must
be
connected
to
the
pressure
regulator
outlet
thread
(5)
by
turning
it
to
the

using
a
SW17
spanner.
Before
using
the
gas
heater,
check
that
there
are
no
gas
leaks
with
the
use
of
a
gas
leak
detection
spray.
Do
not

For
this
purpose,
check
all
connections
with
the

valve
open
and
the
gas

Oxygen
deficiency
safety
device
The
furnace
is
equipped
with
a
pilot
flame,
which
also
serves
as
an
oxygen
deficiency
safety
device.
This
automatically
switches
off
the
furnace
before
the
carbon
dioxide
content
in
the
air
reaches
the
