Installation and Operation Instructions
FOR YOUR SAFETY: This product must be installed and serviced by a professional service technician,
qualified in hot water boiler and heater installation and maintenance. Improper installation and/or operation
could create carbon monoxide gas in flue gases which could cause serious injury, property damage, or
death. Improper installation and/or operation will void the warranty.
If the information in these instructions is
not followed exactly, a fire or explosion
may result causing property damage,
personal injury or death.
Do not store or use gasoline or other
