In Turkey today, with the increase in availability of natural gas, detached heating devices are being preferred over existing heating devices. Due to the lack of chimneys in existing buildings in Turkey or the presence of chimneys that fail to conform to standards, the use of C-type balanced chimney devices has increased. C-type balanced chimney devices take the combustion air directly from the outside by a specific air duct as detached heating equipment, with enclosed combustion chambers and a specific waste gas exhaust duct, and they are ventilated independently of the field of equipment. Because of their essentiality, the use of a chimney is not required in these devices; the waste gas is exhausted through walls, windows, doors, or balconies. The natural gas is a clean fossil fuel that requires no storage in buildings and is easy to use. However, water vapor, carbon dioxide and nitrogen oxides are produced by the combustion of natural gas. It is widely known that high concentrations of these products can have some adverse effects on humans such as dizziness, headaches and nausea. As a result, the waste products could recoil through wall openings on the fa�ade to create unhealthy indoor environments that could be dangerous to human health. Therefore, the importance of standards and regulations about the positional arrangements of the waste gas exhaust ducts of C-type balanced chimney devices on building fa�ades is increasing. In this research, we analyze the studies of the Institution of Turkish Standards, Chamber of Mechanical Engineers, gas distribution companies, municipalities and authorized firms and compare the criteria to determine the necessary application method. According to our comparison of the references accessed, the criteria are not uniform.

Keywords: C-type balanced chimney devices; natural gas; hermetic systems.

G�n�m�zde T�rkiye�de do�al gaz kullan�m�n�n artmas� ile mevcut �s�tma ayg�tlar�n�n yerini ba��ms�z �s�tma ayg�tlar�na b�rakt�� g�r�lmektedir. T�rkiye�de mevcut yap�larda baca olmamas� ya da standartlara uygun olmayan hatal� bacalar�n bulunmas� nedeniyle ba��ms�z �s�tma sistemi olarak yanma i�in gerekli olan havay� kurulduklar� ortamdan ba��ms�z �zel hava ba�lant�s� ile d�� ortamdan alan, kapal� yanma odal�, yanma �r�nlerini �zel at�k gaz bile�enleri ile d�� ortama veren ve havaland�rmalar� bulunduklar� ortamdan ba��ms�z olan, C tipi denge bacal� ayg�tlar�n kullan�m�nda art�� g�r�lmektedir. Bu ayg�tlarda bacaya gereksinim duyulmad�� i�in at�k gaz ��k�� d�� duvarlardan, duvar bo�luklar�ndan ve balkonlardan yap�lmaktad�r. Do�al gaz, binada depolama gereksinimi olmayan, kullan�m� kolay ve temiz bir fosil yak�tt�r. Ancak, do�al gaz�n yak�lmas� sonucunda ortaya su buhar� ile birlikte karbondioksit ve azot oksitler ��kmaktad�r. Bu gazlar�n y�ksek yo�unlu�unun insanlar �zerinde ba� d�nmesi, ba� a�r�s�, mide bulant�s� gibi olumsuz etkileri oldu�u bilinmektedir. At�k gazlar�n cephedeki duvar bo�luklar�ndan i�eri girerek bina i�inde insan sa�l�� a��s�ndan tehlikeli ortamlar olu�turmas� s�z konusu olabilir. Bu nedenle C tipi denge bacal� ayg�tlar�n at�k gaz ��k�� borular�n�n bina d�� cephelerindeki yerlerinin d�zenlenmesiyle ilgili kurallar �nem kazanmaktad�r. Bununla ilgili olarak �al��mada T�rk Standardlar� Enstit�s�, Makina M�hendisleri Odas�, gaz da��t�m �irketleri, belediyeler ve yetkili firmalar�n �al��malar� incelenerek, do�ru uygulaman�n yap�labilmesi i�in kaynaklardaki �l��tlerin kar��la�t�r�lmas� yap�lm�� ve bu kar��la�t�rma sonucunda kaynaklarda yer alan �l��tlerin birbirleri ile uygun olmad�� g�r�lm��t�r.

Anahtar Kelimeler: C tipi denge bacal� ayg�tlar; do�al gaz; hermetik sistemler.
