This FINLANDIA SAUNA heater is guaranteed for one year from the date of purchase and includes all heater parts such as heating elements, controls, contactors, etc. This guarantee covers faults in manufacture and material only and includes the exchange of new parts supplied by the manufacturer or manufacturer’s agent after the faulty part has been returned to the same. The replacement of parts under warranty does not extend the warranty period beyond the original one year.


The guarantee does not cover defects caused by normal wear and tear, defects caused by improper installation, poor maintenance, or failure to follow the manufacturer’s instructions for installation, use, and care, or alterations made to the Sauna product. This guarantee is void if the heater is used improperly. Pool or spa water should not be poured over the Sauna stones, as chemicals are harmful to the heater. The Sauna room must be heated for at least 30 minutes before water is poured over the stones, and only one or two dippers full of water should be poured over the hot stones at one time. This guarantee will be void if a shower has been installed in the Sauna room.


This guarantee does not cover the delivery cost of the faulty part or costs of the person carrying out the repair in the field. If the Sauna heater is returned to the manufacturer or manufacturer’s agent in Portland, Oregon, within five years after the date of purchase, the agent will provide free labor for repair but will charge for parts if the date of purchase is past one year.


This guarantee will be void if installation and wiring are not carried out by a certified electrician or authorized and qualified service representative.
