DANGER
DO NOT store or use gasoline or other flammable vapors or liquids in the vicinity of this or any other
appliance.
WARNING
Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal
injury or loss of life. Failure to follow all instructions in the proper order can cause personal injury or
death. Read and understand all instructions, including all those contained in component manufacturers
manuals which are provided with the appliance before installing, starting-up, operating, maintaining or
servicing this appliance. Keep this manual and literature in legible condition and posted near appliance
for reference by owner and service technician.
This boiler requires regular maintenance and service to operate safely. Follow the instructions contained
in this manual.
Installation, maintenance, and service must be performed only by an experienced, skilled and knowledgeable
installer or service agency.
All heating systems should be designed by competent contractors and only persons knowledgeable in
the layout and installation of hydronic heating systems should attempt installation of any boiler.
It is the responsibility of the installing contractor to see that all controls are correctly installed and are
operating properly when the installation is completed.
Installation is not complete unless a pressure relief valve is installed into the specified tapping on the
supply manifold located on top and at rear of appliance - See Section III, Paragraph R, Item of this
manual for details.
All boiler builds, except boilers bearing the UL Label, are suitable for installation on combustible flooring.
Do not install boiler on carpeting. Do not operate on floors where heat affected material is below.
Do not tamper with or alter the boiler or controls. Retain your contractor or a competent serviceman to
assure that the unit is properly adjusted and maintained.
Clean boiler at least once a year - preferably at the start of the heating season to remove soot and scale.
The inside of the combustion chamber should also be cleaned and inspected at the same time.
Have Burner and Controls checked at least once a year or as may be necessitated. Do not operate
unit with jumpered or absent controls or safety devices. Do not operate unit if any control, switch,
component, or device has been subject to water.
This boiler is designed to operate with lower return water temperatures and avoid thermal shock and
accumulation of condensate if operated per the following criteria:
• Minimum Return Water Temperature = 80°F
• Maximum Delta T Between Boiler Supply and Return = 80°F
• Minimum Supply Water Temperature = 10°F
Continued operation beyond these limitations will result in sustained condensing within the combus-
tion chamber and potentially reduce boiler longevity and may result in premature boiler failure through
thermal shock.
