I don't know much about my current furnace except for it is a Janitrol. I looked inside one of the metal covers on it and found the following info:
Janitrol Conditioner Gas Fired
SIZE: FVS 140-85 TYPE A
Input BTU/hr: 140,000
Bonnet Capacity: 112,000.
How old would you say this heater is, and how efficient would you say it is capable of being? Also, there are a couple controls in this cover that I know need adjusting. The adjustment box is made by Penn, and has two knobs. One knob is for Limit Control which has a setting of 50-250, and the other knob is Fan Control which also has a setting of 50-250. Can anyone give me some info on this furnace? I know it is old, but I am wondering how old, and how efficient. Also I need to adjust those dials properly if someone could please advise me how they should be set. Thanks!
