I've always wondered about the dual twin-linked heavy flamers on the Immolator model. The Codex entry states it has as Wargear: "Twin-linked heavy flamer, searchlight, smoke launchers." So it has one Twin-linked heavy flamer, but the model comes with two on the turret. So from which one do you use for placing the template? Is it either one... or is it both? Both would make it nasty by almost doubling the field of flame.
