LIMITED WARRANTY

COMFORT GLOW VENT-FREE RESIDENTIAL GAS HEATERS

DESA International warrants this product to be free from defects in materials and components for two (2) years from
the date of first purchase, provided that the product has been properly installed, operated and maintained in
accordance with all applicable instructions. To make a claim under this warranty the Bill of Sale or cancelled check
must be presented.

This warranty is extended only to the original retail purchaser. This warranty covers only the cost of part(s) required
to restore this heater to proper operating condition. Warranty part(s) MUST be obtained through authorized dealers
of this product and/or DESA International who will provide original factory replacement parts. Failure to use
original factory replacement parts voids this warranty. The heater MUST be installed by a qualified installer in
accordance with all local codes and instructions furnished with the unit.

This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts
that fail or become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by
improper installation. Travel, diagnostic cost, labor, transportation and any and all such other costs related to
repairing a defective heater will be the responsibility of the owner.

TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE
OF THE PRODUCT; THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED
WARRANTIES AND LIMITS THE DURATION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO TWO (2)
YEARS FROM THE DATE OF FIRST PURCHASE; AND DESA INTERNATIONAL’S LIABILITY IS
HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA INTERNATIONAL
SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT,
INCIDENTAL OR CONSEQUENTIAL DAMAGES.

Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental
or consequential damages, so the above limitation on implied warranties, or exclusion or limitation on damages may
not apply to you.

This warranty gives you specific legal rights, and you may also have other rights that vary from state to state.
