• INOV8 F240, INOV8 Model F240 – Edited September 2008 33 SECTION 5 –DETAILED SERVICING PROCEDURES In the course of servicing your burner, you may be required to perform or be knowledgeable of the following procedures. Refer to the glossary. REMOVING THE MODULE FROM THE BURNER 1. Shut the burner off. 2. Pull the 6-prong plug. 3. Remove screws from front lip of transformer. Tip the ignition transformer back on its hinge. 4. Move the UV sensor out of the way. Take note of its position as it must be returned to exactly the sam

• INOV8 F240, INOV8 Model F240 – Edited September 2008 35 3. Assuming you’ve ruled out the filters, there is possibly an air leak or blockage in the oil supply line. Install a test hose to the pump inlet and suck from a bucket of oil on the floor. Then see if you can get good oil flow. If you do, there is an air leak or obstruction in the line coming form the oil tank. (Or you’re out of oil.) 4. If you still get no flow, squirt some oil into the oil inlet in the pump and try again – the pump may have just needed priming. Try screwing the oil pressure adjusting screw all the way

• INOV8 F240, INOV8 Model F240 – Edited September 2008 17 Installation Instructions 1. It’s generally a good idea to locate the bench tank on an outside wall for ease in venting the tank and venting the flue gases of the furnace. 2. Attach the upright support brackets to the back of the tank by sliding them into the square tube receptacles having the support brackets. Use two 3/8" bolts per support bracket to secure. 3. Secure the furnace to the top of the support brackets. Secure to the support brackets with the four bolts provided. If left undone may result in the furnace falling. 4. There are four openings on top of the tank, to be used

The OUT2 set point (Interlock) of the oil temperature controller has been programmed too low. b. Draft is insufficient until the chimney warms up 8. The unit fires and runs well for a short time. Then abruptly shuts off, re-fires, runs, shuts off, etc. a. The oil temperature is falling below the OUT2 (Interlock) set point in the oil temperature con

• INOV8 Model F240 – Edited September 2008 11 10. Install the provided sheet metal air boot onto the extended casing of the burner. The provided sponge rubber gasket will seal the boot to the burner casing. The two slots in the gasket will line up with the two oil pump bolt holes. (Rotate the air boot until the left side is essentially vertical.)

• INOV8 F240, INOV8 Model F240 – Edited September 2008 16 BENCH TANK INSTALLATION Tanks are available in a variety of sizes and configurations. Our model T300 HB, a 300 gallon tank with steel supports, holds the INOV8 furnace eight feet above the floor. Installations using this bench tank are easier than those without a bench tank because of the ease in mounting the furnace versus hanging and the short distance for running the oil supply line. The bench tank comes fully supplied with all necessary fittings for a complete installation. Many states and cities have additional regulations regarding the storage of waste or other fuels that

• INOV8 F240, INOV8 Model F240 – Edited September 2008 51 SECTION 6 - GLOSSARY Air Apportioning Adjustment A setscrew adjustment in the module block which reduces the 30-psi atomizing air coming in to the correct pressure at the nozzle. It is factory set and held with Loctite. Air Regulator The air hose connects to this. It regulates the primary air for combustion. It is located on the right side of the burner. Used to reduce the high air pressure from your compressor to the 30 psi atomizing air pressure requ

• INOV8 F240, INOV8 Model F240 – Edited September 2008 40 Oil Temperature & Pressure Settings The INOV8 burner has been tested to burn fuel oils up to #6, and a variety of used petroleum based shop and vehicle oils. Testing has also been done on a variety of vegetable based oils, such as corn, soybean, and canola oils – both used and new. All of these oils make potential fuels but have different BTU values and flashpoints that require adjustments to the burner pressure and preheat temperature. It’s also important to be aware that the preheat temperature showing on th

