Burnham MST513 Section Viii System START-UP, Always Inspect Installation Before Starting Burner

Section VIII: SYSTEM START-UP

WARNING

All boilers equipped with burner swing door have a potential hazard which can cause severe property damage, personal injury or loss of life if ignored. Before opening swing door, turn off service switch to boiler to prevent accidental firing of burner outside the combustion chamber. Be sure to tighten swing door fastener completely when service is completed.

A.ALWAYS INSPECT INSTALLATION BEFORE STARTING BURNER.

1.Verify that the venting, water piping, oil piping, and electrical system are installed properly. Refer to Installation Instructions contained in this manual.

2.Confirm all electrical, water and oil supplies are turned off at the source and that the vent is clear from obstructions.

WARNING

Completely read, understand and follow all instructions in this manual before attempting start up.

B. FILL HEATING SYSTEM WITH WATER.

NOTICE

It is important, especially in a steam system, to properly remove the oil and dirt from the system. Failure to clean the system can result in erratic water lines and surging.

CLEAN HEATING SYSTEM if boiler water or condensate return water is dirty or if erratic water lines or surging exist after a few days of boiler operation.

Refer to Maintenance and Service Instructions Section of this manual for proper cleaning instructions for steam and water boilers.

1.STEAM BOILERS — Fill boiler to normal water line. Refer to Figure No. 1.

WARNING

The maximum operating pressure of this boiler is posted on the ASME Data Label located on the top of the boiler. Never exceed this pressure. Do not plug relief valve.

C.CHECK CONTROLS, WIRING AND BURNER to be sure that all connections are tight and burner is rigid, that all electrical connections have been completed and fuses installed, and that oil tank is filled and oil lines have been tested.

D.SET CONTROLS with burner service switch turned

“OFF”.

1. SET ROOM THERMOSTAT about 10° above room temperature.

2. PRESS RED RESET BUTTON on front of burner cover, hold for one (1) second and release to reset primary control.

3. On STEAM BOILERS:

a. With an L404F1367 - set cut-out pressure (MAIN scale) on the pressure limit for (1) PSI and differential pressure (DIFF.) for .5 PSI. These pressures may be varied to suit individual requirements of the system.

4. On STEAM BOILERS WITH TANKLESS DOMESTIC WATER HEATERS, set boiler water temperature dial on L4006 operating control at 190°F (max.). Set differential at 10°.

E. ADJUST OIL BURNER BEFORE

STARTING.

1. CHECK BURNER AIR BAND, AIR SHUTTER AND HEAD SETTING (if applicable), readjust if necessary, see Table 8 at rear of manual.

2. OPEN ALL OIL LINE VALVES.

3. Attach a plastic hose to fuel pump vent fitting and provide a pan to catch the oil.

4. OPEN FLAME OBSERVATION PORT COVER on burner swing door.

F. START OIL BURNER.

1. Open vent fitting on fuel pump.

2. PRESS RED RESET BUTTON on front of burner cover, hold for one (1) second and release to reset primary control.

3. TURN ‘ON’ BURNER service switch and allow burner to run until oil flows from vent fitting in a SOLID stream without air bubbles for approximately 10 seconds.

NOTE: For Primary Control "Pump Priming Cycle" details, see Paragraph I, No. 2., Step a., Item ii .

4. Close vent fitting and burner flame should start immediately after prepurge is completed. Prepurge prevents burner flame until 15 seconds has elapsed after initial power is applied to burner. During prepurge the motor and igniter will operate but the oil valve will remain closed. Refer to Oil Primary Control Instructions for more details.
