4 3 III Before Installing 1 ) Safe, reliable operation of this boiler depends upon installation by a professional heating contractor in strict accordance with this manual and the requirements of the authority having jurisdiction.
5 4 • If the right side 24” service clearance is reduced, adequate clearance must be maintained to easily read and access the controls. Alternatively , access may be provided using a door . The right side clearances shown for boilers equipped with tankless heaters allow for removal of the tankless heater .
6 • Caulking and sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.

9 8 • The “free area” of an opening takes into account the blocking effect of mesh, grills, and louvers. Where screens are used, they must be no finer than ¼” (4 x 4) mesh.
10 9 sealed tight. 1 3 ) Do not install the vent damper in any portion of the vent system which is used by appliances other than the boiler being installed. 1 4 ) Vent damper installation is mandatory on all CWI boiler models except the CWI310-CWI379.

12 11 * VII Gas Piping Gas piping to the boiler must be sized to deliver adequate gas for the boiler to fire at the nameplate input at a line pressure between the minimum and maximum values shown on the rating plate. For more information on gas line sizing, consult the utility or Chapter 2 of the National Fuel Gas Code .
13 12 VIII System Piping Standard Piping Figure 11 shows typical boiler system connections on a single zone system. Additional information on hydronic system design may be found in Installation of Residential Hydronic Systems (Pub. #200) published by the Hydronics Institute in Berkeley Heights, NJ.
14 6) Low Water Cut-Off (Required in some situations) - A low water cutoff is required when the boiler is installed above radiation. In addition, some codes such as ASME CSD-1 require low water cutoffs. Codes may also require that this low water cutoff have a manual reset function.
15 14 FIGURE 12: INDIRECT WATER HEATER BOILER SIDE PIPING FIGURE 11: STANDARD BOILER PIPING.
16 5) Piping with a Chiller - If the boiler is used in conjunction with a chiller, pipe the boiler and chiller in parallel as shown i n Figure 15. Use isolation valves to prevent chilled water from entering the boiler.
17 FIGURE 15: BOILER PIPING WITH CHILLER FIGURE 14: ISOLATION OF BOILER FROM SYSTEM WITH A HEAT EXCHANGER 16.
18 17 IX T ANKLESS HEA TER PIPING If the CWI is installed with an optional tankless heater, pipe the heater as shown in Figure 17. 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.
19 18 3) Pressure Relief Valve (Required) - Limits the pressure in the tankless heater and piping. Use an ASME constructed valve designed for domestic water service, such as the Watts #3L. Note that this is a pressure relief valve, not a T&P valve.
20 IX Wiring Single Zone Wiring 1) 120 V olt W iring - The boiler should be provided with its own 15A branch circuit with fused disconnect. All 120 volt connections are made inside the L8148E or L8124.

24 23 CWI Control System – Sequence of Operation (Refer to Figures 18 - 21 for ladder and connection diagrams) Sequence of Operation, Standing Pilot, Less Tankless Heater 1) When the boiler is ener gized, 24 volts is immediately applied to terminals “1” (blue) and “4” (yellow) on the vent damper .
25 24 Sequence of Operation, Intermittent Ignition, Less Tankless Heater 1) When the boiler is ener gized, 24 volts is immediately applied to terminals “1” (blue) and “4” (yellow) on the vent damper . Assuming that there is no call for heat, and that the damper switch is in the “automatic” position, the damper will close.
26 XI S tart-up and Checkout Use the following procedure for initial start-up of the boiler: 1 ) Make sure that the boiler and system are filled with water. 2 ) Check all new gas piping for leaks and purge piping sections that are filled with air. See Part 4 of the National Fuel Gas Code for additional information on testing and purging gas lines.
27 WARNING • NEVER USE A FLAME TO CHECK FOR GAS LEAKS. • MAKE SURE THAT THE AREA AROUND THE BOILER IS CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE, AND OTHER FLAMMABLE VAPORS AND LIQUIDS. • DAMPER MUST BE IN OPEN POSITION WHEN APPLIANCE MAIN BURNER IS OPERATING.
28 27 1 5 ) 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 27 and 28). b) Check the inlet pressure with all gas appliances on and off.
29 28 16) Test thermostat operation while the boiler is running. Turn the thermostat to the lowest setting. For standing pilot boiler models, pilot burner should remain lit but the main burners should stop firing. For intermittent ignition boiler models both pilot burner and main burners should stop firing.

35 34 XI Service and Maintenance The following routine maintenance should be performed on an annual basis: 1 ) Turn off electrical power and gas supply to the boiler 2 ) Inspect the flue passages for signs of blockage. If there is any carbon in the combustion chamber or the flue passages, clean the heat exchanger before proceeding further .
36 Heat Exchanger Cleaning Procedure 1 ) T urn off electrical power and gas supply to the boiler . 2 ) Disconnect the damper and vent connector from the boiler . 3) Remove the upper front and top jacket panels. If possible, remove the rear and left side jacket panels.
