censed electrician should perform all electrical work, and Almost Heaven Saunas is available to assist with

Drill hole to bring power to sauna heater. A
typical location 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 floor of the sauna.)
1.
After unpacking your Harvia heater, detach
the stone guard from the top by removing the
two screws that attach it to the backside of the
heater. After the screws are removed, hold the
stone guard at the front of the heater and pull
up firmly and quickly. The guard will release
from the heater and will be reattached in the
same way after the stones are inserted.
