SUPPLEMENTAL INSTALLATION AND OPERATING INSTRUCTIONS CSD-1 COMMERCIAL BOILER CONTROLS P/N 240010413, Rev. A [12/2013] CSD-1 COMMERCIAL BOILER CONTROLS ! WARNING C. Also, an independent pilot gas line which includes manual shutoff valve, pressure regulator and safety shutoff valve, two leak test valves on main gas valve, and manual shutoff valve located downstream of the main gas valve are added. See Fire, explosion, asphyxiation and electrical shock hazard. Improper installation could result in death or serious injury. Read this manual and understand all requirements before beginning installation. See Table #2: CSD-1 Component Carton Material List for component carton material list which replaces the corresponding list in the installation manuals. • See Table #3: CSD-1 Electronic Ignition Base Material List. Your commercial boiler is furnished with combustion side water or steam controls to meet our interpretation of the American Society of Mechanical Engineers (ASME) Safety Code for Controls and Safety Devices for Automatically Fired Boilers, No. CSD-1. Installation shall conform to the requirements of the authority having jurisdiction, or, in the absence of such requirements, to the National Fuel Gas Code, ANSI-Z223.1/ NFPA-54 (latest revision). Where required by the authority having jurisdiction, the installation shall conform to the American Society of Mechanical Engineers (ASME) Safety Code for Controls and Safety Devices for Automatically Fire Boilers, No. CSD-1. CSD-1 controls and this installation may be subject to approval by local inspectors. Additional parts or equipment may be required. Consult local authorities having jurisdiction before the installation of the boiler. CSD-1 controls furnished with commercial boilers are applicable to boilers with inputs above 400,000 Btu/hr. (Models 500-1500) Additional parts required by CSD-1 standards may be necessary to make this boiler compliant. This supplemental instruction manual should be used in conjunction with the Installation, Operation and Maintenance manual for your specific boiler. • Installed locations of additional components see Figures 1a and 1b. For CSD-1 combustion side control, light off sequence is as follows: 1. Turn on power. Set thermostat to call for heat. 2. Ignition starts to spark and lights pilot flame. 3. Ignition continues sparking about 12 seconds after pilot lights. 4. Main burners ignite. NOTICE A longer pilot flame recognition time is a design feature of this module and is correct. Gas Pressure Requirements • Maximum allowable inlet gas pressure (natural gas only) to controls in CSD-1 gas train is 14” w.c. (½ psig). CSD-1 Component Installation Based on parts listed in Installation, Operation and Maintenance manual for your particular boiler, the following changes should be made: • Verify inlet gas pressure is at least 5” w.c. but no greater than 14” w.c. • If gas pressure entering the building is greater than 14” w.c., installing contractor must provide overpressure protection on downstream piping to prevent buildup of downstream pressures in excess of 14” w.c. in event the fuel system pressure regulator fails. Complete Boiler Material List - See Table #1: CSD-1 Complete Boiler Material List. • Alternatively, gas pressure entering the building may be reduced with additional gas pressure regulator outdoors. If inlet gas pressure to this additional regulator is less than 14” w.c., then overpressure protection may not be required. Combustion Side Control : • Models 300 and 400, no changes are required to existing gas trains. • Models 500 through 1500 requirements include: A. Intermittent pilot control module is required to have maximum 15 second pilot flame establishing period and ability to perform safety shutdown and lockout in event of loss of flame signal at pilot. B. The intermittent pilot module and manual reset switch are used to replace the existing pilot module. • Consult local authority(s) having jurisdiction before installing gas supply piping to the boiler. 2 MATERIAL LISTS Table #1: CSD-1 Complete Boiler Material List CSD-1 Component Carton a & b Sections Model 300 CSD-1 400 CSD-1 500 CSD-1 Steam Trim Cartond CSD-1 AC Carton Jacket End Panel Carton Base End Panel Carton 1 L Inner R 300 1 2 1 SA-1 300 1 400 1 3 1 SA-1 400 1 1 500 1 4 1 SA-1 500 1 1 1 1 600 1 5 1 2 700 1 6 1 1 SA-2 600 1 1 SA-2 700 1 800 1 7 1 1 2 SA-3 800 1 1 1 900 1 8 1 1000 1 9 1 1100 1 10 1 1200 1 11 1 1300 1 12 1 1 1 SA-3 900 1 1 2 SA-3 1000 1 1 1 2 SA-3 1100 1 3 SA-3 1200 1 1 2 SA-3 1300 1 1 1 1400 1 13 1 1 2 SA-3 1400 1 1 1500 1 14 1 3 3 SA-4 1500 1 1 a.

