whitfield profile 20 start up smoke

[coachmen98]

I have a profile 20 pellet stove and just moved it from my living room to the basement

I just cleaned the stove including the plenim and all of the pipe and exhaust ports

Chimney
The stove has a clean out T, 4 feet of verticle pipe, to a 90 degree elbow to outside and the chimney pipe is clean.

On start up teh chamber fills with smoke and smoke comes out in the room.

Lennox says change the combustion fan motor
a dealer told me tha this is a problem with these stoves

I inherited the stove with the house and it seems to be in very good shape.

Any suggestions would be helpful

thanks

Jim

Need more info on your pipe

you say
The stove has a clean out T, 4 feet of verticle pipe, to a 90 degree elbow
then what? what kind of pipe after that?


Start up smoke i kind of normal but not a lot of smoke.

All the pipe is 4 inch ID

2 foot horizontal pipe to and excuse my desription to the stainless steel dryer vent "

With that type of install you will get start up smoke. and smoke when the power in interrupted

I would go up with pipe on the outside
but if you dont
I would put in out side air.

Be sure to have ¼ inch per foot of rise in the horizontal run.

the hole through the concrete wall is angled But this is only a start up problem and I had to take the stove off of the thermostat
when it starts to me the combustion blower is not strong enough to pump the smoke out but once lit it works fine
I am absolutely stumped

a blower motor and a super igniter are almost 300 bucks just to try it and they may not help

FYI the SUPER ingitor is nothing special
We do not sell them only Lennox direct parts.

On start up the Air in the pipe is COLD and heavy
this is why you need to be sure you have good rise in the pipe and proper draft.

I was thinking I needed to add a fan on the exhaust pipe but they dont have them in 4 inch, Does anyone think that my combustion blower is the culprit not being strong enough at start up??

Thanks

I was also getting smoke in the room at startup. I replaced my gasket and that solved it.

 

[coachmen98]

Its comming out of the windo wash slits in the glass

 

[smg64ct]

My smoke was coming out just at the top of the door.

The inside of a pellet stove is a vacuum
the only way smoke will come out of the front of a stove is
if the Venting is Not enough draw
Blocked ash trap Exhast chambers
Blocked venting
not enough rise in the venting
Bad blower

what kinda shape is the door gasket in , and the window gasket. does the unit have a "missing gasket type" airwash? i agree with rod, usually an igniter stove will produce a faint whiff of smoke just as the unit ignites to a flame , then its gone , usually thats from the small clearance around the shaft opening for the exhaust blower fan but above the door means that you are not moving air swiftly enough , i'd think an ash blockage either in the exhaust path between the fire pot and the exhaust blower, or a blockage / restriction in the pipe. or possibly negative pressure in the house. to determine neg. pressure , open a door or window to outside about 5 minutes before lighting the unit, this allows time for inside pressure to equalize with outside pressure, then if the unit starts clean and doesnt smoke , add an "oak" if not , find the blockage and remove it

OAK??

Oitside air Kit I am new to pellett stoves but that makes sense the profile 20 outside air hook up has no baffling to the burn area

it just hooks up to te rear cover

I adjusted the door
that eliminated 90 percent of the smoke in the room and
I tried a used combustion blower another friend of mine had
3 days burnin no clinklers and no smoke. now how to buy a fasco r7-rbm120
without all the extra parts on it. Is it me or is it teh niche of being put on a pellet stove
that instantly makes the parts more expensive.

Our prices are high because they are the complete blowers and housing
with Fan blades and most of the time gaskets and wire connections with Molex connections adapters come with the kit that are Original Manufacture part OEM.

You can use after market parts and Build a blower but you dont get gaskets
some times you dont get a fan blade, and if you do they are not the correct pitch for the right air flow or volosity.
and some times they are not tested for the Heat rating needed

You can save money by building your own but 90% of the people dont have the tools, Time or knowledge to take apart a blower and rebuild.

Some of the older blowers that came on some stoves did not have the removable mount on the housing
they were one piece.

Old style blower without the flange on the housing to remove the motor and fan blade only.
