Page 4: Product Description
I. Product Description The Bimini Buddy is a factory assembled near boiler piping module that is designed for use with Crown Bimini (BWC) series boilers. The central component in this product is a hydraulic separator that is designed to assure that the minimum required flow through the boiler is always maintained regardless of the flow through the heating system. This separator is also used for air removal as well as the connection point for the expansion tank. - Page 5 Automatic Air Vent (Not Supplied) Expansion Tank (Not Supplied) FIGURE 2.1: Bimini Buddy (With Cover Installed ) FIGURE 2.2: BB100H (Heat Only - Shown with Cover Removed)

Refer to Table 5.2, 5.3, or 5.5 as appropriate for the type of Bimini Buddy being installed. Verify that the equivalent length calculated in Step 4 is less than that shown for the combination of boiler, circulator, and indirect water heater (BB100I only) being installed.

VI. Domestic Water Piping (BB100C) WARNING Like all domestic water heaters, the BB100C is capable of generating water that is hot enough to cause injury or death due to scalding. To minimize the risk of scalding: • Set domestic hot water (DHW) temperature as low as possible (see the Start-up Section of this manual for information on setting domestic water temperature. - Page 17 To Fixtures Hose Bib Valve Ball or Globe Valve Flow Restrictor Thermostatic Mixing Valve (Not Supplied) DHW Relief Valve (Max Setting 150 psi ) Hose Bib Backflow Preventer Valve Cold Water In FIGURE 6.0: BB100C Domestic Water Piping...

VII. 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). This manual covers wiring the Bimini Buddy into BWC series boilers using having two different control systems: • Control Systems using Honeywell Type III MCBA - This control system has been used on all BWC series boilers manufactured between 2005 and late 2010. - Page 19 Heating T-Stat Low Voltage Wiring Low Voltage Terminal Strip Line Voltage BK - Black WT- White Wiring R - Red BL - Blue Line Voltage Factory Wiring Line Voltage Field Wiring (N.O.)

Connect the three way zone valve in the BB100I to the blue lead and neutral (white) in the boiler’s J-box. If the system has a single system circulator having a draw of less than 1.5A, the system circulator can be wired in parallel with the zone valve (after reprogramming the MCBA per part G of this manual, the zone valve will be powered during a call for heat).

Page 22: Start-Up
VIII Start-up The following steps must be taken in addition to those shown in the boiler instruction manual in order to commission the Bimini Buddy: If not already done, flush the system so that it is free of sediment, flux and any residual boiler water The Bimini Buddy must be purged of air. If it is piped in accordance with Figure 5.0, this can be done simply by opening the fill valve and making sure that the automatic air vent is open. Otherwise, the screw driver vent shown in Figure 5.1 must be also be opened until a steady stream of water comes from this vent. - Page 23 FIGURE 7.5: Wiring BB100C to Boiler equipped with Sola WARNING Improper setting of parameters can cause unreliable or unsafe operation, resulting in property damage, personal injury, or loss of life: • Changing parameters should only be attempted by a professional heating service technician. • Do not change any parameters not described in this manual without first consulting the factory.
