including, but not limited to, damage from any of the following:

operation with insufficient water, allowing the boiler to freeze,

PROCEDURE FOR OBTAINING WARRANTY SERVICE

In order to assure prompt warranty service, the owner is

requested to complete and mail the attached Warranty Card within

ten days after the installation of the boiler, although failure to comply

with this request will not void the owner’s rights under these

warranties.

Upon discovery of a condition believed to be related to a defect in

material or workmanship covered by these warranties, the owner

should notify the installer, who will in turn notify the distributor.  If

this action is not possible or does not produce a prompt response,

the owner should write to U.S. Boiler Co., Inc., Burnham Hydronics,

at P.O. Box 3079, Lancaster, PA  17604, giving full particulars in

support of the claim.

The owner is required to make available for inspection by U.S.

Boiler Co., Inc. or its representative the parts claimed to be

defective and, if requested by U.S. Boiler Co., Inc. to ship these

parts prepaid to U.S. Boiler Co., Inc. at the above address for

inspection or repair.  In addition, the owner agrees to make all

reasonable efforts to settle any disagreement arising in connection

with a claim before resorting to legal remedies in the courts.

THIS WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS AND

YOU MAY ALSO HAVE OTHER RIGHTS WHICH VARY FROM

STATE TO STATE.

Subject to the terms and conditions set forth below, U.S. Boiler™

Co., Inc. Lancaster, Pennsylvania hereby extends the following limited

warranties  to  the  original  owner  of  a  residential  grade  water  boiler

U.S. Boiler Co., Inc. warrants to the original owner that its residential

grade water boilers comply at the time of manufacture with recognized

hydronic industry standards and requirements then in effect and will be

free of defects in material and workmanship under normal usage for a

period of one year from the date of original installation.  If any part of

a water boiler is found to be defective in material or workmanship during

this one year period, U.S. Boiler Co., Inc. will, at its option, repair or

replace the defective part.

LIFETIME LIMITED WARRANTY

ON HEAT EXCHANGER

U.S.  Boiler  Co.,  Inc.  warrants  to  the  original  owner  that  the  heat

exchanger of its residential grade water boilers will remain free from

defects  in  material  and  workmanship  under  normal  usage  for  the

lifetime of the original owner at the original place of installation.  If a

claim is made under this warranty during the first ten years from the

date of original installation, U.S. Boiler Co., Inc. will, at its option, repair

or replace the heat exchanger.  If a claim is made under this warranty

after the expiration of ten years from the date of original installation,

U.S. Boiler Co., Inc. will, at its option and upon payment of the pro-rated

service charge set forth below, repair or replace the heat exchanger.

The service charge applicable to a heat exchanger warranty claim is

based  upon  the  number  of  years  the  heat  exchanger  has  been  in

service and will be determined as a percentage of the retail price of the

heat exchanger model involved at the time the warranty claim is made
