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 safety (relief) valve is installed into the specied tapping on the supply manifold
located on top and at rear of appliance.
This boiler is NOT suitable for installation on combustible ooring.
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.
Carbon monoxide is an odorless, deadly gas that may be introduced into your building by any malfunctioning
fuel burning product or vent system failure. It is recommended that a carbon monoxide detector be installed and
interlocked to the appliance limit string. Consult your local jurisdiction for additional requirements.
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.
Return water cannot be lower than 135°F for prolonged periods of time. Operation under these conditions will result
in sustained condensing within the combustion chamber and potentially reduce boiler longevity.
In addition, the return water cannot be introduced into the boiler if it is more than 40°F less than the idle boiler tem-
perature. Continued operation under these conditions may result in premature boiler failure through thermal shock.
Example: A boiler that has been idle for some time since the last heat demand cycle may have it’s boiler water
temperature reduced to 150°F. The return temperature from the next zone activation cannot be less than 110°F.
DO NOT store or use gasoline or other ammable vapors or liquids in the vicinity of this or any other appliance.
If you smell gas or fuel oil vapors, do not try to operate the burner/boiler system. Do not touch any electrical switch
or use any phone in the building. Immediately call the gas or oil supplier from a remotely located phone.
Burner/boiler systems produce steam or hot water in a pressurized vessel by mixing extremely ammable gaseous,
liquid or solid fuels with air to produce combustion and very hot products of combustion. Explosions, res severe
personal injury, death and/or property damage will result from improper, careless or inadequate installation, operation
or maintenance of fuel-burning and boiler equipment.
NE PAS entreposer ni utiliser d’essence ou d’autres vapeurs ou liquides inammables à proximité de cet appareil
ou de tout autre appareil.
Si vous sentez des vapeurs de gaz ou de mazout, n’essayez pas de faire fonctionner le système brûleur / chaudière.
Ne touchez à aucun interrupteur électrique et n’utilisez aucun téléphone dans le bâtiment. Appelez immédiatement
le fournisseur de gaz ou de pétrole à partir d’un téléphone situé à distance.
Les systèmes de brûleurs / chaudières produisent de la vapeur ou de l’eau chaude dans un récipient sous pression
en mélangeant des combustibles gazeux, liquides ou solides extrêmement inammables avec de l’air pour produire
une combustion et des produits de combustion très chauds. Les explosions, les incendies, des blessures graves, la
mort et / ou des dommages matériels résulteront d’une installation, d’une utilisation ou d’un entretien inappropriés,
imprudents ou inadéquats des équipements de chauage et de chaudière.
