assalamualaikum & peace be upon u all
what i know is that a safety v\v easing gear is used to operate
the safety valve manually, so when u lift up the easing gear handle
it will press the spring surrounding the v\v spindle causing the valve
to be opened up and allowing excess steam to be released so boiler
pressure dropes..tq

Are there any requirements for boiler installation?
In certain areas CSD-1 requirements should be followed. Some of these include: * One low water fuel cutoff on hot water boilers and two on steam boilers. * Safety limit controls such as pressure control on steam boilers and temperature on hot water boilers. * Appropriate safety or safety relief valves. * Listed and/or labeled burner assemblies or complete burner/boiler units. * Flame safeguard and burner management controls such as trial for ignition and purge requirements. * Fuel train requirements such as block and bleed valves, shutoff valves and pressure regulators. * See reference below
