4.5 Heater Guard (not supplied)
ŸThe heater should be guarded against accidental contact with a wooden guard similar
to the one shown below – according to the position of the heater within the cabin it may
need to be guarded on 2 or 3 sides.
ŸFix the guard in place around the heater by drilling and screwing accordingly.
It is important that the top rail of the guard is set at least 30 mm
below the rim of the heater such that it does not receive heat
radiation directly from the heater rocks.
NOTE
4.6 Sauna Stones
ŸDo not use the heater without sauna stones, otherwise it may cause a fire. These can be
supplied from any Dayliff dealer.
ŸDo not use ordinary stones which may emit harmful substances, easily break and do not
possess good heating capacity.
ŸWash the stones to clear the dust before putting them into the heater.
ŸAllowable size of stones is about 3-8cm.
Fig 12
Fig 13

13
ŸPut the larger stones at the bottom of stove compartment and the smaller ones on top.
ŸDo not pile them tightly so that air can flow freely.
Tightly placed stones decrease working time of the heater
element, the stones should plainly cover the heater element .
NOTE
ŸRearrange the stones in the heater at least once a year or twice if it is in frequent use
(maximum 500 hrs). Refer to diagram below on how to arrange stones correctly.
4.7 Insulation
ŸThe door, ceiling and walls of sauna room must be insulated.
ŸEnsure that moisture-protection is installed in the sauna room to prevent spreading
moisture to the other rooms or wall structure . Moisture-protection must be placed
between panel and heating insulation.
ŸMoisture and thermal protection should be installed from outside to inside, recommend
minimum thickness of the thermal insulation in the walls is 25mm and in the ceiling
50mm.
4.8 Air Ventilation of Sauna Room
ŸMix the cold air with hot air to relieve mugginess when bathing.
ŸDraw the fresh air around the heater to ventilate the sauna room.
ŸMove the heater to the farthest part of sauna room considering air ventilation of sauna
room, the inlet and outlet vent should be properly installed.
ŸThe inlet vent may be installed on the wall below the heater. When using mechanical
ventilation, inlet vent is placed 50cm above the heater or on the ceiling above the
heater the heavy cold air that is blown into the sauna room is mixed with the light hot air
from the heater ,bringing fresh air for bathers.
ŸThe recommended inlet should have a diameter of 5-10cm.
Fig 14

14
ŸThe outlet vent should be placed diagonally opposite to the inlet. It is advisable that the
outlet vent is placed under the platform in sauna room as far as possible from the inlet
vent.
ŸIt can be installed near the floor, or from the floor through to a vent to the sauna ceiling,
or under the door (to the wash room).
In this case, the sill slot must be at least 5cm and it is recommended there is mechanical
ventilation in washroom with twice the size of the inlet.
1. Air supply vent
2. Optional air supply vent if mechanical exhaust ventilation is used, the opening is located
50cm above the heater
3. Exhaust air vent
4. Drying vent, which is closed during heating and bathing, the sauna room can also be
dried by leaving the door open after bathing
5. If there is only an exhaust vent in washing room, leave an opening (Min 5cm), under the
sauna door and install mechanical ventilation
5. OPERATION
ŸBefore connecting to the power supply check the sauna heater and make sure there are
no flammable items on or around the heater, Note that on the first use the elements and
stones may smoke slightly and give off a smell – ensure the sauna cabin is well
ventilated.

SET
When used in commercial situations such as public buildings where the countdown timer is
set to come on in advance the door interlock switch must be connected as described in Fig
12 – before the timer is set to come on in advance the sauna room must be checked by the
operator to ensure there is no hazard such as combustible material left over the sauna stove
or in the sauna – then the sauna cabin door must be closed before the timer setting can be
made – if the timer begins when the door is opened, the controller will cancel the
countdown and won’t operate until reset.

7. MAINTENANCE
It is recommended that the sauna heater is inspected on a regular basis for any signs of
deterioration of its condition. Pay particular attention to both the fastenings, the condition
of the wiring and the electrical elements. It’s recommended that commercial operators
change the sauna stones at least once very 12 months.
If the stones have started to crumble this can cause the
elements to overheat and they should be changed for new
rocks.
