Section 5 - Fuel Supply Tank Installation

If using a Lanair supply tank follow instructions included with the tank.

General Requirements

1. 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.

2. Regulations require oil storage tanks located inside not too exceed 275 gallons individu-

ally,and are not to exceed a total capacity of 550 gallons in one building. Check State and Local codes.

3. Locate the fuel supply tank inside the building as close to the heater as possible. It

should be no further than 25 feet from the heater to avoid oil flow problems.

4. The fuel supply tank must be mounted below the burner and the by-pass regulator (or

supply pump assembly when using the optional metering pump). Mounting the fuel supply tank above the burner will create head pressure and over-fire the burner voiding the warranty.

5. Pitch the fuel supply 2º with the drain valve at the lowest end to drain off water and

sludge. Sludge may have to manually be removed.

6. Some ordinances may require the fuel supply tank to be vented to outside and

above the roofline.Check State and Local codes. Keep the vent clear.

7. Install the fuel tank fill pipe at the end of the tank and above the drain.

8. Label the fuel tank for the recommended fuels.

9. Strain all fuel with a 50 X 50 mesh strainer before putting fuel into the tank.

10. When filling the fuel tank with a motorized pump,never leave unattended to prevent

over filling and/or spillage.

11. Keep cap on the fuel tank when not filling.

For optimum performance, the waste oil pump manufacturer recommends that multi-weight oils such as 5W-30W be maintained at 32˚ F

minimum and straight weight oils such as 40W and 50W be maintained at 50˚ F minimum.

QUESTIONS?... Contact Customer Service at 1-888-370-6531 M-F 8:00 am- 4:15 pm CST

Section 9 - Controls

s 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.

s Oil Primary Safety Control/Cad Cell:

The oil primary control is mounted on top of the burner’s electrical box.When the thermostat calls for heat the oil primary control starts the burner by switching on the air solenoid valve, ignition transformer, combustion air blower, and the fuel pump.The oil primary control works in conjunction with the cadmium sulfide cell (cad cell). The cad cell is mounted inside the burner cover, and faces the flame.The cad cell monitors the light level inside the combustion chamber to insure there is a flame present. If there is a loss of flame the primary control will go into its recycle mode. After 1-2 minutes the primary control will restart the burner.When this happens if there is a flame present, the burner will continue to function. If on start-up no flame is established in 30 seconds the primary control will lock out.

CAUTION: Do not press the reset button more than twice. If the burner fails to start refer to Section 14 - Trouble Shooting. Burner has a (2) minute automatic restart feature.

s Fan/Limit Control

The fan/limit control performs 3 functions. The fan/limit control monitors the temperature of the air inside the cabinet. When the air reaches a set point (usually 120º F) it will switch on the heater fan.When the temperature in the cabinet drops below 90º F the fan/limit control will turn the fan off.The Fan/Limit Control contains the axial fan on manual by-passing its automatic function.

The Fan/Limit Control monitors the temperature of the air inside the cabinet. When the temperature exceeds a fixed set point it switches the burner (Oil Primary Control) off until the temperature drops to a safe level.The burner will then restart.

“CAUTION”This means the heater has reached its “High Limit”, the cause must be determined and corrected before further use (over firing the unit is normally what causes this condition). The Fan/Limit Control is located on the top on the front of the cabinet.

an external slide switch to turn

s Barometric Draft Control

The Barometric Draft Control automatically maintains a pre-set chimney draft, and is located in the chimney connector.

s Air Filter/Regulator

The Air Filter/Regulator performs two functions: It removes condensation and dirt from the air.and it controls the amount of air pressure reaching the nozzle and air operated fuel valve.The Air/Filter Regulator is mounted on the cabinet near the burner.

Visit our website at: www.lanair.com

Section 9 - Controls

s 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 of the burner’s electrical box. (See Page 51).

s Air Operated Fuel Valve

The Air Operated Fuel Valve controls fuel flow out the nozzle.When the Electric Air Solenoid Valve opens and air pressure pushes on the fuel valve diaphragm, the plunger moves off the nozzle seat allowing fuel to enter the nozzle. The Air Operated Fuel Valve is located on the back of the air pre-heater. (See Page 51).

s Air/Oil pre-heater

The Air/Oil pre-heater is an assembly that preheats the atomizing air and fuel to a predetermined temperatu burner (See Page 51).

s Snap Disc

The Snap Disc accurately controls the temperature of the air/oil pre-heater assembly with two resistance type cartridge-heating elements. The Snap Disc is mounted on the oil preheater inside the burner. (See Page 51).

