Remember that a screen for the fireplace is both decorative and useful for the fireplace so it is necessary to examine the screen that you are going to purchase has a good quality but still economical. It may be best to consider the traditional and modern looks when choosing a fireplace screen. You have to make sure that the fireplace screen you choose has decorative and protective features. Before buying a screen for your fireplace, it is essential to know certain details about your fireplace. You should know about the measurements of your fireplace in order to know the dimension of the screen you need. A fireplace screen made of wrought iron can give your fireplace an attractive design.
The benefit to a ventless gas log fireplace outdoors is convenience and cost. The process of building proper ventilation and a chimney can often double the expense of custom fireplaces indoors or outside. Convenience is the ability to create a perfect flame pattern as easily as turning on a barbeque grill. Many gas log fireplaces have complex valve options that allow variable remote controls that alter flame height, on/off remotes, wall switches and thermostatic controllers that turn the fireplace on and off based on the temperature read at the thermostat. I do not recommend any of these valves in your backyard. A manual safety pilot kit has a standing pilot light that stays on always. As long as the pilot is burning, the fireplace can be controlled with a simple control knob. A couple of decorative ceramic pinecones or wood chunks hide the controls. Remotes, wall switches, thermostatic controls and other valves use batteries. Even a gas log fireplace that is under an overhang will be affected by moisture in the air. Here in Florida where humidity is tremendous, a battery operated valve will corrode within a year in most backyards.
Outdoors a ventless gas log cannot deplete oxygen or fill your home with gas but a different set of issues ensues. Oxygen Sensors can get pollen and dust in them and wind can confuse the pilot assembly’s ability to provide continuous heat to the thermocouple. The design of the fireplace and the placement of the logs should be discussed with a professional to minimize these possibilities. These issues do not risk the safety of your family but if the thermocouple thinks the pilot is out because the wind is directing the flame in another direction, your gas log burner will turn itself off. An experienced installer will manipulate the mounting bracket to work around wind issues and position the Oxygen Depletion Sensors so they do not get clogged with pollen and dust.
Ventless gas logs are designed to be used indoors and have several safety features that make them safe inside your home. Manufacturers of ventless gas logs have a limit to the amount of BTU’s burned which limits the size of most unvented gas log burners to 30". The size of a firebox that would comfortably hold a 30" gas burner is 42" to 48" which is still a large fireplace. A standing pilot assembly stays lit and heat is tracked with a thermocouple. If the flames go out for any reason, the thermocouple cools and gas stops at the valve. Oxygen depletion sensors are also attached to the gas valve to ensure the flames do not burn up so much oxygen in the house that unsafe conditions are created.
