How do i install a thermal coupler for forced air heater gas

wile red button is pushed no flame or turns off when the button is released the flame dies ? if no flame tank is too small or spark isn't in far enough to catch gas . if flame is present with button down then the over heat switch on the in line thermal coupler could b bad u can check the over heat switch with a jumper between the two wires and if it stays lit you got it if it goes out then its the thermal coupler that's bad

Most gas water heater problems can be solved by cleaning burner parts and combustion chamber, and bleeding air out of gas line, checking gas pressure, and making sure gas shut-off handle is turned-on and parallel with gas line:
Many things cause pilot light to go out including dirty parts, air in gas line, and hot-unventilated atmosphere.

the thermal coupler could be bad. try and hold the gas button down for about 15 to 20 seconds and see if the flame will stay on after that amount of time when button is released. if it still goes out - then replace the coupling with a new one and all should be good after that.

No you can not convert this unit to natural gas. They do not make a conversion kit or give us any sizes to drill out any orifices.

Sounds like you may have to replace the thermal coupler. check your local hardware store for a replacement for your model.

Time to get a new tank. The life expectancy is between 10-15 years. You are probably spending more in natural gas to heat than the tank is worth.

could be the milivolt generator was adjusted too far in the flame causing the tip to burn out. all it has to do is detect the flame not be in the flame path!.

Merry Lynn, there will be no physical differences between Natural Gas heaters and Propane Gas heaters. Check the model number of the unit, it may have a N or P or LP printed at the end of it to distinguish which gas it uses. The plate that is attached to the heater should indicate the type of gas it uses.

 

DO NOT try to convert this heater to another gas.
