If the furnace made a clicking noise trying to turn on and then makes the BANG noise at the furnace, it’s most likely a delayed ignition. Imagine a room full of gas and then someone decides to light a match. Big problem. That's what’s happening in your furnace if the ignition of gas is delayed.

A variety of issues can delay the combustion of that gas. So the gas builds up in the furnace until—BOOM—it ignites, causing a mini-explosion. This can harm the heat exchanger, which is very expensive part to replace. Some causes of delayed ignition includes:

1. Dirty burners
2. Flames are lifting away from the burner outlet due to too much primary air
3. Too much gas

If you're handy enough to understand what I've said then burners can be cleaned/replaced, and primary air can be adjusted. With some units gas flow can be adjusted as well; other times the gas valve will need to be replaced.

If you've no idea what I've described, GET HELP before you ruin the heat exchanger and have a more expensive problem on your hands or worse...

SOURCE: Kozy World propane wall heater

The ceramic "bricks" need to be heated evenly. Since 3 are good, I would have to assume the other two have a restriction. Maybe a spider in the orifices, If  you can access the "jet" where gas comes out, try using a paper clip or something similar to clear any blockage. If that wont do it, pull the burner, remove each orifice and clear. Good Luck

SOURCE: Is there a way to convert a kozy world KWN313

Your model is not listed at http://www.kozyheat.com/.

If this is currently a natural gas fitted device, there is a better than not chance it can be converted.

Please check with the manufacturer or dealer where you purchased the device. You can also contact your local propane supplier who would do the actual converting of the orifices.

A note: If this device is presently set up for natural gas and is hooked up, and you still have natural gas available, this is normally the cheaper of the two fuels to use.

Thanks for your quesiton at FixYa.com

SOURCE: I have three Kozy World wall heaters. Two work

Yes, it sounds like the third heater has a Control Valve problem. It's allowing more gas into the system than what it's supposed too. Have you tried turning the flames down to a lower setting? If so, did it lower the flame height? How old is this heater and is cleaned and serviced at least annually? Are you using Natural Gas or Propane?

Please get back to me with the answers to the above questions and I may can help you.

Thanks,
Rich

If you have a standing pilot that wont stay lit and you have to keep relighting it, it can only be a couple of things that will do this.
1. Try tighting the thermocouple at the gas valve. (this is a thin copper line that goes from the gas valve and goes to the pilot light.)
2. Make sure that the tip of the thermocouple is in the pilot light flame.
3. Make sure that the thermocouple is clean.

Pilot flame pops and gets llonger then shorter


From what you have described, it sounds like a pressure problem with the gas. Contact Kozy World (you can find their home page on line) and speak with their Tech Service Dept. Also, the gas in the tank pay be very low.

You need to clean it out. Take the wall heater down and use a air compressor to clean out the gas system. Also clean the orifice out. Make sure that the chamber is clean and clear of spider webs and dust.
