LIMITED WARRANTY

COMFORT GLOW VENT-FREE NATURAL 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 the cost of part(s) required to
restore this heater to proper operating condition and an allowance for labor when provided by a DESA Authorized
Service Center. 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, INCI-
DENTAL 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.
