窗戶(hu)(hu)(hu)排煙注意(yi)(yi)安全有(you)(you)些家庭為了避(bi)免(mian)串(chuan)煙問題，放(fang)棄原有(you)(you)煙道直(zhi)接在窗戶(hu)(hu)(hu)上開(kai)孔排煙。這樣做是可以(yi)的(de)，但有(you)(you)幾點需要(yao)注意(yi)(yi)：首先(xian)在窗戶(hu)(hu)(hu)或墻面開(kai)洞之前(qian)一定(ding)要(yao)經過物業的(de)同意(yi)(yi)；其次注意(yi)(yi)安全問題。一般(ban)排煙管(guan)(guan)(guan)末(mo)端是金(jin)屬(shu)材質的(de)，如果開(kai)的(de)洞太小，金(jin)屬(shu)傳熱可能會使玻璃炸裂(lie)傷及行(xing)人(ren)，且煙管(guan)(guan)(guan)通向(xiang)窗外強勁的(de)北風(feng)對著吹會導致油煙倒灌。建議將管(guan)(guan)(guan)道伸出(chu)去(qu)以(yi)后把管(guan)(guan)(guan)道往下(xia)窩，這樣還可以(yi)避(bi)免(mian)下(xia)雨時雨水(shui)流進管(guan)(guan)(guan)道，并把風(feng)擋在外面。
