Barometric Damper on Newport Diesel Heater

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.

Re: Barometric Damper on Newport Diesel Heater

Did you ever complete the installation of the Dickinson Newport on your Westsail? If you did, how has the stove been working without the damper or any issues you'd caution against? I'm dealing with similar circumstances/questions for my own installation. Thanks!

Re: Barometric Damper on Newport Diesel Heater

I recently installed a Newport and have fired it up a few times for a few hours each time. I have no damper and just under 5í of pipe with a slight jog. It seems to work well but does take some playing around with the fuel and fan to get a good balance at first. Gusty winds the one time while I was burning and I kept the fan on to keep the flame from pulsing.

Re: Barometric Damper on Newport Diesel Heater

I had a Newport Dickenson heater in my old boat, originally without the damper, but later added it. It greatly improved the stability of operation on windy days.

If it is giving someone lots of problems, it is the installation, (or the operation) not the heater itself. They are very simple machines.

Re: Barometric Damper on Newport Diesel Heater

I have a Newport bulkhead diesel heater with the damper installed. You do have to play around with the fuel amd fan settings in windy conditions. When the wind exceeds 20 knots, proper use of the damper greatly reduces fiddling and nasty backdraft. The backdrafts really do suck.

Re: Barometric Damper on Newport Diesel Heater

Hi. Had a Newport running nonstop for weeks at a time while building a boat in RI.
H cap. Stainless thick wall. Stainless thin. Copper pipe. Long run and short.
Made a barometric damper which improved everything no matter what pipe length. Would leave the boat with the heater running as I constructed a seperate fuel shut off if the cabin got too hot. I did not trust the provided valve feature.
Used a solid bronze water deck fitting. 1/4 “ cement like heat board and stainless shielding. Tossed the original fan underneath. Heater valve is numbered and must match the diesel. Preheated the stove and pipe with propane torch. Roll a paper joint in diesel to light. Put a tee and plug in the bottom to ease cleaning. Ran it for hundreds of hours. Spoon for cleaning the carbon out then poke out the tee. Often ran with a little lift under the valve screw...about the thickness of a match book cover. Gravity tank, small filter and good size fuel line. Some deck soot but it ran in winter snow storms and gales. Toasty in 31’ insulated glass custom build. Liked the copper pipe above deck but thought about double wall. Almost built a Concordia head in copper but the H head worked fine.
Current boat Webasto air and two Esper hydronics.
Regards, Mark

Re: Barometric Damper on Newport Diesel Heater

Hi. Woke up. Webasto fan / burner surged. Just old ...Died after many good years of flawless running. Needs complete overhaul.
Hydronic system under construction. Have hot water but no matrix boxes yet.
I removed our trusty Newport and put parts ashore. 6 hours later, after two years without running, I reinstalled the Newport, the chimney and the H cap.
Fixed up a temporary fuel tank and sort of cleaned the heater interior parts.
Fired it up after two years. Took a while to remember all the places to clean the fuel flow. Now, on a gravity 5 gallon jug, itís running perfect. Nice blue flames above the ring. Pilot house getting warm and dry. I will never remove it again.
One needs to re engineer several things to max this heater but itís so simple.
Iím amazed how easy it was to completely re install it.
No electricity. Simple. It does not heat a 60í boat but we are toasty tonight with some heat. Please consider the cumulative experience of those who post.
Show me the boats you have built with your own two hands...how long at sea...where? Itís not perfect for all boats, but Iím a warm and happy manatee. Mark the manatee.
