LABOR, SHIPPING, AND PROCESSING COSTS

For one (1) year after the Effective Date, Paloma will cover reasonable labor costs necessary to repair or replace a tankless 
water heater or component part it determines to be defective in material and/or manufacture by a contractor which is li-
censed, state qualifi ed, and trained for Paloma’s tankless water heater. Except for the above one (1) year labor, this Limited 
Warranty does 

not

 cover any 

labor expenses

 for service, repairs, reinstallation, permits, or removal and disposed of the 

failed water heater, or defective component part(s). All such expenses are your responsibility.
Paloma will pay the 

transportation costs

 for an “In-warranty” replacement water heater, or “In-warranty” replacement 

component part(s), to a convenient delivery point (selected by Paloma) near the place where the original water heater, 
or original component part(s), is located: such as a local Paloma water heater distributor. You must pay any local freight 
charges, including the cost of returning the failed water heater, or defective component part(s) to a convenient shipping 
location (selected by Paloma); such as a local Paloma distributor.
Paloma does 

not

 authorized, recommend, or receive any benefi t from any 

claims processing or similar fees

 charged by 

others to process warranty claims for any Paloma water heater or component part(s). Paloma will 

not

 reimburse any party 

for these, or any other, fees not specifi cally covered in this Limited Warranty document.

HOW TO OBTAIN WARRANTY CLAIM ASSISTANCE

Any claim for warranty assistance must be made promptly. First, determine if your water heater is “In-Warranty” (that is, 
within the Applicable Warranty Period). You can determine your unit’s warranty status by adding its Applicable Warranty 
Period to its date of purchase. However, if you do not have documentary proof of your water heater’s date of purchase, 
your unit’s warranty status will be based on its date of manufacture. The fi rst four digits of the unit’s serial number rep-
resent the month and year it was manufactured. Add the Applicable Warranty Period plus ninety (90) days to the date of 
manufacture to determine whether the water heater is still covered by this Limited Warranty. You may also determine your 
unit’s warranty status by obtaining the complete model number, complete serial number, and date of purchase of your water 
heater and then contacting Paloma at (805) 278-5480 during normal business hours (in the Pacifi c Time Zone) to determine 
if the Applicable Warranty Period has expired.
If your water heater is “In-warranty”, contact the plumber, or mechanical contractor, that installed it for assistance with the 
warranty repairs, or replacement, required. Paloma/Rheem Water Heaters’ 

Technical Service personnel are available to 

assist you (by telephone at (800) 432-8373 or via e-mail at [email protected])

 in obtaining “In-warranty” service 

or to answer your questions about the operation or repair of your water heater during normal business hours (in the Central 
Time Zone). Be prepared to provide the plumber, mechanical contractor, or Paloma/Rheem Technical Service person you 
call with the complete model number, the complete serial number, and the date of purchase of your water heater in addition 
to an explanation of your water heater problem.
If an exact replacement is not available, Paloma will provide you with the current model of your water heater, or compo-
nent part(s), or a replacement unit with comparable operating features. If government regulations or industry certifi cation 
or similar standards require the replacement water heater, or replacement component part(s), to have features not found in 
the defective water heater, or the defective component part(s), you will be charged for the difference in price represented 
by those required features. If you pay the price difference for these required features and/or to upgrade the size and/or other 
features available on a replacement new water heater, you will also receive a complete new Limited Warranty (with the full 
Applicable Warranty Periods) for the replacement new water heater.
