The boiler should be located as close to the chimney as possible. The boiler must be properly leveled on a suitable floor. INSTALLATION OF CASINGS The procedure of the installation of the casings is as follows - Do the sides first, then back, front and the top last. FUEL TANK SUPPLY The supply tank and fuel lines must be installed in accordance with all local codes and regulations having jurisdiction in your area. COMBUSTION AIR To achieve satisfactory combustion an adequate supply of fresh air is required. In confined areas grilled openings must be provided. The minimum total area of openings is 1 square foot per gallon of oil burnt per hour. When more than one appliance is in a room additional consideration must be given. CHIMNEY Connect the boiler to a (approved for oil burning equipment) factory built chimney or a masonry chimney equipped with a stainless steel or clay tile liner. The chimney must be capable of maintaining a negative updraft at all times and under all conditions. The OB1000 may be installed with L Type venting. The specification of the chimney to be used complies with the requirement that, other than solid-fuel/oil combinations and approved addons, an oil burning appliance shall not be connected to a venting system serving an appliance vented by another type of fuel. Secure all flue pipes with sheet-metal screws. DO NOT install hand dampers on this unit. Use an approved barometric damper to control draft through the unit. Setting is -0.25" W.C. Flue pipes must have a minimum ½" rise per foot between the boiler and the flue. Never run the flue pipe downhill from the boiler. OIL BURNER INSTALLATION Verify that the nozzle supplied is the proper one for your installation. To install the burner, first put the gasket against the flange on the front of the burner, then through the hole on the lower front of the unit and secure with the (3) - x 16 nuts provided. SEE THE LABEL ON THE BOILER FOR THE INSTALLATION INSERTION. AN IMPORTANT FEATURE OF THE OIL BURNER SETUP IS THAT INSERTION IS CORRECT BEFORE INSTALLATION. ALL BURNERS All burners are supplied with single pipe setup. To change to two pipe system, install the bypass screw using instructions on pamphlet attached to the oil line of the nozzle assembly on the burner. COMBUSTION SET UP All burners are designed to be setup with a No. 1 or No. 0 Bacharach smoke spot. Run the unit for approximately 10 minutes before testing is done, as this will give the flame time to stabilize. On Riello burners the turbulator should be set according to this manual and the label on the front of the unit and only the air shutter should require additional adjustment. On Beckett burners make sure the appropriate "pin" is installed for the nozzle being used. BLOCKED FLUE SENSOR On OB1000 & OB2000 boilers that do not use a balanced flue system or a power venter a Field Controls WMO-1 sensor is installed in the flue as given in the sensor installation instructions. The blocked flue sensor is designed to shut off the burner in the event that the flue has become blocked. When this has happened the burner can not be started again until the sensor has been reset. Pushing in the red button, which is accessed through the hole in the front of the sensor, resets the sensor. CAUTION: Only try this once and then call a qualified service technician. BALANCED FLUE The OB1000 boiler is certified to be installed with the "Benjamin Balance Flue Venting System" using the Riello BF3 or BF5 oil burners. Please see the instruction manual (included with the balance flue terminal) for proper installation procedures. POWER VENTING The OB1000 and OB2000 oil fired boilers are certified to be installed with the Tjernlund SS1C Power Venter. They are certified for this installation with the Riello burner only. Please see instruction manual included with the SS1C for necessary installation instructions and clearances. NOTE: The power venter limits the output to 271,000 BTU. Therefore the maximum nozzle size for the Riello F10 burner on the OB2000 would be 2.00 x 60 degree. CAUTION TO HOMEOWNERS Do not push the reset button on the burner or the blocked flue sensor more than once to restart the burner. If the flame fails to establish or stabilize call a heating technician. This is a safety feature and means there is something wrong with the burner or venting system. DO NOT TAMPER WITH THE UNIT OR CONTROLS - CALL A QUALIFIED SERVICE TECHNICIAN. BOILER MAINTENANCE As soot is a non-conductor of heat it is important to have the boiler and flue pipes cleaned at least once a year. It is recommended that this be done at the end of each heating season, at a minimum. This is to be done by a qualified heating technician, and any service requirements should be fulfilled at the same time. Cleaning of the boiler tubes requires a 2" boiler tube brush which is available from most furnace & boiler retailers. To clean the boilers use the following: 1. Make sure the power to the boiler is shut off and the fuel line valve is closed. 2. Remove the smoke pipe from the boiler. 3. Remove the top casing surrounding the smoke pipe. 4. Remove two wing nuts and the smoke collector box. 5. Remove the burner. 6. Lift out the turbulators in the fire tubes. 