Boiler Wiring Question

I need to properly wire my gas boiler, currently there is romex connected to it.
I know that is a no no.

Is it OK to suspend metal clad cable from a joist to the boiler or is rigid conduit required?

if it drops more than 18" it must be ridged or fastened to a fixed board.

Thanks for responding.

I assume when you say "ridged" you mean metal conduit?

You can use EMT,no need for rigid conduit,normally secured to a joist then down into a service switch mounted on the boiler,pipe can also be secured to boiler.

No. Rigid conduit (RMC) has the same dimensions as water pipe but with a different coating that is much smoother and has straight threads instead of tapered. Intermediate conduit (IMC) is still threaded but has considerably thinner walls. Electric Metallic Tubing (EMT) is also known as thinwall conduit and cannot be threaded. It has connectors that either utilize a setscrew or a compression ring to hold the connector to the conduit.
