This manual is intended only for use by a qualified heating installer/technician. Read and follow this manual, all supplements and related

instructional information provided with the boiler. Install, start and service the boiler only in the sequence and methods given in these

instructions. Failure to do so can result in severe personal injury, death or substantial property damage.

Do not use the boiler/water heater 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. The 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.

Affix these instructions near to the boiler/water heater. Instruct the building owner to retain the instructions for future use by a qualified

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