Sauna room ventilation

In a sauna, the air should be changed about 6 times an hour. See
Figure 6.

It is recommended that ventilation openings meet the require­ments of UL Specifi cation 875. The minimum opening should be
determined using one of the following formulas:
For R< 31, V ≥ 9 .3
For R ≥ 31, V ≥ 0.3*R

where R = the fl oor area of the room in square feet and
V = the minimum vent size in square inches

ExampleVenting Calculation:
Room is 54 sq.ft.(9 ft. by 6 ft.) 54 is larger than 31.
Multiple 54 x 0.3 = 16.2 sq. in.
Vent size opening should be 4 in x 4 in.

Positioning the inlet vent

Install the inlet vent straight through the wall under the centerline
of the heater.

Figure 6: Positioning the air intake and exhaust vents

1. Inlet vent position.

2. Outlet vent position through the sauna wall.

3. Outlet vent position through the cavity.

4. Outlet vent position via duct.

Positioning the outlet vent

Position the outlet vent

• at the maximum possible distance from the air intake vent,
e.g. diagonally (see Figure 6).

• high on the wall or in the ceiling (see Figure 6).

• so that it vents into the space that the door and air intake
vent open into.

The outlet vent must have the same area as the inlet vent.
Ensure that the outlet vent is open.
Mechanical ventilation is not recommended due to the risk of poor
air exchange, which can negatively aff ect the heater temperature
cut-out.

Removing the Rock Guard

Unscrew the two screws on the side of the heater and lift the
rock guard upwards, see Figure 7. (This is necessary when fi lling
the stone compartment or cleaning the fragrance holder and air
humidifi er).

Figure 7: Removing the Rock Guard

Room construction

For safety and reliability, the following rules must be addressed.

• The enclosed WARNING: Reduce the risk of overheating
… warning plate must be mounted on or alongside the door
outside the sauna room at about eye level. Use the supplied
screws.

• The enclosed CAUTION: Reduce the risk of fi re … caution
plate must be mounted on the interior wall above the heater.
Use the supplied screws.

• No permanent locking or latch system is to be used on the
sauna door.

• Acceptable door fi ttings are: magnetic catches, friction catch­es, spring or gravity loaded closures. The door must always
open outwards.

• No shower may be installed in a sauna room.

• No electrical receptacle shall be installed inside the sauna
room.

• The heater should not be operated without its container prop­erly fi lled with rocks and the rock guard in place.

• If an intercom speaker is installed, it should be away from the
heater and as close to the fl oor as possible.

• If a room light is installed, it should be a surface mounted
bracket type. Wall mounted lights should be about 70” above
the fl oor. Ceiling mounted lights should be of an approved
type with a junction box that is remote to the fi xture itself.
Use only a fi xture that uses A.F. or fi xture type internal wiring.
A 60 watt bulb should provide suffi cient lighting.

• Fire sprinkler systems installed inside any sauna room should
be properly rated for sauna room temperatures.

• Always mount the heater according to these installation
instructions.

numbers of phases that are not listed in the wiring diagram Figure

18.

External ON/OFF switch (option)

The external ON/OFF switch can be positioned anywhere outside
the sauna, not to exceed 75 feet from the heater, to avoid voltage
loss in the cable. Voltage loss aff ects the LED indicator for heater
status (if built-in and connected to the switch).

For further information, see instructions supplied with the control
panel.
