A drain line from the relief valve should terminate near a suitable drain. Do not thread, plug, or cap the end of the drain line. The pressure setting of the relief valve should not exceed the pressure capacity of any component in the system including the boiler. HIGH TEMPERATURE DEVICES Automatic Device The boiler control circuit contains a high temperature cutoff switch. This device shuts off the heating elements if excessive water temperatures are reached. The high temperature cutoff has an a
