It's hard to beat gas heat for sheer convenience. A HearthStone gas-fired stove is an efficient heating unit. A HearthStone gas stove is equipped with a pilot light (a constant flame used to ignite the main burner) and requires no household current for operation, even during a power outage. If the pilot light goes out, a safety switch shuts off the gas supply. Re-lighting the pilot light can be easy.
For nonelectronic ignitions, which are usually gas-fired stoves manufactured before 1990, turn off the gas at the main valve found in the utility box. Allow 5 to 10 minutes for gas in the air to dissipate. This will prevent any hazardous situations while working with flammable gas. After setting the furnace valve to "pilot," press the red pilot button while holding a lit fireplace match to the pilot valve. By pressing the red button for 30 to 60 seconds, the pilot can heat the thermocouple. (A thermocouple produces a voltage related to a temperature difference.) Release the button and see if the pilot remains lit. If the pilot goes out, allow another 5 to 10 minutes before attempting the procedure again to clear any unused gas. Once the pilot stays lit, turn the main gas valve back on.
Some HearthStone gas stoves are equipped with an electronic ignition. ProFlame is a popular brand of HearthStone stove that is furnished with an electronic ignition. The way the ProFlame ignition works is simple: The pilot is off when the stove isn't running, resulting in ample fuel savings--a great way to save money and the environment. Plus, with a battery backup, heat will still be provided during power outages. The most common types of electronic pilot systems are: Intermittent pilot system--When the thermostat calls for heat, it uses an electronically controlled high voltage electrical spark to ignite the gas pilot and the main burners. Hot surface ignition system--when the thermostat calls for heat, it uses an electronically controlled resistance heating element to ignite the gas burner.
There are many issues that can contribute to a pilot light going out on an electronic ignition. Faulty pilot burners, faulty control modules, faulty pilot gas valves, and a damaged spark electrode could be among the many culprits affecting pilot light outages. Breathing in gas and handling electrical wires can be dangerous. Proper ventilation is important when in the presence of gas. Unless the owner of the gas stove is familiar with electronic ignitions and gas systems, it is best to contact a licensed professional.
