Ok so I am getting readt to tackle the very exensive and challanging installation
of the Dickinson Newport Diesel
heater. The problem is that due to a number of factors I may have to install the unit without the company reccomended barometric damper to optimize draw and prevent backdraft. The installation
will have the "H" cap and four feet of flu. Do any of the members have experince with these heaters without the damper installed and the potential pros and cons of this type of install.
