For protection, take preventive actions such as having a security system installed that operates during power outages, senses low temperature and initiates an effective action.
Section: Inspect/Prepare Installation Site Special Requirements ○ ○ ○ ○ THE INSTALLATION OF A BURNER SHALL BE IN ACCORDANCE WITH THE REGULATIONS OF AUTHORITIES HAVING JURISDICTION. For recommended installation practices in the U.S. refer to the latest edition of NFPA 31. (CSA-B139 and CSA-B140 in Canada. Concealed damage — If you discover damage to the burner or controls during unpacking, notify the carrier at once and file the appropriate claim.
Section: Inspect/Prepare Installation Site Figure 2 - Chimney Design - Above the Roof NOTE: Correct chimney design is shown by dotted lines. Incorrect chimney design, as shown by the solid lines, may result in down-drafts. Minimum Clearence: 2 FT. Inspect chimney or direct vent system 1. Starting with minimum gph firing rate, the minimum size recommended is 6” flue pipe with 8” X 8” inside chimney, unless specified otherwise by the appliance manufacturer. 2.
Section: Prepare the Burner Exhaust fans and other air-using devices Size air openings large enough to allow for all airusing devices in addition to the minimum area required for combustion air. If there is any possibility of the equipment room developing negative pressure (because of exhaust fans or clothes dryers, for example), either pipe combustion air directly to the burner or provide a sealed enclosure for the burner and supply it with its own combustion air supply.

Section: Wire Burner Fuel supply below the level of the burner – When the fuel supply is more than eight feet below the level of the burner, a two-pipe fuel supply system is required. Depending on the fuel line diameter and horizontal and vertical length, the installation may also require a two-stage pump. Consult the fuel unit manufacturer’s literature for lift and vacuum capability.
Section: Burner Controls Burner Controls Wiring GeniSys Model 7505 Control Explosion, Fire, Scald, and Burn Hazard All heating appliances must have HIGH LIMIT protection to interrupt electrical power and shutdown the burner if operating or safety controls fail and cause a runaway condition. Fire or Explosion Hazard Can cause severe injury, death, or property damage. y The control can malfunction if it gets wet, leading to accumulation of oil or explosive oil vapors.

The burner is idle, waiting for a call for heat. When a call for heat is initiated, there is a 310 second delay while the control performs a safe start check. 2. VALVE-ON DELAY. The ignition and motor are turned on for a 15 second valve-on delay. 3. TRIAL FOR IGNITION (TFI). The fuel valve is opened.
Section: Start-up Burner/Set Combustion Wire Burner partially open air shutter. This is an initial air setting for the pump bleeding procedure only. Additional adjustments must be made with instruments to prevent smoke and carbon monoxide generation. Some Thermostats Are Polarity Sensitive. Reversed polarity could cause erratic cycling of the burner control. Connect the wire from the RH or R terminal on the thermostat to the TR terminal on the control.
Section: Start-up Burner/Set Combustion ○ ○ ○ 2. After flame is established and the burner igniter turns off, close the hand valve in the oil supply line. enters Hard (restricted) Lockout in order to limit accumulation of unburned oil in the combustion chamber. To reset, hold the button down for 15 seconds until the red light turns off and the yellow light turns on. Always verify the control functions according to all specifications before leaving the installation site.
Section: Perform Regular Maintenance Step 4: Recheck smoke level. It should be Zero. -This procedure provides a margin of reserve air to accommodate variable conditions. -If the draft level has changed, recheck the smoke and CO2 levels and readjust the burner, if necessary 4. Once combustion is set, tighten all fasteners on air band, air shutter and escutcheon plate. 5. Start and stop the burner several times to ensure satisfactory operation.
