Specifications
NOTE:External
tank installations must comply with
the
National Fire Protection Association code
NFPA
31
or
locally applicable codes, such
as the
Uniform
Mechanical
Code, that
are
consistent
with
NFPA
31.
Check
with
your
local
building
official.
To
install
a
large capacity, gravity
fed
external tank,
follow
the
instructions below,
and
refer
to
Figure
23 for
one
possible installation.
Use of a
qualified installer
is
recommended.
•
Installation
height
of the
bottom
of the
fuel
tank
should
be 16
inches
or
more above
the
floor surface
on
which
the
heater stands.
This
ensures that inlet
fuel
pressure will
be
sufficient.
•The
top of the
fuel tank
should
be no
higher than
8
>2
feet
above
the
floor under
the
heater. Heights
above
8^2
feet will exceed
the 2.5 psi
inlet limit,
and a
pressure reducer will need
to be
installed
at
or
near
the
unit.
•The
horizontal length
of
piping should
not
exceed
100
feet
and
shoule
be
free
of
sharp bends
or
obstructions.
•Piping
should include
no
inverse U-type bends
(to
avoid
air
locks,which
could
block
the
fuel
supply).
•Only
%
inch
OD
copper tubing should
be
used.
The
tubing should
be
bent carefully
to
avoid crimping.
•A
fuel filter
is
recommended
for use on the
fuel line
near
the
tank,
and a
shut-off valve
should
be
installed
at the
tank.
• A
flare adaptor
can be
used
to
make
a
flared tubing
connection between
the
unit
and the
filter
at the
tank.
• The
fuel tank should
be
located
no
closer than
3
feet
to a
source
of
heat.
•The
fuel tank should have
an
opening
for
filling
on
the
top and
vent with
a
weather-proof
cap on the
side.
On
some tanks
the
vent
and
fill spout
use the
same opening.
When
using
a
gravity
fed
tank
to
supply
fuel,
the
inlet
pressure
to the
heater must
not
exceed
2.5
psi.
