Leak Check The Purpose of the leak check is to locate the major leaks in the enclosure before performing the door fan test. Often large holes are located that must then be sealed before the door fan test can begin. Sometimes the smoke test identifies dampers that are not closing correctly or not at all.
Smoke test & measure static pressure The purpose of this test is to see whether there is a static pressure in the room prior to the door fan test. The door fan is not running and smoke is puffed in front of an open hole in the blower.
Select Blower Range Principles of Infiltrometer Air Flow Measurement The Infiltrometer can accurately measure airflow between 18 CFM and 6500 CFM. However, in order to measure accurately over this wide range, the range must be changed as described in the following section. The Infiltrometer fan blade pushes air out the back of the fan creating a negative pressure in front of the blades.
Range Selection Procedure Always start with the restrictor plate off - that's called Range 22 for the 22" diameter inlet. Give the speed control a quick half turn to get the motor moving then QUICKLY turn the control DOWN if required. As you increase the fan speed, the Room Pressure gauge will rise.
Flow Range Diagram Always start in the Flow Away position. Adjust speed till room pressure is reached. Fan must be running at least at half speed and flow pressure must be greater than room pressure. If not, insert the Range A plate and keep changing to lower ranges till motor is at least half speed and flow pressure must be greater than room pressure.
Range C1 - Flow Away Range A - Flow Towards. The inlet is now on the other side. Look at “Flow Away” picture to see what the inlet must look like. Range C8 - Flow Towards. The inlet is now on the other side.
Room and Flow Pressure Readings Make sure the blower is running at half speed or more before taking any readings. Analog Gauge Readings ...from the Magnehelic gauges from the Model E Analog Gauge Clip Tubing Connections: For the 60-gauge- connect the red tube from the upper port through the panel. When the blower is reversed, the red tube must be connected to the lower port.
60 gauge readings Read the upper scale only. Reverse the tubes when you turn the fan around to test in the other direction. Taking Readings from Two Blowers If one blower can't get adequate Room Pressure, remove the upper panel cover and install a second blower.
Digital Gauge Readings Model DM-1 Digital Gauge Tips Re-Zero … prior to taking a new set of readings. Changes in temperature or position may affect the zero by 0.1 to 0.4 Pa but overall the drift will be minor. It is best not to re-zero before a test is completed. Take readings for both pressurize and depressurize without re-zeroing the DM-1.
1.Turn ON the DM-1. Wait 30 seconds. Set first toggle to “ZERO” 4. When this light is lit, all connections have been made at blower and it’s ready to go. Turn on the power to blower #1. 2000 Fire Door-Fan Manual 2.
Two blowers for large rooms, (see also section on flex-duct testing) Use the second control cord for blower #2. Install while the blower is on the ground, and then install the blower in the panel. Complete steps 1 to 3 on the previous page first. Then go to step 7. 7.
Windy Conditions If the gauges fluctuate more than 1 Pa due to wind, follow these steps to reduce the fluctuations in the gauge reading. Tip: instead of taking readings at low room pressures around 10 Pa, perform the test at 60 Pa room pressure.
Use averaging on digital gauge to reduce the effect of wind. 2000 Fire Door-Fan Manual Set the Time averaging to 5 seconds. If the second reading varies more than 10% from the first reading, set it to 10 seconds. If the variation is still too much, set it to 30 seconds.
Deluxe Wind Damping System to Stop Gauge Needles Moving If the room pressure gauge fluctuates more than 1 Pa due to the wind and the standard two tube damping system does not reduce them sufficiently then the optional wind damping system may be more effective.
Mixing or No Mixing (Descending Interface) or Extended Discharge Mixing means that as agent leaks out the incoming air is continually mixed with the remaining agent in the room so that the concentration is constant throughout. Mixing gives equal protection to all levels in the enclosure.
If the room fails Equipment calibration is often blamed for these failures but in over 12 years of 500 companies testing, it has never been a factor. It is usually that he room leaks too much. Airsealing looks simple but should be left to Weatherization contractors; NOT general contractors who may think they can do it but seldom can.
This will only help if there is continual mixing during the retention period. If the air- handlers are shut off at discharge, more agent will give less retention time. Rooms with suspended ceilings will double the retention time usually when agent is discharge above the ceiling for mixing and no mixing cases.
