Abstract
A means for avoiding the build up of a film on the inside surface of the transparent window of a gas fireplace comprises providing a mesh screen spaced a short distance of the inside surface. The mesh screen is believed to interrupt the flow of gases toward the window thereby preventing the build up.
Description
TITLE OF INVENTION
SCREEN FOR GAS FIREPLACE WINDOW
FIELD OF THE INVENTION
This invention relates to gas-buming fireplaces. In particular, this invention reiates to a means of preventing the buildup of milky film on the inside of the io transparent front panel of a gas-buming fireplace.
BACKGROUND OF THE INVENTION
A common but persistent problem with gas-buming fireplaces is the buildup on is the inside surface of the front window of a milky or hazy film. The film detracts from the appearance of a fireplace and from the ability to appreciate the fire within.
While the cause of the film is not ciearly known, some manufacturers have 20 speculated that it is the result of the curing process of the paint and log sets used in the fireplaces. It has also been suggested that the white film deposit arises from additives used in the gas and reference has been made in industry literature to a mineral residue left from water vapor as the gas burns. Regardless of the cause, the film is perceived to be a problem and detrimental to the look of the 25 fireplace.
The present invention offers a solution to the film problem in gas fireplace windows.

Regardless of the cause, the film is perceived to be a problem and detrimental to the look of the 25 fireplace.
The present invention offers a solution to the film problem in gas fireplace windows.
SUMMARY OF THE INVENTION
The inventor has found that providing a mesh screen spaced a short distance from the inside surface of the transparent front panel of a gas-burning fireplace has the effect of preventing or alleviating the buildup of the film.
It is postuiated that the effectiveness of the invention is due to the interruption or modification of the air flow from the inside of the fireplace towards the inside surface of the panel. However, the preferred and other contemplated io embodiments are effective and the claims made herein are not dependent on a definitive understanding of why the invention works.
The foregoing was intended as a broad summary only. It was not intended to define the limits or requirements of the invention. Various aspects of the invention will be appreciated by reference to the detailed description of the preferred embodiment and to the claims.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will be described by reference to the detailed description of the preferred embodiment and to the drawings thereof In which:
Fig. 1 is an illustration of the undesirable white film on the window panel of a gas-buming fireplace;
Fig. 2 is a front view of the preferred embodiment of the invention;
Fig. 3 is a cross-section taken along line 3-3 of Fig. 2;

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Fig. I illustrates the milky white haze or film 10 that tends to build on the inside of is the window panel 12 of gas-buming fireplaces 14.
Figs. 2, 3, 4 and 6 illustrate the preferred embodiment of the invention.
According to the invention, a screen 16 is provided so as to substantially span the inside surface of the window panel 12 of the gas fireplace 14. As can be appreciated by reference to Fig. 4, the screen 16 is spaced from the inside surface 18 of the panel 12 by a short distance "d". The screen 16 lies in a plane 20 that is substantiafly parallel to the plane 22 of the panel 12 so that a reasonably consistent spacing d between the panel and the screen is maintained. In the preferred embodiment, the distance d is between % and 1 inch but may be as much as 8 inches.
Referring to Fig. 4, the screen 16 is secured by means of a bent portion 24 of the peripheral screen frame 26 that is seated in a gap 28 between the window -panel 12 and an inside shoulder 30 of the frame of the fireplace. It is contemplated that the screen can be made removable for replacement or cleaning if necessary.
Referring now to Fig. 5, the mesh size 40 of the screen 16 in the preferred embodfinent Is approximately'/ inch. However, it is contemplated that the mesh size will be effective between 1/16 and 318 of an inch.
In the preferred embodiment, the screen is made of steel wire cloth mesh but other materials that are capable of withstanding the environmental conditions in io the fireplace are likely to be equally effective, including notably Teflon -coated fiberglass.
The parameters of mesh size and spacing d that wiil be effective for the purposes of the invention wiii be dependent on the size of the fireplace, the distance of the burners and log sets from the front panel and the air and gas flows within the fireplace. These vary with different fireplace designs and conflgurafions, but the preferred embodiment and ranges discussed herein should be effective for the majority of commercial gas fireplaces on the market.
It will be appreciated by those skilled in the art that the preferred and alternative embodiments have been described in some detail but that certain modifications may be practiced without departing from the principles of the invention.
