Duct Smoke Test Procedure

Test apparatustest apparatus duct leakage test system consists of duct leakage test system consists of.

Duct smoke test procedure.

Test proceduretest procedure 1 select duct section for testing 2 measure and calculate duct surface area 3 pg p seal all openings except one. 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. This test will be performed annually on each duct smoke detector.

All boots are temporarily sealed by either the ac contractor or authorized smoke testing personnel. 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. 1 blower with speed control vfd to generate range of pressure flowrange of pressure flow. Ac representative is present during.

Allow one week for approval of the requested work and be prepared to reschedule the requested work to satisfy the areas production schedule. This smoke test finds out the leaked area in the hvac duct system. Use a calibrated fan to pressurize the duct system. A larger meter for example q 26δ p could test 666 s f.

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. The basic idea behind using a duct leakage tester to test for duct leakage is. All dampers if installed to. 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.

Of duct 64 9 6 100 with 6 δ p. The duct smoke testing process 1. The superior method of generating smoke by chemical reaction eliminates costly equipment and time consuming operations in pinpointing hvac leaks. Measure the airflow through the fan with the duct system at pressure.
