BUILDING INSTRUCTIONS

The importance of correct sauna ventilation.
Incorrect sauna ventilation can result in hot floors and benches, scorched
walls and ceilings (the temperature limit control is triggered)! So we do urge
you to follow our instructions for sauna ventilation carefully.
Adjust the air outlet to evacuate 6 8 cu.m. of air per person, per hour, when
the sauna is in operation.
Mechanical sauna ventilation is not to be recommended, as the forced air
supply can cause a fire hazard through the wooden panelling drying out.
Fig. 18,19 Inlet vent always directly below the heater.
The inlet vent should be driven straight through the wall directly below the
centre of the heater. The cross-section of the vent for a family sauna is
approx. 125 Sq.cm., for larger saunas approx. 300 sq.cm.
Fig. 20 The outlet vent should never discharge directly
into the open air.
Position the air inlet and outlet vents as far away from one another as
possible (diagonally opposite). The outlet vent should be located high on a
wall or in the ceiling, and should have the same cross-section area as the
inlet vent.
Spent air should always be led back into the same room from which it is
drawn into the sauna it must never be discharged directly into the open
air. In this way, the air flowing from the sauna is continually being
replenished in the room outside. This thermal ventilation method always
works, no matter whether the pressure in adjacent rooms is negative or
positive.
If there is a gap above the sauna ceiling, do not seal it. To ventilate a cavity
above the sauna, drill or cut at least one ventilation hole into the cavity
through the wall on which the sauna door is located.
Alt. A: Outlet vent through the sauna wall (seen from above). The vent is
placed high up, near the ceiling.
Alt. B: Outlet vent through the cavity above the sauna ceiling (seen from
the side).
Alt. C: Outlet vent through a drum under the ceiling in the sauna (seen from
the side). The outlet duct should be placed at an angle between the ceiling
and the wall. The drum can be built of wooden panelling and have the same
area as the outlet vent.
Fig. 21 - Solenoid valve box
From the factory, the valves for emptying and refilling are assembled as in
fig. 21a. If the placement of sewer and water connection is different, this is
easily changeable. Begin by removing the valves from the tracks they are
located in (Fig. 21b). The bottom valve needs to be adjusted before both
valves are fitted back. This is done by loosening the two screws shown in
the picture and rotate the top of the valve half a turn (Fig. 21c). Unscrew the
two screws and place both valves in the grooves. Now, the direction of
emptying and filling have changed.
Fig. 22 Recommendations for sauna construction:
A. Floor frame, corner posts, studs, ceiling frame.
B. Battens, rafters, vents.
C. 50 mm mineral wool as heat insulation, approx. 20 mm air gap between
insulation and outer wall.
D. 12 mm wooden panel in walls and ceilings. There should always be at
least 50 mm of insulation behind the wooden panel; no other material,
such as particle board or plaster, may be used.
E. Bonded, non-slip plastic floor-covering, extending approx. 50 mm up the
walls behind the wooden panelling.
F. Inlet vents should always be fully open. May be fitted with a shuttered
vent on the outside.
G. Outlet vent, can be fitted with a sliding hatch to adjust through-flow.
H. Benches of at least 22 mm thick knot-free pine (alternatively aspen, lime
or obeche).
I. Drainage channel (recommended in public saunas). Never place a
drainage channel or drain under the sauna heater.
Fig. 23 Heater guard.
The stones and the top of the sauna heater get very hot! In order to reduce
the risk of accidental contact, Tylö always recommend that a heater guard
be fixed as shown in the sketches.
Some words of advice:
There should never be a drain in a sauna. However, all public saunas
should have a drainage channel (I, fig. 19) connected to a drain out-side
the sauna (no drainage channel is needed in a private sauna).
If the sauna has a window in the door or wall, treat the lower moulding
with boat varnish and seal the joint between the glass and the moulding
with a water-resistant silicone sealant. This prevents any condensation
on the glass from seeping into the wood.
Varnish the threshold and door handles a few times with boat varnish to
maintain the finish and simplify cleaning the sauna. Benches, decorative
edging and back supports should be oiled on both sides with Tylö sauna
oil (this is particularly important in the Tylarium). Note: All other wood in
the sauna should be untreated.
Install floor decking only if the floor is slippery. Floor decking is im-
practical and prolongs the drying time for any water spilt on the floor.
Treat the bucket and ladle with boat varnish, or oil them with Tylö sauna
oil. The bucket will remain watertight and the wood will be beautifully
preserved. Never leave the wooden bucket in the sauna after a sauna
bath.
Before you enjoy your first sauna bath, heat the sauna room up to 90° C
and leave the heater to run for about 1 hour. This will rid the room of that
Clean your sauna regularly. Scrub the benches and floor with soft soap. It
is a mild, gentle detergent and leaves a pleasant fragrance.

General Information

Fig. 24. Filling the stone compartment.
stones can damage the unit. Fill the stone compartment around the
elements from bottom to top, stacking the stones approx. 50 mm above the
front edge at the top of the unit. Do not press the stones into place.
Fig. 25.
Never place stones above the side air chambers. This prevents air
circulation, the unit becomes overheated and the temperature limit control is
triggered.
Check the stone compartment at least once a year.
This is especially important for public saunas and saunas in frequent use.
Remove all stones from the compartment. Clean any small stones, grit,
gravel and chalky deposits from the bottom of the stone compartment. Use
only stones which are whole and intact, replacing them when necessary
with new dolerite stones.
Temperature limit control.
Tylö sauna heaters have a temperature limit control built into the terminal
box on the heater. This is activated automatically if there is any risk of
overheating. More often than not, the cut-off is triggered because of
incorrect sauna ventilation or an incorrectly located sauna heater. Call an
expert to reset the temperature limit control.
Fig. 26.
Sprinkling water on the stones
Must always be done with a ladle onto the stones, never with a hose or
bucket. Note: The stones must be hot.
Fragrant sauna bath can be obtained by using fragrances. Splash a
few drops of essence in the fragrance dispenser.
In order to obtain a pleasant because moisture in the sauna fill the
internal humidifier with water before the sauna is switched on.
A. Fragrance dispenser
B. Humidifier
If neccessary, clean fragrance dispenser and humidifier . Lift it off and
rinse under running water.
