PRECAUTIONS AGAINST FREEZING DURING WINTER STORAGE
If the holiday home is to be un-occupied during cold periods, and whenever there is a threat of freezing, the
domestic hot and cold water circuit must be drained as follows:
-Turn off the cold water supply.
-Open all hot and cold taps.
-Open all drain plugs in the hot and cold water system (Do not drain the central heating circuit which should
have been filled with antifreeze) If the boiler is installed in a Caravan Holiday Home, refer to the user
manual for the home, for the positions of all drain plugs.
Note: There are no drain plugs fitted to the actual boiler.
-Leave all taps and plugs open until the boiler is next needed for service. This will allow any residual water to
continue to drain.
NOTES ON FROST PROTECTION
The boiler inbuilt frost protection feature is designed primarily to prevent damage to the heating cir-
cuit and radiators. It will not protect the hot and cold water pipes from freezing under the holiday
home and will provide only a limited protection to the boiler pipework and hot and cold pipework
inside the holiday home.
The heating circuit and radiators should contain the correct level of antifreeze to prevent damage
during freezing conditions and should not be drained down.
For the frost feature to work, the gas supply must be left on and the electrical power supply (wall
socket), must be connected and switched on, the central heating control knob on the boiler must be
in the off position.
Do not rely on the boiler frost protection to prevent freezing of the hot and cold water pipes,
including those inside the boiler during severe frost conditions, it will not.
ALL FROST DAMAGE IS OUTSIDE OF THE WARRANTY
