Harvia Heater Installation Guide
Revised April 2017

Your Almost Heaven Sauna includes a genuine Finnish heater that is manufactured by Harvia Oy, the world
leader in exceponal sauna heaters. This brief guide is intended to supplement the manufacturer’s manual
and will give you simple instrucons on how to install the Harvia heater in your Almost Heaven Sauna. A li-
censed electrician should perform all electrical work, and Almost Heaven Saunas is available to assist with
any quesons you or your electrician may have. You may contact us at 888.355.3050 or 304.497.3991 for
technical assistance.
4.5kw and 6.0kw Heaters
 30-amp double pole breaker
 10/2 wire if under 30’ from power source; 8/2 wire if over
 Hard wire directly to heater
 Do not use GFCI with this heater
 Use copper wire with 90°C insulaon
8.0kw Heaters
 40-amp double pole breaker
 8/2 wire
 Hard wire directly to heater
 Do not use GFCI with this heater
 Use copper wire with 90°C insulaon
2. Drill hole to bring power to sauna heater. A
typical locaon would be on the wall below and
behind where the heater will be mounted, but
the wire can come in at any point most conven-
ient and accessible to the power source. Bring
conduit into sauna in compliance with local
electrical codes. (Heater will be centered over
the vent holes near the oor of the sauna.)
1. Aer unpacking your Harvia heater, detach
the stone guard from the top by removing the
two screws that aach it to the backside of the
heater. Aer the screws are removed, hold the
stone guard at the front of the heater and pull
up rmly and quickly. The guard will release
from the heater and will be reaached in the
same way aer the stones are inserted. Screw Locaon

6. Find the wire opening slot
and place the coated poron
of the sensor wire through
the slot. This will allow the
sensor to be placed on the
back wall of the sauna.
7. Wire the heater according
to the diagram. All wiring
should be done by a licensed
electrician. Replace boom
cover once wiring is com-
plete.
8. Mount the heater with screws
provided so that the boom of
the heater is 7” from the lowest
point of the sauna room oor.
Install the heater fence below
the level of the sauna stones.

3. The temp sensor housing is
aached to the heater element
with a zip e. Clip the zip e
and remove the sensor hous-
ing from the heater. Set aside
the temp sensor housing for
now.
4. Turn the heater on it’s back and
remove the boom cover to ex-
pose the temp sensor.
5. Remove the temp sensor and
carefully uncoil the sensor cable
that is aached to the sensor.

10. Fill the heater with provided stones. NOTE: Only use the stones
provided with your heater and never operate the heater without
stones. Wash the stones with water and then place between and
around the heang elements. The stones will touch the elements
but should not be forced into place. Use the smaller stones rst; FILL
UNTIL STONES COVER THE ELEMENTS COMPLETELY. You may not
need all of the stones.
NOTE: Stones should be placed loosely within the heater so that there is good heat circulaon around and
through them. The stones should cover the heang elements, but you want to be able to see them a lile bit
to verify that they are turning red. Pouring water over over-exposed elements could cause heater damage.
TIMER OPERATION
To turn the heater on, turn the On|O and Timer dial clockwise past the small “1” and then back slowly to
the large “1” unl you hear a click. The sauna heater should now begin heang and will do so for one hour
and then automacally shut o. Repeat this step if you wish to have the heater connue heang aer it
shuts o.
The On|O control also funcons as an 8-hour delay mer. You can set the heater to come “on” up to 8
hours later. If you wish to have the heater turn on in two hours, turn the mer clockwise to the small “2”.
The heater will then begin heang in two hours. Follow the same procedure for delayed startup up to eight
hours in advance.
Since the heater will always shut o aer one hour, you may need to turn the heater on again while in the
sauna. Never stay in the heated sauna for extended periods of me. Consult the safety instrucons in the
heater manual before using the sauna.

9. At this point, it’s me to switch on the heater, so turn on the breaker. There is a non-toxic coang on the
heater elements, and the purpose of this preliminary heang stage is to burn that coang away. It is normal
for smoke to appear, so keep the door open to prevent it from leaving a black residue on the ceiling. Run the
heater for 3-5 minutes or unl it stops smoking, and then turn it o and allow the elements to cool.

13. TESTING THE SAUNA HEATER
Turn the temperature control to the desired seng. Generally the heater will be operated with the tempera-
ture control to the “max” seng. Turn the heater “on” according to the TIMER OPERATION instrucons on
the previous page. Within 5 minutes you should be able to feel heat from the heater elements when holding
your hand over the heater. (If heater does not heat, refer to troubleshoong informaon on the following
page.) Be sure to let the sauna heat for at least one hour before using the sauna.
11. Mount the metal temp sensor
housing vercally on the wall and
12” to the right or le of the heat-
er. For barrel-shaped saunas:
Mount the housing so that the top
is 4.5” below the upper horizontal
wall support. For a box-shaped
saunas: Mount the housing 15”
down from the ceiling.
12. Conceal the temp sensor by
mounng the sensor cover. Place
the cover over the temp sensor
and mount with a single screw that
is provided. Carefully posion the
trim over the sensor cable so that
the cable is concealed within the
groove of the trim piece. Aach
trim to wall with included nish
nails.

TROUBLESHOOTING
1. If sauna heater does not operate aer inial installaon and wiring
 Check breaker to be sure it is on.
 Be sure mer is set properly and is “on”. (Step #9)
2. If sauna heater operates but sauna room does not come up to temperature
 Check to be sure breaker is on.
 Check to see that the mer has not wound down. If so, reset.
 Are the stones placed loosely around the elements? Stones packed too ghtly can re strict airow and
reduce heang capacity.
 Check for heat loss. Are the high vents closed? Are the oor drains plugged? Are the hinges of the door
ght?
 Check high limit reset buon below heater.
3. If sauna heater has been in operaon but then ceases to operate.
 Allow at least 30 minutes for sauna to heat up.
 Is the thermometer/hygrometer located on the wall opposite the heater, 12” down from the top of the
sauna room? Temperature readings will vary, but the proper place to measure the temperature is about
12” from the top of the room.
 Was the proper wire size and amp size used?
HIGH LIMIT CONTROL
Your Harvia Heater is equipped with a built-in high-limit control, which is a safety device. If an abnormal
heang condion should occur, the heater will automacally shut o. Once the room as cooled, manually
reset the heater by pushing the reset buon.
To reset the high-limit, locate the reset buon on the boom front of the heater. Push the buon upwards
unl you hear a click, which indicates that the heater is again acvated. If the reset buon connues to trip,
give us a call at 304-497-3991. Be sure a GFCI was NOT installed.
