I have a propane wall mount heater and the pilite light stays lite but when you turn it up to kick on the burner lights and will stay lite for a few seconds and kicks off and the pilite light goes out too. Any suggestions on how to fix it, It is only 2 months old. our heater won't stay lit - we hear a click right before it goes out.
