In order to insure long product life, oxygen sources should be eliminated. This can be accomplished by taking the following measures: 1. Repairing system leaks to eliminate the need for addition of make-up water. 2. Eliminating open tanks from the system. 3. Eliminating and/or repairing fittings which allow oxygen absorption. TS-O-62-B 4. Use of non-permeable materials in the distribution system. 5. Isolating the boiler from the system water by installing a heat exchanger. F.

TS-39- -C Rev. O Fig. 19: Wiring Diagram for Steam Boilers with Optional McDonnell & Miller PS-804-120 Probe LWCO, Beckett AFG Burner and Controls, with or without Tankless Heater NOTE: The McDonnell Miller low water cut off incorporates a 10 second delay to prevent nuisance burner cut-off due to rapid water level fluctuations. The LWCO also has a time delay of 15 seconds which allows additional fill time after water touches the probe. Red LED indicates a low water condition. Fig.
Fig. 21: Wiring Diagram for Water Boilers with Beckett AFG Burner and Controls, without Tankless Heater SEQUENCE OF OPERATION A call for heat by the thermostat energizes the L8148A control which in turn energizes the R4184D primary control to turn on the burner. If burner ignites within approximately 45 seconds and the cad cell sees flame, the burner will continue to operate until the call for heat is satisfied or the setting of the high limit is reached.
SECTION IV: OPERATING AND SERVICE INSTRUCTIONS 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.
NOTICE Burner-specific references in the follow ing instructions pertain to the Beckett AFG , supplied as standard equipment.

TURN “OFF” BURNER and remove pressure gauge. Install gauge port plug and tighten. Start burner again. 6. CAD CELL LOCATION AND SERVICE The burner is supplied with a cadmium sulfide flame detector mounted at the factory, mounted on the bottom of the ignitor. See Figure 25.
CAD CELL TEST g. Open line switch. Clean cell face and see that cell is securely in socket. Reconnect leads. Reset safety switch. h. Close line switch. If burner starts and runs beyond safety switch cut-out time, cell is good. If not, install new cell. K. CHECK FOR CLEAN CUT OFF OF BURNER. 3. WARNING — Check High Limit Control — Jumper Thermostat Terminals. Allow burner to operate until shut-down by limit. Installation is not considered complete until this check has been made. 1.
d. Dismount the low water cutoff control from the probe. required. Examine all visible wiring for brittle or worn insulation and make sure electrical contacts are clean and that they function properly. Give special attention to solder joints on bellows and float when this type of control is used. Check float for evidence of collapse and check mercury bulb (where applicable) for mercury separation or discoloration. Do not attempt to repair mechanisms in the field.
v. Continue this slow boiling and trickle of overflow for several hours until the water coming from the overflow is clear. iv. Stop burner and drain boiler in a manner and to a location that hot water can be discharged with safety. v. Refill boiler to normal water line. If water in gauge glass does not appear to be clear, repeat steps (i. thru iii.) and boil out the boiler for a longer time. b.
recommended boil out compound. and can vary from sample to sample. For all of those reasons a spare nozzle is a desirable item for a serviceman to have. iii. Replace safety relief valve. iv. Fill the entire system with water. v. 2. FLAME SHAPE — Looking into the combustion chamber through the observation door, the flame should appear straight with no sparklers rolling up toward the crown of the chamber.
clean water to prescribed water level. IMPORTANT 4. Always keep the manual fuel supply valve shut off if the burner is shut down for an extended period of time. SUCTION LINE LEAKS - THE OIL MUST BE FREE OF AIR. Try bleeding the pump through a clear tube. There must be no froth visible. There are various test kits available to enable you to look at the oil through clear tubing adapted to the supply line at the pump fitting. Air eliminators are on the market that have potential.
(Non-Burnham Drawing Copy from other Manual) AQUASTAT SWITCHING ACTION WITHIN L8124C CONTROL The switching action within the L8124C control has three settings: 1. high limit 2. low limit 3. adjustable differential EXAMPLE: Set point of 140°F; differential set at 25°F. On a temperature rise, R-B will break and R-W will make at 155°F. On a temperature fall, R-B will make and R-W will break at 130°F. Set low limit indicator at the minimum temperature recommended for domestic hot water supply.
smokepipe, burner mounting plate, burner swing door and all flue plates are secured in place. 1. Install the canopy taking care to align the gaskets without blocking the flueways. If gasket is damaged, replace as needed. 2. Reinstall flue plates, making sure gasket on each plate is in place and forms gas tight seal. If damaged replace as needed. 3. Reinstall jacket top panel and secure with sheet metal screws. Replace jacket upper right side access panel. 4.
