How to install double gas stoves?

When the double gas stove was just bought back, all the parts were disassembled. It is necessary to assemble the gas stove first, install the stove and the fire bracket together, install the battery, connect the rubber pipe with the air inlet, fasten it with the fastening hoop after plugging it in, and then connect the gas pipe with the gas for testing. The specific installation process is as follows: the new gas stove parts are wrapped in foam, and each part needs to be taken out. Install the stove and fire bracket, and then see a small cover behind the stove, which needs to be loaded with batteries. Install two batteries, corresponding to the positive and negative poles. Find the red rubber tube of the gas pipeline, and then see an air inlet on the back of the stove. Connect the rubber hose to the air inlet. After plugging, tighten it with a tightening hoop. Make sure there is no air leakage, otherwise it will leak in the future and air will enter, resulting in incomplete combustion. After that, install firearms and fire covers on the furnace ring. There are two protruding screws in the middle of the fire ring. Install the fire cover corresponding to the screw, and then there is the small black cover. You need to put this small cover on the gas cooker ring and the whole stove will be installed. It is also necessary to install a pressure relief valve and fasten it, otherwise air will enter, resulting in pressure change.
