Takagi units must be installed by licensed professionals; installation done by anyone other than 
licensed professionals will result in the

days of original purchasing date by retailed buyer.  Proof of copy of original purchasing date must be sent

defective component parts and shipping.  Takagi is not liable for any special, incidental, or indirect 
consequential damages including property or personal damages, loss of use, failure to install drain pan

Parts Warranty: 
If a mechanical and/or electrical part except the heat-exchanger fails within five (5) years in normal 
residential operation or within three (3) years

domestic), and/or a multi-family residential dwelling applications with proper installation (see instruction 
from installation manual) from the purchasing date, Takagi Industrial Co. USA, Inc. will furnish a 
replacement part(s) excluding field labor and shipping.

If the heat-exchanger fails within ten (10) years in normal residential operation with proper installation 
(see instruction from installation manual) from the installation date, Takagi Industrial Co. USA, Inc. will

have its own dedicated return line.
