Where can I find the manual?
Can the Harvia M3 be connected to a masonry chimney?
Yes, the M3 has rear and upper connection options, and can be tied into an existing masonry chimney in good condition. You will likely want and need a chimney liner if you don't already have one - consult your local building department.
Can you install this on a wood floor?
Yes, but the Harvia Protective Bedding must be used.
Can it be connected to a masonry chimney?
Make an opening in the fireproof wall for the flue connection. Notice that the opening has to be at the correct height, if you intend to use, for instance, a protective bedding. The hole should be slightly larger than the flue connecting pipe. A suitable gap around the connection pipe is ca. 10 mm. It is advisable to round off the inner corners of the flue opening to ensure that the combustion gases can flow freely to the flue.
Refer to manual for instructions on connecting to top of M3 to chimney.
Can it be installed on an uneven floor?
The adjustable legs enable the stove to be installed firmly on an inclined floor. The adjustable range is 0–30 mm. Unscrew the adjustable feet to an extent that allows them to be adjusted using a wrench (17 mm) when the stove is in position.
Do I need to preburn outside the sauna first?
Yes, as with all wood burning sauna stoves you should set it up outside on a calm day and 'preburn' to cure the paint until you can't smell any odors. Timing will depend on how hot you get it, but we like to get a good burn going for 4 hours before installing. Be sure to let the stove cool off before installation, preferably overnight.
Does it need a vent? Where?
Yes, all wood stoves require ventilation for proper combustion. Harvia recommends an intake vent behind stove, very low on the wall and a exhaust vent high on the opposite wall.

The Harvia Pro Series is the value line for medium saunas.

Very happy with the M3. First off Ben did a great job answering all of my questions and walking me thru the best stove selection for my build. Shipping was fast and painless. The stove takes 30 minutes to heat up and doesn’t use as much wood as I imagined. I also purchased the heat shield for clearance and with the help of a friend install was quick and easy. I wouldn’t hesitate to work with Ben from sauna market place again. Cheers!

My family is loving the Harvia M3, heat shield and stones! It was an absolute pleasure doing business with you! On top of the most competitive price, everything arrived on time and was in perfect condition.
Here’s a couple pics of my build. I built a mobile sauna (using old camper running gear) as I wanted the flexibility to use it at home and at recreational property I have near by. Dimensions are roughly 7×10 including a small changing room. The interior is all local Michigan white cedar.
The Harvia stove combined with heat shield allowed me to maximize my space and heats up the sauna very quickly.
It was a great project for me and my boys which we wouldn’t be able to afford as quickly without your help.
