In Canada, installation must be in accordance with the B149.1 Installation Code • Where required by the authority having jurisdiction, this installation must conform to the Standard for Controls and Safety Devices for Automatically Fired Boilers (ANSI/ASME CSD-1). 2) BWC boilers utilize aluminum heat exchangers constructed, tested, and stamped in accordance with ASME Boiler and Pressure Vessel Code Case 2382. Some jurisdictions which require ASME boiler construction do not recognize this Code Case and may not approve the installation of an aluminum boiler. Consult the authority having jurisdiction before installing this boiler. 3) Read Section VII to verify that the maximum combustion air and exhaust pipe lengths will not be exceeded in the planned installation. Also verify that the vent terminal can be located in accordance with Section VII. 4) Make sure that the boiler is correctly sized: • For heating systems employing convection radiation (baseboard or radiators), use an industry accepted sizing method such as the I=B=R Heat Loss Calculation Guide (Pub. #H21 or #H22) published by the Hydronics Institute in Berkely Heights, NJ. • For new radiant heating systems, refer to the radiant tubing manufacturer’s boiler sizing guidelines. • For systems including a Crown Mega-Stor indirect water heater, size the boiler to have either the DOE Heating Capacity required for the Mega-Stor or the net rating required for the heating system, whichever results in the larger boiler. • For systems that incorporate other indirect water heaters, refer to the indirect water heater manufacturer’s instructions for boiler output requirements. 5) Make sure that the boiler received is configured for the correct gas (natural or LP). 6) Make sure that the boiler is configured for use at the altitude at which it is to be installed. IV Locating the Boiler 1) Observe the minimum clearances shown in Figure 4.1. These clearances apply to both combustible and noncombustible materials. Observe the minimum clearances to combustibles for vent pipe shown in Table 4.2. 2) Note the recommended service clearances in Figure 4.1. These service clearances are recommended, but may be reduced to the combustible clearances provided: a. Access to the front of the boiler is provided through a door. b. Access is provided to the condensate trap and transformer located underneath the boiler. 3) When the boiler is installed on the floor using the optional pedestal kit, the boiler may be installed on a noncarpeted combustible surface. 4) The relief valve must be installed in the factory specified location. 3 NOTICE This product must be installed by a licensed plumber or gas fitter when installed within the Commonwealth of Massachusetts. See Appendix A for additional important information about installing this product within the Commonwealth of Massachusetts.
