New kozy world natural gas heater. Pilot light wont stay lit snd heater flame wont stay lit.


Are you holding down the pilot light button long enough for the heat sensor probe to get hot and turn on the gas valve? It takes up to 3 minutes

Thinking about buying a pro com -ML250TPA-BB from tractor supply for my garage can i use a 40 lbs. propane tank for gas supply?


I think what you have is a 100 Lb tank, that holds 40 gallons of propane. If that's,the case, it would be acceptable. IF the tank is placed Outside the garage 3 ft from any doors or windows: The gas line is a minimum of 1/2" diameter; the heater is permanently mounted to the wall (at least 18" off the floor); there is an accessible, inline gas shutoff valve within 2 feet of the heater and you have a properly sized tank regulator. You do all that, and you'll reach the minimum code standards that are required.

Hope this helps you make the right decision.

I keep setting my thermostat but it automatically goes back to same temperature no matter what i set it at


If it is a programmable thermostat, it will only stay at a certain temp until it reaches it or on a set time, then it goes back to the scheduled program temperatures. Most programmable thermostats do have a hold feature that allows you to hold the temp to a certain setting, but if you don't set it to permanent hold, then it does what you described. Hopefully this helps some or guides you in the right direction. Good luck!

Hi there,

sounds like it has a faulty button. The "on" button on that model has a button on the front side which should hold the on button down after igniting. Check and make sure that it is there. I think it is a spring loaded button - maybe the spring has dis-lodged itself. If the button is faulty yhou can only replace it.

Hope this Helps

Wont stay lit


go to this site www dot desatech dot com. Here you'll find parts to repair your heater. a propane heater uses a millivolt generator to sense the flame. along it's cappilary are two push on spde connectors. these connect to the high limit temperature sensor which is mounted on the flame backplate of your heater. to see if it is the high limit shutting down your heater, jumper across the two spade connectors. if the heater stays on, this is your problem. if the flame still goes out, then the millivolt generator is shot.
