A2EA-6520 4 GPH 100-150 PSI 3450 RPM

3 GPH 150-200 PSI 3450 RPM

The end of the air tube should normally be 1/4” back from the inside wall of the combustion chamber. Never allow the leading edge of the retention ring to extend into the chamber, unless otherwise specified by the appliance manufacturer.

Bolt the burner to the appliance using the factory-welded flange.

Connect Fuel Lines

Do Not Install By-pass Plug with 1-Pipe System

Failure to comply could cause Immediate pump seal failure, pressurized oil leakage and the potential for a fire and injury hazard.

yThe burner is shipped without the by-pass plug installed.

yInstall the by-pass plug in two-pipe oil supply systems ONLY.

The burner is supplied with either a one-stage pump or a two-stage pump based on the oil supply system requirements. Consult the instructions provided with the pump for installation specifications.

When installing a one-pipe system, connect the inlet line to the pump inlet. The fuel pump may be installed with gravity feed or lift. The maximum allowable lift for a single pipe installation is 8 ft.

When installing a two-pipe system, remove the 1/16” pipe by-pass plug from plastic bag attached to fuel unit. Remove 1/4” plug from return port. Insert and tighten the by-pass plug. Attach return and inlet lines. The return line should terminate approximately 3 to 4 inches above supply line inlet. Failure to do this may introduce air into the system and could result in loss of prime.

Electrical Shock Hazard

Electrical shock can cause severe personal injury or death.

yDisconnect electrical power before installing or servicing the burner.

yProvide ground wiring to the burner, metal control enclosures and accessories. (This may also be required to aid proper control system operation.)

yPerform all wiring in compliance with the National Electrical Code ANSI/NFPA 70 (Canada CSA C22.1)

○Refer to appliance manufacturer’s wiring diagram for electrical connections.

Burner installed at jobsite

○Refer to Figures 8a and 8b, for typical burner wiring, showing cad cell primary controls. Burner wiring may vary, depending on primary control actually used.

○Refer to the appliance manufacturer’s wiring diagram prior to connecting the burner wiring. All wiring must be in accordance with the latest revision of National Electric Code NFPA 70 and all local codes and regulations. In Canada, all wiring is to be in accordance with the Canadian Electrical Code, Part 1.

The 7505 primary control with valve-on delay (pre- time) and burner motor-off delay (post-time) requires a constant 120 volts AC power source supplied to the BLACK wire on the control. The RED wire goes to the appliance limit circuit. Please note that other control manufacturers may use different wire colors for power and limit connections.

Special wiring required with covered burners

The mounting plate is not a conduit connection point. Pass conduit and attached connector through the opening in the mounting plate and attach it directly to the burner-mounted 4x4 electrical box.

If attaching a burner cover to a previously installed burner, attach the mounting plate and then slide the conduit into the “J” shaped conduit slot.