Flex duct installation for ceiling neutralization Position the flex-duct case under the ceiling tile in which it will be installed and open the case. There must be minimal obstructions to airflow above and around the ceiling tile selected. . Hook the cuff under the lower foot of the blower and over the nylon block on top of the blower flange.
A ceiling tile is removed to allow the flex duct to be mounted The upper blower is measuring lower room leaks whilst the lower blower neutralizes leaks above the ceiling. 2000 Fire Door-Fan Manual Note how the flex-duct mounts in one half the tile opening whilst the Retrotec blanking sheet that comes with the flex duct fills the rest of the space previously occupied by the ceiling tile.
Lower leak tests using: Plastic-on-Ceiling procedure This procedure is much more time consuming than using the flex duct. It consists of measuring the Lower Leaks by covering the ceiling with plastic. This takes a lot of time but does give good results particularly in small rooms. A temporary solid barrier to leakage through a suspended ceiling can be used instead of the neutral pressure used in the B-2.6.2 "Flex Duct"...
The principal deviation from the normal procedure is that the test can only be conducted in one direction, i.e. as a pressurization test. Depressurizing almost inevitably pulls down the plastic. In a room without a suspended ceiling, plastic could be used to seal off undampered ducts at ceiling level to better determine how much of the room leakage is below ceiling level.
Lower leak Estimates using: Leak audit Set the door fan to produce a 15 Pa positive pressure. Open the door panel up to witness smoke moving at “full speed”. Locate enclosure leaks, measure the open area. Test the leak with smoke in the area where the leak was measured. Mark down the % of full speed that each leak appears to be.
Field calibration check with calibration plate Place the second Blower Panel on top the first Blower Panel and expand into position. Place the X-Y Panel on top the Blower Panel. Panels installed with upper panel cover with calibration holes ready for performing the field calibration test.
The Field Calibration Check is a procedure which enables the AHJ to determine that the door fan to be used on a test is sufficiently accurate, and that the technician knows how to operate the equipment. It is also a useful training exercise for an inexperienced operator gaining familiarity with the equipment.

Recalibration of Retrotec Infiltrometer The NFPA Appendix C requires recalibration of only the room pressure gauge every year. Ask Retrotec for an exchange 60 Pa. gauge and be sure to specify whether the tubes go out the back for the model 870 “kickstand model “...
Retrotec Gauge and System Calibration All Retrotec Gauges are calibrated against a Master Reference Calibrator (MRC) that has an accuracy of +/-0.1 Pa or 0.1 %. The concept Retrotec equipment uses is that all of Retrotec’s products are now calibrated against the same reference. When a blower is built, it is calibrated against the MRC for pressure and an ASTM flow chamber for holes.
For a complete calibration, take the gauge up to full scale, hold it there for 60 seconds, release the pressure and zero the gauge. Apply positive pressures to the upper port and a negative pressure to the lower port such that changes in atmospheric pressure will not affect the calibration.
Retrotec gauge calibration software was developed especially for meeting NFPA and ISO requirements. Page 49 of 58 2000 Fire Door-Fan Manual updated 2002-05-28...

Possible Mechanical Problems Panels Will Not Fit Doorway Try using an alternate doorway. If doorway is too large, use a 2" x 4" or a 2" x 3" block against the side of the panels, or panel width extenders to 48" (available from Retrotec). If the flow element rubs against the wall, door, or any other obstruction, try turning the panels upside down or contacting panels with another part of the door frame.
for leaks in the gauges by blowing in the tube, then folding the tube over on itself - the gauge should hold pressure without the needle dropping perceptibly. Occasionally, a needle will get stuck to the face plate. Replacing the gauge is the only practical option. Gauge Needle Falls When Tested Each time the Infiltrometer is used, the gauges should be pressured up, the tube capped off to test for leaks.
Thermometer Replacement If the thermometer does not read correctly and cannot be adjusted with the control on front of the console, the entire assembly is removable and can be replaced by the operator. Call Retrotec. Fan Makes Scraping Noise When Turning Check to see if the blade hits the screen or the edge of the white plastic tube.
