Wood Fired Sauna Heater Installation Guide
For Family16 Wood Fired Sauna Heaters
-
SAUNA Size for Heater
The recommended sauna room volume is 10 -18 cubic meters (350-635 cu. ft). When determining the volume of the sauna, please note that 0.8 - 1.5 cubic meters must be added to the volume for every square meter of stone wall and the stove chosen according to the total volume.
Ventilation is important to pleasant sauna bathing. Fresh air venting should be located as near the stove as possible.
-
FOUNDATION
These wood stoves do not require a concrete foundation but can be installed also on a wooden floor PROVIDED THAT GIVEN SAFETY DISTANCES ARE FOLLOWED. (See item 4).
-
FLUE CONNECTION
Diameter of the flue outlet is 120mm (4 5/8" measured outside-to-outside of flue flange). The stove can be connected either from the back or from the top of the stove.
- The distance from the center of the rear outlet to the floor is 600mm (24").
- Using the center of the top flue outlet, the distance from the back surface of the stove is 105mm (4.2") on the Family 16.
- NOTE: If your stove has a water cistern installed, you must use the top outlet on the stove, the rear outlet will be obstructed by the cistern.
- From center of the vertical outlet to the back surface of the stove, the distance is 100mm (4 inches).
A factory-manufactured chimney may be used instead of a brick chimney. The manufacturer's instructions and specified clearances regarding safety distances must be observed. Regardless of what chimney is used, the diameter must not be smaller than the flue diameter of the stove.

SAFETY DISTANCES TO COMBUSTIBLE MATERIALS
Front 1000mm (40 inches) Sides 500mm (20 inches) see note 1 Back 500mm (20 inches) see note 1 Upwards 1200mm (48 inches) see note 2 Bottom 250mm (10 inches) see note 3 Note 1: The safety distances can be reduced by 50% when using single light shielding and 75% when using double light shielding.
Note 2: The safety distances can be reduced by 25% when using single light shielding and 50% when using double light shielding.
Single light shielding can be provided by a non-combustible fibre-reinforced cement plate at least 7mm (1/4") thick, or a sheet metal plate at least 1mm thick and attached with sufficient fasteners.
Double shielding can be provided with two of the above plates.
The sheets should be attached to the back, and to each other with screws. A space of at least 30mm (1 1/4") should be left between the protecting plate and the surface needing protecting.
Brickwork 55mm (2") thick, 30mm (1 1/4") from the surface needing protecting is equivalent to single light shielding. Similar brickwork 110mm (4") thick, 30mm (1 1/4") from the surface needing protecting is equivalent to double light shielding.
A wooden floor must be protected. A metal sheet must be at least as wide as the stove, and extend 400mm (16") in front of the stove.
A free space of 1000mm must be left in front of the stove for maintenance.
REGULATIONS OF LOCAL FIRE AUTHORITIES MUST BE OBSERVED IN ADDITION TO THE ABOVE INSTRUCTIONS.
-
FUEL
Wood and paper can be used. Chipboard, fiberboard, and plastics must not be used as fuel.
-
HEATING
The inner parts of the stove have been treated with protective paint, and the stove must be preheated before placing the stones. Be sure to provide adequate ventilation during the preheating process.
The swing of the door can be changed by lifting the hinge pin to release the lower hinge and pulling both the door and the hinge pin downwards from the frame. Install the door and the hinge pin in the upper hinge. Place the door so you can drop the hinge pin on the lower hinge. Fasten the handle of the door.
Sauna stones should be washed before placing on the stove. Place the bigger stones at the bottom and not too tightly together so as not to impair thermal conduction. When the stones begin to crumble or deteriorate they should be replaced. Stones measuring 1.5" to 3" will be a good size.
Start the fire with small, dry firewood and leave the fire chamber partially filled to ensure a good fire. The intensity and combustion time are adjusted through the air inlets in the fireplace door.
When the inlet openings are wide open the combustion time will be the shortest and the fire will burn the hottest. This should be used only when starting the fire.
ONCE THE FIRE BURN HAS BEEN ESTABLISHED, YOU SHOULD RESTRICT THE AIR FLOW BY CLOSING THE DOOR VENTS.
This will prolong the burn time of the fire and reduce the intensity of the fire, yet provide a stable temperature in the sauna. By closing all air openings you will get heat from the stove itself and not just the flue and the chimney. Do not allow the stove-top or chimney flue pipe to become red-hot.
-
MAINTENANCE
Ashes should be removed periodically so as to not restrict air flow. Also check the condition of the flue and flue pipe. Sweeping of the flue pipe should be done as required.