In order to make the two low water cutoff devices work in the appropriate sequence, manufacture recommends locating both devices at same end of boiler. There are three different control systems for three different types of condensate returns. Figure 2 - Steam Boiler Feed Pump Return Normal Water Line Identify the three different types of condensate returns: • Gravity return - condensate is returned by gravity. • Condensate pump return - condensate is returned by pump(s), controlled by the water level in the condensate receiver tank. • Boiler Feed Pump Return - condensate is returned by pump(s), controlled by the water level in the boiler. Gravity Return And Condensate Pump Return With gravity and condensate pump return, additional control components are the same. See Table #5a and Figure #2 for tappings. • Tappings B & B location shown in Figure #2. Installation shown in Figure #3, Primary LWCO and Pressuretrol with gauge glass set. Figure 3 - Steam Gravity and Condensate Pump Return • Tappings D or F (Figure #2)- Manual reset pressuretrol and ¼” 90° brass syphon. • Tappings E & F - Secondary LWCO (w/manual reset). Use in conjunction with primary LWCO equipped on boiler. When using two LWCOs, place manual reset lower than automatic LWCO. Water must be visible in gauge glass when manual reset trips. • Figure 3 shows how to raise automatic (Series 67) LWCO 1-inch. • Remove 1” from long side of ¼” diameter 90° brass siphon tube. • Remove nipple in series 67 and replace with 1 ½” long nipple and street elbow. WATER LEVEL 29” TO FLOOR • Water level control device located on condensate receiver tank and controls condensate return pump is not supplied.

Since control receives signal from the thermostat, when call for heat is terminated, heating cycle immediately terminates and all control outputs will shut off. If maximum number of ignition trials has not been completed, control delays for 5 minute inter-purge period. After the inter-purge, control attempts another ignition trial. Refer back to Ignition Trial Period for details. Steady-State Heating Control keeps pilot gas valve and main gas valve energized while continuously monitoring call for heat and flame status. Control will remain in this steady-state heating mode until power is removed by (a) thermostat satisfied, (b) pressure switch opening, or (c) flame being lost. Ignition Trial Period Control energizes pilot gas valve and spark outputs for ignition trial time of 12 seconds. If flame is sensed during 12 seconds of ignition trial, spark output is de-energized, main gas valve is energized, and control enters steady heat mode. If flame is not established within ignition trial period, control de-energizes the spark and gas valve and operates as described below in Ignition Failure/Re-try Sequence. If call for heat is satisfied, power is removed from control, de-energizing pilot gas valve and main gas valve. If flame is lost, control will shut off main gas valve within one second, leave pilot gas on, and immediately start ignition trial. Control checks to see if maximum number of flame losses (2 per call for heat) has been reached. If maximum number of flame losses has been reached, control locks out. See Lockout section for details. Ignition Failure/Re-Try Sequence After an unsuccessful ignition trial, control checks to see if maximum number of ignition trials (2 trials) has been completed. If maximum number of ignition trials has been completed, control will lockout. See Lockout (next page) for details. 7 SEQUENCE OF OPERATION Gas Valve Sensing If either or both the pilot and main gas valves are sensed to be on when commanded to be off, or if no voltage appears at gas valve output which was commanded on, control will shut off all outputs and enter either “soft” or “hard” lockout state. Main valve is interlocked with the pilot valve and voltage can only be detected on main valve when pilot valve is energized. Control locks out the first time as “soft” lockout, then retries after 5 minutes and enters “hard” lockout state. Lockout should be manually reset as described in “Lockout.” Flame Present With Gas Off If flame is sensed for longer than 2 seconds during a period when gas valve should be closed, control will enter lockout. Power Interruptions Power interruptions less than 0.15 seconds will not cause control to interrupt heat sequence while power interruptions over 0.25 seconds will cause the control to reset lockout and ignition trial counters. Power interruptions of any duration will not cause a lockout or any other operation requiring manual intervention. Lockout Controller automatically resets from first lockout in 5 minutes. If second lockout occurs before call for heat is satisfied, it will require manually resetting by depressing red button on CSD-1 daughter board. This can be reached with a pencil through the vent holes. A red LED will also indicate lockout and can be seen through the vent holes. 8 ELECTRICAL WIRE DIAGRAMS - GAS VALVE CONTROL WIRING The suggested schematic wiring diagrams are included.
