Code Issues & Information
There are new forms after the 2009 Supplement. Find them on the DCA page linked.
The hot topic of the last few months has been the new 2007 Building codes with 2009 supplements. In particular there has been a change in the condenser tie down procedures. the new code has elimnated the old exception of #14 screws and now requires each job to be engineered. We have been working with the local jurisdictions to come up with an “Alternate method”. This would allow us to go back to the old way of tie-down. Check back and we will keep you up to date on this.
The new Florida Mechanical code has removed the exepmtion for ground mounted residential tie-downs. This leaves the building departments with no option but to ask for an engineered detail on how you will bolt down a condenser for residential units. We have been notified that the Seminole Building Department is asking for a raised seal engineered detail before a change-out permit will be issued. ACCA/ CF has been working to get this problem solved by submitting for a “Alternate Method Exemption”. We are still working with Seminole County to get this resolved.
To date we have learned that the some manufacturers have been working to get this problem solved with their own equipment and that Trane & York have succeeded and Lennox is close behind.
TRANE If you install Trane equipment and use their Extreme Condition Mounting Kit, your condenser will be engineered to resist 150 mph wind speed. The building department will only require that you provide them with a copy of the attached engineered letter. I would also keep a copy of the instructions on the job for inspections.
York If you install York equipment and use their “Hurricane Kit 1HK0101” your condenser will be engineered to resist 150 mph wind speed. The building department will only require that you provide them with a copy of the attached engineered installation instructions.
Lennox If you install Lennox equipment they have a Miami Tech clip available with approved engineering. The building department will only require that you provide them with a copy of the attached engineered installation instructions.
We will keep this site up to date with any new news.
If you have problems with any other jurisdictions, let us know.
