The conversion requires new jets in the unit and readjustment of the air /gas ratio shields. Use a qualified gas specialist for the conversion .

I have a problem with my Ruud LP heater. The gas valve is model VR8440M2024. Does anyone know what the M2024 means? I have found VR8440 valves on line but don't know if they will work with my unit....

The Robertshaw 720-079 is a universal type replacement valve. It comes with an LP conversion kit. You will probably come out better off using this than trying to locate the OEM part.

Is the front of the fuel powered heater supposed to glow red?

Hi, and the answer is yes. All fuel powered type heaters will glow red, or bright orange. Example, a space heater that runs on #2 fuel oil, natural gas, gas, kerosene, ect. will glow this way, so do not be alarmed. This is normal.
