Only three options here first check for shorted wires , second bad thermostat (try unplugging thermostat wires one at a time if possible to see if unit turns off, this will also tell you if the gas valve is stuck open if you take all the wires off the thermostat and the thing still reuns, ) good luck.

Some thermostats have a default lower limit such as 60 degrees to prevent complete loss of heating. The lower limit is not set by the user.

Thermostat is not shutting off heater..... can't adjust....gets room too hot. I keep on pilot only this is a EMpire RH25


Your heater uses a capillary bulb type thermostat sensor. If the small copper tubing that runs from the copper bulb to the control valve ls bent or crimped, it won't work properly or at all. Try setting the temperature at the lowest level, so that the room heats up gradually. Then, see if the Thermostat shuts it off. Also check the air intake on the front of the heater to make sure it's not obstructed or clogged in any way. If all else fails, contact Empire Comfort Systems Technical Service Dept @ 800-851-9396.

Hope this helps you troubleshoot and solve the problem.

Our coleman fireplace insert starts to warm and then shorts out


Not sure if you have an electric fireplace or a gas fireplace. But, from the way you worded the description of your problem, I'm going to assume that it's electric. I'm also assuming that all the other features of the fireplace work, but the heater doesn' t. If that is the case, below is what the Owners Manual recommends doing.

5. Flame effect operates, but heater does not blow warm air

The TEMPERATURE button is a thermostat control for the heater. Each preset temperature setting has a different thermostat setting as shown to the right:

The heater will NOT activate if the room temperature is above the thermostat setting. If the ambient room temperature is 78° F the user will need to select Setting 3 in order for the heater to be activated. It is normal in warmer climates and in rooms with higher ambient temperatures for the heater to not activate on the lower settings due to the thermostat control. 5a. Try increasing the temperature setting. See drawing:

temp-control-fig.jpg 6. If unit heater does not function, but Power and Heater switches are in the "ON" position and thermostat is set on "HI" 6a. Turn all switches to the "OFF" position and unplug the unit from the wall outlet for 5 minutes. After 5 minutes plug the unit back into the wall outlet, and operate as normal.

My empire wall furnace does not ignite. It has gas flowing because the pilot is light, i have changed the thermostat and wired it two different ways in case I reversed them. What is next? Could it be the...


It could be several things: Is the Control Knob turned from Pilot to ON? If that is the case, wait a few minutes after turning it to ON. That will allow the Thermopile to heat up sufficiently. Be sure the flame is touching the Thermopile. If everything looks correct turn up your Thermostat to higher than the ambient room temperature and see if the burners light. Remember to turn your Wall Thermostat down to the lowest temperature setting before turning the knob from Pilot to ON.

FYI - That Wall Furnace does not have a Thermocouple. It uses a Thermopile instead to generate millivolts of electricity to open the gas valve and maintain the pilot flame.

If it is the Thermopile, you can order it directly from Empire Comfort Systems, as well as download your Owners Manual at www.empirecomfort.com

Reddy heater 70,000 with factory thermostat will run a few


Set the pump pressure. If correct check the nozzle. Desa recommends annual replacement.

A worn nozzle creates a spray pattern, where a good nozzle creates a fog. With a coarse spray pattern poor combustion results in an off color flame, . The photocell doesn’t like the color, sends a signal to the computer which shuts everything down. That’s the job of the electronics.

RTH6300B - Not blowing the hot air


I currently have a 2 wire system. I have one red and one white. I hooked the red to the R and the white to the W. I had to go into the system setup using the UP arrow button and the FAN button. The first setting is the 1 setting, and I selected number 2 ( Heating Only ). Then the 5 setting. I selected number 1 ( Gas/oil steam or gravity system ). Then 14 is usually 0 for Fahrenheit. I was just messing around and that is the buttons I used and I tested it. The furnace kicked on and then 10 to 15 secs later the air began to blow through the vents. I hope this works for others who read this.

Can someone please tell me what is the lowest temperature setting a Fahrenheat 3000 Watt Large Room Fan-Forced Wall Heater Model FZL3004 will turn on at ?


about the only way I can figure is to let the room get very cool and adjust the thermostat to its lowest setting. now turn on the unit. monitor the heat until the stat just opens. the thermostat bimetal will be closed and will open when the bimetal expands and opens its contacts. another way is to hitch up a chart recorder to measure temperature with its output connected to the heater. [too expensive for you or the DIY to accomplish]
