300k BTU boiler temp &pressure relief valve

[mark cline]

I had misplaced the t&p valve for my Econoburn 300 k boiler , I was going to get a new one before startup but don’t recall the specs. on the valve tags . Anybody with a 300 k boiler care to help me out? Thanks Mark

Typically a temperature and pressure relief valve as found on most water heaters for domestic water use. For boiler use I believe you only need the pressure relief type set to release pressure at 30psi - At least that's what I used on my systems.

I did see that on different sites , but I’m sure mine was temperature and pressure . Could be wrong though. I did find one online set at 30 psi but only rated for 105 k btu/ hr and my boiler is 300k.

The 30 psi makes it a rare bird:
