Alpha Evoke 28 and 33
The boiler has a built in frost protection function to protect the boiler (only) from freezing.
If water within the boiler
falls belo
w 4°C the boiler will fire in heating mode and raise the temper
ature of the heating water (in the boiler only)
to 30°C.
For this function to be activ
e the gas and electricity supplies to the boiler m
ust be turned on and the boiler be in either
'Standby' or 'On' mode
.
Further protection f
or the mains water supply and heating circuit m
ust be provided separ
ately.
If Alpha exter
nal controls are fitted, a frost protection setting is incorpor
ated into the room thermostat activ
ating the central
heating when the temperature f
alls below 5°C
.

CONDENSATE DRAINA
GE
High efficiency (condensing) boilers remo
ve more useful heat from the comb
ustion gases, resulting in
additional water
vapour
which is
collected within
the boiler (as condensate)
and run
to a suitab
le dr
ainage point
via the
condensate
drainage pipe
.
Where possible the condensate dr
ain should be connected internally to a w
aste pipe within the property to pre
vent
the risk of freezing.
If the condensate drain pipe r
uns 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 e
xtremes of temperature or wind-chill the use of a propr
ietary tr
ace-heating system
for e
xternal condensate dr
ainage pipew
ork, incor
porating an e
xternal frost ther
mostat, should be considered.
