I will be installing a 1402 Napolean insert into my existing fireplace. What is the best length to cut the wood for this stove ? Any input about this insert is appreciated. My house is approximately 1700 sq feet. Thanks
 
I would cut everything at 15in. Then you can load straight in and have some extra room in front and behind the load. The stove likes dry wood...good luck!

15-16 is good for that box. IIRC it's 18X18 roughly so you can go EW or NS easily at that length.

Napoleon says that 16" is the ideal length for this stove.

Thanks very much Mike. This is the first time I have participated in a thread such as this. I am having a bit of a struggle navigating around. I will certainly heed your advice. I assume you are happy with the 1402 ?
 
Yes, Adkheat I was very happy with the 1402 (recently sold the house). It heated my basement awesome. This was my first stove, picked it up used on CL and installed it myself with a full length liner. I have to admit, this site was key for help and questions. Some parts like the trim where missing so I made my own. The stove takes a bit to get up to temp but after you get it cruising its awesome, heats like crazy. All the brick around my set up really held the heat. You will be happy with ours. Here is a picture of my fireplace as I was remodeling my basement. I used to like to sharpen a chain or two while adjusting the stove with the next full load.

Hey Mike M., Nice setup ! My house is a frame 100 year old farmhouse, not very big approx. 1700 sq feet. The fireplace is in the middle of the downstairs, which is fairly open. The stairway to upstairs is an open staircase with three bedrooms upstairs along a straight hallway. What are the odds of this insert supplying the majority of my heat needs ? I have a good efficient oil furnace ( Buderus ) and the house is fairly well insulated. On a normal winter I use approximately 4.5 gal of oil a day. ( apprx. 600 - 750 gal. per year ) Hoping to show the relative efficiency of the house, although we don't keep the thermostat real high either. ( 68 ) I would really like to reduce the amount of oil that I am using.... Thanks again
 
By chance is the Buderus a boiler?
 
Not sure what you mean. It is an oil fired furnace supplying hot water baseboard system. There is also a hot water tank coupled next to it that supplies all of my needs. I do not have a separate hot water heater. By the way when I access this thread from my e-mail I get right in. When I try to get on from the hearth.com web site it says that my user name is wrong. Any ideas ??
 
That would be a Buderus boiler system. A furnace is hot air.

Not sure about the login issue. Did you change password at some time? Start a conversation with webfish to have this checked out.
 
That's a tough call. It depends on a lot of variables from the wood dryness, home insulation, stove location, outside temperature and the operator. The 1402 is a decent heater and it certainly will help a lot with reducing the heating bill. It may need some supplementing on very cold days and nights, but that is ok.
 
To maximize the heat output of the insert consider adding a block-off plate under the damper.
 
I would use extreme caution when burning wood with that boiler system. Problem is when the insert is cranking the boiler will not cycle and typically the water pipes to baseboard run on outside walls. I had this same issue and decided to fill my boiler with anti-freeze. Another solution is to turn on the boiler every few hours in cold weather to keep the pipes warm. One other solution is to wire the boiler pump or pumps hot all the time to keep the water moving. Just an FYI and yes the insert will likely heat your house in mild to cold weather. Depending on your loading schedule it may heat the place with little help from the furnace.

Yes, I had planned on filling the system with the antifreeze. Most folks up here in the Adirondacks do it anyway in case of power outages etc. Also I will still be making domestic hot water with the furnace, so it will be running fairly often for that as well as backup to the stove. You have been a great help.. Thanks
 
When installing an insert like the 1402 I have heard several opinions on the importance of insulating the stainless chimney liner. I will be putting a flexible 6 in. stainless liner in an approximately 35 ft brick chimney that is structurally sound. The chimney is located in the center of the home, not on an outside wall. I had planned on wrapping the liner with one of the blanket type kits. Is this recommended ? Thanks
 
That's the safest way to do the installation. Be sure the chimney is fully cleaned before installing. Pay attention to the smoke shelf area. A lot of old sweepings can accumulate there over the years.

35 ft is a tall chimney. Is this a basement installation?

No, It is a fireplace in the living room area, but it is an old Adirondack farmhouse with a high pitched slate roof and the chimney extends 4 feet or so above the peak of the roof. Thanks for the liner advice.
 
One thing I did is make a few L-shaped brackets to secure the liner to the stove. The top of 1402 is just an air channel so I drilled and tapped it to secure the L brackets. Another thing I did was make a stainless steel chimney cover to fully cover the square clay tile flue and secure the round liner at the top. It was amazing how rigid the liner became after the installation. The only real trouble I had was cutting out the old smoke shelf and metal fire back in the old fireplace. Actually wore out the gears in my favorite Milwaukee grinder during the process. A small price to pay, after all the fuel oil savings!
