Chapter 3 CARAVAN SERVICE SYSTEMS
All gas appliances in your tourer can have their gas supply individually
isolated by turning off the relevant tap. The tap is either located on the
centrally positioned gas manifold or directly beside the appliance.
Regularly check flexible gas hose, joints and connections for tightness.
Finally make sure that each gas appliance is working efficiently to the
recommendations of the appliance manufacturers.
The regulator is a governing device which adapts the bottle pressure to
one that suits the equipment in the caravan.
Caution: Regulator valves should always be in the ‘OFF’ position when towing.
Warning: Some industrial LPG appliances operate at high pressure
and require a ‘high pressure’ regulator. This often has an adjusting
handle on it. Never use such a regulator on a caravan.
Propane and Butane gas regulators are not interchangeable.
Hoses: Hoses should be made from Neoprene, and should conform to
BS 3212. Rubber hosing should never be used. It is good practice to
replace hoses annually with the approved type and in any case not later
than the expiration date marked on the hose. A jubilee clip is a worthwhile
addition to prevent accidental removal of the hose.
The hose should not be longer than 700mm.
Changing Gas Cylinders
Ensure that the cylinder is empty, then
i. turn off cylinder valve and all gas appliances
ii. release retaining strap
iii. remove cylinder from gas locker and stand on
ground. Avoid tension on rubber gas hose.
