Aquastat Wiring Requirements

I am installing a secondary aquastat on my gas furnace to keep the circulator pump running after the boiler shuts off. I got the information on how to wire the aquastat from an old thread. The diagram states that you must use wire that is rated for use on boiler systems. My question is, how to determine what type of wire is needed and where to purchase? Any help is appreciated.

Presuming this to be a line voltage aquastat, you would need to use Type MC cable. This cable is usually THHN wire inside a flexible metal case. Most home improvement stores carry it.
