Hosing and Piping:
Check flexible hoses for cracking and condition. Check
the date stamped on them has not passed. If the expiry date is close or
passed, have the hoses replaced. Check all rigid piping for adequate
support and any damage.
Appliances:
As a guide checking the gas appliances can be summarised
as follows:
• Cleaning: where appropriate, remove cover(s) to gain access to exchanger.
Remove any build up of fluff or other foreign matter. Re-assemble and
test operation. Clean flame-viewing window.
Operation of controls: Check all knobs etc are secure on their spindles and
that they work smoothly. Check that the appliance works properly by using
normal controls without forcing. If the gas taps are stiff to operate, ease
them open with an approved LPG grease.
Flame Structure:
• Pilot flames should burn quietly and cleanly.
• Refrigerator: When the fridge gas control is turned to maximum the flame
colour should be predominantly blue.
• Water heater: The main burner should burn blue and of even height.
• Ovens: Flames should be of even height and burn quietly. The colour
should be mainly blue/green but there will be yellow tips to the flames as
the burner heats up.
• Grill burners: Flames may develop yellow tips as they heat up, especially
when using butane.
• General comments: A flame lifting away from the burner indicates that the
pressure is too high. A yellow flame causes sooting and indicates the
pressure is too low. If these faults occur, recheck the regulator, cylinders
and pipes, adjust as necessary.
• Flues: Check security of fixings, attachments to appliances and flue
terminals. Check for damage and corrosion. Check for gas leakage
into the vehicle.
• Flame failure device (FFD): Check for satisfactory operation by the
following method: after the appliance has been checked, allow time for
the thermocouple to cool. Try to relight the appliance by turning it on
without pushing the gas control knob in. If the appliance does not light
the FFD is working.
• Security: Check that all appliances are securely fixed to the vehicle/
furniture and that no ‘play’ is present. Where applicable check that the
water pipes are properly attached and there are no signs of leaks.
9. Water System
Before operating the water system, check the following items visually for
signs of leakage.
Fresh Water Tank/Container:
Check condition. Fill tank and check for
leaks. Check external filler and filler pipe to tank. Check venting. Check
presence and condition of filler cap.
Waste Water Tank:
Check that the drain tap is clear and working properly.
Make sure that the drain hose is present and in good condition.
