The boiler has a built in frost protection function to protect the boiler (only) from freezing. If water within the boiler falls below
4°C the boiler will fire in heating mode and raise the temperature of the heating water (in the boiler only) to 30°C.
For this function to be active the gas and electricity supplies to the boiler must be turned on and the boiler be in either
'Standby' or 'On' mode.
Further protection for the mains water supply and heating circuit must be provided separately.
If Alpha external controls are fitted, a frost protection setting is incorporated into the room thermostat activating the central
heating when the temperature falls below 5°C.
High efficiency (condensing) boilers remove more useful heat from the combustion gases, resulting in additional water vapour
which is collected within the boiler (as condensate) and run to a suitable drainage point via the condensate drainage pipe.
If the condensate drain pipe runs outside it should be fitted with increased diameter pipe and be suitably lagged to reduce
the risk from freezing.
In situations where there are likely to be extremes of temperature or wind-chill the use of a proprietary trace-heating system
for external condensate drainage pipework, incorporating an external frost thermostat, should be considered.
8 OPTIONAL BOILER CONTROLS (if fitted)
There is a range of controls available from Alpha to operate your boiler. In addition to the items listed below the Alpha InTec
boilers are compatible with most controls available on the market. However to get the most comfort and efficiency from your
boiler we recommend the Alpha Climatic controls with enhanced remote boiler functions and efficiency control.
Please refer to the instructions provided with the controls for further information on their setting and use.
