Installation of a tunnel sauna heater.
For sealing brickwork and tunnel part we recommend the
use of a mineral wool slab, which provides moving space
required for thermal expansion. A tunnel model is connect-
ed to the stack from the top of the sauna heater.
In connection with the sauna heater installation, ensure
that the heater stands firmly on its base and that all of the
safety clearances mentioned in these instructions have
been observed correctly.
PROTECTION OF THE FLOOR IN FRONT OF THE SAUNA HEATER
Floors made of inflammable material must be protected
with a metal plate that reaches at least 100 mm to both
sides of the sauna heater and 400 mm in front.
