Limited Warranty

UPG warrants this product to be free from defects in factory workmanship and material under normal use and service and will, at its option, repair or replace
any parts that prove to have such defects according to the terms outlined on the reverse side of this warranty. This warranty covers only the equipment
described by the Product Model Number and Serial Number listed on the Warranty Registration Card.
UPG warrants the primary heat exchangers in the product to be free from defects in factory workmanship and material under normal use and service and will at
its option, repair or furnish a replacement heat exchanger, either new or reconditioned, that meets the intended fit, use and function of the original heat
exchanger for any heat exchanger furnished by UPG which proves to have such defects within the duration of warranty coverage. Alternatively, UPG may, at its
option, extend a replacement allowance to be applied toward the purchase of a new furnace or packaged unit marketed by UPG. The exact amount of the
allowance will be determined at the discretion of UPG, based upon current market conditions, but in no case shall this allowance exceed thirty (30) percent of
the original consumer purchase price of the furnace, excluding such items as ductwork, wiring, piping and installation costs. UPG shall have no responsibility
hereunder for installation, shipping, handling or other charges except as specifically provided herein.
For your benefit and protection, return the Warranty Registration Card to UPG promptly after installation. This will initiate the warranty period and allow us to
contact you, should it become necessary. In the absence of a recorded Warranty Registration Card, the warranty period will begin upon product shipment from
UPG.
This warranty extends only to the original consumer purchaser and is non-transferable. For this warranty to apply, the product must be installed according to
UPG recommendations and specifications, and in accordance with all local, state, and national codes; and the product must not be removed from its place of
original installation. The warranty period for repair or replacement parts provided hereunder shall not extend beyond the warranty period stated on the reverse
side of this warranty.

UPG strongly recommends regular periodic preventative maintenance on this equipment. The person most familiar with the equipment in your HVAC system is
a UPG dealer. The UPG dealer can ensure your maintenance program meets the conditions of the "UPG Warranty", maximize the efficiency of the equipment,
and service your unit within the mandated guidelines with regard to unlawful discharge of refrigerants into the atmosphere.
This warranty applies only to products installed in the United States and Canada.
