Commercial Boiler replacement

IDK. I know MA writes its own plumbing code (or used to) then they would adopt NFPA 54 for nat gas and 58 for propane and print all that stuff together and sell it.

I guess they got caught printing it so now when you buy the code you just get the mass rules and regs and plumbing code and you have to go by NFPA 54 7 58 yourself.

I would say no as long as each boiler does not exceed 250,000 btu. But that is just my opinion. Since it is a commercial job the inspectors may want it.

The states adopt the CSD-1 but some states modify it so you will have to check.

Another thing I was thinking about for this job is breaking the old 2-1/2" piping and fittings.

Has anyone ever used an induction heater to remove fittings on an old boiler system ?

If you install high efficiency boilers seriously consider installing a dirt mag. There is probably rust and mud in the system piping. NOT good for new style boilers. May even want to flush out system and add inhibiter.

They will not be high efficient boilers. They will be cast iron.

Any recommendations on breaking loose the existing 2-1/2" pipe fittings?

Lots of good advice on fitting removal from HH pros in the thread below. Watch @Gordo 's video cutting a slot into the fitting and wedging the slot open to relieve pressure on the threads, then unscrewing.
