I am in need of a NG 24v gas valve for a Desa P325EB B-Vent fireplace that is only a few years old, but am told that it is an old valve and may be hard to get. In the Desa owner's manual it is part number 14569 - Electronic Gas Valve (NG). It seems like a pretty standard valve, but Desa is no longer fielding Tech Support calls. With anyone familiar with these valves, it has the EV1 and EV2 solenoid terminals that open the pilot and main valves. Is there a way to get this same valve from a distributor, or is there a replacement valve that I can use (like Robertshaw or something)?
