One needs to make sure you get complete pictures of the entire system from above AND from below including both sides of fan blades. the filter trough for the entire length, and behind the upper filter rails including the connection of the bottom of the riser from the hood. You MUST make sure the picture are not taken at angles that avoids areas. Make sure that the pictures show all sides of the duct and that subsequent pictures show all areas. In the following, the KEC vendor has been fooling the FM for years. They have been sending pictures regularly and what is sent looks good. Here is an example of pictures showing only the clean areas and what the job really looks like with all areas shown. I see this often from both the large national vendors who make a practice of decipt and from even the smaller vendors. Once must be very proactive careful, and diligent on what they are looking at. It is best to have your own pictures to compare to. (Baseline pictures) You need to also look at the places with your own eyes at least every 12-18 months depending on concept and grease volume.
Here are the pictures looking down from the roof where
everything appears to be clean.
And looking into the fan in the next two pictures, all
looks well and very clean.
And looking up the stack on one system does
not look bad.
However, when we start looking closer
at the Main systems from below.......
You can see clearly where the scrape marks stopped from
the roof area on one system
And in the hood, the behind the filters have old thick
buildup right above where there is the best chance
of a fire
And in the other main system, you can clearly
see where the scraping stops when the
picture was taken looking up from the hood.
These are the biggest fire danger areas!!
Even the fan blades have old burnt on buildup. Both of
the main fans were shaking badly. Here is why!!
