What not to do to a gas valve

Unknown

There have recently been several posts here on the Wall about the gas valve not opening. The posts went on to say or someone gave them this solution. BANG THE GAS VALVE WITH A HAMMER. I am here to tell you that if the gas valve will not open then change the gas valve. It is never a very good idea to BANG A GAS VALVE. The truth is that you could cause damage internally to the valve and then it will not shut off. It will be stuck open mecahnically. You then better hope all the boiler safeties work, and think about this what kind of safety do you have on a warm air furnace after the limit is out of the picture?

Nathan what was the letter

after the Smart Valve number, if it was not a M or a P it should not be used in cold places only M & P rated for -40 degrees up to 175 (F). All other valves only good for "0" to 175. You need to make sure as it will fail again. The difference is the material that the valve seats are made of.
