Abstract
A gas fireplace air intake filter comprises a releasably detachable non-combustible air filter; releasably detachable to a front opening of the air intake; wherein the air filter is a strip of porous, fibrous, non-combustible scouring material with strips of hook-type fasteners mounted around the front opening of the air intake, the hook-type fasteners being one half of conventional hook-and-loop type fasteners, which releasably adhere to the scouring material.

GAS FIREPLACE AIR INTARE FILTER
Field of the Invention The present invention relates to the field of gas fireplaces and in particular to air filters for such fireplaces for fitment onto gas fireplace air intakes.
Background of the Invention Applicant has observed that lint, dust, pet hair, or the like are drawn through the air intake grill which on conventional gas fireplaces in situated on the front surface of a gas fireplace, that is, the surface facing into the room in which the fireplace is situate. On such fireplaces, the air intake grill typically extends horizontally across the width of the fireplace adjacent the floor of the room. The debris being drawn through the air intake grill results in electrical shorting-out of the electrical connections on, for example, the on/off switch for the fireplace. It has been observed that on any of the wiring harness attached on the underside of the gas fireplace, that shorting out due to the accumulation of debris is a common occurrence.
Applicant is aware of United States Patent No.

2,269,387 which issued on January 6, 1942 to Weaver for an invention entitled "Furnace". Weaver discloses a self-contained unit installed for operation, either permanently or temporarily, in a fireplace, the unit providing for air entry through an intake having a screened opening in the lower portion of the front of the unit. Mounted in the intake is a filter through which the ingoing air must pass. An electrically driven blower draws air into the air intake duct through the air intake grill and filter so that air passing through the filter is cleaned.
The air filter is illustrated as being oblong in shape and fitted within the air intake duct beneath the gas burner. The composi-tion of the air filter and the method by which the filter is mounted within the air intake duct is not disclosed.
Summary of the Invention It has been found that air filters generally of the type disclosed by Weaver must be highly heat-resistant in order to be safely used beneath a gas burner in a conventional gas fireplace. It has also been found that it is beneficial that the air filter be easily removed from the gas fireplace either for cleaning or replacement, and that the air filter must be mounted sufficiently securely so that it will not become dislodged and be drawn into the air intake duct by the air flow generated by, for example, an electric blower. It is thus advantageous that the air filter be easily detachable for cleaning or replacement so as not to discourage cleaning or replacement by a household user. A clogged air filter may impede the operation of the furnace and decrease the life of the electric blower.
The gas fireplace air intake filter of the present invention is thus both releasably detachable and non-combustible.
In particular, the air filter of the present invention is a strip of porous, fibrous, non-combustible scouring material such as ScotchbriteTM scouring material which may be releasably mounted across the front opening of a fireplace air intake.
A strip of hook-type fasteners, such as VelcroTM
fasteners, may be mounted around the periphery of the front opening of the fireplace air intake across which the air filter is to be mounted so that the hook-type fasteners releasably adhere to the fibrous scouring material.

Figure 2 is a cross sectional view along line 2-2 in figure 1.
Figure 3 is a detailed view of the segment of figure 2 denoted by the numberal 3.
Figure 4 is a front elevation view of the gas fireplace of Figure 1 with the front grill and filter of the present invention removed.
Figure 5 is a front elevation view of the gas fireplace of figure 1 with the front grill removed and the filter of the present invention installed.
Detailed Description of the Preferred Embodiment Figure 1 illustrates a gas fireplace 10. Fireplace 10 has front face 12 including front grill 14. When fireplace 10 is installed, front face 12 faces into the room in which it is installed. As illustrated in Figure 2, within fireplace 10 is gas burner 16 which exhausts through exhaust flume 18.
Air is drawn through front grill 14, passes through filter 20, and is either drawn along duct 22 by convection heating of air in duct 22 or by operation of electric blower 24.
Air which has passed through air duct 22 is exhausted from front face 12 into the room from under hood 26. Electric blower 24 is shown in more detail in Figure 3.
Figure 4 illustrates front face 12 with front grill 14 removed. Gas burner wiring harness 16a, igniter and on/off switch 16b, and control valve 16c are exposed. Front grill 14 may, alternatively, be hinged so as to rotate out of the way when open. VelcroTM strips of hook material 23 (for fastening to strips of loop material) may be installed around the periphery of the front opening 22a of air duct 22 exposed by opening or removing front grill 14. As illustrated in Figure 5, filter 20 may then be installed across front opening 22a of air duct 22 exposed when front grill 14 is open. Filter 20 is a strip of ScotchbriteTM scouring material or other non-combustible, porous, fibrous scouring material.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifica-tions are possible in the practice of this invention without departing from the spirit or scope thereof. Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims.
