We have a generator and aqua-hot exhaust that run side by side up through the roof. We put a gas hot water heater double wall stove pipe around the 2 to help sheild the interior from the heat. Around that pipe we put an HVAC duct because we felt it was still too hot. On top we put a water heater roof cap. We anticipate the exhaust wanting to come back down the stove pipe into the storage bay. The question is..how do we seal the exhaust out, once it has exited the bus roof into the cap, while at the same time leaving the air flow needed to keep the pipes cool? Or, is there a different solution that you might suggest? |

I would think that a prefered method might have been under the bus.Thats where my gen exhaust is. |

I do not believe you will have an exhaust problem. Hot air rises and the heat generated will cause the air entering the double wall pipe at the bottom to rise also. I also tried the exhaust from the generator through the roof but had to remove it due to the heat generated inside the coach. |

Your ingenious triple-wall solution should help from a fire-resistive standpoint. If there's still heat coming in, try exhaust wrap tape over the entire assembly. A 2" or 3" roll can be found on the ePlace for much less than retail. Then box it out with whatever finish you like. As for the cap, a bent tube like the big rigs use might help draft it better whilst underway. At any rate, leave a CO meter monitoring at all times... we ALL should. I wish my genny exhaust went thorough the roof, because we sure smell it when parked. I'll have to resort to one of those ugly contraptions that you tack on when parked. HTH, bb |

Keep in mind that if the exhaust goes thru the roof, it will spit soot on the roof and awnings that are closeby. Out the back is a reasonable alternative, keeping it away from windows. Of course this means a temporary pipe or something over the rear axle as a more permanent installation. |

If you have trouble with exhaust while traveling you mite try putting a T pipe on top pependictular to the bus, this works good on the tank vents, seems to cause a suction. larry d |
