• WATER TEMPERATURE SELECTION
To adjust the hot water temperature, turn the selector control to the right for hotter
water and to the left for cooler water.
• Whatever the water temperature selected, it remains constant even if there are
fluctuations in the mains water pressure, (within the minimum and maximum
range), due to the action of the automatic water flow regulator.
• Never reduce the flow of hot water by using the appliance’s water inlet
stopcock. This stopcock should always be fully open.
• TURNING OFF THE WATER HEATER
From whichever position the gas control knob is in, turn it to the right to the
●
position. This will cut off the supply of gas to the pilot and the burner.
• PRECAUTIONS TO BE TAKEN AGAINST FROST AND
FREEZING CONDITIONS
If the appliance is installed in caravan holiday home, leaving the appliance un-
drained during freezing conditions, will result in the appliance being frost
damaged. It must be drained down in the following way:
• Turn off the mains water inlet stopcock.
• Turn temperature control knob fully anticlockwise to minimum setting.
• Turn on all hot and cold water taps.
• Open all hot and cold drain cocks on the installation. Please refer to your
caravan owners handbook for the location of all drain cocks.
• Disconnect the mains water inlet stopcock from the caravan pipework, this will
stop water refilling the pipework, if the stopcock fails due to frost damage.
• Protect drain cocks and any open ended pipe from insects or debris.
To turn the water on again, close all drain cocks, reconnect and open the mains water
inlet stopcock and turn off each hot and cold water taps as the water runs clear.
We strongly recommend a qualified & competent service engineer is employed to
do the drain down service.
MAINTENANCE RECOMMENDATIONS
The appliance must be checked for safe operation annually, regardless of frequency
of use. This refers principally to the correct combustion of the main burner and pilot.
Maintenance should only be carried out by a qualified and competent service
engineer. Please refer to section 2.3 of this manual.
