Brad NSW Posted February 14, 2018 Report Share Posted February 14, 2018 Any recommendations on how close a wood deck could safely come to the vertical exhaust stack? I'm trying to avoid any fire hazard! Any thoughts on heat shield material / asbestos to decrease clearance? 2010 Freightliner, DD15 Eaton Ultrashift, 2015 New Horizons 5th Wheel.

rickeieio Posted February 15, 2018 Report Share Posted February 15, 2018 One side of the brain says at least two inches. The other side sez the only time the exhaust gets hot is when there's plenty of airflow to blow the heat away. How's that for waffling?

noteven Posted February 15, 2018 Report Share Posted February 15, 2018 Could you design to have the stack fitted with a metal radiant heat sheild and space that 2” away from the wood? "Are we there yet?" asked no motorcycle rider, ever. Link to comment Share on other sites More sharing options...
Brad NSW Posted February 15, 2018 Author Report Share Posted February 15, 2018 Thanks RICKEIEIO, Understand the airflow logic...but if EGTs are 900-1100+ for extended time (pulling a long hill), that pipe seems like it would get pretty warm. Anyone have an EGT gauge. My guess, pulling these light loads we never push the engine to get really high EGTs for long periods. And by the time it gets that far back in the pipe, its cooled a bit too. NOTEVEN, I've got something similar on my Dodge just below the turbo to protect some wiring...seems to do the job. Anyone with a wooden deck close to the stack? Ever see any signs of charring? With lots of wind (O2), that seems like a recipe for ignition... 2010 Freightliner, DD15 Eaton Ultrashift, 2015 New Horizons 5th Wheel.

DesertMiner Posted February 15, 2018 Report Share Posted February 15, 2018 Do you have a newer truck that has to “regen”? If so...the temps may get pretty warm! Link to comment Share on other sites More sharing options...
Brad NSW Posted February 15, 2018 Author Report Share Posted February 15, 2018 Yes 2010. Didn't even think about that. Regen will be Worse than climbing a big hill. 2010 Freightliner, DD15 Eaton Ultrashift, 2015 New Horizons 5th Wheel.

ALLOY Posted February 15, 2018 Report Share Posted February 15, 2018 Try a search for "generator wall thimble" and look for images. You'll find lots of dimension. There are more than a few ways to do it depending on air circulation, heat shielding and insulation. I've used Roxul/Rocwool in the thimbles I've made. It is a very good insulation and unlike fiberglass it allows water to pass through. Wrapping the the exhaust or intumescent paint will allow the wood to be the closest. Asbestos is not longer used......look for "glass felt insulation". If you use inumescent paint use a dark color (black) as it attracts dirt and is very hard to clean 2011 Cameo 34SB3 Link to comment Share on other sites More sharing options...
Brad NSW Posted February 15, 2018 Author Report Share Posted February 15, 2018 The paint looks like a perfect solution! Thanks Alloy. Anything close enough to make me nervous will get a coating of that. 2010 Freightliner, DD15 Eaton Ultrashift, 2015 New Horizons 5th Wheel.
