ok true thanks for the advice. i figured the pilot needs to be upgraded to a safety one so that goes back to my original question what do i need to get. doing some research i THINK i'm not 100% the new safety valves have a built in regulator. so i would need a new valve with a new pilot assy. that had the thermocoupler. it there a kit to swapp this old stuff out?

yes standard combination valve will have a builtin regulator....will have to make a new pilot tube and install thermocupler and maybe new pilot assy ...need to see picture of old pilot assy to see if it will work with conversion...ben sr

Oh just remembered when i bought this house i had a home inspector go over the whole house in the part where the heating system is listed he did say the heating system is original to the house 1959. during his inspection to the furnace he stuffed what looked like a camera on the end of a flexabile wire hooked up to a small laptop up inside above the burners and down the other side. and said for it's age it was well maintained and looks in safe operating condition. so i guess that was the heat exchanger he was looking at.

Inspectors, not to discredit them, are not HVAC professionals. At the very least in my encounters they have no business saying a system is safe to operate or not.

There are also adapters for testing thermocouples or attaching float protection to thermocouples which would allow you to keep your present pilot assy.

the way my pilot is lit now it the flame is split in a V. it mounts to the front of the burner assy one part of the flame streight back over the burners the other about 90* to the right to heat the thermal switch on the old pilot. so i guess the same way. i need it to point streight back and to the right where the thermocoupler will get the other part of the flame
