baby its cold inside..HELP

PostBy: boxerbabee71 On: Fri Nov 29, 2013 3:48 pm

Hi all. Was hoping someone could help me out. Its my 5th year with my keystoker. Its a direct vent. Upgraded blower (90). Last year at the end of the season I noticed the heater wasn't keeping up with the cold. I turned up the feed...gave it a good cleaning but the temperature was dropping a couple of degrees a day. I used to get it to 80ish in the room with the thermostat but I can't get the heat to 65. I can't figure it out. the direct vent pipe outside is the onlything I've changed. I have the blower in a T with two ducts coming off. One in my living room where the thermostat is and the other in the bathroom. I mean I have changed nothing. I opened the vent a wee bit. I opened the feed all the way up (which I've never had to do) and I'm burning coal...same coal as always... but getting no heat. So what can it be...gosh I hate being cold and I hate it even more when I have to buy oil. My house isn't all that big. the furnace used to make it that I had to open windows.  the stoves in my basement...2 vents off of it. Which the space on my main floor is a box shape and maybe 500 sq ft. And I'm probably exaggerating that. Hope someone could gimme some idea to help me get it back in the 80s again. Shoot...I'll take mid 70s at this point. Anything will help a$ long a$ I don't gave to heat with $oil$...ugh what a s carry thought.
Thanks

In your cleaning process what was done? Pictures of burn on grates will also help. Shooting in the dark here so more info will help. Is grate full, any foreign objects blocking coal in hopper/ stoker plate? Change coal supplier? Clean fines from under grates?

Welcome to the forum. If it worked before and doesn't work now it means that something has changed. Do you control the feed and air by hand or do you use a Coaltrol? Is the height of the fire different? You said your using the same coal, is it from the same supplier, same size etc.? Did anybody "fix" the stove for you or try to fix it for you?

If you fill out your avatar with your general location there might be a forum member near you that could lend a hand. Also take photo's of the unit and post them. I will also ask what is probably a silly question but by chance is the manual pipe damper in the flue pipe all the way open? I had that happen to me one time with a hand fed stove. Let us know and we'll see what we can do.

Hi wiz..thanks for the reply so quickly. I clean everything... from taking the grates out making sure all holes are clean. Of course I clean and oil the fans and motors. the furnace is set to blow at 220 or 240, either way its kicking on and blowing every fewminutes. the coal feed is working fine out of the hopper. the grate is full especially since I turned up the feed. I'm using the same coal man as I always used which is the same coal the keystoker distributed recommended. I think there's a difference in the size of my flame though. Its not as high and bright as it used to be. I never checked the draft. Only because its preset. I don't know what I'm doing wrong. I'll attach pictures of my flame...as for the glass I could never get it very clean thoroughly...so its yucky. Thanks again.

Don't own a stoker but have read a lot about them and it sounds like your combustion fan is slowing down or you have a blockage of some sort, you said the flame isn't as high as it used to be. No matter what stove you have (hand fired or stoker) air from under the coal makes it burn and with more air you get larger flame and more heat, this is the area I would look into first, then I would look at the draft by using a manometer to see how your direct vent is set.

When you put the grates back in you did seal them with refractory cement right? Sealed at the top, down the sides and down the middle? If not you could be getting air bypassing the lower part of the grate. Is the fire line straight across or does it look kinda like a mouth shaped like a frown or like a smile? :) :(

Also double check that the opening to the combustion fan is open all the way and not obstructed.

similar issues recently posted turned out to be a restrictor plate on the combustion fan being closed more than prior to the cleaning. i cant remember if it was your model stoker.

as mentioned a lower flame means less air getting through the bed of coal.

even though you have the same supplier is this years coal about the same size a previous? if you got a scoop near the bottom of the pile it may have a lot of fines.

is your coal wet that is being fed from the hopper? that is something that had a big effect on my stokers performance. dry coal nice fire and a lot of heat. wet coal and poor fire and much lower heat.

Have you taken a small brush and cleaned the squirrel cage combustion air fan to remove all the dust and dirt that gathers there? When those curved surfaces get loaded with fuzz etc, the air flow drops dramatically. Any flame pictures yet? Mike

Can hear the thermostat clicking on/off on the stove when calling for heat?

What's your FEED RATE Screw set to? How many turns out?

When call for heat, and at full burn do you have about 1" or a little less at the end of grate?

Whats your inlet combustor restrictor plate set at? about 1/2 closed?

If you don't have a draft gauge, get one. You need to set the Direct Vent up properly, otherwise you could be sucking more heat from the stove out the chimney.
