Firstly, when connecting with a large-diameter hose, ensure that the threaded section of the reducer and stove connector is fully inserted into the large-diameter hose. Secure it with wire ties or pipe clamps to prevent it from falling off. Be careful not to over-tighten the wire ties to avoid damaging the large-diameter hose.

Next, large-diameter rubber hoses should be inspected regularly, particularly at the two joints and bend areas. If softening, hardening, brittleness, cracks, or leaks are found, cut off that section. If the large-diameter rubber hose is still long enough, it can be connected and continued to be used; otherwise, it should be replaced. If the aforementioned issues arise in the middle of a large-diameter rubber hose, it should be replaced with a new one promptly.
