Although, visibly they are very similar to the traditional fireplaces, in many ways they belong to the new generation. The innovations of modern technology has played very significant role in solving many of the hazards and problems attached with the forebears.
Construction
Previously, they were built with the help of mortar-and-brick masonry involving foundations and chimneys. Nowadays, they are based on the technology of zero-clearance. These are prefabricated units made up of metal.

They are designed in such a way that they can be installed in wood-frame construction. There is no need to construct a foundation. The biggest difference between these and any other is a chimney.
Because of their efficient burning, they are vented directly out a wall. That means these new direct vent gas fireplaces are much easier and inexpensive to install than the masonry units. Moreover, because of their prefabricated structure they enjoy greater flexibility in their placement.
Combustion Process
Direct vent fireplaces burn propane or natural gas instead of wood. Initially, conventional fireplaces were required a Class B ventilation pipe through-the-roof to vent away the byproducts of the combustion process.
However now, the present generation burn gases efficiently by using maximum heat from the combustion process thus exercising a much more efficient way of getting warmth. These units come with a securely sealed glass door which prevents leakage into the room.
The required air to support the flame is entered from outside, while the comparatively cooler gases from combustion process are thrown out through the vent. As these units are gas-fired, they counter the grave setback of wood-smoke pollution that grew to disaster many times about a decade ago.

Generally, these fireplaces come with passageways to assist the heat exchange. Some units have the option of fans to boost this circulation of heat throughout the room. 
Normally, you can achieve about 75% of the heat efficiency. The emission of heat by these gas fired units is measured by British thermal unit (Btu). The amount of heat needed to increase 1 pound of water through 1 degree Fahrenheit is known as 1 Btu.
While choosing the right kind of fireplace, you have to look for its output capacity which can tell you how much heat is generated. By getting the data of the input capacity and output capacity, you can derive its efficiency- the ratio of input to output capacity. In general, most of these units emit 25000 to 40000 Btu per hour.
Artificial Logs
Although, all gas fired units use artificial logs to burn, don't worry about the appearance of the flames. Yes, there were the days when these flames didn't appear as real. However, nowadays, all the models produce very authentic fire.

They come in many different designs like Standard (one-sided models), two-sided, peninsula models (three-sided), and island models (four-sided). They also come in the shapes of bay-window and corner units. Sizes do vary. 
While, their width ranges from 30 to 48 inches and height from 24 to 30 inches, they are typically quite shallow - depth ranging from 13 to 18 inches. They come up with both top and rear venting designs.
Controls
Controls vary from manufacturer to manufacturer. Some models have an electric spark ignition, to save energy, or a piezoelectric ignition. They also come with the option of a generator so that you can get the warmth even when there is no power supply. Remote controls have adjustable thermostats, blower speed controls, and facility of adjusting flame-heights.
