Safety and Installation Requirements

Please ensure that these instructions are read and understood before commencing installation. Failure to comply with

instructions listed below can cause product/property damage, severe personal injury, and/or loss of life. Ensure all

requirements are understood and fulfilled (including detailed information found in manual subsections).

Working on the equipment

The installation, adjustment, service

and maintenance of this product must

be done by a licensed professional

heating contractor who is qualified and

experienced in the installation, service

and maintenance of hot-water boilers.

There are no user-serviceable parts on

the boiler, burner or control.
