FLOW
•
This unit comes equipped with hea
ting
blocks to protect it against damages associated with freezing.
•
For this freeze prot
ection
system to operate, there has to be electrical power to the unit. Damage
to the heat exchanger caused by freezing temperatures due to power loss is not covered under the
warranty. In cases where power losses can occur, consider the use of a backup power supply.
•
The freeze protec
tion
system will ac
ti
vate when the surrounding and/or outside temperatures drop
•
It is the installer’s responsibility to be aware of freezing issues and take all preventa
ti
ve measures. The
manufacturer will not be responsible for any damage to the heat exchanger as a result of freezing.
•
If you will not be using your boiler for a long period of
time:
1.
Completely drain the water out of the unit. Refer to p. 44.
2.
Disconnect power to your boiler.
This will keep your unit from freezing and being damaged.

The
fl
ow rate through the micro-boiler is limited to a maximum of 10.0 GPM (38 L/min).
•
The temperature se
ttin
g, along with the suppl
y temperature of the water will determine the flow
rate output of the unit.
Only pipes within the micro-boiler are protected by the freeze prot
ection
system.
Any water pipes (hot or cold) located outside the unit will not be protected.
Properly protect and insulate these pipes from freezing.

In any area subject to freezing temperatures, freezing issues can occur if cold air enters through the
venting into the heat exchanger by either negative pressures within the installation location or by
strong outside wind. The manufacturer highly recommends the use of a backflow preventer (sold
separately) to minimize the amount of cold air entering through the exhaust venting when the micro-
boiler is off.
