Anti-freeze function
The gas boiler has anti-freeze function.
If the gas and power is on, the boiler will start
to work automatically when the heating water
temperature is below 5
°C
, and heat the water
in the system to about 30
°C
.
Warning!
The anti-freeze function may not ensure water
will circle the whole heating system.
If the gas boiler stop running for several
hours in very cold weather, it may lead to the
system becoming frozen. If you are not at
home during freezing period, be sure to keep
the heating function running, and keep the
temperature of every room above the freezing
point.
However, when there is some external failure,
such as gas or, power outage or air exhaust
system are abnormal, the inner inspection
device will turn off the boiler automatically,
so it can’t protect against freezing. To avoid
such situation, if there are no people at home
for long periods, you may ask the installer/
engineer to drain out the water in heating
system and gas boiler.
Warning!
When the gas boiler is executing the anti-
freeze function, it may need to conduct
combustion work. So the gas supply must be
sure smooth and water in the heating system.
