We purchased the Regency model P121-NG2 dual-sided fireplace based on how great the fire looked in the brochure. Based on our experience, it makes one wonder if the brochure had some PhotoShop work done to create an image of a fire that is nothing like what we have. Fireplace looks great and is a show piece in our home ... so long as you don't turn it on. The flame height is so, so low that it is a challenge at times to see it other than the glowing fake embers. Extremely disappointing to see such a large fireplace with a flame height similar to a campfire moments before it dies for the evening. We have had many professionals knowledgeable about gas fireplaces (HVAC technicians (2), gas supplier, and two mechanical engineers) look at ours and after checking absolutely everything other than the fireplace itself, they have all concluded that the gas regulator/valve within the fireplace is faulty. Regency, unfortunately, has a so-called "expert" technician who seems to think that the problem all has to do with log placement and arrogantly thinks everyone else are idiots (hence Regency has no interest to solve the problem). Clearly, the Regency tech must have cut his technical certificate from the back of a cereal box because he is absolutely clueless when it comes to technical conversation with others (especially engineers who are orders higher in technical capability ... they're the one's who design the fireplaces and train the techs). So if you want after-sale tech support, don't buy from Regency as their tech are idiots!
