Question about Fahrenheat Ceiling-Mount Industrial Heater - 7500 Watt

Fahrenheat fuh 54 b does not run long enough to get garage warm

Fahrenheat fuh 54 b doesnt run long enough to get my garage warm. the unit works great when its running. it runs for about 5 minutes then cools off and shuts off for about 10 minutes thats even on high if i put on a lower setting it barely kicks on. i live in st. louis mo. my garage is also a 22 x 21 that is insulated and drywalled with 9 foot celings. i know the unit is a touch small b.t.u. wise but i think it should keep running until it hits a certain temp. it takes a long time to get warm it will not get above 68 degrees for nothing and that takes hours. i can actauly warm the area better with two 1500 watt space heaters and get the temp. in the 70's faster. the unit has been like this since new.

Have you checked what the operating amps are vs. the amps provided by the outlet. Sounds like you are trying to pull to much load and the machine probably has a saftey to where it shuts down bofore it buns itself up. Hope this helps. You have to be real careful about overloading circuts.

Fahrenheat 54b won't stay running long enough to heat

Fan maybe running to slow and allowing the elements to get too hot and open circuiting the cut out. This will be a fault with the fan or maybe dust and debris in the intake vents.

Could be either. But, I suspect that wiring is getting hot enough to trip the breaker. Check all of your wiring to see if there is a hot spot or insulation melted.

You could tripping the high temp limit this will be located near the heat exchanger When it shuts how long does the blower motor stay running? Do you have a meter?

I have a farenheat fuh 54 b the fan turns slow until I tilt it towards the floor and then it spins fine. Checked for loose or broken wires and found none.

I would clean fan blades and motor housing. Blow out motor with compressed air if possible and check for oil ports on both ends of motor housing. If your motor has oil ports they may have plastic or aluminum plugs in them. If so remove themand put 3-4 drops of fine grade oil in. I hope this helps. Thanks

Hi, I just purchased a FUH-54B at Northern Tool and Equipment and installed it this evening. I have a 30 amp double pole breaker installed, and I have 120V at L1 and 120V at L2. The ground is properly...

It sounds like you have 120v from line 1 and line to to ground. What do you have between line 1 and line 2?
You should have 220 or 240v. If you dont have this
the problem is at the breaker. Are the wires going to the same breaker?

If you do have 220 or 240 between line 1 and line 2 at the unit, then it appears thr problem is at the unit,
probably the thermostat isn`t turned up high enough?

If it has a contactor, is it pulled in? If not then there is
a control problem. If you are skilled and confident you
could simply push the contactor in and it should
operate or have an electrician do it. Most of the time
you can bypass the thermostat and close the
contactor that way.

I have the Fahrenheat Model FUH 724 heater. The manual states that it can be wired as a 240v 7500W unit but the directions and the unit itself only allow for three wires to be connected Black, White, and...

1st you will belucky if you actually have 240 v, most
homes are usually 220v. In youyr case you need to start at the breaker panel.

This is an example:
You have a Double Pole Single Throw breaker. Black
Wire is hot and goes into one side of breaker,if you havea red wire that goes into the other have of the

The white wire ties in the nuetral bar and the bare wire into the ground bus bar. At the unit you hook up the red and the black wire which will supply the 240
Volts, you could tie the white and the ground wires together into the grounding terminal

Installing FUH cealing heater used 10-3 wire

If you use the white wire as a hot wire, you must identify the wire as being a hot wire at the breaker panel and the unit. The white
wire must be marked about 6 inches back from the terminal
connections with black paint or wrapped with black insulation tape.

It would be easier to use the red wire, since most electricians would identify it as being a hot wire
