Live steam hazard. If the Burner and the Pump stop at the same time, wait at least 15 minutes before starting the filter pump to avoid severe damage to the heater. PRESSURE RELIEF VALVE Canadian code requires and some U.S. local codes may require installation of a pressure relief valve. Purchase separately and install a 3/4” pressure relief valve complying with the ANSI/ASME Boiler and Pressure Vessel Code, having a capacity equal to the Btu/hr rating of the heater.
