20 Most Recent Fahrenheat (FFH1614) Wall Mounted Panel Heater Questions & Answers

Make sure that the heater is mounted where convection currents occur freely. When heat builds up around the top of the heater its temperature will rise uncontrollably. You'll be luck not to get a fire.

You need to check the breakers or the actual power because I see the 1614 model as being 240 Volts. Unless you can change that rating inside the unit itself and it has been set to 120 Volts. IT appears from the wiring code you listed that the building wires are 120 volts. However a meter would be the definitive answer. When you are running 240 or higher (double phase) Black and Red are hot and white is neutral If it is 110 then black is hot and white is neutral. Since I cannot tell from the description posted whether the red is source or inside the heater, you really need a volt meter.

I'm not aware of a wall thermostat for this heater, because it does not have a Millivolt Control. As far as the vibration is concerned, does it just occur when the fan is on? If so the fan or the fan motor may be loose. Or the fan itself is out of balance. As make sure the fan housing is properly attached to a wall stud or studs.

Make sure it's turned off. Better yet, turn off the circuit breaker to the heater. Remove the cover by unscrewing the 2 screws that hold the front cover in place. Use a vacuum with a brush attachment to vacuum the blades, as well as the interior of the heater. If necessary, use some canned compressed air (like you clean a computer with) with the straw nozzle attached, to blow out any areas the vacuum can't reach. Then vacuum again. Replace the cover with the 2 screws you removed. Turn the circuit breaker on and you're back in business.

Cleaning should be done twice a year.

UNIT SOUNDS LIKE ITS SHUTTING DOWN ON A LIMIT SWITCH IN HEATER. THEY LOOK LIKE ROUND BUTTONS OF DIFFERENT SIZES. THE HAVE 2 WIRES GOING TO THEM AND THEY ARE A NORMALLY CLOSED. THERE IS A FAN DISK NORMALLY OPEN TO UNTILL IT GETS HOT AND CLOSES TO TURN ON FAN.  IF THE FAN SWITCH TAKES TO LONG TO CLOSE THEN LIMIT OPENS TO PROTECT FROM OVER-HEATING

Yes you are right but adding a ground wire to the heater will make it more secure.So run a different wire bolted or attached to the case of the heater somewhere and connect it to the earth wire.

Read the instruction manual that ships with the unit for clearences from combustionalbles. Usually the engineers design the unit to be mounted with a half inch gap around the internal frame but the outer cover may touch the surrounding paneling. it is best to check the installation guide. The unit return or suppy air may not be blocked or impeaded in any way.

I am assuming this is an electric wall mount heater, if the unit is drawing current then it should relate to heat as 3.41 btu is = 1 watt.
take the voltage reading and the amp draw and mutiply them to determine the wattage eg; 240 volts x 20.8 amps = 5000 watts = 17,050 btu. if the unit is fan assited and you are drawing 1 to 2 amps this would indicate the fan is runnning without the heat element being energized hope this helps

theis is the safety swith that senses overheating. If the fanmotor cuts off and the heater elements don't, this switch will sense excessive heat and open the circuit for both the heater fan and the heater element(s). If it is "shorted" it is because it is cool and not needing to activate to interrupt the power. The problem I am having is that the switch opens prematurely after just a coule minutes of operation. the unit has to cool down befoe it wll cycle on again for just a few minutes.
Trying to find the part nubmer for the switch.

if its a 1500 watt and I think it is ...use a 20 amp breaker
