Re: Hi Seas Heating Corporation / Diesel Heater

Will, welcome to sailnet! I may be able to help you when you are able to take and post photos. I use photobucket to post pics here. it's easier then posting from you computer. There are only a few ways for diesel heaters to be built. so we should be able to help you cobble up something to get you warm
this discussion may help out, assuming you need help that is.

Charlie, I know this thread is over three years old but I too am interested in getting a PDF copy of the Hi Seas diesel heater manual from you if possible. I am new to Sail net this month and this is my first posting. If it is available please respond and i will send my email address. Thanks

Re: Hi Seas Heating Corporation / Diesel Heater

Hello Hi Seas Heater owners-
We have two of them aboard Holy Grail, that we bought from the manufacturer before they folded. For a long time we did not use them as we were cruising in the tropics. We are now in Alaska and using them... or I should say it, as one is not working.

This reply is for two reasons, to provide help and to find spare parts,

I have the manual and will be happy to mail or email copies to anyone. The manual is full of tips but it is not complete. Specifically there is no drawing of the control valve - the guts of the unit - and no instructions for disassembly and cleaning.

Most units are installed with a demand fuel delivery pump, which is always separate from the heater. If your pump does not run all the time or ticks at intervals, you have a demand type pump. It pumps until a certain (low) pressure is reached, usually 3 5o 5 psi. These are the best pumps to use. When the heater uses fuel the pressure in the fuel line drops and the pumps ticks until the set pressure is reached. The heater may be run with no pump if a gravity tank is used.

If the heater does not work, in other words, no fuel is reaching the combustion chamber, and if it has not been used much, the usual cause is that the filter at the underside of the valve block is dirty. It is a sintered bronze cup which can be removed and cleaned with alcohol or acetone. The tricky part of reassembly is placing the ''O'' ring exactly right up into the unit. If cleaning the filter does not restore fuel flow, then the valve is likely plugged up. You will have to blaze your own trail with that as it's too complicated to describe and the manual is no help - just says to have ''factory authorized service.''

9/10/12 UPDATE! I just found drawings of the metering valve that I did not realize we had. If anyone is interested in a copy I can scan and email or copy and mail.

If anyone wants to discuss it further, I'm happy to try to help.

If anyone has a heater to sell, working or not, or any spare parts, I would like to buy them.

Howard, konasail

amazon43 Is there any chance of getting a PDF copy of Hi Seas diesel heater manual? I certainly would appreciate it.

deniseO30 Gentlemen.. the key component in diesel heaters like Dickinson Sigmar and others is the "oil metering valve" or carburetor, such heaters with valves like this have been around a very very long time."gravity" feed or low pressure pump just get the fuel to the metering valve.. The use of stainless steel jackets and flues make them marine type heaters. You may remember a heater that worked the same way when you went to your grandads hunting cabin!

Fuel oil needs high temps, atomization, wick, plate, pan, or basket type burner, which is heated by the flame so much it glows and acts like a catalytic converter.

So..when the needle valve is coked up.. the flow diminishes,,, the oil delivered is not enough to get the burner section hot enough to cause complete combustion.. SOOT! Learn how to clean the metering valve often.. it's the key to happy heating and sootless combustion. use of kero may help but it will still eventually coke up

here's a rendition of a new heater with the same old type of combustion your boat heaters use. Flame GLT-I

Does this look similar?

ck out this! [IMG][/IMG]

I am not a frequent user of the sailnet forum, so perhaps you could advise on the easiest means of forwarding on this document to you.

I can send by email, but that assumes that you wish to share your emial address.

Just let me know.


Charlie .. any chance I too could get a copy of that Hi-Seas heater manual from you? Just bought the used heater THEN found out how hard it is to find parts as well as the manual.
Thanks so much.

Hi-Seas, also in the Netherlands

Hello Charlie,

A reply from the other side of the big water.
I also have the type C100-8 aboard and looked up for some more information of this outstanding heater. I did some maintenance in 2009 (just cleaning) and replace the firepit(!?) with a special glassfibre. It was original asbestos.

I am very interested in a copy of that manual you mentioned!
Any chance to e-mail this manual?
I would appreciate that.

I just scanned a Dutch written manual into a pdf.
If anyone is interested (and able to read), I will send it.

With regards

brob76 Any chance I could get a copy of the manual by email? I just picked up one of these units and it would be great to know how it works before installing.

Hi-seas Heater

Thanks For The Dickenson Parts Info. I'm Interested In The "pulse" Detail Of The Pump. Is There A Chance Of Copies Of The Manual Still Being Available?
12-29-2010 03:11 PM
Aurea Thier are no new parts for High Seas but these guys have parts that will work - Propane Fireplaces

O and gravity tanks still need a pulse pump or heat will end after ten mins or so.
