The Installation from hell http://www.thepelletstovedoctor.com/Site/Bridge_St._Repair.html These are a series of pictures I took to provide to a property manager I often work for. Initially this job was a pelletstove cleaning but as soon as I remove the 90 degree elbow off the back of the stove the pipe seperated within the chimney and came crashing down. I figured the pipe simple came apart because perhaps the installer failed to mechanically attach one section to the other and simply glued or taped them together. I suggested to the property manager that I replace the 90 degree elbow with a clean-out tee with cap and connect the pipe sections mechanically. When I got out to the jobsite with the Tee and started removing the pipe here is what I found. I am scheduled to return to the jobsite and install a new venting system. I will take some more pictures and post them here. July, 7th, 2008 Today I replaced the 4” venting and changed out the 90 degree elbow with a clean-out tee. The job went very well and all the sections fit together without any problem. I stopped at an auto supply place and picked up some higher heat RTV sealant than I typically use because the pipe is uninsulated singlewall stainless steel. I used 4 stainless steel rivets per connection to connect the sections of pipe together. I used RTV at each joint and down the seam of each section of pipe and covered all the rivet heads. I did this job solo so there are no pictures of me packing the pipe up onto the roof and dropping it down the flue and onto the waiting tee. I RTV’d the base of the pipe for a good seal at the tee and wrapped the connection with aluminum tape. All the sections laid out for all to see. http://www.thepelletstovedoctor.com/Site/Bridge_St._Repair.html#0 acdc2b54-7554-460d-868f-7f95ef386268 http://www.thepelletstovedoctor.com/Site/Bridge_St._Repair_files/Media/IMG_5211.jpg?derivative=thumb http://www.thepelletstovedoctor.com/Site/Bridge_St._Repair_files/Media/IMG_5211.jpg?derivative=micro <div style="padding: 0px; " class="image_cluster_layout_style_default_External_515_113"><div class="image_cluster_layout_style_default"><p style="padding-bottom: 0pt; padding-top: 0pt; " class="Caption">All the sections laid out for all to see.</p></div></div> I guess the original installer figured to save a buck by using galvinized pipe and hiding it in the trunk of the fireplace. By the way, there was no bottom sealing plate in the fireplace so any leaking carbon monoxide settled near the stoves room air fan and was blown out into the room. http://www.thepelletstovedoctor.com/Site/Bridge_St._Repair.html#1 ff1e6867-642e-46b3-aa39-07211f8d900f http://www.thepelletstovedoctor.com/Site/Bridge_St._Repair_files/Media/IMG_5201.jpg?derivative=thumb http://www.thepelletstovedoctor.com/Site/Bridge_St._Repair_files/Media/IMG_5201.jpg?derivative=micro <div style="padding: 0px; " class="image_cluster_layout_style_default_External_515_113"><div class="image_cluster_layout_style_default"><p style="padding-bottom: 0pt; padding-top: 0pt; " class="Caption">I guess the original installer figured to save a buck by using galvinized pipe and hiding it in the trunk of the fireplace.
