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 who 

will provide original factory replacement parts. Failure to use original factory replacement parts voids this warranty.

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. As with all concrete liners, this liner may develop slight cracks when exposed to heat. This 

cracking is considered normal. 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 PURCHASE PRICE OF THE PRODUCT AND DESA SHALL NOT BE LIABLE FOR ANY OTHER
