I could not edit my original posting so have added to it by posting this followup. The reason that I thought that parts might be somewhat starndard is that I have seen plans for building your own splitter available on ebay etc. I have heard that this company either went out of business or was bought out by MTD. Hoses would not be a problem but any actuating valves or rams might be hard to replace. If so, it would probably be best to avoid a machine like this even if it is in good or excellent condition.

There are important ssafety hazards with vent free. And they are a violation in some building codes, especially if in a sleeping room. They can dangerously deplete the oxygen level in the room and can also produce combustion pollutants. The best most energy efficient system uses Direct Vent technology, but they are costly to buy and sometimes complicated to install. We have one and love it. An alternative gas log system that is vented and produces the most realistic flames that I have seen is made by Eiklor (?? the spelling). They will probably heat a room more than most vented gas log systems, but still send most of the heat up the chimney. Check their website. If you can manage it, get direct vent. Stay away from vent free.

If it's space you are concerned about, look into the Slim Line Series by H & G. The SL-750TRS is a good unit and the output is very much the same as the 6000 (other than the 6000GLX). The differance is in depth (viewing area size is the same at 36"), the 750 is 16 1/4" and the 6000's are 21 1/2" deep. You gain a little more floor space with 750, and you still get your Ceramic Glass. The new TR version of the 750 offers a Clean Face conversion, and though they come standard with Acrylic Glass, you can also upgrade that to the Ceramic and add a Brick Kit to have a similar look as the TRS, just a little less heat (24,300 max BTU output vs. 30,000+ w/ 6000/750TRS).

All the dealers around carry Peterson RealFyre - but this forum has several negative posts about them. I want to find some "realistic" looking 24" gas logs for my vented fireplace (we've been burning wood in it for the time being) that don't put off much heat (we're in Florida in a new home). I can't find the BTU detail on the Rasmussen logs - but maybe BTUs don't tell the whole story? How can I determine which logs are going to fit my needs?
