Hello All. Thanks to the many fine recommendations on this site, I purchased the RSF Opel II. It is a lovely unit and I did the install myself. My roof is slightly steeper than a 7/12, so I originally went with an ICC 8/12 flashing. However, after climbing the ladder and laying it on the roof (after I had cut the hole, of course), it seemed much too steep and was leaning in toward the roof at quite an angle. ICC only sells variable pitch flashing and I only had the choice between a 1/12-7/12 flashing or an 8/12-12/12, so I returned and got the 1/12-7/12 flashing.
Due to the angle of the flashing, there is only between .75 to 1 inch clearance between the chimney and the lower part of the flashing (side closest to the eave.) Hopefully these pictures will illustrate. There is otherwise at least 2" to other combustibles such as sheathing as per requirements. It almost seems that if I got the 8/12-12/12 flashing, I would have the opposite problem and the chimney would sit to close to the ridge side of the flashing base. (Seems that I cannot find a happy medium.)
The interior view is that of chimney passing into 13" square hole in roof sheathing up through the flashing. The chimney is behind an interior chase, hence I did not use a radiation shield. I also included photo of flashing and storm collar on roof as another point of reference, as it seems a bit odd-looking. Also, I definitely regret using roofing tar to seal between flashing and roof as you can see by the goopy blotches in the first photo
Is the clearance between flashing and chimney a safety concern?
many thanks in advance!
