What should I look for in a natural gas fireplaces?

The first thing would be checking that it’s EPA certified, meaning that it meets special standards set in place by the government when it comes to clean burning and safety overall. Next would be checking what type of heating capacity you’ll need since they come in many different sizes ranging from smaller models around 16 inches tall all the way up to larger ones which can reach over 60 inches depending on your needs (the larger one usually has more BTU power and output). The last thing is just simply making sure that this unit will look good enough for whatever area you plan on putting it into because let’s face it, not everyone wants a huge fire pit taking up most of their living room space without having too!
