Expected temp out of heater vents

at the spec sticker inside the unit. It will tell minimum & maximum temp rise. Example might be 40-70. That means you should never have less than a 40 degree rise or more than a 70 degree rise. Now, these temps should be taken near the furnace. Incoming by the fiter, outgoing 4-5' from the furnace in the ducts. Take a few readings and average them. If you aren't in that range, your dealer should check firing rate or blower speeds.

    Propane heater temp

    My wife complains (nicely) about the temperature of the air coming out of our vents. The fan does come on before and stays on after the furnace comes on, as I am sure it is supposed to. I am thinking of putting a max/min thermometer in a vent nearest the furnace. What max temp should I expect? It is a high-efficiency heater, that vents/brings in air from the outside via pvc pipe.
    I am trying to figure out why it seems to be using more fuel than other years. I had it looked at, but they found no problems.
