Do not use the boiler during construction.

 Construction dust and particulate, particularly drywall dust, will cause contamination 

of the burner, resulting in possible severe personal injury, death or substantial property damage.  Th e boiler can only be operated with 

a dust-free air supply. Follow the instruction manual procedures to duct air to the boiler air intake. If the boiler has been contaminated 

by operation with contaminated air, follow the instruction manual guidelines to clean, repair or replace the boiler if necessary.

 Affi  x these instructions near to the boiler. Instruct the building owner to retain the instructions for future use by a qualifi ed service 

technician, and to follow all guidelines in the User’s Information Manual.
