There is not much to clean in this heater. I usually take a long handled bottle brush and scrub the burner. I check the pilot light and inspect the venting system for blockage.

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.

I have a wall mount 25000 btu empire. It keeps clicking on and off trying to light up. after about 4 or five tryes it starts, runes for a short time and shuts off. A funny noise comes from the burner area....

You're heading in the right direction. Especially, with a 10 year old heater that's never been cleaned.
Using a vacuum (a shop vac is great for this) that has a hose and brush attachment will do the job. Also, canned compressed air with a straw nozzle (like you clean your computer with) can be used to blow out the pilot tip and reach areas the vacuum can't.

After you've cleaned the heater, check for wear and damage to any of the internal parts. Especially, any wiring that may look burned or frayed. Also, be sure that the exhaust vent damper is working properly and the exhaust vent piping is free from obstructions. The clicking you heard may have been from the automatic safety damper switch.

If after 10 years you can't find your Owners Manual, here's a link to it. It will assist you any cleaning the unit and spot any problems.

Good luck and remember to clean the wall heater annually.

I keep my heater off with just the pilot burning most of the time. When I turn it on (turn up the thermostat) it can take 12 or more hours before the burner lights. After it lights the blower cycles on and...

The Thermopile may be weak and is taking to long to completely heat up to open the gas valve. Or the combustion chamber may need cleaning. Since it seems to work ok, when the front panel is off. Either way, it's best to let a qualified serviceman make those repairs.

Low flame and heat output want 2 clean burners etc

This can be done by using an air compressor. Just simply blow out the orifices and the injection tube. That will clean everything out. This may also be a propane pressure problem. Try cleaning it first and then check the inches of water on propane or natural gas.

Does not put out enought heat

Hi this is tech crazy

the solution and reason to the problem mentioned by you is as follows:

As cold water comes in, it remains at the bottom of the tank because it is denser than hot water. If you use the hot water faster than the heating elements can heat the incoming cold water, and if you consume all of the hot water that the tank holds, you run out of hot water in the middle of your shower. If this seems to happen too often, it could mean that the bottom heating element in an electric water heater has burned out or that your water heater is too small for your house. Or it could mean that you are taking really, really long showers.

Hope this helps u a lot

Please do rate me on the above said solution

Whistling Heater

there may be an obstruction in the burner tube where the gas mixes with air. look for a spider web or similar.
