1.  If within TEN years after initial installation of the boiler, a heat exchanger or gas burner should prove upon examination by the warrantor to be defective in 

material or workmanship, the warrantor, at his option will exchange or repair such part or portion.  This term is reduced to FIVE years if this boiler is used for 

water heating purposes other than hydronic space heating.

 

a.  This warranty is extended to the owner for all other parts or portion during the FIRST year following initial installation of this boiler.

 

b.  The warranty on the repair or replacement of the part or portion will be limited to the unexpired term of the original warranty.

2.

  CONDITIONS AND EXCEPTIONS

 

This warranty should apply only when the boiler is installed in accordance with local plumbing and building codes, ordinances and regulations, the printed 

instructions provided with it and good industry practices.  In addition, a pressure relief valve, certified by C.S.A. and approved by the American Society of 

Mechanical Engineers, must have been installed and fresh water used for filling and make-up purposes.

 

a.  This warranty should apply only when the boiler is used:

 

  (1)  with  inlet  water  temperature  120°F  (49°C)  and  above  and  outlet  water  temperatures  not  exceeding  the  maximum  setting  of  its  operative  and/ 

 

   

or high limit control;

 

  (2)  at water pressure not exceeding the working pressure shown on the boiler;

 

  (3)  when filled with boiler water, free to circulate at all times and with the heat exchanger free of damaging scale deposits;

 

  (4)  in a non-corrosive and non-contaminated atmosphere;

 

  (5)  in the United States, its territories or possessions, and Canada;

 

  (6)  at a water velocity flow rate not exceeding or below the boiler’s designed rates;

 

  (7)  indoor installation only.

 

b.  Any accident to the boiler, any misuse, abuse (including freezing) or alteration of it, any operation of it in a modified form, or any attempt to repair leaks in 

the heat exchanger will void this warranty.

3.

  SERVICE AND REPAIR EXPENSE

 

Under this limited warranty the warrantor will provide only a replacement part.  The owner is responsible for all other costs.  Such costs may include but are 

not limited to:

 

a.  Labor charges for service, removal, repair, or reinstallation of the component part;

 

b.  Shipping, delivery, handling, and administrative charges for forwarding the replacement part from the nearest distributor and returning the claimed defective 

part to such distributor.

 

c.  All cost necessary or incidental for any material and/or permits required for installation of the replacement.

4.

  LIMITATIONS ON IMPLIED WARRANTIES

 

Implied warranties, including any warranty of merchantability imposed on the sale of this boiler under state or provincial law are limited to one (1) year duration 

for the boiler or any of its parts.  Some states and provinces do not allow limitations on how long an implied warranty lasts, so the above limitation may not 

apply to you.

 

5.
