c) Check the flexible hose frequently.d) The gas is heavier than air and thereforesinks to the lowest point.e) Keep bottle gas containers outside (andprotected against frost). If they must bekept inside make sure they are well awayfrom heat.VentilationAll ventilation complies with BSEN 721 andvents should not be obstructed in anymanner as this could lead to insufficientfresh air. In this case the confinedatmosphere becomes depleted of oxygenwhich leads to the formation of the highlypoisonous gas ‘carbon monoxide’. CarbonMonoxide is odourless, colourless andtasteless and will rapidly causeunconsciousness and death with little or nowarning prior to collapse. THERE IS NODANGER WHEN ADEQUATE VENTILATIONIS PROVIDED.Roof-mounted Flue installationsAll flue installations should be inspectedonce a year throughout their length forcorrosion. Flues should be replaced if anysign of perforation is found. Ensure that thereplacement is of an approved type.CONNECTIONEnsure that the gas regulator is correctlyconnected to the gas cylinder in gas bottlecompartment and that the hose is tight.Before turning on the gas supply, ensure thatall gas operated equipment in the caravan isturned off.All gas equipment is supplied through acentral Gas Manifold System which hasindividual isolation taps for each appliance,as follows:RED - Cascade Water HeaterWHITE - Space HeaterBLUE - FridgeGREEN - Hob & Oven (combination)GREEN - Hob (Separate)YELLOW - Oven (Separate)YELLOW - Barbecue (if fitted)Thermal insulation heatingYour caravan has been designed to achievea thermal insulation and heating level forspecific climatic conditions. Theclassifications are as follows:GRADE 1A caravan with an average thermaltransmittance (u) that does not exceed1.7w/(m 2 k).GRADE 2A caravan with an average thermaltransmittance (u) that does not exceed1.7w/(m 2 k) and which can achieve anaverage temperature difference of at least20k between inside and outside temperatureswhen the outside temperature is 0°C.ServicesGRADE 3A caravan with an average thermaltransmittance (u) that does not exceed1.2w/(m 2 k) and which can achievean average temperature difference of atleast 35k between inside and outsidetemperatures when the outside temperatureis -15°C.29
