"But, does this mean that Zabimaru, or at least it's complete Bankai, is a fire-type Zanpakutô? Or was the force that turned Mask into ashes, just a Bankai technique?"

I doubt it. We have seen other zanpkutos with fire like attack apprence/effects but all they are is kai blasts.

Take Ichigo's his GT has left people with what looks like burns right? But it is still a melee type.

Well all this is depending on future chapters with more info.
