garage heater

[rollie]

When I bought my house in 96 it had a natural gas heater already installed.
what i'm wondering about is the way it runs. my garage is 20x21 with a 10 ft ceiling, walls and ceiling are insulated. my heater is a reznor 60000 btu and when it runs the forced air fan only shuts off for a couple minutes before it fires up again. can someone tell me why this is? the thermostat is located to the side of it on the interior house wall and about a foot below and 1/2 a foot in front.

thermostat if at all possible sould be about head high and behind the furnace if at all possible.

What about temperature 'regulation'... Is the temp what you expect, or does it get too hot/too cold? A 400 sq ft building, with 60K BTU should not run that much, IMHO, I don't see mine running that much (150K for 1800 ft).

Also what is your set temperature?

are you talking about the fan turning on and off very fast? There should be a dial thermostat inside the furnace to bring the furnace fan on at 150 degrees and off at 85-100 degrees. You can usually reset these lower , but remember- extreme temperature changes kills heat exchangers
