Sauna Venting and Framing Info

THINGS TO REMEMBER WHEN FRAMING YOUR SAUNA

We advise venting the sauna back inside the house rather than out to the outdoors

The main reason is that the barometric pressure outside is often different than indoors and this can create reverse flow bringing air from the outside in. Also, you always want to minimize penetrations to the outdoors. It might seem like a great way to heat your house, but the sauna will add very little positive heat to your home as by design it is meant to heat a small enclosed space. And, the sauna will not add any significant moisture to the adjoining air space. Even when you ladle water over the rocks you add very little actual humidity to the air. Saunas provide very dry air. The humidity of a sauna ranges from 10-35%.

Most importantly, the air coming into the sauna through the intake opening should be fresh and cooler than the heated sauna air. Fresh air also affects the sauna heater's thermostat and hi limit sensors. Otherwise, the sauna heater may sense that the room is prematurely hot and thus shut the heater down before the desired temperature is reached. Also the fresh air air will have slightly higher oxygen levels but do not be concerned with oxygen levels as the sauna rooms are no where near near air tight. Many saunas do just fine with a wide crack at the bottom of the door serving as the intake vent. See more information relating to this subject under our accessories: sauna vents and grills.

REINFORCE WALL TO BEAR THE WEIGHT OF THE SAUNA HEATER AND ROCKS

Place a 2"x6" board horizontally and on edge between the studs where the sauna heater will be mounted. The first 2"x6" should be 15" on center from the floor and another board should be at 25" on center from the floor. Allow a minimum of 4" of clearance from the front and sides of heater to any wood.

Polar or Helo Heaters 4.5-8 KW:

Place a 2"x6" board horizontally and on edge between the studs where the sauna heater will be mounted as above with the first board 17" and the second 23" on center from the floor. Allow a minimum of 4" of clearance from the front and sides of heater to any wood.

For all 2-8 KW heaters, allow at least 44" clearance above the heater.
For all 10-16 KW heaters allow at least 50" clearance above the heater.

SAUNA ROOM VENTING

Suggested optimal venting setup for a sauna room with heaters 2-8 KW have openings 4"x6". For heaters 8-16 KW, opening sizes are 6"x8". Place one below the heater which will serve as the intake vent and the other as far away as possible in the opposite upper corner of the room. Venting your sauna serves several purposes.

  1. It creates a convection flow that keeps the room a more uniform temperature from the top to bottom.
  2. You are assured of a good supply of oxygen to the users while in the sauna.
  3. Ventilation will assist in drying out the sauna room after it has been used.

Frame air inlet and exit vent openings approximately 3" from floor/ceiling and at least 3" from the corner.
