the exception of cooking appliances.
8.2.2a Use of non room sealed appliance (Non room sealed, non cooking appliance installed after the date specified.)
Exemption 11.25 allows the continued use of non room sealed LPG appliances installed before 03/01/00 providing certain conditions are met regarding the installation of those appliances.
8.2.2b Modifications or additions (Modifications or additions made after the date specified not on accordance with appliance manufacturer’s recommendations)
Modifications or additions to an existing installation shall be performed in accordance with the appliance manufacturers recommendations.
If there is evidence that an existing non room sealed appliance has been modified or added to after 03/01/00 and the modification or addition appears contrary to the manufacturers recommendations, documentary evidence may be required to support the claim for the exemption.
8.2.2c Gas or Paraffin Refrigerator in vessel with petrol engine (Pilot light/burner not completely enclosed)
Pilot lights and burners on LPG or paraffin refrigerators installed in vessels with a petrol engine shall be completely enclosed.
Petrol vapour is extremely dangerous. It would be difficult, but not impossible, for any gas refrigerator other than a room sealed appliance to be safety installed in a petrol engined boat in accordance with the manufacturers installation requirements.
8.2.2d Gas or Paraffin Refrigerator in vessel with petrol engine (Combustion air and combustion products not drawn/exhausted as specified.)
Combustion air and combustion products shall be drawn and exhausted through a suitable flame trap, or combustion air piped to the appliance from outside the vessel or from a point inside the vessel above the level of windows or other means of ventilation in the accommodation space.
A suitable could be made of non combustible and non corrosive material fitted with a wire gauze not less than 11 to the liner centimetre.
8.2.2e Gas or Paraffin Refrigerator in vessel with petrol engine (Combustion air not piped as specified)
If combustion air is not drawn through a suitable flame trap, it must be piped to the appliance from outside the vessel or from a point inside the vessel above the level of windows or other means of ventilation in the accommodation space.
Preferably the pipe should be directly connected to the air outside the vessel.
8.2.2f Catalytic Appliance (Does not comply with BS5258-11 or BS EN 449)
The requirements of BS 5258 –11 provide that the heater should be fitted with a guard which cannot be removed without the use of tools, the control tap should be clearly marked to show Off – IGNITE – ON . There should be s name badge fitted and any flexible rubber tubing should comply with BS3212 and not exceed 1m.
8.2.2g Flue/draught diverted (Not an approved type)
The flue and draught Diverter of existing appliances shall be of a type approved by the manufacturer.
No component of a flue system supplied as original equipment or as optional extra equipment by the appliance manufacturer should be modified or replaced without written approval from the manufacturer.
8.2.2h Flue/draught diverted (Not properly fitted and maintained)
The flue system must take the most direct practicable route consistent with structural stability, appearance and termination. An essentially vertical route from the draught Diverters is especially desirable.
Any joints in closed flues must be sealed so there is no possibility of flue gases discharging into the interior of the vessel.
Flues with draught Diverters need not be sealed providing there is a reasonable overlap of about 15mm at any joint.
All flues should be properly supported and secured to the permanent structure of the vessel.
Terminals must be connected to the flue system with a weatherproof joint and secured so there is no possibility of the terminal being forced into the flue pipe and causing an obstruction.
8.2.2I Flue Not of suitable materials
The material must be non combustible and capable of withstanding vibration from machinery or weather conditions.
Terminals are not to be fixed with pop rivets or other aluminium or lightweight fastenings.
8.2.2j Flue (Not effectively insulated)
The temperature of the gases passing through the flue may be extremely high depending on the fuel used and is sometimes above that required to set fire to wood and other flammable materials.
It is essential, therefore, that the flue is effectively insulated where it passes close to flammable fabric and structure so there is no risk of setting fire to any part of the boat.
8.2.2k Flue (Does not ensure safe transfer of gases to outside of vessel)
Flues must be of appropriate internal diameter to ensure safe transfer of gases to outside the vessel away from areas that could be enclosed by canopies.
