The support assembly is configured to support one or more burners. For example, the support assembly may include a burner holder with a cutout region, which may allow a burner to be moved between an operational position and a disengaging position by twisting the burner. The cutout region can allow the one or more burners to be removed or installed relatively easily, without the need of removing the manifold from the support assembly. The manifold can be attached to the support assembly by, for example, using one or more orifices as fasteners. ## Claims ### Claim 1 A burner system, comprising: a supporting assembly; a manifold; and at least one burner, the supporting assembly includes a burner holder; and a locking member connected to the burner holder, the burner holder has at least one cutout region configured to accommodate the at least one burner, the at least one cutout region has an opening, a first indentation configured to receive a first part of the burner, and a second indentation configured to receive a second part of the burner, wherein the first indentation is opposite to the second indentation of the at least one cutout region, the at least one burner has an operational position and a disengaging position, when the burner is in the operational position, the first part of the burner is configured to engage the first indentation and the second part of the burner is configured to engage the second indentation, and when the burner is in the disengaging position, the first part of the burner has a first clearance with respect to the first indentation and the second part of the burner has a second clearance with respect to the second indentation, and the locking member is configured to close the opening and lock the at least one burner into the operational position, the burner holder is configured such that when the burner is twisted in a first direction with respect to the burner holder, the first indentation engages the first part of the burner and then the second indentation engages the second part of the burner, and the burner holder is configured such that when the burner is twisted in a second direction with respect to the burner holder, the second clearance of the second part of the burner with respect to the second indentation is formed and then the first clearance of the first part of the burner with respect to the first indentation is formed. ### Claim 2 (depends on 1) The burner system of claim 1, further comprising: an orifice; wherein the support assembly is attached to the manifold by the orifice, and the at least one burner is removable without dissembling the manifold from the support assembly. ### Claim 3 (depends on 1) The burner system of claim 1, wherein the at least one of the first and second indentations has an angled portion configured so that when the at least one burner is twisted from the operational position to the disengaging position, the at least one burner is removable due to the first and second clearances. ### Claim 4 (depends on 1) The burner system of claim 1, wherein the burner holder includes a plurality of cutout regions, where neighboring cutout regions have the first and second indentations respectively mirrored to each other. ### Claim 5 (depends on 1) The burner system of claim 1, wherein the at least one burner includes a notch that engages the burner holder. ### Claim 6 (depends on 1) The burner system of claim 1, wherein the support assembly includes a base portion and forms a cartridge structure with the burner holder. ### Claim 7 A burner system, comprising: a supporting assembly; a manifold; and at least one burner, the supporting assembly includes a burner holder; and a locking member connected to the burner holder, the burner holder has at least one cutout region configured to accommodate the at least one burner, the at least one cutout region has an opening, a first indentation extending from the cutout into the burner holder, and a second indentation extending from the cutout into the burner holder, wherein the first indentation is opposite to the second indentation of the cutout, the at least one burner has an operational position and a disengaging position, when the burner is in the operational position, the burner is configured to engage the first indentation and the second indentation, and when the burner is in the disengaging position, the burner has a first clearance with respect to the first indentation and a second clearance with respect to the second indentation, and the locking member is configured to close the opening and lock the at least one burner into the operational position, the burner holder is configured such that when the burner is twisted in a first direction with respect to the burner holder, the first indentation engages a first part of the burner then and the second indentation engages a second part of the burner, and the burner holder is configured such that when the burner is twisted in a second direction with respect to the burner holder, the second clearance of the second part of the burner with respect to the second indentation is formed and then the first clearance of the first part of the burner with respect to the first indentation is formed. ### Claim 8 (depends on 7) The burner system of claim 7, further comprising: an orifice; wherein the support assembly is attached to the manifold by the orifice, and the at least one burner is removable without dissembling the manifold from the support assembly. ### Claim 9 (depends on 7) The burner system of claim 7, wherein the at least one of the first and second indentations has an angled portion configured so that when the at least one burner is twisted from the operational position to the disengaging position, the at least one burner is removable due to the first and second clearances. ### Claim 10 (depends on 7) The burner system of claim 7, wherein the burner holder includes a plurality of cutout regions, where neighboring cutout regions have the first and second indentations respectively mirrored to each other. ### Claim 11 (depends on 7) The burner system of claim 7, wherein the at least one burner includes a notch that engages the burner holder. ### Claim 12 (depends on 7) The burner system of claim 7, wherein the support assembly includes a base portion and forms a cartridge structure with the burner holder.
