Installation & Service Manual MPO-IQ 7 Oil Piping A. GENERAL ! 1. Use flexible oil line(s) so the burner swing door can be opened without disconnecting the oil supply piping. 2. A supply line fuel oil filter is recommended as a minimum for all firing rates but a pleated paper fuel oil filter is recommended for the firing rates below 1.0 GPH to prevent nozzle fouling. NOTICE Do not use compression fittings. Oil piping must be absolutely airtight or leaks or loss of prime may result.
MPO-IQ Installation & Service Manual 7 Oil Piping (continued) C. TWO PIPE OIL LINES 1. For two piped systems, where more lift is required, the two-stage fuel unit is recommended. Table 7 (two-stage) and Table 8 (single-stage) show allowable lift and lengths of 3/8 inch and 1/2 inch OD tubing for both suction and return lines. Refer to Figure 30. 2. Follow the oil pump manufacturer’s recommendations on the proper connections for a two pipe system. Some manufacturers require the insertion of a bypass plug.
MPO-IQ Installation & Service Manual 8 System Start-Up ! WARNING All boilers equipped with burner swing door have a potential hazard which can cause severe property damage, personal injury or loss of life if ignored. Before opening swing door, turn off service switch to boiler to prevent accidental firing of burner outside the combustion chamber. Be sure to tighten swing door fastener completely when service is completed.
MPO-IQ Installation & Service Manual 8 System Start-Up (continued) 4. Allow burner to run until oil flows from vent fitting is a SOLID stream without air bubbles for approximately 10 seconds. 3. READJUST THE HEAD SETTING. It might be necessary to move the head forward or back one position at a time to optimize the smoke and CO2 readings. Refer to Burner Manufacturer's Manual for details. NOTE: For Primary Control "Pump Priming Cycle" details, see Paragraph J, No. 1., Step b. 4.
Installation & Service Manual MPO-IQ 8 System Start-Up (continued) ! WARNING Before installation of the boiler is considered complete, the operation of all boiler controls must be checked, particularly the primary control and high limit control. J. VERIFY HONEYWELL OIL PRIMARY FEATURES using procedures outlined in Instructions furnished with control or instructions as follows: 1. R7284 FEATURES AND CONTROLS a. The Oil Primary is a microprocessor-based control.
MPO-IQ Installation & Service Manual 8 System Start-Up (continued) • If safety switch shuts down burner and • • • • • resistance is above 1600 OHMS, open line switch to boiler. Access cad cell under ignitor, clean face of cad cell and see that cell is securely in socket, see Figure 32. Check gasket around perimeter of ignitor lid for proper seal. If gasket is missing or damaged, replace gasket. Room light can effect cad cell resistance. Reset safety switch.
MPO-IQ Installation & Service Manual 8 System Start-Up (continued) Important Product Safety Information: Refractory Ceramic Fiber Product WARNING Some boiler components use materials that contain refractory ceramic fibers (RCF). RCF has been classified as a possible human carcinogen. When exposed to elevated temperatures, RCF may change into crystalline silica, a known carcinogen.
MPO-IQ Installation & Service Manual 9 Operating Figure 33: Boiler Control & Option Panel Orientation A. BOILER SEQUENCE OF OPERATION 1. The boiler's sequence of operation is shown in Table 9. 2. When there is a call for heat the boiler control starts the system circulator and the thermal purge (circulator pre-purge time) begins.
Installation & Service Manual MPO-IQ 9 Operating (continued) burner will stop. When water level is replenished, the burner will restart. 8. On burner start, if the cad cell does not see flame during the trial for ignition, the oil primary control will shut the burner down and enter into a hard lockout. The Oil Primary must be reset manually before the burner can be restarted. B.
