•
Installation of this boiler should be undertaken
only by trained and skilled personnel from
a qualified service agency. Follow these
instructions exactly.
•
Improper installation, adjustment, service, or
maintenance can cause property damage,
personal injury or death.
NOTICE: Due to the low water content of the
boiler, mis-sizing of the boiler with regard to the
heating system load will result in excessive boiler
cycling and accelerated component failure.
Thermal Solutions DOES NOT warrant failures
caused by mis-sized boiler applications. DO NOT
oversize the boiler to the system. Multiple boiler
installations greatly reduce the likelihood of boiler
oversizing.
