All installations and services must be performed by qualified service personnel.

D. OIL TANK & PIPING:

?WARNING: All local codes and ordinances take precedence with regard to tank and oil lines. In the

absence of local codes, all tanks and lines must be installed according to NFPA31 Standard for the

Installation of Oil Burning Equipment. All lines must have shutoff valves, a good pipe joint compound

approved for use with oil on all pipe threads, no kinks, no sharp bends, and be properly tested for leaks.

Flare fittings are recommended for tubing. Do not use compression fittings.

Burners are most commonly installed with a single stage fuel pump. This type of fuel pump, when connected with a supply line

only, is satisfactory where the fuel supply is level with, or above the burner thus permitting gravity flow of oil. When it is

necessary to lift oil to the burner, a return line should be connected between the fuel pump and tank. This requires insertion of

the "by-pass" plug into the fuel pump. If the lift exceeds approximately 10 feet, a two-stage pump should be installed with a

return line. When a return line is used with either single or two-stage pumps, air is automatically returned to the tank, making

the unit self-purging.

Use of continuous runs of heavy wall copper tubing is recommended. Always use flare fittings. Avoid use of fittings in

inaccessible locations. Avoid running tubing against any type of heating unit and across ceiling or floor joists.

If possible,

install the tubing under the floor.

Specific information on piping, fuel pump connections, lift capabilities, and tank installations are provided in the fuel pump

manufacturer's instructions.

Underground tanks should be located outside the building. If the underground tank is less than 275 gallons, the top of the tank

should be below all piping, in order to prevent oil discharge through a broken connection. Underwriter’s Laboratory’s

requirements now stipulate that all 275 gallon and larger tanks have a bottom outlet. This is to prevent the accumulation of

condensate, which causes the tank to rust. It is also recommended to use additives to prevent condensate accumulation, if the oil

supplier does not already use additives.

If the tank is above the burner, and gravity oil feed to the burner is permitted, a single line system may be used. The line should

have a gradual slope downward of approximately 1/2 inch per foot or more to a point directly below where it is connected to the

pump. Sloping the line will help prevent the formation of air pockets.

IMPORTANT:

An oil safety valve or a delayed action solenoid valve is recommended with all gravity feed oil supply

systems.

E. OIL FILTER:

Use an oil filter with the capacity to filter a 40-50 micron particle for all installations (except the 2-series, which requires a 10

micron particle filter). Install the filter inside the building between the tank shutoff valve and the burner.

Additional information for burner setup is provided in the burner manual that accompanies each burner. The burner

specifications provided in this manual take precedence over specifications provided in the burner manual that accompanies

burner.

The filter cartridge should be replaced at least once a year.

The filter body should be thoroughly cleaned before installing a new

cartridge.

F. WIRING:

All electrical wiring must be installed in strict accordance with local ordinances and codes. In the absence of local ordinances

and codes, all electrical wiring must be in accordance with the National Electrical Code

(ANSI/NFPA 70-1999, or latest

edition).