8.2.2l Flue/Draught Diverter (Not fitted to fuel burning appliance which requires one)
Appliances designed for use exclusively with a flue, or draught diverter and flue, shall have one fitted.
8.2.2 Exemption Applied (11.25)
8.2.3 Test Fitting (No test fitting on appliance)
LPG appliances should include a test point fitting.
8.2.4 Exemption Applied (11.26)
Vessels manufactured prior to 3 January 2000 are not required to comply with that part of
Standard 8.2 which requires LPG appliances to include a test fitting.
8.2.5 Burner Flame Picture (Not Satisfactory)
A satisfactory flame picture shall be present at each appliance burner when all appliance burners in the system are operating at maximum rate.
8.3.1 Appliances (Not properly installed)
Appliances shall be properly installed and in accordance with the manufacturers recommendations for installation in vessels and shall be situated in sufficient space as instructed by the manufacturer, to prevent overheating of nearby surfaces.
8.3.2 Exemption Applied (11.27)
Vessels manufactured prior to 3 January 2000 and having woodwork and all other combustible materials including curtains adjacent to all appliances suitably insulated and protected against excessive heat or inherently flame retardant, or treated with a durable flame retardant are not required to comply with that part of Standard 8.3 which requires appliances to be situated in sufficient space, as instructed by the manufacturer, to prevent overheating of nearby surfaces.
8.3.3 Appliance (Not secured)
Appliances shall be secured against accidental movement and connected so that there is no undue stress on pipework and fittings. The appliance must be incapable of movement in any direction.
8.3.4 Appliance (Not connected to avoid undue stress on pipework & fittings)
Ensure that appliances are properly and correctly installed will prevent undue stress on the appliance pipework.
Signs of poor practice in this instance may be misaligned pipework, broken securing clips or insufficient securing arrangements for the appliance.
The appliance connector must never be used to retain the appliance in place.
8.3.5 LPG / Fuel oil appliance (Installed in petrol engine space)
LPG and fuel oil appliances shall not be installed in petrol engine spaces.
If petrol vapour is introduced to a point of ignition it will immediately ignite and the flame will track back to the source of the vapour. It could easily start fires along that route and will almost certainly result in serious fire or explosion when the flame reaches the source of the vapour.
8.4.1 Gimballed cooking appliance (Not secured at all angles of heel)
Gimballed cooking appliances shall be secure at all angles of heel.
8.4.2 Materials in vicinity of cooking appliance (Combustible and not protected as specified)
Materials in the vicinity of cooking appliances shall be non combustible or protected with a finish of class 1 surface spread of flame rating as specified in BS476 – 7.
Materials in the vicinity of cooking appliances can be inherently non combustible or a non combustible shield or barrier can be secured between the appliance and any combustible material. It would be good practice to have a ventilated air space of not less than 25mm between the appliance and the combustible surface.
8.4.3 Combustible & unprotected materials (Distant from cooking appliance not as specified)
Combustible materials and materials without a class 1 surface spread of flame rating shall not be placed within the following distances of cooking appliances:
400mm above the cooking appliances for horizontal surfaces when the vessel is upright.
200mm above the cooking appliance for horizontal surfaces when the vessel is heeled to 30o
125mm horizontally from the cooking appliance for vertical surfaces
8.4.4 Exemption Applied (11.28)
Vessels manufactured prior to 3 January 2000 and having woodwork and all other combustible materials including curtains adjacent to all appliances suitably insulated and protected against excessive heat or inherently flame retardant, or treated with a durable flame retardant are not required to comply with the distance measurements applied to combustible materials and materials without a class 1 surface spread of flame rating, or the distance measurements applied to curtains and other suspended textile materials, in Standard 8.4.

8.4.6 Exemption Applied (11.28)
Vessels manufactured prior to 3 January 2000 and having woodwork and all other combustible materials including curtains adjacent to all appliances suitably insulated and protected against excessive heat or inherently flame retardant, or treated with a durable flame retardant are not required to comply with the distance measurements applied to combustible materials and materials without a class 1 surface spread of flame rating, or the distance measurements applied to curtains and other suspended textile materials, in Standard 8.4.
