Morphology
The meaning is directly and transparently derived from combining 'gas' (a gaseous fuel) with 'furnace' (a heating device): a B1 learner who knows both words will readily understand this as a furnace that uses gas. This is a productive noun–noun composition common across languages and not idiomatic, so no special prior exposure is required.
Etymology
Gas furnace is a clear picture: a furnace, a big heating box, that uses gas to make heat. So, it means 'a furnace that uses gas to heat a building'.
