EGULATIONS
1.
It
is
forbidden
to
install
this
water
heater
in
a
closed
room.
It
must
be
installed
in
a
well
‐
ventilated
area
larger
than
7.5
㎡
.
Because
the
water
heater
requires
a
larger
quantity
of
oxygen
when
working,
the
area
should
have
a
minimum
air
‐
induction
opening
of
0.06
㎡
(20x30
cm).
2.
Do
not
install
the
water
heater
in
a
location
with
strong
wind
(unless
it
is
protected
from
the
wind);
otherwise,
the
flame
may
go
out
or
cause
incomplete
burning.
3.
It
is
forbidden
to
install
the
heater
outside
if
it’s
not
protected
from
wind
and
rain,
because
wind
and
rain
may
put
out
the
flame;
Moreover,
the
appliance
might
get
frozen
and
damaged
in
a
cold
winter
season.
4.
A
water
supply
with
a
minimum
0.02Mpa
water
pressure
is
required
on
the
installation
site
to
ensure
the
normal
operation
of
the
water
heater.
5.
We
recommend
a
cold
water
valve
be
installed
close
to
the
water
heater
for
maintenance
convenience.
See
Fig

8.
Make
sure
a
proper
gas
pipe
are
installed
and
make
sure
that
the
pipe
remains
airtight
and
the

is
30mbar,
2h/kg
