    I'm getting ready to call the dealer I bought my stove from, to get annual cleaning. (I admit I was bad and didn't get it cleaned last year). It was installed in 2007 and I had it cleaned in 2008 and 2009. They charged $100 each time. I was not home when they did it.

    I found a post in this forum some time ago which I pasted to my email as reference for what SHOULD be done w/ annual maintenance. Since I was never home when they did it, I don't know what they did, but I have serious doubts they did much besides vacuum out the inside. So this year I intend to be home looking over their shoulder (they'll love that). When I call to make the appt do you think I should ask them what they do, exactly (in detail), and see if it compares to the list I got on this forum?

    The problem is, I don't remember where I found the post and which specific stove the poster was referencing so I dont' know if all things are relevant. here's a run down of what the poster said should be done for cleaning ---

    Clean exhaust vent all the way through to outside air, remove squirrel convection fan and remove lint
    Clean fine trap
    Remove sand from air intake
    Remove igniter and clean the fins
    clean the vacuum switch intake baffle
    remove the ESP probe and clean it
    remove exhaust housing plate and clean the impeller
    blow out the airwash system for the glass
    wash the glass
    remove ash from the property

    He said a good technician will also start the stove and make sure it cycles through startup, run it for 20 mins, check the magnehelic pressure w/ a gauge (you're looking for .32 inches of WC) and then monitor the shut down procedure.

    The poster said he gets around $245-270 for this. That's why I really doubt my place is doing all this stuff.

    I don't know anything about the parts and workings of the stove. I don't do any maintenance on it myself. Can anyone tell me if these maintenance/cleaning procedures are all valid for a Harman Accentra-2? Or should I just run all this stuff by the guy I'm calling and sound stupid if my stove doesn't have certain parts, etc? heh...

    Sorry this is so long!

    Thanks for the help.

    Edit--I did a search and found the original thread...

    to add to your list:
    make sure to vac out the distribution blower (on bottom of unit). Its sneaky down there, and it collects dust bunnies/animal hair like a magnet.

    Yes, all that stuff should be done on your stove too. When I called my dealer in past years to make an appointment to clean the stove, I asked them if the cleaning included taking fans out etc., I got oh yes. I didn't stand over him when he cleaned, and after he left, found out almost none of that stuff was done. Mind you, I keep my stove extremely clean, so it's not like I left a huge mess that took a lot of time to clean up. This year I had the person you talked about who posted above what should be cleaned come out to do the cleaning. He did everything he said should be done, and I couldn' be happier. It is uncomfortable to be hanging around staring at the guy who's cleaning your stove, but if it's been 3 years since a good cleaning was done, you are going to have problems if you don't make sure at least the combustion fan and distribution fan, as well as the ESP is cleaned.

    newf, I know. I took it for granted they were doing it right because I bought the stove there and they have a good reputation (or so I heard), this is Bernardston Farmer's Supply.
    I really want it cleaned right, so hopefully talking with them and being there will help.

    Hello

    I would also go to Maintenance Section page 31 of your Harmon Manual for specific items to check and clean!

    See
    http://hearthnhome.com/downloads/installManuals/Accentra_Insert.pdf

    The picture below shows the exhaust fan and the many blades it has. The blades should be cleaned very well and a putty knife is used to clean Behind the fan blades. Now I like to use spray graphite on the blades after cleaning because I found they stay cleaner longer!!! That to me is a good cleaning!!

    Also see tips on yearly cleaning of the Blowers with before and after Pics I took !!!

    Don, my stove did not come with a detailed manual like that, it only has 30 pages total and of that, only a handful are for maintenance, it's not in color, it has a yellow cover (not glossy, is cheaply made). If I was supposed to get a better manual, I never did.

    As already mentioned I don't do any maintenance on it myself, i don't have the tools or the know how, I just clean it out w/ a vacuum sometimes.

    But thanks you guys for the tips I can pass on to the dealer when they come to service it.

    Ok I called and spoke to the owner, Doug, and I read him the list of all the things that were posted here, and he was quick to say that yes each thing is done by his main stove cleanerguy, Matt.

    I'll be home when they come on 8/22 this time so I'll be watching and asking the guy as he does each thing, what he's doing (w/ my list in hand). Of course he could lie and I'd have no clue...but at least being there maybe I'll get my $150 worth (price has gone up, but is still reasonable compared to what I've seen here, IF they do what they say they do).

    Here's hopin'!

    requin- download yourself the latest manual for your unit (PDF). Should have a pretty comprehensive section on cleaning and maintainance. Browse through it a bit to get a grasp of the major component locations and use that as your guide for how well the tech is doing. Aside from accessing the dist blower, that unit is pretty "owner friendly" for cleaning. Takes some elbow grease, but no fancy tools really, just some common ones.

    what's accessing the distribution blower require?? I mentioned that and Doug made it sound like no big deal. Do they have to get under the stove or something? Can it be reached from the back?

    By the way, like I mentioned, I do have the manual that came w/ the stove, and I just did a search and found a pdf of the Accentra-2 manual, and it's just like mine..about 29-30 pages long, with info on installation, use, etc but not a lot on cleaning/service.

    This is not an insert, by the way. Freestanding.

    not really "under" the stove to clean it, but its on the bottom rear of the unit...mostly annoying to get to, making it one of those "no one will notice if I dont do a good job cleaning this" places.

    in reading all of the replice on this thread i notice no one mentioned the check the magnehelic pressure w/ a gauge. this is one of the most importan aspect of the service call. if they are not doing this then u are probly not getting the most heat for your $$$.

    I mentioned that over the phone and the owner said they check that when they install it but it isn't necessary to check it during cleanings. ??? The guy who came to clean it said the same thing (But I wasn't convinced he knew a lot, he was young and I don't think worked there very long).

    ANy thoughts on the truth of that pressure being checked only during install?

    as a stove gets older some parts start functioning slightly different, for example a blower motor might run at few r.p.m. then when brand new, the auger might turn a 1/32 or a turn less per cycle. all of this changes are minuscule, but they can affect they efficiency (and ash build up) of your stove. This is why every one of our techs checks the pressure every time. i look at it as cheap insurance that our customer will be happier with the stove
