This
unit
features
a thermostaticilly,
modulating
eurosit control
valve which requires
no
electricity
to
operate.
(Valve
shovrn
on
hge
SI; Once
you
have
selected
your
desired temperature
using
the control
knob,
the
temperature
sensing
O0tO
will controlthe
amount
of fuel consumed
accordingly. For
example
if
you
set
the
control
knob
in
the Hi
position
(110'R
the temperature
sensing butb
will reduce
the amount
of fuel
consumed
as
your
rooms
ambient temperature
rises.
lf
you
have
selected
a
lower
setting
and
you
rooms
ambient
temperature
rises above
that
setting the valve
will
"shut
off" the flow
of
gas
to
the
burner
until
the rooms
ambient
temperature
drops,
at which
time the valve will
automatically re-light.
Due
to
the
sensitivity
of the
thermostatic bulb, we
recommend
that
it
be
placed
in
as
cool a
location
as
possible.
One
possible
location
is to
place
the
bulb
on
your gas piping
as
far from
the stove
as
possible.The
coolgas
entering
your
home
will keep
the
temperature
sensing bulb cool allowing
maximum heat output.
