Gas
Safety in Caravans
Caravans must be built and regularly maintained, and gas appliances
installed in accordance with the safety requirements of British
Standards in order to help minimise risk to you and your family.
All Gas appliances
in your caravan should be serviced annually to keep them in a safe
and efficient condition. Properly maintained appliances are safe
in use and should be no cause for concern.
The service should include:
Ventilation check (air inlets are clear and adequate)
Flue check (smoke spillage test)
Appliance safety devices are working correctly
Appliances are safe for further use
A check for gas leaks and condition of pipework and hoses
LPG
Gas Installation Standard EN1949
LPG gas installation standard EN1949 comes into effect from the
beginning of September 2003 (all 2004 models) for NCC certified
caravans and motor homes. At present users require a regulator for
each gas type they use, 28mbar for Butane and 37mbar for Propane.
All models built after September 2003 must be fitted with an EN
12864, Annex D regulator by the manufacturer. In most cases this
will be fitted to the bulkhead or gas bottle locker wall.
Will the customer need different pressure regulators, one Butane
and one Propane?
The EN 12864, Annex D regulators fitted will be 30mbar to standardise
with Europe and the new regulator is designed to supply Propane
or Butane at this pressure.
How will I connect
the new regulator to the gas cylinders?
3 new hoses (pigtails) are available from Burdens for the UK market,
one for Calor 4.5 kg Butane (hexagonal nut), one for Calor 3.9kg
& 6kg Propane and one M20 x M20 with an adapter for Campingaz
cylinders. For 20mm & 21mm Clip On Butane cylinders adapters
are available to fit the 4.5kg Butane hose. Valve sizes vary dependant
on gas supplier with 21mm standard for Calor 7kg & 15kg Butane.
Purchasers of
new caravans should be asked which gas they intend to use, or be
supplied with all hoses as standard. The Butane connection as well
as being for the UK market is also the standard connection for LPG
cylinders in France, so purchasers who intend to use their caravan
in France and in the UK on LPG or Propane would need to buy the
Propane and Butane Pigtails.
Continental
fittings?
The standard connection LPG in France is the M21.7 Butane Nut Connection.
We would recommend
that for Butane on the continent that Campingaz is used as the cylinders
are freely available, and can also be used in the UK. For Campingaz
the M20 x M20 hose connection is required plus the Campingaz adapter.
There should be no need to have a different pigtail for each country,
if Campingaz is used.
PUSH ON HOSES
ARE NO LONGER ALLOWED UNDER THE NEW REGULATIONS. ALL NEW HOSES MUST
HAVE A THREADED CONNECTOR.
All hoses supplied
by Nene Court Caravans will comply with BS3212 or BS EN 1763 and
have excess flow and non-return valves for safety. These are Calor
listed products.
These hoses will fit ALL regulators fitted to new vans, as the inlet
size is the same regardless of the manufacturer. All new 30mbar
regulators have a M20 inlet connection, and will be 450mm as specified
in the standard.
The new regulators fitted will have an over pressure connection
as required by EN1949.
Can the system
be retro fitted?
Most caravans built in the last 10 years will have appliances manufactured
to comply with the Gas Appliance Directive and these can cope with
an operating pressure of 30mbar. If in doubt check the appliance
data plate, instructions, or contact the manufacturer or local dealer.
It is not recommended
that the new EN12864 Annex D regulator be retrofitted to a caravan
or motor home manufactured before the introduction of EN1949 with
appliances which have an inlet pressure of 28mbar Butane or 37mbar
Propane
