The following checks of safety systems must be made before putting the boiler into normal operation.
Before firing the boiler refer to Section 4 for information on the use of the controls, lighting, and shut-down
procedures.
NOTICE!
If the piping system attached to this unit will be chemically cleaned, the boiler must be disconnected
from the system and a bypass installed so that the chemical cleaning solution does not circulate through the boiler.
Following chemical cleaning, the system should be thoroughly rinsed to remove cleaning agents prior to
reconnecting the boiler to the system.
NOTICE!
Glycol and other additives must be approved for use in aluminum boilers and must meet the
requirements listed in Appendix B to prevent damaging the boiler.
NOTICE!
Under no circumstances should petroleum based cleaning or sealing compounds be used in the boiler
system.
NOTICE!
Chemicals added to the system must be approved by the chemical manufacturer for use in aluminum
boilers.
NOTICE!
Under no circumstances should the hydronic system be flushed while the boiler is attached to the
system since the debris or corrosion products could accumulate in the boiler and plug the boiler heat exchanger.
