I finally got an answer out of King County yesterday morning on installing the T6 a bit closer than 7.5" to my ventilated brick wall - still leaving more than 7.5" to combustibles - YES, OK. Helpful note to others;
*Pay $160 for the permit, then call 206-296-6600 and explain you have a pre-installation question for the inspector. They got back to me next day (I left voicemail and followup email with details/photo.)
* Do not bother: emailing [email protected] - never got an answer, and do not bother posting the question on their website - you'll get an answer, but it will be completely useless. At least in my case
Unfortunately, with all the time that lapsed - PE apparently put through a big price increase on May 28th - putting the T6 at ~ $1100 more than a pre-increase T5 I was able to buy yesterday. I was pretty bummed to say the least, to go from the high of the yes to be able to install the T6, to the no-go due to the price increase.
Anyway, hope the above info helps someone else.
