There are many requirements for the installation of ventilation pipe systems. Let's briefly discuss them.
For duct connections, a tight fit is required; the thickness of the gasket used should not be less than 3mm. The gasket should not protrude into the duct or extend beyond the flange. Strict installation requirements must be followed for metallic ducts during turns. When bending plastic flexible hoses, dead bends or collapses should be avoided.
Prior to the installation of air ducts, all interior and exterior debris should be cleared, and thorough cleaning and protective measures should be taken. Additionally, the positioning of screws in the duct's connection sections should be as convenient as possible for future maintenance.
