Cleaning gas fireplace Sunwood Marino

Notes on care, cleaning and maintenance as well as in case of problems during operation (flame does not stay on):

The fact that the gas fireplace does not light or does not stay lit sometimes happens after it has not been used for a long time (spring). When the device is not in use, it is recommended that you switch it on briefly every 6 weeks to "burn off" any dirt. Furthermore, when changing bottles or after a long period of non-use, there is air in the gas hose, so it may have to be ignited more often.

If the device does not stay on or cannot be started, there is most likely dust from the lava stones or, for example, a dead insect in the flame distributor. You should first check whether there is enough gas (propane) in the bottle and whether it is turned on. The gas pressure reducer should be mounted horizontally (writing facing upwards) on the bottle. In rare cases (after a long time) it can happen that the gas pressure reducer does not let through any or not enough gas due to a defect or contamination. This can be replaced easily and cheaply.

The gas pressure reducer should be replaced every 8-10 years after manufacture (date on pressure reducer) or if damaged / leaking.

The gas hose should be replaced every 5 years after manufacture (date on hose) or if damaged / leaking; at the latest, however, after 8 years (max. 10 years).

The device (gas hose, connections, etc.) should be checked regularly (e.g. when changing bottles, when not in use for a long time, etc.) for leaks. A so-called leak spray is available from gas retailers for this purpose.

Explanation of the components:

If you look from above into the small, square ignition box next to the burn bowl/lava stones, there is an angled silver plate with a small slot on the right-hand side (2 metal plates on top of each other, the upper silver metal plate has a "nose"). This is where the ignition flame is directed to the middle temperature sensor (rounded knitting needle head) and forwards towards the burn bowl. If this flame distributor is blocked, the otherwise small blue flame cannot heat the temperature sensor and the fireplace does not stay on. It is also possible that only a yellow flame is visible instead of a blue one, which does not generate enough heat for the temperature sensor. The temperature sensor is a safety flame monitor that stops the gas supply if there is too little heat (flame has gone out).


• Please loosen the two screws on the cover and lift it down.

• Now push one or more panes upwards (preferably with 2 people) so that you have access to the fire bowl.

• As a first step, you can try to cover the lava stones with a piece of cardboard and carefully vacuum the flame distributor.

• Then test the fireplace with the lid open and the panes removed. Always allow it to cool down again first.

• We recommend removing the lava stones completely and carefully cleaning the fire bowl etc. with a vacuum cleaner and a damp cloth.

• Instead of using a vacuum cleaner, the best results are achieved by "blowing" into the flame distributor with a compressed air spray (hardware store) in order to remove all foreign objects with a little more pressure. The compressed air spray usually comes with a "straw" with which you can blow into the flame distributor. To do this, insert/hold the straw into/on the "nose" of the above-mentioned silver plate of the flame distributor and "blow in" with several strong blows. ATTENTION: Operate the can with the compressed air spray as vertically as possible and not upside down, otherwise the propellant will escape directly. (If necessary, remove the burner for this purpose) The propellant is usually flammable and must be completely evaporated before the gas fireplace is lit. This process can also be repeated, with tests in between (always allow the device to cool down first). Alternatively, you can carefully use a compressor with an appropriate pressure reducer (not at full power).

• You can also carefully try to clean the narrow gap between the two metal plates of the flame distributor using a brush. Please ensure that the metal parts are not bent and that no bristles etc. get stuck.

• Try to operate the fireplace regularly without the lid and panes from time to time.

• Once everything has been cleaned and the fireplace is working properly again, you can carefully place the lava stones (one at a time) into the fire bowl. Do not pour them, as they always create a little dust. Then reinsert the disc(s) and put the lid back on top and screw it tight.

The above instructions should restore the fireplace to normal operation.
