MODINE MANUFACTURING COMPANY
LIMITED WARRANTY
(Residential Use Only)
WHAT THIS WARRANTY COVERS
This warranty covers all defects in material and workmanship in your
Modine unit heater, when used for your home or garage.
WHAT THIS WARRANTY DOES NOT COVER
Unit heater, or any of its parts:
1. which have been improperly installed or removed.
2. which have been damaged other than by normal use.
3. which have not been properly maintained.
4. which have been exposed to gas input more than 5% higher than
specified on the serial plate of the unit heater, resulting in over-firing of
the heater.
5. which have been exposed to possibly corrosive chemicals or chemical
vapors (such as found in swimming pools), or potentially explosive or
flammable atmospheres laden with grain dust, sawdust, or similar air-
borne materials.
6. where any defect has been caused by abuse, misuse, neglect,
carelessness, or accident.
7. where the serial number of the unit heater has been altered, defaced,
or removed.
8. which are used in a confined space without adequate combustion air,
such as can be found in more air-tight construction.
WHO THIS WARRANTY COVERS
This warranty covers the purchaser of the unit heater or anyone else who
owns it during the warranty period.
HOW LONG THE WARRANTY LASTS
1. The warranty for the heat exchanger of the unit heater remains in force
for ten years from the date you purchased the unit heater.
2. The warranty on all other parts of the heater remains in force for two
years from the date you purchased the unit heater.
WHAT MODINE WILL DO TO CORRECT ANY WARRANTY DEFECTS,
AND HOW YOU CAN GET WARRANTY SERVICE
In the event of warranty failure, Modine will provide replacement parts
at Modine's cost. To obtain warranty repairs or replacement of defective
parts, you must, within the period of warranty coverage, contact the agency
from whom you purchased the unit heater. That seller, or the service
agency performing service for the seller, will determine whether or not
the unit heater, or any of its parts, is in fact defective, and will then either
repair or obtain and install the necessary replacement parts for you. If it
is determined that the unit heater or parts were not defective, you may be
charged for any replacement parts.
CAUTION - Do not attempt to repair the unit heater yourself, nor remove it
or any of its parts. This must be done by a qualified service agency.
If you have any questions about this warranty, call the person from
whom you purchased the unit heater; or a Modine Heating Products
Representative at 1-800-828-4328.
WHAT MODINE WILL NOT DO
Modine will not reimburse you for any labor costs or service charges
related to warranty repairs or replacements.
INCIDENTAL AND CONSEQUENTIAL DAMAGES DISCLAIMED
This warranty does not cover incidental damages, such as use of substitute
heating equipment, or other costs arising from the loss of use of the unit
heater. This warranty also does not cover consequential damages, such as
the cost of repairing or replacing other property which is damaged when
this unit heater does not work properly.
HOW STATE LAW RELATES TO THIS WARRANTY
Some states do not allow the exclusion or limitation of incidental or
consequential damages so the above limitations or exclusions may not
apply to you.
This warranty gives you specific legal rights, and you may also have other
rights which vary from state to state.
