For installations subject to UL726, a second operating control that senses water temperature is also required (not provided). Use an L4080B or equivalent. Install in the supply piping near the boiler. 2. Steam Boiler Controls: a. Install the limit / operating control, pressure gauge, gauge glass trim and safety relief valve. See Figure 7.2 (Section 7), Figure 3.7 (float boilers) and cover photo (probe boilers). b. For installations subject to UL726, a second operating control that senses steam pressure is required (not provided). Use a PA404A or equivalent. On probe boilers, install the additional pressure control opposite the standard PA404A using a cross instead of a tee along with a second brass siphon (not provided). On float boilers, install the additional pressure control in the 1/4" tapping on the top of the float low water cut-off using a vertical (360.) brass siphon (not provided). c. For application of a probe low-water cut-off, use only Hydrolevel CG450. See Figure 7.2 (Section 7) for location. See also control manufacturers instruction sheet. d. See Figure 3.7 for application of float low water cut-offs. 3. For complete information on servicing and adjustment of controls, refer to the attached control specification sheets.

GENERAL All electrical wiring shall be done in accordance with the National Electrical Code and Local Requirements. Single pole switches including those of safety controls or protective devices shall not be wired in a grounded line. B. BURNER WIRING 1. See Section 5 for mounting burner. 2. Install junction box, limit harness, and Heyco bushing, each located in the trim carton. See Figure 4.1. Mount junction box to the holes in the right side of jacket with (2) #10 x 1/2" sheet metal screws. Attach Heyco bushing to 7/8" knockout in left side of junction box. Connect limit harness to 7/8" knockout on top of junction box and insert limit harness Molex connector into Heyco bushing until it snaps firmly in place. 3. Install burner harness located in the burner carton. Beckett or Carlin – PP7024 Harness (11-1/2" conduit) Riello – PP7023 Harness (17-1/2" conduit) 4. For complete information on servicing and adjustment of controls, refer to the attached control specification sheets. 5. See the following Wiring Diagrams: Figure 4.2 - Water Boilers, Knockdown Figure 4.3 - Water Boilers, Packaged Figure 4.4 - Steam Boilers with Float LWCO Figure 4.5 - Steam Boilers with Probe LWCO Figure 4.6 - Zoning with Circulators Figure 4.7 - Zoning with Zone Valves 4. ELECTRICAL ELECTRICAL Figure 4.1: Junction Box Wiring, Steam and Knockdown Water Boilers Improper installation of burner harness can allow burner to energize with burner mounting plate open, creating a severe burn hazard to boiler maintenance personnel.

BURNER SETUP & BOILER OPERATION CAUTION Burn only #2 Fuel Oil in this appliance. Do not use gasoline, crankcase drainings or any oil containing gasoline. A. BURNER INSTALLATION 1. The oil burner is supplied with a mounting flange fixed in position. 2. Mount the burner to the burner mounting plate (item 5) with four (4) 5/16" studs and nuts provided. NOTICE Be sure high temperature gasket is between the burner mounting flange and the burner mounting plate. 3. Care must be taken when routing the oil lines so not to interfere with the opening and closing of the burner mounting plate. Flexible oil lines or flared copper disconnects with valves (when copper lines are used) may be installed to assure full opening of the burner mounting plate when servicing. NOTICE Two-pipe oil supply for Riello burner requires a separate kit. Order part #C7001026 from Riello dealer. 4. Oil burner specifications: For information pertinent to the oil burner such as nozzle sizing, fuel supply piping, adjusting or servicing, refer to the charts in this section and the burner installation manual. B. BURNER START UP AND ADJUSTMENT CAUTION Do not start the burner unless all cleanout doors are in place. 1. Burner should start automatically when thermostat is turned up and main boiler service switch is turned on. If burner does not start, check to be sure there is oil in the tank and push reset button on burner control: Beckett: Square red button. Carlin: Round red button. Riello: Round red button inside clear flexible cover on back of burner cover. If burner still does not start, contact serviceman. CAUTION Do not attempt to start the burner when ...
