I bought a Charmglow model #CGL250TE gas fireplace at a garage sale this weekend. It had never been used and therefore did not come with a hose or tank. There isn't a manual and I could not find one online. There is a sticker on the back that reads "This heater requires an external regulator to reduce the LP tank pressure to a maximum of 14 inch W.C.". I went and bought an LP tank, a high pressure hose with A 10-psi regulator that has a 3/8" flare swivel fitting (female). One problem is that the fireplace also has a 3/8" female fitting. I went back and bought a 3/8" flare union fitting. I see now that the fireplace fitting is not made specifically for a flared male end. I don't know if this matters or not. I have also read that there is a difference between a low pressure regulator and a high pressure regulator, so now i'm confused if I even have the right regulator. I know that I have to be careful with everything when working with gas. Please help if possible.
