Section
2:
Installation
To
install
a
large capacity, gravity
fed
external tank,
follow
the
instructions below.
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
insures 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.
This insures
that
inlet
fuel
pressure
will
not be
excessive.
• The
horizontal
length
of
piping
should
not
exceed
100
feet
and
should
be
free
of
sharp
bends
or
obstructions.
If
using lifter pump, max.
length
of
piping
is
164
ft.
•
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
tank,
and a
shut-off valve should
be
installed
at the
tank.
•
Flare connections should
be
used
at the
fusible
link
valve
connection
on the
heater
and at the
fuel filter
to be
installed
at the
tank.
• The
fuel tank should
be
located
no
closer than
3
feet from flue
pipe.
• The
fuel
tank should have
an
opening
for
filling
on
the top and a
vent with
a
weather-proof
cap
on
the
side.
On
some tanks
the
vent
and
fill
spout
use the
same opening.
55,
100,
and 250
gallon
tanks
must
contain:
•
Shut-off
valve
at
tank outlet
•
Disposable fuel filter (protects heater against
condensation
and
other impurities)
•
Fueling inlet (protected
by
weather-proof cap)
•
Ventilation outlet
•
Clearance
of at
least
3
from
any
source
of
heat
Allowable
Height Dimensions:
•
Bottom
of
tank-at
least
16"
above floor
holding
heater (maintains sufficient pressure)
• Top of
tank-maximum
of
&/•£'
above floor
holding heater (prevents excessive
line
pres-
sure
above
2.5
psi).
•
Position
of
Lifter-more than
8'
above fuel inlet
of
heater requires pressure reduction valve.
RECOMMENDATION
Pipe
fittings
in the
fuel supply
to the
Monitor
heating
systems should
be
sealed with pipe thread tape.
The

must
be
absolutely
air
tight.
275
gallons
and
bigger
tanks
should have
a 2.5
P.S.I,
max
pressure reducer
to
avoid excessive pressure
at
heater
inlet.

HEATER
INSTALLATION
The
Monitor heaters
can be

carpeting
or
other
combustible
flooring with com-
plete safety.
The

to an
electrical
outlet,
must support free
air
ciculation
(both internal

not
contain combustible materials
in the
heater's
immediate
