FORCE Installation, Operating & Service Manual 9 Oil Piping ! WARNING 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. 3. Use Flared fittings only. Cast iron fittings cannot be used. NOTICE: Do not use compression fittings.
FORCE Installation, Operating & Service Manual 9 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 31. 2. Follow the oil pump manufacturer’s recommendations on the proper connections for a two pipe system.
FORCE Installation, Operating & Service Manual 10 System Start-Up ! WARNING All boilers equipped with burner swing doors 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.

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.
FORCE Installation, Operating & Service Manual 10 System Start-Up (continued) NOTE: DO NOT remove "T-T" jumper unless wiring diagram indicates a direct connection from thermostat and/or tankless heater HydroStat 3250 control to the oil burner primary control's "T-T" terminal. Refer to appropriate wiring diagram, see Figures 27 and 28. vi.
FORCE Installation, Operating & Service Manual 10 System Start-Up (continued) c. Allow the temperature to drop below control setting. The burner must restart. d. Boiler installation is not considered complete until this check has been made. 5. CHECK LOW WATER CUT-OFF a. Press and hold the test / settings button for 5 seconds. b. The red low water light should illuminate and the burner circuit (B1 & B2) should deenergize. 6.
FORCE Installation, Operating & Service Manual 11 Operating Refer to the HydroStat 3250 Installation Instructions and Operating Manual included with these instructions. IMPORTANT This boiler is equipped with a feature that saves energy by reducing the boiler water temperature as the heating load decreases. This feature is equipped with an override which is provided primarily to permit the use of an external energy management system that serves the same function.
FORCE Installation, Operating & Service Manual 12 Service and Maintenance Instructions A. WATER BOILERS: 1. Filling of boiler and system. GENERAL — In a hot water heating system, the boiler and entire system (other than the expansion tank) must be full of water for satisfactory operation. Water should be added to the system until the boiler pressure gauge registers 12 psi. To insure that the system is full, water should come out of all air vents when opened. 2. BOILING OUT OF BOILER AND SYSTEM.
FORCE Installation, Operating & Service Manual 12 Service and Maintenance Instructions (continued) IMPORTANT IF, DURING NORMAL OPERATION, IT IS NECESSARY TO ADD MORE WATER THAN INDICATED BELOW, CONSULT A QUALIFIED SERVICE TECHNICIAN TO CHECK YOUR SYSTEM FOR LEAKS.

FORCE Installation, Operating & Service Manual 13 Boiler Cleaning ! 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. A. CLEAN THE FLUEWAYS (See Figure 39). 1.
FORCE Installation, Operating & Service Manual 13 Boiler Cleaning (continued) Figure 39: Cleaning of Boiler Flueways ! WARNING The boiler must be connected to an approved chimney in good condition. Serious property damage could result if the boiler is connected to a dirty or inadequate chimney. The interior of the chimney flue must be inspected and cleaned before the start of the heating season and should be inspected periodically throughout the heating season for any obstructions.
FORCE Installation, Operating & Service Manual 13 Boiler Cleaning (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.
FORCE Installation, Operating & Service Manual 14 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 FORCE OIL 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.
FORCE Installation, Operating & Service Manual 14 Troubleshooting (continued) NOTICE: CHECK TEST PROCEDURE. A very good test for isolating fuel side problems is to disconnect the fuel system and with a 24" length of tubing, fire out of an auxiliary five gallon pail of clean, fresh, warm #2 oil from another source. If the burner runs successfully when drawing out of the auxiliary pail then the problem is isolated to the fuel or fuel lines being used on the jobsite. B. OIL PRIMARY CONTROL (Oil Primary) 1.
