V Knockdown Boiler Assembly Instructions A. Prior To Assembly 1) Thoroughly inspect the cast iron heat exchanger sections for any shipping damage, i.e. cracks in the castings, broken lugs or punctures due to mishandling. 2) Do not use a damaged heat exchanger section. Replace it with an undamaged heat exchanger section. 3) Keep the base in the shipping carton until it is time to perform the assembly. This keeps foreign material from contaminating the burners or creating other hazards.
11 Figure 4: Multiple Base Assembly
C. Section Assembly 1) Clean the boiler sections inside and out to remove dirt due to shipping and handling. 2) Clean all nipples and nipple ports with kerosene immediately prior to section assembly. 3) Set the left end section on the base so that the locating lugs on the bottom of the section go inside the front and rear base panels. Left end sections are identified by “LEH” cast on the section. Right end sections are identified by “REH” cast on the section.
Figure 5: Use Of Nipple Gauge Figure 6: Assembly Of Sections 13 15
14) Install the tankless coil/s and/or cover plates using the gaskets and 3/8 x 7/8 bolts and washers provided (see Figure 7). 15) Test assembled block for leaks. Unless local codes have other requirements, use the following procedure: a) Run a hose from the water service to one of the lower tappings. Install a ball or gate valve in one of the tappings on the top of the block and connect the other end of this valve to a drain. Install a gauge in any other convenient tapping.
NOTE Installation of the draft hoods will be easier if one person supports the rear of the hood while another installs the carriage bolts, nuts and washers. 6) Hang a rear tie rod channel bracket on the 4" stud installed in the left end section (Figure 12a). 7) Facing the rear of the boiler, find the square mounting holes underneath the draft hood. Drop a 5/16 x 5" carriage bolt through this hole and through the hole in the rear tie rod channel bracket.

VI Air For Combustion and Ventilation Sufficient fresh air must be supplied for combustion, ventilation and flue gas dilution. Provisions for combustion, ventilation and flue gas dilution air for gas utilization equipment vented by natural draft must be made in accordance with local building codes or, in absence of such codes, in accordance with the National Fuel Gas Code, NFPA 54/ANSI Z223.1. Warning An adequate supply of combustion and ventilation air must be provided to assure proper combustion.
Figure 15: Boiler Installed In Confined Space, All Air From Inside • If providing openings into adjacent rooms is undesirable, combustion and ventilation air can be brought into the boiler room from outdoors. See the instructions under “For Buildings of Unusually Tight Construction”. B. For Buildings Of Unusually Tight Construction 1) Provide outdoor air through two permanent openings which communicate directly or by duct with the outdoors or spaces (crawl or attic) freely exchanging air with the outdoors.

Figure 19: All Air From Outdoors, Using Horizontal Ducts Into The Boiler Room 24 22
VII Venting Vent installation must be in accordance with local building codes, or the authority having jurisdiction, or the National Fuel Gas Code, NFPA 54/ANSI Z223.1. Typical vent installations are shown in Figures 20 and 21. The vent system shown in Figure 20 uses a common vent for all boiler modules. In Figure 21, each boiler module is equipped with its own vent.
6) Lateral venting should slope upwards towards the chimney not less than one inch in four feet. No portion of vent pipe should run downward or have sags. Vent pipe must be securely supported. 7) The connector rise coming off the boiler should be as tall as possible, while still maintaining the proper clearance from the horizontal vent connector to combustibles and the proper pitch called for in (6) above. 8) Lateral vent pipe should be installed above the bottom of the chimney to prevent blockage.
Figure 20: Typical Series 32 Venting (Common Module Venting) Figure 21: Series 32 Venting (Each Module Individually Vented) 27 25
Removing An Existing Boiler From A Common Chimney In some cases, when an existing boiler is removed from a common chimney, the common venting system may be too large for the remaining appliances. At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation.
VIII Steam Boiler Piping & Trim Installation CAUTION • INSTALL BOILER SO THAT THE GAS IGNITION SYSTEM COMPONENTS ARE PROTECTED FROM WATER (DRIPPING, SPRAYING, RAIN, ETC.) DURING APPLIANCE OPERATION AND SERVICE (CIRCULATOR REPLACEMENT, ETC.). • OPERATION OF THIS BOILER IN A SYSTEM HAVING SIGNIFICANT AMOUNTS OF DISSOLVED OXYGEN CAN CAUSE SEVERE HEAT EXCHANGER CORROSION DAMAGE. A.
Hydrolevel CG450 – This is a probe type LWCO and is installed in tapping “G”. On the CSD-1 control package, and other boilers with redundant low water cut-offs, the CG450 is the operating low water cut-off and should be used to control a feeder (if used). The CG450 supplied with the Series 32 uses a special probe which does not have a mounting flange. Install this probe in tapping “G”. DO NOT INSTALL WITH TEFLON TAPE.

