The wall above the furnace gets hot, but not too hot to touch. The blower is entirely optional and doesn't change the BTUs you are putting into the space.

The gas valve is on the left, so you need to bring the gas line up through the floor on the right. This heater is controlled by the energy produced from its pilot light. This model must be vented to the chimney.
