(1)Gas Appliance Classifications for Approved Venting Methods based on CEN-report CR1749:2001
(2)Gas
connection
size
is
not
necessarily
the
supply
line
size.
There
is
a
difference
between
the
gas
connection
diameter
and
the
diameter
of
the
supply
line.
Always
use
the
most
adequate
dia
of
the
supply
line
to
minimize
the
pressure
drop
through
the
gas
pipes
–
if
necessary
reduce
the
diameter
of
the
supply
line
at
the
inlet
of
the
unit.
(3)Height
from
the
floor
to
bottom
surface
of
heater.
These
are
recommendations
only.
Positioning
of
unit
heaters
for
proper
performance
is
application
dependent.
Operation
is
affected
by
other
air
moving
equipment
in
the
space,
obstructions
to
the
airflow,
draughts
and/or
close
proximity
to
doors
or
windows,
etc…
Care
should
be
taken
to
avoid
mounting
the
heaters
above
these
recommendations,
unless
downturn
nozzle
options
are
used,
as
significant
stratification
may
occur
resulting
in
poor
floor
coverage
and
higher
energy
losses
through
the
roof
structure.