C EILING MOUNT INSTALLATION CONSIDERATIONS Be aware that the F240 furnace weighs 500 pounds (186 kg) and the F240 SC weighs 550 pounds (205 kg) when planning its installation. Before suspending the unit, check the supporting structure to ensure it has sufficient load-carrying capacity. The furnace comes with 5/8

• INOV8 F240, INOV8 Model F240 – Edited September 2008 43 7. The 120v on the orange wire energizes (opens) the air and oil solenoids. 8. The air now coming into the module will cause: a. The Bimba cylinder to withdraw the needle from the nozzle. b. Air to flow out the nozzle (To atomize the oil stream when it arrives.) 9. The 120v on the orange wire also energizes (opens) the oil solenoid causing it to allow oil to flow to the oil gauge and out the nozzle. 10. The hot atomized oil sprays through the ignition arc, causing it to ignite. This state continues throughout the 10 second PTFI interval – whether a flame w

ELECTRICAL HOOKUP OF THE FURNACE 1. Remove a convenient knock-out from the electrical junction box to allow connection of your electrical supply conduit. 2. Attach the hot wire (typically black) to the 6” black pigtail that comes off the GFCI “Line Hot” terminal. 3. Attach the Neutral

• INOV8 Model F240 – Edited September 2008 38 as the ‘spinner washer’. The oil passes through the small passage in the center of the spinner and that’s where nozzle blockages occur. For cleaning: 1. Pull the module out of the burner to get better access to the nozzle. Refer to the section on Removing the Module from the Burner on page 33. 2. Unscrew the nozzle cap w

At the end of the PRE PURGE cycle which is 90 seconds, the PTFI light comes on. 11. PTFI light ON means the burner is trying to fire. 12. During the period that the PTFI light is on (and thereafter if the burner fires) the air pressure can be corrected to 30 psig if necessary and the oil pressure can be set to produce a flame that falls just short of hitting the far end of the burning chamber. Look through the viewing port. Typical oil pressure is 12 psig. Be aware that oil pressure can be adjusted ONLY when PTFI is on or the burner is

• INOV8 F240, INOV8 Model F240 – Edited September 2008 42 ADDENDUM THEORY OF OPERATION Overview: When the wall thermostat calls for heat, it does so by sending power to the Fireye controller, which then turns on the burner motor and oil heater. The burner motor drives the oil pump which circulates the oil through the module, vapor eliminator and back to the pump to be circulated again. On each pass through the module, the oil gets a little hotter by passing close by the oil heater. Each pass through the vapor eliminator filters it and vents off any vapor th

• INOV8 F240, INOV8 Model F240 – Edited September 2008 8 1. A continuous supply of compressed air (2.0 CFM at 30 psig) is required to operate the furnace. The furnace includes a factory provided pressure regulator rated at 300 PSIG with a gauge rated to 160 PSIG inlet for shop air. The connection requires 1/4 " NPTM. The pressure regulator is located on the right side of the burner housing (see photo on page 7) and controls air for use in atomization. 2. The shop air must be free of dirt and water. A filter should be installed in the line before attaching to the INOV8 burner. Do not attach the shop air directly to the burner module as damage will occur from

The range of temperature for this setting is 100 o F to 140 o F. Note: At least 20 o F span must be between the OUT1 and OUT2 settings for this to function properly. Also be aware that when the preheater switch (see item #24 on the burner diagram for location) is in the OFF or “0” position, the lights on the temperature control will be off. Message Display Under normal operation, the temperature of the probe will be displayed. Call INOV8 if any of the following messages appear: •

• INOV8 F240, INOV8 Model F240 – Edited September 2008 34 push in on the tip of the needle that protrudes from the nozzle. Then let it back out gently and try the procedure again. You should get a stream of oil for 10 seconds. Repeat the procedure three or four times (popping the needle loose each time, if necessary) to insure complete flushing. 9. Perform the Maintenance Procedure: Cleaning the Nozzle. 10. With the spinner replaced and the nozzle back on, put the module back into the burner, turn the air pressure back down to where it was originally and see if the burner fires. 11.