MPO-IQ Installation & Service Manual 9 Operating (continued) D. USING THE OPTION PANEL Option Cards are available from distributors and are the simplest way to add functionality, safety and efficiency to your heating system. The Option Panel provides an easy and convenient means to "plug-in" an Auxiliary High Limit, Low Water Cut-off and/or Outdoor Reset function. For operating instructions, refer to the instructions supplied with those cards. E.
Installation & Service Manual MPO-IQ 9 Operating (continued) is started and boiler firing is delayed pre-purge minutes. If the temperature drops below 140°F or there is a DHW Call for Heat the boiler is started without delay. Additionally, the boiler is started without delay if the thermostat call for heat is initiated when the boiler water temperature is less than 140°F. This feature helps save energy by satisfying home heating needs with residual boiler heat rather than cycling the boiler.
Installation & Service Manual MPO-IQ 9 Operating (continued) When an Outdoor Air Reset Option Card is installed and there is a DHW call for heat there is an adjustable DHW Temperature Setpoint and Priority Timer included. Refer to Table 11B. b. When is set equal to Zone Request () When there is no IWH the “ZC” output may be configured to control a second heating zone. This is particularly helpful when the home uses only two heating zones.
Installation & Service Manual MPO-IQ 10 Maintenance and Service Instructions A. MAINTENANCE OF LOW DEVICES (when installed) WATER CUT-OFF See Instructions provided with Low Water Cut-off Option Card for Installation Instructions. ! WARNING Probe type low water cut-off devices require annual inspection and maintenance. 1. PROBE TYPE LOW WATER CUT-OFF Although these devices are solid state in their operation, the probe is exposed to possible contamination in the boiler water and subject to fouling.
Installation & Service Manual MPO-IQ 10 Maintenance and Service Instructions (continued) c. Remove relief valve using extreme care to avoid damaging it. d. Add an appropriate amount of recommended boil out compound. e. Replace relief valve. f. Fill the entire system with water. g. Start firing the boiler. h.

MPO-IQ Installation & Service Manual 11 Boiler Cleaning ! WARNING All boiler cleaning must be completed with burner service switch turned off. Boilers equipped with burner swing door have a potential hazard which can cause severe property damage, personal injury or loss of life if ignored. Before opening swing door, turn off service switch to boiler to prevent accidental firing of burner outside the combustion chamber. Disconnect the burner plug from the receptacle in the front jacket.
MPO-IQ Installation & Service Manual 11 Boiler Cleaning (continued) Figure 35: Cleaning of Boiler Flueways ! WARNING This boiler contains controls which may cause the boiler to shut down and not restart without service. If damage due to frozen pipes is a possibility, the heating system should not be left unattended in cold weather; or appropriate safeguards and alarms should be installed on the heating system to prevent damage if the boiler is inoperative.
MPO-IQ Installation & Service Manual 12 Troubleshooting A. COMBUSTION 1. NOZZLES — Although the nozzle is a relatively inexpensive device, its function is critical to the successful operation of the oil burner. The selection of the nozzle supplied with the MPO-IQ boiler is the result of extensive testing to obtain the best flame shape and efficient combustion. Other brands of the same spray angle and spray pattern may be used but may not perform at the expected level of CO2 and smoke.
MPO-IQ Installation & Service Manual 12 Troubleshooting (continued) c. Defective nozzle causing flame to be erratic. d. Excessive airflow or draft causing flame to leave burner head. e. Excessive back pressure causing flame to be erratic. 3. Control locks out after Trial For Ignition (TFI). a. No oil to burner. b. Shorted electrodes. c. Nozzle clogged. d. Airflow too high. e. Ignitor module defective. f. CAD cell defective. g. Oil valve stuck open or closed.
MPO-IQ Installation & Service Manual 12 Troubleshooting (continued) 4. A defective control or component is generally the least likely cause. Before replacing a component, try to rule out all other possible causes. Possible ErP (External Error) Values: 5. When checking voltage across wiring harness pins be careful not to insert the meter probes into the pins. Doing so may damage the pin, resulting in a loose connection when the harness is reconnected.
