The Insufficiencies of the International Building Code (ICC) & The Residential Code Council (IRC)
The International Code Council (ICC) sites two codes concerning the exhaust system for bathrooms exhaust fans; Code Council (ICC) Chapter 15: Exhaust Systems Section M1501 GENERAL.
The air removed by every mechanical exhaust system shall be discharged to the outdoors in accordance with Section M1506.2. Air shall not be exhausted into an attic, soffit, ridge vent or crawl space (ref. 2).
Section M1507.2 MECHANICAL VENTILATION; Recirculation of air. Exhaust air from bathrooms and toilet rooms shall not be recirculated within a residence or to another dwelling unit and shall be exhausted directly to the outdoors. Exhaust air from bathrooms and toilet rooms shall not discharge into an attic, crawl space, or other areas inside the building (ref. 2).
The Soffit Vent invention was to target the loop holes under the International Code Council (ICC) and the Residential Code Council (IRC).
Soffit vents are not regulated by the Building Codes. For the past 40 years all of the soffit vents sold on the market used for the termination for the bathroom exhaust fan instead of solving a problem are the cause of the problem. Each year homeowners spend billions of dollars on mold remediation and the repairs for the damage. This does not take into account the billions spent on contamination caused by the inadequate soffit vents. The only solution the Building Codes came up with was the creation of the Remediation Companies that has become a billion dollar industry.
Details On Installing The Soffit Vent
When the Soffit Vent is in place the Soffit Vent has 6 screw holes on both sides of the housing. The two front placements for the screws at the front will fall directly in then center of the exterior 2 x 4 of the frame work of the soffit overhand. The normal placement of the rafters is 16 inches on center.
When placing the Soffit Vent between the rafters the center of the neck of the Soffit Vent should be 2 1/4 inch away from the inside of the rafter. One of the two sides will fall in the center of one of the rafters of the soffit. The side screw holes can be used to an additional attached and depending which rafter is being used the screw place will fall directly in the center of the rafter.
On the nose of the Soffit Vent there is a bevel. This is designed to compensate for the normal overhang of the facia that extends down past the soffit. In some case it could be more. If the fascia is more than 1/2 it will be required to cut off the excess wood so that the bottom of the fascia sets on the Soffit Vent and flush against the soffit.
The Soffit Vent must be level without a pitch and the top sided of the Soffit Vent is tight against the soffit. In other cases the bottom of the facia can be flush with the overhand of the soffit. This is not a problem but what is important is that the bevel must be directly beneath the interior side of the fascia.
The Neck of the Soffit Vent
The neck of the Soffit Vent is the part that extends into the soffit between the rafters. The is the part where the ductwork of the extension tube of the exhaust fan is attached to the Soffit Vent. In the image of the sider view of the Soffit Vent it shows the beveled nose and the center of the neck of the Soffit Vent. The angle of the bevel is placed up against the interior side of the fascia and then you measure back 4 3/4 inches toward the house. The neck of the Soffit Vent a radius of 1.72 in or a circumference of 3.7 inches. The center is 1.85 in.
This is where you mark the spot and then using a hole saw cut out 4 1/2 inch hole. This will give you the room for the pulling the extension tube of the ductwork from inside the soffit and attach it to the neck of the Soffit Vent.
Attention: don’t forget to take into consideration the space needed from the inside of the rafter so that one side lines up with the center of placement of the two screws on the side of the housing. Once the correct placement is determined then attach the extension tube of the exhaust fan to the Soffit Vent. Once the attachment is completed (follow the guidelines in the (Installation page Step #3) push the excess ductwork back inside the soffit making sure the ductwork is not crimped obstructing the airflow of the exhaust fan. Put a bead of silicone around the base of the neck of the Soffit Vent to seal the opening of the soffit with the neck. It is recommended to use a silicone that remain flexible and for exterior use.
The neck has a height of 1 3/4 in. This takes into consideration of the thickness of the wood soffit of 1/4 to 3/8 in leaving a minimum of 1 1/4 to attach extension tube.
The Soffit Vent by Moisture Flow® is manufactured with a High Impact Polystyrene designed to withstand the sub zero temperatures of the North American and the elevated temperatures of the tropics.
The Soffit Vent can also be used for the new High Efficiency Gas Water Heaters. For the details for HVAC/Plumbing Contractors write to info@moistureflow.com Attention: Tom/Commercial Accounts in the subject line
