Installation
FUEL TANKS AND FUEL LINES
Fuel tanks and fuel lines must be installed in accordance with requirements of NFPA 31.
If fuel lines are under 30 feet in length, it is satisfactory to use 3/8" O.D. copper tube. Never use tube smaller than 3/8" O.D. If the lines are over 30 feet in length, we recommend 1/2" O.D. tube. Use good flare connections on the fuel lines and, whenever possible, avoid splicing the tube. Never make a splice or joint underground. Whenever possible, avoid overhead lines; avoid kinks and traps in the lines. Do not fasten fuel lines directly
to floor joists, sills, or girders. Whenever possible, support fuel lines with
SINGLE LINE SYSTEM |
|
When fuel does not have to be lifted from tank to |
|
burner use a single line hookup. A single line system | FIG. 18 |
can be used when outlet on fuel tank is higher than | |
inlet on burner. |
|
TWO LINE SYSTEM | FUEL LINE |
| |
To lift fuel from tank to burner use a |
|
On outside buried tanks, install a supply line from tank |
|
to burner and return line from burner back to tank. The |
|
supply line is called the suction line. The suction line |
|
should extend down within a few inches of the bottom |
|
of fuel tank. |
|
OIL FILTER |
|
A fuel filter should be used with either an outside or |
|
inside fuel tank. In all cases install the filter in |
|
accordance with local codes. The filter should always |
|
be installed inside, near the furnace. An inside tank and |
|
any internal or external fire or flame appliance being |
|
served by the tank must be at least 5 feet away from |
|
the furnace. New oil replacement cartridges should be |
|
installed annually or as required. Always use the new |
|
gasket that is supplied with the replacement cartridge. |
|
Tighten the top of the filter carefully and check the |
|
gasket for proper fit. |
|
FILL AND VENT PIPES |
|
Fuel tanks must be equipped with a fill pipe and a vent |
|
pipe. Fill pipes should be terminated in a convenient place |
|
for filling. They should be equipped with a watertight cap. |
|
It is recommended that |
|
The vent should extend outdoors served by the tank and |
