The process is simple consist of smoke producing tablet air blower and air passing channe.
Duct smoke test procedure.
The duct smoke testing process 1.
A larger meter for example q 26δ p could test 666 s f.
The basic idea behind using a duct leakage tester to test for duct leakage is.
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.
This smoke test finds out the leaked area in the hvac duct system.
Use a calibrated fan to pressurize the duct system.
Of duct 64 9 6 100 with 6 δ p.
All dampers if installed to.
All boots are temporarily sealed by either the ac contractor or authorized smoke testing personnel.
Yes if the duct detector cannot be reset at the facp or annunciator then a separate test reset station will need to be installed for resetting the duct detector per nfpa 72 section 23 8 5 4 6 4.
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.
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.
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.
Test proceduretest procedure 1 select duct section for testing 2 measure and calculate duct surface area 3 pg p seal all openings except one.
Test apparatustest apparatus duct leakage test system consists of duct leakage test system consists of.
3 1 notify the facility work coordinator using the approved electronic work control notification procedure.
Hvac smoke testing with superior smoke smoke testing effectively and inexpensively reveals leaks and other faults in heat ing and air conditioning duct work.
Ac representative is present during.
