period of one year from the original purchase date.

This limited warranty covers faults in manufacture and material 

only, and includes the exchange of new parts supplied by the 
manufacturer or the manufacturer’s agent, after the defective parts 
are returned to Steamist. The replacement of parts under warranty 
does not extend the warranty period beyond the original one year

the original, purchase date. All costs for removal and reinstallation of

heater caused by normal wear and tear, damages caused by 
improper installation, improper use and care or alterations made to 
the sauna product.

This limited warranty is void if the heater is used improperly. 

Chemically treated water, such as spa or pool water should not be 
poured over the sauna stones. The sauna room must be heated for a 
minimum of 30 minutes prior to the application of water to the sauna 
stones. The limited warranty is void if a shower or faucet has been 
installed in the sauna. Damages resulting from the misuse of the 
heater will not be covered in the warranty.

      sauna; and a carpet promotes the spread of foot diseases 

such as athlete’s foot. 

8.   In new construction, a floor drain should also be provided, 

especially in commercial saunas for sanitary cleaning and 
maintenance.

9.   Seal wood around glass in door—inside and outside-

with Thompson’s Water Seal to prevent warpage.

10. When sauna wood becomes stained from perspiration, the 

wood may be lightly sanded with fine sandpaper to restore 
beautiful appearance. We do not recommend stains or 
sealers as toxic vapors may appear when heated.

11. The sauna room will heat faster if the higher vent is kept in 

a closed position when heating. The lower vent may 
always be kept in an open position.

12. Required warning signs should be posted according to the 

instructions.
