Blower Door Operation Manual

1. digital gauge A gauge with an electronic pressure sensor and digital display that is capable of reading in tenths of a Pascal DOOF TAN A test instrument that fits into an open doorway in order to pressurize or depressurize an enclosure It isa calibrated fan capable of measuring air flow and is used while mounting it into a doorway A Door Fan is often called a Blower Door or an Infiltrometer Door fan is more linguistically correct than the common term blower door since it is not a door but rather a fan and since it does not use a blower Door Panel A solid or flexible panel used to temporarily seal off a door way while allowing for the installation of a fan for the purpose of blowing air into the building in order to measure the air leakage rate or to provide a pressure to assist in the location of air leaks Effective Leakage Area EfLA A common term used to describe air flow at a pressure by equating it to an equivalent size hole in an elliptical nozzle that would pass the same air flow at the same test pressure It is usually taken at 4 Pa and incorporates a 1 0 discharge coefficient It is typically about half the size of an equivalent leakage area that describes the same air flow rate See ASTM E779 10 eq 5 EfLA See Effective Leakage Area Page 85 of 87 Retrotec Inc 2015 A room house or building For rooms or interior spaces the enclosure is the surface bounding a v

Pilot setting It is possible for flames to be sucked out of a combustion air inlet flame rollout during a test which is a fire hazard and can result in high carbon monoxide levels If there are attached spaces e g townhouses that could contain a vented combustion appliance either adjust those appliances to prevent them from turning on during the test or be sure that the attached spaces are not depressurized or pressurized when the Door Fan is operating If combustion safety problems are found tenants and building owners should be notified immediately and steps taken to correct the problem including notifying a professional heating contractor if basic remedial actions are not available Remember the presence of elevated levels of carbon monoxide in ambient building air or in combustion products is a potentially life threatening situation Air sealing work should not be undertaken until existing combustion safety problems are resolved or unless air sealing is itself being used as a remedial action Failure to follow these instructions carefully may result in bodily injury damage to property and equipment failure Page 8 of 87 Retrotec Inc 2015 1 How the Blower Door System components work A Door Fan is a specially designed calibrated fan which as part of the Blower Door Fan System is temporarily mounted in a doorway The fan is used to blow air into or out of a room house or building to measure the air leakage of the enclos

13. Compensating for Panel leakage Modular Panels are designed to be placed into doors that are not well sealed The panel leakage for the Modular Panel is about 14 square inches compared to about 3 square inches for the Aluminum Frame and Cloth and around 1 square inch of leakage for the upgraded Aluminum Frame with snap together corners These three panels represent three typical doorways a Poorly weather stripped which would have an approximate 1 16 inch gap which equals about 14 square inches leakage b A well weather stripped and adjusted door would be around 3 square inches or leakage c A super tight door could be as tight as 1 square inch of leakage and can even have less One rule of thumb is that all standards require the blower door panel to be leakier and never tighter than the existing door The Modular Panel qualifies here Itis likely that the Aluminum Frame and Cloth are tighter than the existing door In either case if the door panel leakage is 10 of the total then further investigation is needed Panel leakage will vary from one installation to another as will the door leakage If you want to make an adjustment to a test result make these measurements at your reference pressure Page 32 of 87 Retrotec Inc 2015 Install the panel in a doorway where the door can be closed with the door fan panel in place then measure the leakage This is the Test Panel Leakage Door Leakage Now tape over the door so it does not leak at

Range configuration so that the Fan Pressure is twice or more the desired test pressure in the enclosure Testing should always be done with the most restrictive Range Configuration on the fan as possible for the following reasons 1 Accuracy increases as Fan Pressure increases 2 High Fan Pressure results in high fan speed which aids in cooling the fan 3 When conducting multi point tests starting with a restrictive Range Configuration eliminates the need to change the Range Configuration during the test Note In European countries where a 50 Hz power system is used Range Configuration selection becomes more critical because the fans will run 20 slower Therefore there is not as much difference between minimum and maximum flow on any given Range Configuration 4 9 Determine which Range to use on a Door Fan 1 Attach Range Ring A and B 2 Setthe gauge to Range Configuration B 3 Adjust the fan speed until the desired Room Pressure is reached If using the DM 2 digital gauge 4 If TOO LOW is shown on Channel B of the DM 2 attach the C8 Range Plate Restrict the flow further until the gauge is able to measure a pressure 5 Press Range Config until the correct Range Config is displayed on the DM 2 screen 4 Ifthe desired Room Pressure cannot be reached take Range Plates or Range Rings off 5 Press Range Config until the correct Range Config is displayed on the DM 2 screen If using analog gauges 4 S

108. ure The term room house or building is often shortened to enclosure The Door Fan System works by establishing a pressure difference between the inside and the outside of an enclosure The pressure difference forces air to leak through all of the holes in the exterior envelope of the enclosure The amount of air flow that is required to maintain a constant pressure difference is equal to the amount of air that is leaking from the enclosure A specially designed gauge can thus be used to measure the pressure difference and calculate the amount of air flowing through the Door Fan which can then be used to determine the total size of all those leaks A typical Door Fan or Door Fan system is comprised of four main parts A Door Panel which temporarily seals a typical doorway and provides a hole to mount a fan A calibrated fan capable of creating a measurable flow of air A two channel differential pressure gauge that can also calculate flow for a particular fan pu oe qm de A fan speed controller to change the air flow through the fan which can be provided by the gauge A typical Door Fan system breaks down as shown in Figure 1 Figure 1 The breakdown of a typical Door Fan system In this case an aluminum frame holds a Cloth Door Panel in place sealing the doorway The fan is mounted in the hole in the cloth and is supported by the aluminum frame crossbar The gauge is acting as both the fan controller and different
