Gas heater

With gas heating stoves, two systems are used for the supply of the combustion air and the removal of the exhaust gases. Either the exhaust gases are fed to a chimney and the combustion air is taken from the room in which the stove is located is set up, or it will be, in the case of the external wall system, the Exhaust gases are passed through the outer wall directly into the open air, while the combustion air also comes directly from the open air dem'Gasheizofen or its burner is fed.

In the case of gas heating stoves with a chimney connection, a so-called Flow protection required, which ensures perfect combustion also in the event of malfunctions on or in the chimney

109887/0041

should perform if, for example, traffic jams or reverse currents occur Im In the event of a backflow, the exhaust gases escape from the flow safety device into the room in which the furnace is installed. The flow safety device, known per se, is usually a separately manufactured component which is connected to the exhaust gas nozzle of the gas heating stove, which requires more space in the depth, i.e. in the horizontal dimension between the front wall of the furnace and the wall of the room or building is conditioned. The exterior wall system is a good one Tightness of the combustion chamber required to avoid drafts to avoid inside the fresh air exhaust system in the event of wind, which would lead to the burner going out can.

The structural differences between the two systems of gas heating stoves are so great that it cannot be done without major adjustments is possible, one intended for chimney connection

Prepare gas heating stove so that it is suitable for connection to the outside wall is, and vice versa. The conversion has to be done anyway the flow protection can also be attached to an external wall oven.

The invention has for its object to provide a gas heating furnace that is simple and with only little assembly work of one connection system can be converted to the other system or adapted to the changed use, with no additional Space requirement for the flow protection occurs in the space between the gas heater and the building wall.

109887/0041

To achieve this object the invention is a gas heater, which is _p with the necessary for the outer wall terminal B uteilen equipped, according to configured such that an additional pipe socket is provided for chimney connection, and that provided in barren above the combustion chamber a known diverter .

It is advantageous to design the flow safety device so that it consists essentially of a TJ-shaped, with its legs upward-facing sheet metal, which rests against the front and rear walls of the combustion chamber with both ends is attached in such a way that the combustion gases flowing past the sheet metal below and to the side are limited from above into the U-shape Space.

The outlet opening belonging to the flow safety device is expediently housed in the front wall of the combustion chamber. A slide can be provided to close this outlet opening be.

In the drawing, an embodiment of the invention is shown shown Bs;

Fig. 1 shows a gas heater in section, connected to a chimney

2 shows the gas heating furnace illustrated in Mg. 1 after conversion connected to an outside wall and

Fig. 3 is a front view of the combustion chamber of the gas heating furnace 1 and 2 after removing the casing of the gas heating furnace.

The gas heating furnace has an essentially box-shaped combustion chamber 1 in which the gas burner 2 is located. At the Rear wall of the combustion chamber 1 sits the pipe socket 3> to which the exhaust pipe 4 is to be connected, through which the exhaust gases Chimney 5 are fed. Furthermore, on the rear wall of the combustion chamber 1 there is a channel 6 which runs vertically and the length of which corresponds to the height of the combustion chamber. At the upper end of the channel 6 sits the pipe socket 7, through which the Combustion air taken from the room in which the furnace is installed enters the gas heating furnace. At the bottom of the Channel 6, the combustion air flows through an opening 8 to the burner 2. The gas heater has a removable cover 12, through which the parts of the furnace including the fittings are encased.

A flow safety device is housed in the interior of the combustion chamber 1. It consists essentially of the approximately U-shaped

109887/0041

Sheet <7, which against the front wall and against the rear wall of the ^ Combustion chamber lies tightly at both ends so that there is an open top, roughly trough-shaped space. In the one from the sheet metal and the space limited to the front or rear wall of the combustion chamber 1 are baffles 16. The flow safety device becomes tton the heating gases, which, rising from below, flow past the legs of the U-shaped plate 9 after a part of the hot gases, is directed to the side on the underside of the flow safety device »These hot gases enter the flow safety device from above and from there reach the flue gas nozzle. So with Back-up or backflow an exit of exhaust gas or air from the Flow protection is possible, this has an opening Io which is made in the front wall of the combustion chamber 1. In Fig. 5 is through the diagonal in the rectangular opening Io and the Sirichelung indicated that it was a breach of the Wall acts. 11 is the slide with which the opening can be closed.

When the gas heater is connected to a chimney 5, as shown in Fig. 1, the opening Io is not covered, so that the exhaust gases can escape in the event of a stagnation and the air can be diverted in the event of a backflow.

With the outer wall connection of the gas heating furnace, which is illustrated in FIG the furnace shown in Fig. 1 is used after it has been prepared as follows:

109887/0041

The exhaust pipe 4 is pulled out of the pipe socket 3 on the rear wall of the combustion chamber. On the outer wall of the vertical Channel 6 is a pipe socket 7 »which has a larger cross-section than the pipe socket 3 on the rear wall of the Combustion chamber 1. In the pipe socket 7 is a known fresh air exhaust pipe 13 inserted or attached in another way, which by a horizontally lying web 14 approximately in the Middle is divided. The upper half of the cross section of the Frisehluft exhaust pipe 13 surrounds the exhaust pipe 3 and is used to discharge the exhaust gases. The combustion air flows through the lower half of the cross section of the fresh air exhaust pipe 13 from the outside of the building and reaches burner 2 through channel 6. The opening Io must be connected to the outside wall be closed by the slide 11 or in some other way, e.g. by a lockable flap.

With both types of connection, the heater can be mounted directly in front of the wall with the smallest possible distance. Of the Space requirement is -al · »« in the depth, i.e. in the dimension between Front wall of the casing of the gas stove and the building wall, very low.
