✔ 最佳答案
Do you buy this gas stove from Town Gas? They provide regular service. Mine is uses battery. The benefit is you don't have to connect electricity supply (safe installation cost) but yoiu have to change battery for a period of time (say approx. every 18 months).
If you can't find the qualified technician, you can call Town Gas service hotline and seek advice.
But most of all, you must pay attention to what kind of gas stove you bought, is it certified by HK govenment, if so, there should be a label of 'GU' fixed on the stove. Otherwise, you must ask Town Gas to check whether it is acceptable and safe to us in HK.
