For all sidewall horizontally vented gas fueled equipment installed in every dwelling, building or structure used in whole or in part for residential purposes and where the sidewall exhaust vent termination is less than seven (7) feet above grade, the following requirements shall be satisfied: a. If there is no carbon monoxide detector with an alarm already installed in compliance with the most current edition of NFPA 720, NFPA 70 and the Massachusetts State Building Code in the residential unit served by the sidewall horizontally vented gas fueled equipment, a battery operated carbon monoxide detector with an alarm shall be installed in compliance with the most current edition of NFPA 720, NFPA 70 and the Massachusetts State Building Code. b. In addition to the above requirements, if there is not one already present, a carbon monoxide detector with an alarm and a battery back-up shall be installed and located in accordance with the installation requirements supplied with the detector on the floor level where the gas equipment is installed. The carbon monoxide detector with an alarm shall comply with 527 CMR, ANSI/UL 2034 Standards or CSA 6.19 and the most current edition of NFPA 720.

The BFIT heat exchanger adds pressure drop to the system which must be accounted for in the design of the piping configuration and pump selection. 2. The system should be designed to maintain the operating water flow rate shown in Table 23 while never exceeding the range of absolute flow rates shown in Table 24. Exceeding the maximum water flow rates can cause pipe erosion, damage the flow switch, and allow unsafe operation. a. Maintaining sufficient flow through the heat exchanger will help prevent the buildup of scale. Table 25: Temperature rise, flow rate, and head loss Recommended Range Delta 20 °F...
  • Page 41: Pump Selection

    IX. Water Piping (continued) G. Pump Selection A Circulation pump is a required component for complete installation of this appliance. Choosing the appropriate pump is critical for the functionality, safe operation, and longevity of the appliance. Pumps should be sized for each particular installation based on the required flow rate, water hardness, and total pressure drop in the primary loop between the tank and the water heater. 1. Sizing a sufficient pump will ensure the desired temperature rise and meet the minimum flow rate requirements. Lower flow rates will allow build up of scale and cause more stress on the heat exchanger. a. If the flow rate is too high and the temperature rise is too low, the flow rate can be decreased by adding a restriction in the loop. i. Install a ball valve or globe valve (recommended) in the outlet side of the primary piping. ii. With the water heater at its maximum input rate (high fire), slowly adjust the globe valve until the temperature rise is within the recommended range shown in Table 25. iii. Water velocities too high may cause erosion within the tubes of the heat exchanger or the primary piping. Failure to adjust the flow rate to the specified values or use the appropriate pipe size can cause non- warrantable damage.
