Problem With Keystoker 160 Blower Help !!

Hi

I have a Key Stoker 160 Furnace with a 1500 CFM Blower motor on it first year of use and have been using for 2 months into the heating season with no problems and just love it. The Furnace is connected into my duct work for both hot and cold air supply. When I went down to check it today before leaving for work the blower motor that blows air into my duct work did not seem to be operating at full speed this AM upon furhter checking when I came home tonight it's taking longer to heat the house up to desired tempature of course it's much colder tonight. I'm trying to figure out of I have a problem I;m not sure but it just seems like the blower is much quitter. The Key Stoker manual says to ceck the blower motor and clean if it appears to be operating at a reduced speed.

I just retruned home and are wating for the furnance to cool down some so I can tear into the duct work to check the blower motor to see if it's dirty from only 2 months running but I don't have a good feeling this is the problem as I keep this thing pretty well clean by vacuming around the furnace weekly and even vacuming under the ash pan once a week.

Anyone have a similar problem or ideals on what to check ??. Joe in SYracuse NY.

UPDATE: I removed the duct work on the blower last night and checked the blower thourghly and it's clean, but the stove seems to be taking loger to warm up the house the blower is running but does sound some what more quiter it takes approx. 2 hours to raise the tempature of the house 2 degrees, it would normally take approx. 1 hour. Any one have any ideals ?.

You don;t have any rehostat or anything on the blower? It probably only has a temp. switch for on/off?

Does it still seem to be blowing enough air? or reduced? That's seems an awful long time to heat up....

Do you have a temp. monitor your exhaust or stove temps? Maybe you have to adjust the feed rate, your baro may not be working correctly or stuck and, more heat going up the chimney,??

Check other things...
Is it feeding correctly? Maybe a clinker not letting the stove heat up? maybe the combustion blower not feeding the stove enough air to burn correctly? Something could have worked loose and caused the stoker, blower, etc.l

I take it the problem seems to be air circulation more than lack of heat are there any filters in the system, coal can be a bit more dusty and 2 months sounds about right or even a little overdue for filter cleaning or replacement in a dustier environment

How do you check the baro your correct there is ony a tempature on off switch I also checked the filters in the filter box on the cold air returns and the filters are clean on Saturday tommorrow I was going to take the direct vent motor apart along wit the direct vent pipe that goes out doors all apart and clean everything from the direct vent fan through to the exhaust out doors to see if that makes a difference. I have been running approx. 2 months and have not cleaned this out, so I'm guessing it's time and hope this makes a difference my wife and I were talking tonight at dinner and we both seem to agree that the furnace appears to be taking much longer to heat the house up. So I very much appreciate the help and suggestions on what to be checking.. Again in checking the cold air supply from the blower through to the filters all looks clean so far.. On Saturday I will do surgey.. Thanks for the help this is a great Web site, the coal man that manages this site is a hero.. It seems to be blowing reduce air so I;m not sure how cleaning the direct vent pipe will make a difference on the blower motor but I just may be losing my mind and the bloer motor is working corrcetly.. Thanks Joe
