Because
a
large
quantity
of
oxygen
is
used
during
burning,
the
installation
site
for
the
water
heater
must
be
well.
During
operation,
the
water
heater
will
give
off
fumes;
therefore,
a
chimney
must
be
installed
to
the
water
heater
to
extract
the
fumes
outside
the
house
and
keep
fresh
air
in
the
house,
to
ensure
complete
burning.

When
in
use
with
natural
gas:
in
case
of
low
gas
pressure,
it
is
highly
possible
that
a
“flame
‐
retrace”
will
be
created.
This
can
cause
a
carbon
build
‐
up
in
the
burner.
Should
this
occur,
the
blue
flame
becomes
yellow
and
the
level
of
carbon
monoxide
notably
rises.
In
such
a
case,
stop
using
the
heater
and
contact
the
gas
supplier.
