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.
I have been in this situation many times and the answer is often gas logs. I have had clients with damage to their chimney flue inside a wall and believe they can put a gas log fireplace kit into their wood-burning fireplace instead of repairing the damaged flue. This is a mistake, and a dangerous mistake. Gas logs use liquid propane or natural gas instead of wood for fuel. When gas burns, oxygen is burned and carbon monoxide is created. If there is damage to the flue, a typical gas log fireplace is not the answer because the fresh air ventilation is still necessary to pull out carbon monoxide. The answer is ventless gas logs. Vent free gas logs do not have to be vented. When a client wants to design a custom outdoor fireplace but they do not want to build a chimney and cut through their patio roof, a vented gas log kit is the perfect solution because no ventilation is necessary.
