GAS REGULATORS
Caravans made before 2004 were supplied without a gas regulator. Two types are available, one suitable for butane LPG, the other for propane LPG. The butane regulator is set for a gas pressure of 28m bar, while the propane one operates at 37m bar. The regulators are also been designed so that they are not interchangeable. However, all the gas appliances in the caravan are suitable for use with both butane and propane without alteration.
From '04 on, butane and propane supplied throughout the European Community will be at a pressure of 30m bar. As a result, all vans will be supplied with a 30m bar regulator as standard, which can take either gas. However, the two gases do require different types of flexible connecting hoses, so it's up to buyers to choose which type of gas and hose to use, or to keep both types of hose on board. Regardless of the type of regulator it must be checked regularly by a competent gas technician, since if it fails, it could allow gas at too high a pressure to enter the system.
