A linear fireplace system, assemblies, modular units, and related methods that can be installed in a modular fashion at a selected installation location so as to avoid drawbacks experienced in the prior art. The system can include modular linear units, corner units, and/or end units interconnectable to form a modular linear fireplace assembly. The system can include an alignment track system with a track member that receives alignment rails on the bottom of the modular units to axially align the interconnected units. The system can include a combustion air flow passage within the fireplace that maintains a relatively low exterior temperature of the assembly and that allows combustible and non-combustible building materials to be installed against or immediately adjacent to the top and base portions of the modular units of the assembly.

The present invention discloses a streamer type flame simulation device, which includes a casing, some cross-flow fans disposed inside the casing, a first streamer, a second streamer, a supplementary air-supplying device and a light source. The supplementary air-supplying device is arranged in the split joint area between the two cross-flow fans. In the present invention, since a supplementary air-supplying device is provided between two cross-flow fans for supplying air, the deficiency where air was unable to deliver at the space occupied by the drive motor of the cross-flow fans can be avoided. Various parts of the first streamer and the second streamer can be blown, thus preventing the flame from being cut off and enhancing the overall coordination, which greatly improves the viewing effect of the flame area.

An artificial log assembly includes an artificial log having an outer wall that is substantially cylindrical and elongated along an axis. The artificial log has a cavity inside the outer wall. The artificial log assembly includes a fuel supply in the cavity. The fuel supply has a plurality of fuel outlets closer to the axis than to the outer wall. The fuel outlets are spaced from each other along the axis. Slits extend through the outer wall to the cavity. At least some of the slits are spaced from each other along the axis and are spaced from each other circumferentially about the axis.

A system including a burner configured to be coupled to a fuel line to deliver fuel to the burner and an igniter positioned adjacent to the burner and configured to ignite fuel emitted by the burner. The system further includes a valve configured to control a flow of fuel through the fuel line and a control module operably coupled to the igniter and to the valve. The control module is configured to send a signal to the igniter and to close the valve if a quality of a return electrical signal from the igniter is below a predetermined value.

Provided is a flame simulating device including a light source, at least one light-transmitting rotator and an imaging plate, and the light source emits a first light group; the light-transmitting rotators are arranged in a light path of the first light group in a rotatable manner, each of the light-transmitting rotators is provided with multiple light concentrating blocks, these multiple light concentrating blocks convert the first light group into a second light group; and the imaging plate is fixedly arranged in a light path of the second light group.

A fireplace and method of manufacturing a fireplace. Embodiments of the fireplace comprise a combustion chamber, a front opening allowing viewing within the combustion chamber, and a back wall opposite the front opening. The back wall can be controllably switched between an opaque state and a transparent state. A combustion region between the front opening and the back wall is adapted to provide a flame. A controller coupled to the back wall enables a user to switch the back wall between the opaque and transparent states. In embodiments the back wall comprises a glass panel and switchable film on the glass panel. The controller is coupled to the switchable film.

An exhaust and air intake system for a direct vent fireplace. A low-profile manifold assembly is coupled to a direct vent fireplace and is configured to receive exhaust gases from the fireplace and expel the exhaust gases outside of the building in which the fireplace is located. The manifold assembly also takes in fresh air from outside of the building and provides the fresh air to the fireplace to use during combustion. The manifold assembly includes separate chambers for the exhaust gases and the fresh air so that the exhaust gases and the fresh air do not mix together within the manifold assembly. Several pressure reduction and equalization structures are incorporated into the manifold assembly to regulate the amount and pressure of fresh air provided to the fireplace.
