Hello all,
     Over the past several years I've spent a quite a lot of time on this site.  Many of you have probably seen some of my posts and pics.  It's been quite a learning experience over the years.  I've spent way too much time scratching my head and getting frustrated.    I have recently replaced the primary air channel in my E2300 again.  I refined and simplified the design quite a lot and so far it seems to be working well.  One necessary additional accessory is to add the spacer bar kit on the sidewalls.  Or, make your own.  I think a U-shaped piece of rebar would work well leaning against the walls and is much cheaper without having to weld tabs onto the sidewalls.  Also easily replaceable and removable for cleaning.  The main reason for adding this is to help keep wood from sitting on the pipes.   I'm attaching a full parts list to fit my furnace.  Note that I have had my sidewalls relined with 1/4" plate so my firebox is slightly narrower.  Not enough to make a difference I don't think but you may need to increase the width of the channel by 1/2 or so on each side to keep the pipe as close to the sidewall as possible.  I drilled 5 holes in each side.  30" pipe.  Drilled a 1/2" whole in 2" from each end and spaced the remaining 3 holes 6 1/2" apart.     

I'm happy to try to answer any questions.  Hope this info helps somebody.

I guess I'll have to try to post the pictures tomorrow.  Keeps telling me the upload folder is full.  Hope this goes through.

Dwneast77 that sounds like a lot of work. Were you aware that CB now has a number or kits to upgrade those older E2300s? They now have removable side air channel kits and a new secondary air system in which you take out all the firebrick and grates in the firebox. E2300s seem to work much better with these changes.

boilerman,
    To start, my air channels started falling apart before they offered the removable kit.  I did contemplate getting the kit last year or the year before but in thinking about it I felt that it would be more of a process to clean the firebox.  Getting those pieces out would require a complete shutdown and cleanout of coals and creosote.  My pipe system is removable even when there is a bed of coals.   Also, last year I had to have the sidewalls relined with 1/4" plate.  I had the welder take the new sidewalls right down to the bottom,  over where the old channels were giving me a nice straight sidewall.  Remember I had the oldest version of the 2300 which originally had a lip on top of the air channel where a double stack of firebrick sat.  All of the secondary air pieces have been upgraded.  I have the new fusion combustor and got rid of the grate bars and floor refractory which were a pain. 

5050racing,
    I tried posting my pics last night but it kept saying upload folder full, even with just one small picture.  Tried several times.  I'll try again now. 



The hardest part of the job is getting the old channel out.  Piecing the pipes together is easy.  Just take the time to get them as tight as possible.  The channel basically supports itself when in place.  If necessary one could prop up the front ends with a piece of steel or brick if necessary.  Drilling the holes takes an hour or so, or at least it did for me.  I expect I'll get 2 seasons out of it.  Then I'll make another.  Cost is around $90 for pipe fittings.

I just tried posting this with pics and was denied again.  sorry.  I'd be happy to e-mail them.  PM me.

I have a 1450 but would like to see it,me looking a maybe a new blower motor 1 season,spins free,oiled????Power to and past plug?

     Do you question whether your blower is working?  I'm not familiar with the 1450 but should be similar to 2300.  During run cycle open up the back door to access the air box.  You should see and hear the blower fan running.  If it is, then I'd open the air box and make sure both solenoids (primary and secondary) are open.  If they are, the next step would be to maybe remove the top (primary air) solenoid to check the air tube for creosote build-up.  Clean out if necessary.  If I'm not mistaken, the 1450 air channel in the firebox is welded in place (same as the 2300) with no way to clean it out thoroughly.  To check that you would need to let the fire burn out and probe the holes with a rigid wire or something.  If the primary air tube is backed up to the solenoid with creosote, then it stands to reason that the air channel in the firebox is plugged up.  It this appears to be your problem I'd be happy to send the pics of what I've done.  Just pm me your e-mail address.
     If the blower is not working, one more quick test would be to temporarily wire a plug end onto the blower wires and plug it in.  If that works there might be another electrical issue.

Trying one more time to post pics.  Let's see if this works.

Cool!  Here's a couple more.

Slightly off subject,  but does anyone have any pictures they could share showing the inside of the E2400?  I'm particularly interested in the primary air channel setup and wonder if it would be worth trying to retrofit a similar design into my E2300.  I think I saw one out here once a couple of years ago.  If I remember correctly it was quite damaged.  I wonder what they have done in newer designs......  I have not had the privilege to get out and see any new models.
