PRECAUTIONS AGAINST FREEZING DURING WINTER STORAGE
DURING COLD PERIODS AND IF THE WATER HEATER IS SITUATED IN A PLACE LIABLE TO FREEZE, THE
WATER MUST BE COMPLETELY DRAINED FROM THE WATER HEATER AS FOLLOWS:
1. TURN OFF THE COLD WATER SUPPLY.
2. OPEN ALL THE HOT WATER OUTLET TAPS ON THE INSTALLATION.
3. RELEASE THE DRAIN PLUGS FITTED AT THE LOWEST POINT OF THE PIPE WORK.
4. OPEN THE BLEED VALVE ON THE SIDE OF THE WATER INLET FITTING A FEW TURNS TO ALLOW AIR
INTO THE SYSTEM.
NOTE: THERE IS NO DRAIN PLUG FITTED TO THE HOT WATER HEATER SIDE OF THE WATER HEATER.
WHEN THE OPERATION IS FINISHED, CLOSE THE HOT WATER OUTLET TAPS AND REPLACE THE DRAIN
PLUG.
TO PUT THE WATER HEATER BACK INTO SERVICE, OPEN THE COLD WATER SUPPLY.
NOTE: IN A CARAVAN HOLIDAY HOME INSTALLATION THERE MAY BE A DRAIN COCK ON THE COLD
INLET UNDER THE HOME DIRECTLY BELOW THE WATER HEATER WHICH MAY BE USED.
THE WATER AND GAS PIPES MUST BE COPPER. DO NOT CONNECT PLASTIC PIPES DIRECTLY TO THE
HEATER. IT IS RECOMMENDED THAT THE COPPER IS EXTENDED TO BELOW THE FLOOR OF THE
CARAVAN/VEHICLE BEFORE CONNECTING TO PLASTIC.
THE WATER HEATER MUST BE INSTALLED WITH THE SUPPLIED FLUE KIT
MATERIALS AROUND THE FLUE SYSTEM – THE OUTER WILL REACH A MAXIMUM TEMPERATURE RISE OF
O
35
C. CARE SHOULD BE TAKEN IN ENSURING THAT ANY MATERIALS TOUCHING THE OUTER FLUE ARE
CAPABLE OF WITHSTANDING THIS TEMPERATURE FOR EXTENDED PERIODS. IT IS RECOMMENDED THAT
THE RUBBER INNER AND OUTER SEALS ARE PUSHED INTO THE WALL APERTURE BEFORE SEALING. THIS
WILL ENSURE THAT THE OUTER FLUE PIPE FITS CENTRALLY IN THE WALL APERTURE.
