Section 14-11.7 - Feedwater and blowoff connections

(a) All valves, pipe fittings, and appliances connected to a miniature boiler shall be equal at least to the requirements of the American Standards for 125 psi.

(b) Each miniature boiler shall be fitted with feedwater and blowoff connections, which shall not be less than one-half inch iron-pipe size unless operated on a closed system as provided in section 14-11.6 of this Subpart. The feed pipe shall be provided with a check valve and a stop valve. The feedwater may be delivered to the boiler through the blowoff connection, if desired. The blowoff shall be fitted with a valve or cock in direct connection with the lowest water space practicable. When the boiler is under pressure, feedwater shall not be introduced through the openings or connections used for the water column, the watergage glass, or the gage cocks. In closed systems the water may be introduced through any opening when the boiler is not under pressure.
