The minimum installation clearances are listed in Table 1.
installation, the dampers or air controlling means must prevent chilled air from entering the furnace. If the dampers are manually operated, there must be a means of control to prevent the operation of either system unless the dampers are in the full heat or full cool position. The air heated by the furnace shall not pass through a refrigeration unit unless the unit is specifically approved for such service.

transformers may be powered from the electronic fan timer board where provisions have been made for connections, but should have their own controls. Do not use the direct drive motor connections as a power source, since there is a high risk of damaging the accessories by exposure to high voltage from the autogenerating windings of the direct drive motor. burner nozzle smaller than 0.65 U.S. Gallons Per Hour, install an additional 7 to 10 micron filter as close as possible to the oil burner. 14.
NOTE: Beckett AF Series Burner electrode specifications have been revised. They should be adjusted to be 5/16” above the nozzle centerline. lack block ends on the trunk ducts. These systems may require modification to provide some resistance to the airflow to prevent over-amping of the direct drive blower motor. Selecting a lower blower speed may correct this problem. Direct drive blower speeds are adjusted by changing the "hot" wires to the motor winding connections.
pipe and fittings. The barometric damper should open and close freely. 20. MAINTENANCE AND SERVICE Routine Maintenance By Home Owner All electrical connections should be checked to ensure tight connections. Safety controls such as the high limit controls should be tested for functionality. The fan control should be checked to ensure that the fan on and off delay function continues to start and stop the blower fan at the optimal settings.
After three or four minutes of burner operation, the limit control should turn the burner off. When the limit function test is complete, shut off electrical power to the furnace, replace the neutral wire to the blower fan motor, and then restore power. The blower fan will start up immediately. Once the temperature has dropped and the limit control has reset, the fan will operate until the fan off time is achieved. The oil burner will then resume operation and continue until the thermostat is satisfied.
Appendix A- HML-C AND HMLV-C HML-C and HMLV-C furnaces may be used with the following oil burners. Please note: The Beckett AF, and Riello 40F oil burners are for applications using indoor air for combustion only. For sidewall venting applications utilizing outdoor air for combustion, use the Beckett AFII or the Riello 40BF (Balanced Flue) oil burners only.

the heat anticipator. Set the heat anticipator to the amperage measured. OPERATION OF OIL BURNER Once the furnace flue pipe, electrical and oil line connections have been made, use the following instructions to set the burner: NOTE: THE FURNACE SHOULD BE RUN THROUGH AT LEAST THREE FULL CYCLES BEFORE LEAVING THE INSTALLATION, TO ENSURE THAT ALL CONTROLS ARE OPERATING PROPERLY AND AS EXPECTED. Shut off the electrical power to the furnace. Install an oil pressure gauge to the pressure port on the oil pump.
APPENDIX C OIL PRIMARY CONTROL DETAILED SEQUENCE OF OPERATION Power is applied to unit. The oil primary control completes a self-diagnostic procedure. If no light or flame is present, and unit passes its self-diagnostic procedure, the control enters into the idle mode. Thermostat calls for heat: A) Safety check is made for flame (4 second delay). 1) If flame is not present, the oil primary control will apply power to the burner motor and igniter.

TROUBLESHOOTING OIL PRIMARY CONTROL LED DIAGNOSTIC LIGHT IMPORTANT: Due to the potential hazard of line voltage, only a trained, experienced service technician should perform the troubleshooting procedure. The LED diagnostic light has several functions. It indicates the state or mode in which the oil burner is operating. It will also indicate fault conditions, and help determine cad cell resistance while the burner is operating.
PRELIMINARY CHECKS: Make sure that limit switches are closed and those contacts are clean. ELECTRICAL SHOCK HAZARD. TROUBLESHOOTING IS DONE WITH THE SYSTEM POWERED. BE CAREFUL TO OBSERVE ALL NECESSARY PRECAUTIONS TO PREVENT ELECTRICAL SHOCK OR EQUIPMENT DAMAGE. Check for line voltage power on the oil primary control black and white lead wires. Refer to Table C-4 or C-5 for further troubleshooting information.
Table C-3: Oil Primary Control Troubleshooting continued from previous page Procedure 4. Shield cad cell from external light. 5. Jumper thermostat (T -T) terminals on oil primary control IMPORTANT First remove one thermostat lead wire. Status Indicator light turns off. Corrective Action Eliminate external light source or permanently shield cad cell. Replace cad cell with new cad cell and recheck. If indicator light does not turn off, remove cad cell lead wires from oil primary control and recheck.
Table C-3: Oil Primary Control Troubleshooting continued. Procedure Status Corrective Action Indicator light is on. Remount control onto burner housing. Go to step 6. 10. Check cad cell. Disconnect line voltage power and open line switch. Remove existing cad cell and replace with new cad cell. Disconnect all wires from thermostat terminals to ensure Indicator light is off. Go to step 11. that there is no call for heat. Reconnect line voltage power and close line switch.
Table C-4: System and General Troubleshooting continued Problem Furnace will not start. Possible Cause Photo Cell wiring shorted or room light leaking into photo cell compartment Open safety switch. No fuel oil. Clogged nozzle. Furnace will not start without first pushing oil primary control reset button. (Happens on frequent basis) Clogged oil filter. Low oil pump pressure. Air getting into fuel oil lines, or fuel oil line dirty, clogged, or in some manner defective. Defective burner motor.
Table C-4: System and General Troubleshooting continued Problem Possible Cause System temperature rise too high. Poor “fan off” delay timing selection, (fan stops too soon). Excessive fuel oil consumption. Fuel oil leak. Check fuel oil line for leaks. Repair or replace if necessary. Stack temperature too high. Check stack temperature. Stack temperatures will normally range from 350° to 450°F. Check draft regulator. Draft should be set to -0.02 in. w.c.
Table C-4: System and General Troubleshooting continued Problem Supply air temperature too hot. Supply air temperature too cool. Supply air temperature too cool during first moments of furnace cycle. Possible Cause Airflow blocked or dirty air filter. Insufficient airflow. Excess airflow. Excessive duct losses. Fan control "fan on" setting too low. Excessive duct losses. Remedy Clean or replace air filter. Check all dampers. Open closed dampers including registers in unused rooms.
