消防安全消防排煙風(feng)機(ji)的理相部(bu)位應晝(zhou)靠近屋脊線，定位時(shi)，將防水基(ji)板(ban)(ban)閑置在平屋面(mian)(mian)上(shang)，并使基(ji)板(ban)(ban)上(shang)傾的邊(bian)緣端置入房脊金屬材料(liao)后(hou)蓋(gai)板(ban)(ban)下的間(jian)隙里約(yue)熱(re)內盧10厘米.以防水基(ji)板(ban)(ban)的內螺紋為樣版，繪制洞邊(bian)的中心線，然后(hou)用平屋面(mian)(mian)自動(dong)切割(ge)機(ji)完成洞邊(bian)的激(ji)光(guang)切割(ge)。并整修(xiu)打(da)磨(mo)拋光(guang)邊(bian)緣。用鋒利的刀頭將保(bao)(bao)溫(wen)棉(mian)按米字(zi)型(xing)劃(hua)破(po)，拿掉部(bu)分保(bao)(bao)溫(wen)棉(mian)后(hou)，再將保(bao)(bao)溫(wen)棉(mian)跟鋁鉑塞入厚鋼板(ban)(ban)跟保(bao)(bao)溫(wen)棉(mian)中間(jian)。

在防(fang)(fang)水(shui)湛板(ban)跟(gen)房脊后蓋板(ban)的相接處(chu)貼上防(fang)(fang)水(shui)平衡(heng)膠(jiao)泥帶。在兩(liang)側的波峰焊頂端，貼上防(fang)(fang)水(shui)平衡(heng)膠(jiao)泥帶，并在管接頭跟(gen)彩(cai)鋼瓦中間打上防(fang)(fang)水(shui)硅橡(xiang)膠(jiao)，撕下頂層(ceng)廢紙箱。用(yong)少10個(ge)自攻螺釘(ding)釘(ding)或抽(chou)芯鉚(liu)釘(ding)將防(fang)(fang)水(shui)基板(ban)固(gu)定不動在平屋面上。

將變(bian)角管(guan)頸(jing)(jing)安裝(zhuang)在基(ji)板上，旋(xuan)轉(zhuan)變(bian)角管(guan)頸(jing)(jing)可轉(zhuan)動部(bu)分，根據水準(zhun)儀開展相背九十度角的(de)調濟，促使變(bian)角管(guan)頸(jing)(jing)的(de)上邊水準(zhun)。調濟完畢后用彩筆將變(bian)角管(guan)頸(jing)(jing)的(de)高矮旋(xuan)轉(zhuan)部(bu)分及變(bian)角管(guan)頸(jing)(jing)與基(ji)板中間(jian)畫線標記(ji)。

用(yong)(yong)少四顆自攻螺絲(si)，將(jiang)(jiang)變角管頸固(gu)(gu)定(ding)不動(dong)在基板(ban)。用(yong)(yong)金屬材料(liao)夾片(pian)跟(gen)鋁抽芯鉚釘，將(jiang)(jiang)變用(yong)(yong)管頸高矮(ai)兩(liang)旋轉(zhuan)部(bu)分固(gu)(gu)定(ding)不動(dong)在一起實際操(cao)作(zuo)的另外請留(liu)心兩(liang)端對齊(qi)原先(xian)的畫線標記。將(jiang)(jiang)渦輪增壓頭的四個支撐點臂卡入預埋在管溝中，再用(yong)(yong)四顆螺釘將(jiang)(jiang)渦輪增壓頭固(gu)(gu)定(ding)不動(dong)在變角管頸上(shang)。
