Section 2 - Systems & Controls Room Thermostat: The room thermostat automatically controls the on/off operation of the heater according to the setting of the desired room temperature. The thermostat works in conjunction with the oil primary safety control. Oil Primary Safety Control/Flame Sensor: The oil primary control is mounted on top of the burner’s electrical box.
Section 2 - Systems & Controls Electric Air-Solenoid Valve The electric air-solenoid valve is controlled by the oil primary control. It acts as a shut-off valve, (it’s open during operation, and closed when the burner is off ). The electric air -solenoid valve is located inside the burner’s electrical box. Air Operated Fuel Valve The air-operated fuel valve controls fuel flow out of the nozzle.

Section 4 - Chimney/Vent System ! Failure to provide proper venting of the heater exhaust gases could result in death, serious injury, and/or property damage. FOLLOW CHIMNEY MANUFACTURERS INSTRUCTIONS. General Requirements 1. Safe operation of any gravity vented heating appliance requires a proper air make-up system to prevent the heater exhaust gases from being drawn into the building. These gases could cause death, serious injury, and/or property damage.
Section 4 - Chimney/Vent System General Requirements (cont.) 10. Do not install heat re-claimers, manual draft controls, or any other type of restrictive control(s) in the chimney. 11. Install clean out tee with a cap, at the transition of the chimney. FOLLOW CHIMNEY MANUFACTURERS INSTRUCTIONS. 12. Use “Class A” insulated chimney pipe to vent exhaust gases through wall, ceilings, attics, roofs, combustibles, etc. Class A chimney must be used for the entire run once passing through a wall or ceiling. 13.
Section 4 - Chimney/Vent System Alternate Chimney Configurations Some installation configurations may require orienting the chimney flue through the exterior wall, rather than the roof, or utilizing the top exhaust port of the heater, rather than the side port. Please consult with Lanair for guidance in these cases. 1 It is always preferable to install the chimney flue through the roof in order to ensure proper draft and minimize horizontal connectors that can collect debris and moisture.
Section 4 - Chimney/Vent System Barometric Damper The barometric damper balances the draft through the combustion chamber and allows for adjustments. It can be installed in various chimney orientations, but ensure that the barometric damper is installed with the pivot hinge parallel to the ground with the attached weight closing the door when no draft is present.
Section 5 - Fuel Supply Tank Installation General Requirements • The fuel supply tank and supply lines must be installed in accordance with the National Fire Protection Association requirements, as well as State and Local ordinances. • Check state and local codes. In many areas, regulations require oil storage tanks located inside not to exceed 275 gallons individually, and are not to exceed a total capacity of 550 gallons in one building.

Section 5 - Fuel Supply Tank Installation Bypass-Regulator Pump Installation The oil-pressure bypass regulator pump maintains consistent fuel pressure to the burner and returns excess fuel / fuel pressure to the tank. The regulator controls the amount of oil being supplied to the burner and allows for adjustments.
Section 5 - Fuel Supply Tank Installation Metering Pump Installation A metering pump will slowly supply the pricise amount of fuel for your heater model. This minimizes the need for flame adjustments and allows for pumping over longer distances (up to 100 ft.), when necessary.
Section 6 - Fuel Supply Pump/Piping General Requirements 1. Mount the fuel supply pump in a horizontal position (shaft horizontal) near the fuel supply tank. 2. The standard oil pump has a maximum suction lift of 14 feet (6 feet for a metering pump). Suction lift is the length of pipe run from the bottom of the pick-up strainer to the fuel supply pump. Tall tanks and/or cold fuel may require additional fuel-delivery equipment to properly supply the heating system. 3.
Section 6 - Fuel Supply Pump/Piping 12. Do not allow the fuel level in the tank to cover the outlet of the return line. 13. When using a bypass regulator install the fuel supply line from the fuel bypass regulator (port B) to the inlet port on the left side of the burner using 1/2” inside diameter (.493) steel pipe, or 1/2” outside diameter copper tubing. The maximum distance of this line is 25 feet. The fuel supply line must be run below the burner at all times.
Section 7 - Air Supply Installation General Requirements 1. The air supply source must be capable of producing 2.0 CFM @ 30 PSI. 2. Install a shut off valve in the air supply line for service. 3. Install a primary air filter/regulator with a gauge (capable of reading line pressure) in the air supply line prior to the air filter/regulator mounted on the furnace. The primary air filter/regulator is not supplied with the furnace. 4.
Section 8 - Electrical Connections WARNING: HAZARD OF ELECTRICAL SHOCK! Main Electrical Installation 1. All wiring must comply with the National Electrical Code, state and local ordinances, and be wired by a qualified electrician. 2. Electrical service MUST be connected to a separate 20 AMP, 115 VAC, 60 HZ single phase circuit.

Section 8 - Electrical Connections WARNING: HAZARD OF ELECTRICAL SHOCK! Fuel Supply Pump Electrical Installation 1. All wiring must comply with the National Electrical Code, State and Local Ordinances, and be wired by a qualified electrician. 2. The electrical conductors to the fuel pump motor MUST be stranded 14 GA minimum. 3. The electrical service connections for the fuel pump motor are made in the electrical junction box on the side of the heater. 4.
Section 9 - Priming The Fuel Pump Priming The Fuel Pump 1. The fuel level in the supply tank must be above the check valve on the pick-up tube 2. Remove the cap from the fill pipe at the suction line strainer, and fill with clean used oil. Securely replace the fill-pipe cap. 3. When using the bypass regulator, back the thumb screw out (CCW) on the bypass regulator until it is free, then turn (CW) two turns to seat the diaphragm. 4.
Section 10 - Burner Startup Procedure Waste Oil Burner Start-Up 1. Make sure the main electrical service for the heater is turned off, and locked out. 2. Check for proper draft in the chimney. Confirm that there is no positive-draft pressure (air coming DOWN the chimney, usually caused by roof-vent exhaust fans). 3. Make sure there is air pressure at the heater’s air filter/regulator, set at 20 PSI (idle pressure, 15 PSI while heater is running). Set the primary regulator on the air supply line to 30 PSI.
Section 10 - Burner Startup Procedure 11. When using the bypass regulator, adjust the fuel pressure and monitor the gauge on the left side of the burner. Refer to the following table for recommended settings: Oil-Pressure Bypass Regulator Initial Settings Model No. 2 Fuel Oil Approved Waste Oil XT-150 0.5 - 1.0 PSI 1.0 - 1.5 PSI XT(D)-200 1.5 - 2.0 PSI 2.0 - 2.5 PSI XT-250 2.5 - 3.0 PSI 3.0 - 3.5 PSI XT(D)-300 3.0 - 3.5 PSI 3.5 - 4.
Section 11 - Flame Adjustment Flame Adjustment 1. Start the heater, let it run for at least 15 minutes to reach operating temperature before proceeding. 2. Check the chimney draft, set the barometric damper to -0.05 WC when hot and running. 3. Check the atomizing air pressure, set the air filter/regulator on the heater: XT-150, XT(D)-200 = 12-15 PSI XT-250, XT(D)-300 = 15-18 PSI 4.
Section 11 - Flame Adjustment NOTE: ALWAYS WEAR EYE, FACE AND BREATHING PROTECTION AND PROTECTIVE CLOTHING WHEN INSPECTING OR ADJUSTING FLAME. Lift the inspection port cover on the front of the combustion chamber to observe the flame. The flame tips should extend 3/4 of the way into the combustion chamber. When the unit is adjusted properly the ash inside the chamber will be white to off white. Flame Adjustment - Visual Flame is over-fired • Dark yellow, to orange in color.
