Injected engines have an alternate air source in case the air filter or the intake is blocked. They do not need additional heat as they do not evaporate fuel in a venturi and thus no icing in the intake path. I assume that you are reading a Moose manual for an aircraft with an IO540 engine, not the M114P engine. The M14P should have Carburetor Heat as under certain circumstances icing can form in the AK14 carburetor.
