TERMS AND CONDITIONS OF WARRANTY
Viessmann provides this Warranty only to the original end user
purchaser (the "Owner") of a Viessmann Stainless Steel Hydronic
Heating Boiler of less than 530,000 BTU output purchased after
September 1, 2016, in the United States of America for installations
in the United States (the "Boiler"), provided the Owner uses the Boiler
at the site of original installation in accordance with the terms hereof.
This Warranty provides specific legal rights. You may have other
rights which vary from State to State in the United States of
America. The rights in this Warranty are conditioned upon: (a) the
proper installation of the Boiler in accordance with all applicable
rules, regulations, industry standards and Viessmann instructions
by a mechanical contractor or installer whose principal occupation is
the sale and installation of heating, plumbing, and/or air conditioning
equipment and who is properly licensed under all relevant and/or
applicable laws of the jurisdiction in which the Boiler is installed
("Contractor"); (b) proper operation, and maintenance of the Boiler
by a Contractor in accordance with the product manuals; (c) the
original and continuous installation and use of the Boiler by an
Owner within the United States of America; and (d) performance of
warranted part replacements or repairs by a Contractor.
WARRANTY AND WARRANTY PERIODS
Viessmann's obligation under this Warranty is limited to the repair
or replacement, at the sole discretion of Viessmann, of any goods
or parts which do not conform to the express Warranty provided
herein. Labor and all other costs for the examination, removal
and/or re-installation of defective parts, and transportation costs
for defective or replacement parts, are not covered by this Warranty.
LIMITED TWO (2) YEAR WARRANTY
Viessmann warrants that the Boiler enclosure, burner, controls, and
other accessories Viessmann provides as standard equipment on
the Boiler will be free from defects in material and workmanship for
TWO (2) YEARS from the Date of Original Installation of the Boiler.

LIMITED LIFETIME WARRANTY FOR THE PRESSURE VESSEL
AFTER THE TENTH (10TH) YEAR FOR RESIDENTIAL APPLICATIONS
If the Owner uses the Boiler exclusively in a Residential
Application, Viessmann warrants that the pressure vessel
will remain free from defects in materials and workmanship
resulting
in
a
leak
Repair or replacement of a pressure vessel defective in material or
workmanship after the tenth year in Residential Applications will
be made only upon the Owner's payment of a proportionate charge
based upon the length of time the pressure vessel has been installed.
The proportionate charge is the percentage of the then current
Viessmann list price of the pressure vessel when the warranty
claim is made, determined as follows: 11th year - Owner 20%,
Viessmann 80%; 12th year - Owner 40%, Viessmann 60%;
13th year - Owner 50%, Viessmann 50%; 14th year - Owner 60%,
Viessmann 40%; 15th year and beyond - Owner 75%, Viessmann 25%.
If a pressure vessel for the Boiler is no longer available when the
warranty claim is made, Viessmann will provide a new condensing
Boiler at the then current retail price subject to the following: The
Owner must pay the then current retail price for the replacement
boiler less a credit based upon (1) the percentage the list price
of the pressure vessel of the new boiler bears to the list price of
the entire boiler, and (2) Viessmann's share of the proportionate
charge detailed above. By way of example, if the pressure vessel
fails in the 14th year and the list price of the pressure vessel is
30% of the list price of the new boiler, the Owner will receive a
credit of 12% of the retail list price of the new boiler (30% of
Viessmann's 40% share of proportionate charge in the 14th year).
REPLACEMENT PARTS
Replacement or repaired parts provided under this Warranty are
warranted for the applicable unexpired period of this Warranty,
or the term of Viessmann's Parts Warranty, whichever is longer.
COMMENCEMENT OF WARRANTY PERIODS

(the "Date of Original Installation"). In the event of a dispute
as to the Date of Original Installation, the shipping date from
the
the Viessmann facility, as recorded in the books and records of
Viessmann, shall be deemed to be the Date of Original Installation.
