A TYPICAL HEATER INSTALLATION - FIGURE 9
Refer to pages 2, 3, and 4 in this manual for more information about burner series numbers and characteristics for adaptability to the following systems.
SYSTEM TYPES
Single Stage, Supply Line Only: The bottom of the oil storage tank must be above the level of the fuel unit, fig. 10. The fuel oil will flow by gravity to the burner. A single pipe is run between the tank and fuel unit. Burner Series No. 940 is from this type of service as shipped (the bypass plug is not installed).
A GRAVITY FEED, SUPPLY LINE ONLY, INSTALLATION
FIGURE 10
If the bottom of the oil tank is at least 2 inches higher than the plug opening at which the supply line connects to the fuel pump, a
•A two stage pump may be used on one line, gravity feed installations. The pump will function as a single stage unit when the

If the tank bottom is no lower than 10 feet below the plug, a single stage pump may be used but, it must be a two line system with maximum tubing runs (which includes lift) as shown in Table 6.

Two Stage, Supply and Return Lines: This system, fig. 12, is required when long lines and high lifts (requiring up to 20" of vacuum and 10' vertical lift) are encountered. Burner Series No. 941 is used in this service. Bypass plug must be installed.
A TWO STAGE (HIGH LIFT), SUPPLY AND RETURN
LINE INSTALLATION - FIGURE 12
If the tank(s) bottom is lower than the plug by more than 10 feet, a two stage pump with a two line system must be used with maximum tubing runs (which includes lift) as shown in Table 7.

MULTIPLE HEATER FUEL LINES
Where two or more heaters form a water heating system, each burner shall have an entirely separate oil supply line from the tank to the burner.
BURNER INSTALLATION
GENERAL
An oil Burner Certificate is packed with the oil burner. Following the burner manual installation the necessary tests shall be performed and the results recorded on the certificate, see BURNER CERTIFICATE. The certificate and this instruction manual must be left with the user for future reference. Check to be certain the heater and burner model numbers are alike and the oil pump characteristics are proper for the job. See IDENTIFICATION, page 3.
