Duct smoke test procedure. This smoke test finds out the leaked area in the hvac duct system. Assuming that the duct leaked at class 3 and the test apparatus could generate the static pressure to indicate 24 cfm 250 square feet of duct 24 9 6 100 250 could be tested at one time. Allow one week for approval of the requested work and be prepared to reschedule the requested work to satisfy the areas production schedule. All boots are temporarily sealed by either the ac contractor or authorized smoke testing personnel.
The sound of the actuator and the time it takes are tantamount to a test. Measure the airflow through the fan with the duct system at pressure. 3 1 notify the facility work coordinator using the approved electronic work control notification procedure. Test apparatustest apparatus duct leakage test system consists of duct leakage test system consists of.
This test will be performed annually on each duct smoke detector. 1 blower with speed control vfd to generate range of pressure flowrange of pressure flow. The superior method of generating smoke by chemical reaction eliminates costly equipment and time consuming operations in pinpointing hvac leaks. The process is simple consist of smoke producing tablet air blower and air passing channe.
Hvac smoke testing with superior smoke smoke testing effectively and inexpensively reveals leaks and other faults in heat ing and air conditioning duct work. Use a calibrated fan to pressurize the duct system. Smoke detectors must be tested yearly and when they are released the actuator of the smoke or combination fire and smoke damper will spring closed or for smoke dampers that must open spring open. Portable smoke tester is connected to the supply and return sections of the duct work.
All dampers if installed to. Ac representative is present during. The duct smoke testing process 1. A larger meter for example q 26δ p could test 666 s f.