B. Indirect Water Heating Piping (Steam Boilers) The steam version of the Series 32 boiler is equipped with tappings to permit the connection of a Crown Mega-Stor, or other indirect water heater. In this type of system, hot boiler water is drawn from below the water line and passed through the heat exchanger in the indirect water heater. This section describes boiler-side piping only. Refer to the indirect water heater instruction manual for domestic water piping.
IX Water Boiler Piping CAUTION • INSTALL BOILER SO THAT THE GAS IGNITION SYSTEM COMPONENTS ARE PROTECTED FROM WATER (DRIPPING, SPRAYING, RAIN, ETC.) DURING APPLIANCE OPERATION AND SERVICE (CIRCULATOR REPLACEMENT, ETC.). • OPERATION OF THIS BOILER WITH CONTINUOUS RETURN TEMPERATURES BELOW 120°F CAN CAUSE SEVERE HEAT EXCHANGER CORROSION DAMAGE. • OPERATION OF THIS BOILER IN A SYSTEM HAVING SIGNIFICANT AMOUNTS OF DISSOLVED OXYGEN CAN CAUSE SEVERE HEAT EXCHANGER CORROSION DAMAGE.
DANGER • CONFIRM RELIEF VALVE HAS THE CORRECT PRESSURE SETTING AND CAPACITY FOR THE BOILER. • PIPE THE PRESSURE RELIEF VALVE DISCHARGE TO A SAFE LOCATION. • DO NOT INSTALL A VALVE IN THE RELIEF VALVE DISCHARGE LINE. • DO NOT PLUG RELIEF VALVE DISCHARGE. 3) In addition to the boiler trim, the following system components are required: a. Circulator - The best circulator location is usually on the supply piping just downstream of the expansion tank as shown in Figure 30. b.

B. TANKLESS HEATER PIPING If the Series 32 water boiler is installed with an optional tankless heater, pipe the heater as shown in Figure 32. The components in this system and their functions are as follows: 1) Mixing Valve (Required) - During the heating season, the water exiting the tankless heater may be 180 degrees or more. The mixing valve blends hot water leaving the tankless heater with cold water so as to maintain the hot water supplied to the fixtures at a fixed temperature.
8) Multiple Tankless Heaters - If two tankless heaters are installed in the boiler, it is recommended that each heater be installed in parallel with its own mixing valve, relief valve, flow restrictor, etc.. This will permit either heater to be removed from service for maintenance while still providing some domestic water to the building.
X Gas Piping 1) Gas piping to the boiler must be sized to deliver an adequate supply of gas for the boiler to fire at the nameplate input with the inlet pressure at the gas valves between the minimum and maximum valves shown on the rating plate. For more information on gas line sizing, consult the Utility or the National Fuel Gas Code. 2) Figure 33 shows the typical gas piping connection(s) to the Series 32 boiler. A sediment trap must be installed upstream of all gas controls.
XI Control System Wiring WARNING All wiring and grounding must be done in accordance with the authority having jurisdiction or, in the absence of such requirements, with the National Electrical Code (ANSI/NFPA 70). 1) Provide the boiler with a dedicated branch circuit with a fused disconnect. The minimum rating of this circuit must be 15A. 2) Wire the boiler following the appropriate wiring diagram in Figures 35 or 36. Use 14 gauge wire for all 120 volt boiler wiring.
6) Once the ignition module detects the presence of a pilot flame, voltage is applied across the main valve, opening the valve and establishing main flame. 7) The way in which the ignition module handles failure to establish pilot or the loss of an already established pilot depends upon the exact ignition module supplied with the boiler. For more information on module operation, consult the ignition module instructions supplied with the boiler or the local Crown representative.

Figure 36: Series 32 - CSD-1 Boiler Wiring 50 48
Safety Control Operation Temperature Limit Control (Water Boilers) – The temperature limit control interrupts burner operation when the supply water temperature exceeds the set point. Maximum allowable water temperature in a water boiler is 250F. The L4006A will reset itself when the water temperature drops below the set point less the differential (typically 15F). Manual reset water limit controls, such as the Honeywell L4006E, must be manually reset.
XII Start-up and Checkout NOTE SAFE LIGHTING AND OTHER PERFORMANCE CRITERIA WERE MET WITH THE GAS MANIFOLD AND CONTROL ASSEMBLY PROVIDED ON THE BOILER WHEN THE BOILER UNDERWENT THE TESTS SPECIFIED IN Z21.13. Use the following procedure for initial start-up of the boiler: 1) Make sure that the boiler is filled with water. 2) Check all new gas piping for leaks and purge piping sections that are filled with air. See the National Fuel Gas Code for additional information on testing and purging gas lines.
WARNING FAILURE TO FOLLOW THE FOLLOWING PROCEDURE EXACTLY COULD RESULT IN OVER-FIRING OF THE BOILER AND A CARBON MONOXIDE HAZARD. 13) Check the manifold pressure and adjust if necessary. To do this, use the following procedure: a. Connect a manometer to the inlet pressure tap on the gas valve (see Figures 39 - 41). b. Check the inlet pressure with all gas appliances on and off.
16) (Steam Boilers) - Verify low water cutoff operation while the boiler is running. Slowly open drain valve and drain boiler until the water level drops below low water cutoff line. Water still should be visible in the gauge glass when the low water cutoff shuts down the main burners. The pilot burner and main burners should stop firing. Make sure pressure limit, thermostat or other controls have not shut off the boiler. Upon test completion refill the boiler to the normal water level.
