As far as I know, my boiler is original to the house, built in 1959. Its a National Boiler Corperation - 7-22, natural gas boiler. The pilot is directly off the main gas branch, not the gas valve (assume this was normal back then?). The pilot tees off to a compression fitting valve with a plunger, which continues toward the pilot nozzle (separate line but runs parallel with pilot line). The pipe (3/8”) has holes along the side. When the plunger Is pressed, the gas goes through that perforated line and ignites it from the pilot light, back towards the valve. The valve leaks a little, so I need to replace -dont know what it’s called or it’s main function is. My guess is a pilot purge line, or a pressure relief, although if a pressure relief I shouldn’t press in to allow flow through... any help would be greatly appreciated.
