Installation Instructions

37
FLOW
• The ow rate through the micro boiler is limited to a maximum of 10.0 GPM (38 L/min).
• The temperature setting, along with the supply temperature of the water will determine the ow
rate output of the unit.
FREEZE PROTECTION SYSTEM
• This unit comes equipped with heating blocks to protect it against damages associated with freez-
ing.
• For this freeze protection system to operate, there has to be electrical power to the unit. Damage
to the heat exchanger caused by freezing temperates due to a power loss is not covered under
warranty. In cases where power losses can occur, consider the use of a backup power supply.
• The freeze protection system will activate when the surrounding and/or outside temperature drop.
• It is the installer’s responsibility to be aware of freezing issues and take all preventive measures.
The manufacture will not be responsible for any damage to the heat exchanger as a result of
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 back ow preventer
(sold separately) to minimize the amount of cold air entering through the exhaust venting when the
micro boiler is off.
• It is the installer’s responsibility to be aware of freezing issues and take all preventive measures.
The manufacture 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.
2. Disconnect power to your boiler.
This will keep your unit from freezing and being damaged.
Only pipes within the micro boiler are protected by the freeze protection system.
Any water pipes (hot or cold) located outside the unit will no be protected. Properly
protect and insulate these pipes from freezing.