re to properly combust used oil. The Air/Oil pre-heater is located in the

s Nozzle

The Nozzle uses air pressure to help pull fuel through its small orifice, and to atomize the fuel for proper combustion.The Nozzle is located on the end of the air pre-heater opposite the fuel valve. Replace the Nozzle annually, as they are prone to wear by contaminants in waste oil (See Page 47).

s Fuel By-Pass Regulator (This is not used with the Optional metering pump)

The Fuel By-Pass regulator controls the pressure of the fuel to the nozzle. The Fuel By-Pass regulator is located in the line between the outlet side of the pump and the burner.

s Fuel Supply Pump

The Fuel Supply Pump pumps fuel from your oil storage tank to the burner. The Fuel Supply Pump should be located as close to the fuel supply tank as possible. The Fuel Supply Pump must be mounted horizontally (Shaft).

s Optional Metering Pump Assembly

The metering pump pumps fuel from your oil storage tank to the burner. It also controls the volume of fuel, and no regulator is required. The metering pump should be mounted on your fuel supply pump with the shaft in the horizontal position.

CAUTION:TO AVOID BOLT BREAKAGE, DO NOT OVER-TIGHTEN

6. Use an industrial type canister vacuum cleaner with a high efficiency filter, or suitable

tool. Failure to clean heat exchanger tubes annually will impair draft. Reaching through the burner opening, vacuum or shovel the ash from the combustion chamber. Inspect the combustion chamber and target brick. Use care when cleaning the combustion chamber area so the target brick is not disturbed. Insufficient or irregular cleaning intervals will cause inefficiency, random shutdowns, and extreme damage to the combustion chamber.

7. Before replacing the combustion chamber access doors, replace the white gasket seal on

the door (contact the Lanair Service Department).When replacing the gaskets apply a light film of gasket adhesive to adhere the new gasket to the door.Lube the threads of the screws with a high temperature lubricant. Re-install the heat exchanger access panel. If any nuts are stripped, replace (use brass).

8. Replace the inspection port with the two (2) #8 hex head sheet metal screws (if

removed). Re-install the clean out cover. Replace burner.

9. Remove the clean out panel on the front left of unit by removing (4) #8 screws to

expose the manifold clean out port.

10. On the left side facing the front of the unit remove the (4) #10 sheet metal screws from

the manifold clean out port. Using an industrial type canister vacuum cleaner with a high efficiency filter, remove all ash accumulation.

11. The chimney connector can also be removed to allow access to the mani

ing. Clean and inspect the chimney connector if necessary. Replace the four (4) #10 screws in the clean out ports on the heater. Replace the front clean out plate, replacing the ten (4) #8 sheet metal screws. Check your draft reading to make sure your barometric damper is properly set (See Section 4).

12. Remove roof chimney cap and cleanout tee cap. Using a properly sized chimney brush

sweep ash and soot from roof downward until the chimney is completely clean. Reinstall chimney and cleanout tee caps.

Section 14 - Troubleshooting

Initial Diagnosis:

When an operating problem occurs, a determination must be made whether or not the fuel pump is pumping a sucient amount of oil that contains no air or water.

Take these steps:

tAdjust the burner air regulator to -0- PSI. tTurn pre-heater rocker switch o (red light o ). tShut o oil supply line valve to the burner. tRemove the fuel supply line from the supply tank. tWhen using a by-pass regulator attach a exible piece of tubing at least 3 feet long to the

outlet on the return side of the oil by-pass regulator.

tWhen using a metering pump disconnect the fuel supply line from the burner. tInsert the tubing into the bottom of a large jar. tJump the cad cell circuit and start the fuel pump (see below). tAttempt to ll the jar above the open end of the tubing. tIf the pump will not pump fuel, attempt to prime the pump (Section 10). If the pump

won’t prime refer to Flow Chart Item B.

If no air or water is present the ow must be determined:

tWhen using a by-pass regulator pump fuel for 1 minute into a graduated container, if the ow rate is less the 250 MILS/Minute (8-1/2 Ounces), refer to Section 14 Troubleshooting Chart Item B.

If the ow rate is more than 250 MILS/minute (8-1/2 Ounces), refer to Troubleshooting Chart Item C.

When using the optional metering pump:

Pump fuel for 1 minute into a graduated container. The ow rate will vary by model.

MX-150 . . . . . . . . . . . . . . . . . . 66 ML/MIN

MX-200 & MXD-200 . . . . . . 87 ML/MIN

MX-250 & MXB-250 . . . . . . 109 ML/MIN

MX-300 & MXD-300 . . . . . . 139 ML/MIN

If ow rate using a metering pump is more than +/- 10% contact Lanair Service at 888-370-6531.

After repairs are made, remove the cad cell jumper wire, and reconnect the cad cell wires to the oil primary.
