BOTTLED GAS SYSTEM
WARNING!
Fire risk.
If any gas appliance is lit, driving into a
petrol station is prohibited.
Schematic of the bottled gas system.
BOTTLED GAS
Bottled gas is a petroleum product. When bottled gas
burns, it gives off carbon dioxide and steam. A good
supply of air is essential to ensure complete combustion.
A gas hob with two burners requires up to 7 times as
much air as a person undertaking heavy physical labour.
Bottled gas is heavier than, and mixes readily with,
surrounding air. However, under certain circumstances, it
will collect in low-lying spaces.
Bottled gas has a characteristic odour.
Bottled gas is not toxic (no known toxicity symptoms).
There are two sorts of bottled gas (i.e. liquefied
petroleum gas – LPG):
• Propane (C

H

)
• Butane (C

H

)
Propane gasifies at temperatures down to around -40°C.
Butane gasifies at temperatures down to around ±0°C.
Ask for propane if you will be using gas in the winter.
Propane is sold in Red bottles in the UK, Butane in Blue
or Green bottles.
In other countries, bottles may be of a different colour.
THE BOTTLED GAS SYSTEM
The gas bottle is stored in the bottle locker.
The gas bottle locker is an enclosed, ventilated space
that is separated from the living area. The locker has
ventilation holes in the floor. These allow any leaking
gas to escape.
The bottled gas system uses copper pipes with screw
fittings . The gas bottle is connected to the gas system
via an approved rubber hose.
The system has a number of valves allowing partial or
total closure of the system.
The system’s master valve is on the gas bottle.
In its standard version, the motorhome has three gas
appliances.
• hob,
• boiler,
• refrigerator.
WARNING!
Fire risk.
Bottled gas is classified as a highly
flammable gas. It must be treated with
respect.
If there is any suspicion of a leak, close
the gas bottle’s master valve and have a
professional test the gas system for leaks.
Valves are used to close off parts of the bottled
gas system.
