I'd recommend stripping out the library calls to keep things simple (basically everything past TF2CustAttr_GetAttributeKeyValues minus keeping TF2_AddCondition intact and removing the include reference). Every minigun will work then.

But if you're keeping the calls and using my library, you'll also likely want to install tf_custom_attributes_manager, which is what actually reads the config and applies the attribute. The configuration is also set to only apply this effect to the Huo-Long Heater; add a section as appropriate for your preferred minigun (based on defindex), and reload and reequip with tf2custattrman_reload.
