MK VII manual upload link.

Sorry guys the admin here is deleting my posts (without explanation) with the links to the Longwood manuals that everyone is asking for. So, just email or pm me for it. [email protected]

Spoonhonda - I just tried the "MEGALOAD" link, and I was able to download the manual. Thanks. Seems to be an awful lot of opinions of how much wood I can expect to go through. There are just too many variables involved for anyone to make an absolute statement. Everyone's situation is different. Has anyone tried to heat water with this unit?

longwood manual?

:help:
I was wondering if you ever found a manual, and if so could I pay you for a copy?
any help would be appreciated. Thank you.

Does anyone have any experience with setting one of these up. Have a manual or anything. I just picked one up and it is like new. Maybe used a season or had a couple fires built in it. Maybe none. I don't know.

UPDATE: I did a search and found someone on Bobvilla that had the manual. She had taken copies and sent me a PDF file on the entire manual for my exact furnace.

I have been reading the manual and it is quite interesting. In order for the furnace to work correctly it requires 4-5 foot long pieces of wood. It said you can use slab wood but it needs to be mixed with some pole wood! But hardwoods are the best for burning as it "charcoals" up better. But anyways. It is a dualfuel furnace. Which I just thought that the propain-ng, or fuel oil burner was only used to light the wood or to heat the house when the wood supply was gone as a back-up. WRONG. This furnace is a 0 natural draft furnace. The dampner door is closed at all times, except when loading wood. Or burning only wood when the electricity goes out. The furnace is to use the propane burner to light the wood and keep it "charcoaled" up when you need heat. The coals stay hot and the flue piping stays a constant warm temp. The propane burner is to only run around 5min. to get the coals going and then it shuts off. There is a heat reclaimer just above the main firing chamber to reclaim some heat, but they said it shouldn't be run all the time. Only if it is overloaded and it is too hot.

I didn't know that the propain HAD to be used on these units in order to work correctly! Now I'm kinda bummed because I want to use 0 propain during the winter months. I guess I'll get it hooked up and see how much propane it does use. It says that it is extremely effecient with the gas and that most of the heat is from the wood. But I'm guessing these units were made in the 80's? I looked at the serial number to see if something resembled a yr. made. The last 2 digits are 71. So that could be the yr. it was made I have no idea. All I know is it is heavy. Crate weight is 550lbs.

We have actualy had our furnace since my husband bought the house in 1989, I had even contacted the longwood company when they were still in business and ordered a manual, it sat around for years and we never needed it.
Now that there is a need for it, my husband is unable to figure out what he did with it.
You have no idea how greatful I am that you have one.
Did you want me to pay you for a copy of it? I would be more than happy to do so.

Longwood Help

I have been installing a Longwood furnace in our shop and have gotten along real good except one problem. I can't get the auto air damper to work.It had an Adams Speedflame burner on it that I removed.Now I can't figure out how to wire the thermostat to make it work.I have 24 Volts at the relay and can get the relay to work but the damper won't open.There are two wires that came from the Adams unit that I figured was to cut off the damper when the burner fired up.So I need to know how to bypass the gas burner and just wire the thermostat to make the damper work.
Thank you for any help you can give.

P.S this is a great site!

Longwood Mark VII help

The size of the manual to the Longwood Mark VII, which hopefully provides you the help you need, is too large for this site. If you send me your email address, I can get it to you that way. It is just over 4mb in a zipped file.

Hi all. I am a bit late to this thread, but I have had a Longwood for the last 26 years. First of all a big thanks to spoonhonda for the PDF of the instructions, don't really need them at this juncture, but ya never know.

For the first few years I didn't use the gas assist, and got along OK, but a friend came by and we figured it out. If you can use the gas or oil I highly recommend it. Fires are SO much easier to start and maintain with the gas. It makes no sense to not utilize the full capability of the furnace if you can. I have never put any wood in that was over 36 inches long and have had good results with the furnace. About 15 years ago it struck me that the reason that I burned quite a bit of wood was that there wasn't much heat sink, or thermal mass in this furnace, so I loaded the rear 2.5 feet of the fire chamber with glacial erratic, or field stone. This greatly enhanced heat retention and therefore reduced the amount of wood needed. As was stated before it is hard to figure out how much wood you need as winters vary greatly. Case in point, we had a high of 53 degrees on Tuesday, and it's near zero today, Thursday. When I purchased this house it had little insulation in the ceiling and zero in the walls. The ceiling had been lowered and there was R10 insulation. This last summer I took out the lowered ceiling and took the height back to the original 10.3 foot cathedral and sprayed foam to 5 inches and then covered that with an additional 2 inches of solid foam board and then 7/8 inch OSB and will cover that with drywall. The walls are 2 feet thick concrete with a stone exterior, and have no insulation which gives an R factor of zip, less than 1. The walls are as we speak being stripped with 1X2 and insulated between with 3/4 inch solid foam and then covered with another 1 inch of foam and then by OSB and then drywall. With just the ceiling finished it is much less drafty and cool in here. The envelope is about 1900 sq. ft. and all the walls and floors inside and out with few exceptions are concrete so it takes a bit to warm them up, but they hold heat like a demon holds a sinner.

The Longwood had been a great furnace, and has been zero problems so far. My only complaint is the pilot light goes out on VERY wind days and is a pain in the azz to light. JR
