A gas fireplace insert for inserting into existing solid fuel fireplaces is made into modules that are separable for installation and can be later assembled together. A housing module which includes a combustion chamber supports a separable module comprising a duct for fresh air intake. The duct includes a connection collar for an air intake pipe leading to the interior of the duct. The duct also has a pass through collar for carrying exhaust gases from the fireplace. The collars can be attached to an exhaust pipe and air intake pipe respective, which extend through the existing chimney. The duct module is separated from the housing module for installation so that the pipe connections are easier to make with the lighter, smaller module. Once the pipes are connected to the respective collars, the gas fireplace housing module is inserted into the existing fireplace opening and the air intake duct module is attached to the fireplace housing with openings in the housing aligning with and can be sealed relative to the exhaust pipe connection collar and with the opening in the air intake duct.
A module gas fireplace insert for inserting into an existing solid fuel burning fireplace having an existing solid fuel burning fireplace chimney comprising a housing for forming a combustion chamber having walls including a rear wall and an upper wall, the rear wall having an air inlet opening therein and the upper wall having an exhaust outlet opening therein;
A method of installing a gas fireplace insert in an existing solid fuel burning fireplace opening having an existing solid fuel burning fireplace chimney, wherein the insert has at least two modules including an intake air duct module and a burner housing module, including providing an exhaust opening from the burner housing in a first wall and a fresh air intake opening into the combustion chamber in a second wall and separated from the exhaust opening, securing two separate pipes to the existing chimney at an upper end of the existing and extending the separate pipes into the existing fireplace opening, placing the intake air duct module in the existing fireplace opening when separated from the housing, connecting the pipes to separate couplers mounted on the intake air duct module while the intake air duct module is separated from the burner housing module and inside the existing fireplace opening, installing the burner housing module into the existing fireplace opening, positioning the air intake duct module on the burner housing module inside the existing fireplace opening with one coupler aligning with and sealed relative to a perimeter of the exhaust opening in the burner housing module, the intake air duct module having an opening positioned to align with the intake air opening in the housing, and securing the intake air duct module to the burner housing module while inside the existing fireplace opening.
