Yes, I'm with you on the 16" needing to be measured from the front of the unit. I have about 18" from the front of the fireplace right now, so I'll definitely need to add something, since the unit sticks out something like 7".
There's a different clearance requirement that I missed the first time through the manual which might cause me some trouble. I found this site: (broken link removed) which states that the min distance from the CL of the fireplace opening to combustible side trim is 28 7/16”. I think they get there by taking the 40 7/8” dimension on pg 6, dividing it by two, and adding it to the minimum distance to side facing (8”), that is provided on page 3 of the manual (in the table and the figure). My minimum distance to side facing would be about 23.5” (33”/2 + 7”). So my questions are:

- In the table on pg. 3, it says “1.5 in extension”. Does that mean that the 8" requirement only applies to side trim that extends 1.5" or more from the wall? If that is the case, I’m ok.
- If I am not ok… is there shielding I can buy for my side trim?