8.5.1 Flame supervision devices (Not fitted to appliance burners, ignition burners and pilot)
Appliance burners, ignition burners and pilot lights shall be fitted with flame supervision devices that completely close the LPG or fuel oil supply.
8.5.2 Exemption Applied (11.29)
Vessels manufactured prior to 3 January 2000 are not required to comply with Standard 8.5
which requires a flame supervision device to be fitted to all appliance burners provided that
such devices are fitted to all:
– catalytic type appliances
– appliances with a pilot light
– appliances with a continuously burning flame
8.6.1 Water inlet to instantaneous water heater (Not piped directly from cold water supply)
Instantaneous water heaters are designed to raise the temperature of water supplied to them rather than heat the water to a pre determined level.
If the supply were taken from the hot water system, there is a dangerously of producing dangerously hot water, even steam if pre heated water is admitted to the appliance.
8.7.1 Fuel Oil Appliance (Not applicable)
8.7.2 Fuel Oil Appliance (Not applicable)
8.7.3 Fuel Oil Appliance (Not applicable)
8.7.4 Fuel Oil Appliance (Not applicable)
8.8.1 Flue components (Not properly installed)
Flue components on room sealed appliances including ductwork and terminals shall be installed in accordance with the appliance manufacturer’s recommendations for installations in vessels.
Where the appliance manufacturer’s recommendations do not exist or are not available, installations should be in accordance with equipment / component manufacturer’s instructions or appropriate codes of practice.
8.8.2 Flue terminal / air inlet (Positioned within 500mm of specified locations)
The position of terminals must be such that flue gases cannot re-enter the boat through any opening or fuel vapours cannot enter the combustion chamber of the appliance by being drawn in through the air inlet being too close to a source of fuel vapour.
Flue terminals and air inlets shall not be positioned within 500mm of a ventilator, opening port, hatch, window, refuelling fitting or fuel tank vent outlet.
8.8.3 Flue / Flue terminal (Does not ensure safe transfer of gases to outside of vessel)
Flues and flue terminals shall ensure safe transfer of gases to outside the vessel.
8.8.4 Flue terminal (Not outside the vessel away from areas that could be enclosed by canopies)
The flue terminal must be sited outside the vessel. Terminating flues in areas that could be enclosed by a canopy is not permitted.
When a canopy is elected, the space it encloses is regarded as not being outside the vessel irrespective of how many openings there are between the canopied area outside the vessel.
8.8.5 Flue terminal (Not in a position that minimises risk of damage)
Flues and flue terminals shall be in a position that minimises the risk of accidental damage.
8.9.1 Fixed ventilation (Not in accordance with BS 5482 – 3)
Adequate fixed ventilation shall be provided in accordance with the requirements of BS5482 –3 in vessels in which LPG or other fuel appliances are used.
Ventilators must not be of the type which cannot be closed. Doors, windows and hatches etc. That can be fully closed not be included in the ventilation calculations. The presence of any device, which would reduce the clear air opening such as filters or insect screens, should be taken into consideration.
The formula used to calculate ventilation is as follows:
Minimum effective area = {2200 x U} + {650 x P} + {440 + F}
Where:
U = input rating for all unflued appliances {eg cookers} in kWs
P = number of persons for which the accommodation space is designed
F= input rating for all open flued appliance {in kW}
The minimum ventilation area shall be not less than 4000mm sq.
The ventilation should be divided equally between high and low level.
Ventilators should be weathertight to cater for the worst conditions likely to be encountered. Vessels which regularly proceed to sea and would likely experience severe weather conditions may have ventilators which can be closed to prevent the ingress of water in such conditions.
8.9.2 Ventilator (No warning notice displayed as specified)
On sea going vessels equipped with closeable ventilators a warning notice shall be attached on or near to all non-room sealed appliances. The wording of the notice should state:
“WARNING – Open ventilator(s) before use”
