LIMITED WARRANTY

VANGUARD VENT-FREE RESIDENTIAL GAS HEATERS

DESA International warrants this product and any parts thereof, to be free from defects in material and
workmanship for two 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 sales or proof of purchase must be presented.

This warranty is extended only to the original retail purchaser. This warranty covers only the cost of parts and
labor required to restore this heater to proper operating condition. Warranty parts 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, alteration,
tampering, contaminated fuels, or defects caused by improper installation. Travel, transportation, and incidental
costs associated with warranty repairs are not reimbursable under this warranty and are 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 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 of how long an implied warranty lasts or an exclusion or limitation of
incidental or consequential damages, so the above limitation of implied warranties, or exclusion, or limitation
of damages may not apply to you.

This warranty provides the original retail purchaser with specific legal rights. For specific information regard-
ing those rights, please consult the applicable state laws.