7. Brush soot down into the combustion area. 8. Vacuum the soot through the burner opening. Note: At this time inspect all interior passages. All combustion areas should be cleaned and any undue corrosion should be brought to the attention of the appropriate people. 9. To reconstruct, reverse order of directions. NOTE: The pressure relief valve should be checked monthly to ensure safe operation. This is done by momentarily opening the relief valve. Ensure relief valve is piped to a drain to prevent hot water escaping from coming in contact with anyone. TO START THE BURNER 1. See that all valves in the oil lines are open. 2. With the main cutout switch for the oil burner electrical circuit in the "OFF" position, set the thermostat at a point above room temperature. 3. Set the electric switch to the "ON" position. If the burner fails to start instantly set the master switch to the "OFF" position and call a qualified service technician. 4. If the burner starts to operate normally leave the switch "ON" and reset the thermostat to the desired temperature. Never start the burner under the following conditions: 1. WHEN EXCESS OIL HAS ACCUMULATED. 2. WHEN OIL VAPORS ARE PRESENT. 3. WHEN THE COMBUSTION AREA IS VERY HOT. 4. WHEN THE CLEAN OUT COVERS ARE NOT SECURE. 5. When the smoke pipe is removed or blocked. 6. Any situation that would lead to an unsafe condition. Never push the reset on the burner more than once; contact a heating technician. TO STOP THE BURNER 1. Set the main cutout to the "OFF" position. 2. Set the thermostat as far below room temperature as possible. IF THE BURNER FAILS TO OPERATE Call a qualified service technician. The trouble may be due to: 1. Blown fuses in the electrical circuit. 2. The thermostat may be set below room temperature. 3. The combustion control may require "resetting". 4. The oil valve may be closed. 5. The oil supply may be too low. 6. The blocked flue sensor may be tripped. TO STOP THE BURNER FOR AN EXTENDED PERIOD OF TIME 1. The main cutout switch should be set to the "OFF" position. 2. SHUT OFF THE MANUAL OIL VALVE TO THE BURNER. 3. The burner should be covered to protect it from dust and dampness. 4. The heating system should be checked and cleaned if necessary by a Qualified Service Technician. TO START THE BURNER AFTER AN EXTENDED SHUTDOWN 1. The strainer in the pump should be cleaned and if a filter is installed in the oil line it should be cleaned and the filter cartridge replaced. 2. The ignition points should be checked and the nozzle cleaned & replaced. 3. Oil motor (see LUBRICATION) 4. Start the burner by following the instructions under paragraph "TO START THE BURNER". 5. It is recommended that a qualified service technician be called to clean the unit and burner and make sure that the burner is operating properly. The installer should identify the emergency shut off switch and valves. WHEN THE BURNER IS IN OPERATION 1. Check flame periodically, if it becomes out of shape or smoky, call a qualified service technician. 2. When cleaning the furnace room or utility room always stop the burner to reduce the amount of dust and lint drawn into the burner. 3. The electric ignition system and all controls should be checked periodically for reliability of operation and adjusted if necessary. OIL BURNER The oil burner should be removed at least once each heating season, cleaned and serviced. Also inspect and clean any accumulated soot and debris from the combustion chamber and transfer duct. Inspect and replace the burner gasket if necessary. To be performed by a Qualified Service Technician. OIL FILTER The cartridge should be replaced at least once a year. The filter body should be thoroughly cleaned before installing a new cartridge. TO CLEAN THE STRAINER 1. Oil valves between the tank and the burner should be closed. 2. The strainer cover should be removed. 3. The strainer basket should be taken out and washed with kerosene. 4. The strainer basket and covers should be reassembled with gaskets that are clean and in good condition. 1BURNER SPECIFICATION NOZZLES: A, W & B are Delevan FUEL: Use No. 2 Furnace Oil RIELLO BURNERS Burner Insertion - F5, BF3 & BF5 = 3-1/8"; F3 & F10 = 3-1/2" MODEL R105 R120 R150 R180 INPUT SERIES US GPH 1000 1000 1000 1000 0.85 1.00 1.25 1.50 NOZZLE SIZE PUMP RIELLO PSIG MODEL 0.75 60° A 130 F3 0.85 60° W 140 F5 1.00 60° W 155 F5 1.25 60° W 145 F5 SETTINGS TBL AIR (INITIAL) 0.5 7.8 1.0 3.2 2.0 5.6 3.0 8.0 OUTPUT BTU 102,000 120,000 147,000 176,000 BF3-85 BF3-100 BF5-120 BF5-150 1000 1000 1000 1000 0.75 0.65 80° W 130 BF3 0.89 0.75 80° W 140 BF3 1.00 0.85 60° W 145 BF5 1.25 1.10 60° W 135 BF5 1.5 5.5 3.0 5.8 2.0 4.5 3.0 6.0 91,400 108,700 121,500 153,600 R215 R250 R275 R330 2000 2000 2000 2000 1.75 1.50 60° A 135 F10 2.00 1.75 60° A 130 F10 2.25 2.00 60° A 125 F10 2.80 2.25 60° A 155 F10 0.0 4.0 1.0 5.0 2.0 6.0 4.5 8.0 213,000 243,000 271,000 328,000 BECKETT BURNERS Burner Insertion: 2-3/4" MODEL INPUT SERIES US GPH NOZZLE SIZE PUMP BECKETT PSIG AF II SETTINGS PIN# AIR (INITIAL) B90 B107 B120 B150 B180 1000 1000 1000 1000 1000 0.75 0.65 70° A 140 85-HLX50HD 4 7.0 0.89 0.75 70° A 140 85-HLX50HD 5 7.5 1.00 0.85 60° B 140 150-HLX50HC 0 4.0 1.18 1.00 60° B 140 150-HLX50HC 5 4.5 1.50 1.25 70° B 140 150-HLX50HC 8 5.0 OUTPUT BTU 90,000 107,000 120,000 140,000 174,000 NOTE: Models 105, 120, 150, 180, 215, 250 are Energy-Star compliant.
