25-PDVC First Test Burn - Leaping Sparks Issue

[tyru007]

Installed a Englander 25-PDVC in a corner position with a 45 degree and 3 feet of horzontal pipe straight out to a horz cap. Air intake is about 2-3 feet of flex 2" pipe to outside. I did a test burn this morning. Burn went very well but I noticed a very active flame with a lot of sparks leaping from the burn pot. Even had a few sparks existing the vent cap at the start of the burn. No black smoke at all and a very clean burn with a 4-5" active yellow flame with a little blue at the bottom. Are the leaping sparks normal or a sign of too much combustion air for this stove?


I bought the stove (almost new) from a friend which came with the typical duravent kit. I tried to install the vent piping system per instructions to come out the side of the house and then up 5 feet with a 90 and vent cap but could not get the Tee to line straight up when everything was twistlocked into position. What I currently have is stove -> pipe adapter ->45 Elbow (with swivel on stove side) -> 1' straight pipe through wall thimble -> 2' straight pipe -> horzontal cap.

I have a cleanout Tee (with no swivel) that will not line up properly when locked into the pipe (off at about 30 degrees from vertical). Am I missing something?

As for your "sparks" during burning, there is always going to be some of that.....the fact that the air is being brought up from underneath makes this happen.

The way my stove manual describes how to set the combustion air control, basically you set it so you have an "active" flame, but not so high that the air blows the pellets out of the burn pot. I guess you turn air up until you see pellets about to get blown out (jumping around), then back it down a little.

As for the sparks out the vent, I have seen this on a friends stove.

Read up on the control board for the correct settings someone may have changed the factory settings.
There is an thread some were on here about Englander factory settings and if you call the company with your model and serial # they can help you to set it correctly. Do a search "Englander factory settings" on this site.
I ran mine for the first time Sunday and had a few sparks flying about here and there but no big deal.

tyru007 get an adjustable simpson pipe part # 3012A and it will solve your 30 degree line up problem it only locks on one end.

Try this configuration- Stove, stove abapter,adjustable pipe, 45 elbow, 1 ft pc through thimble, TEE , run up to 90 elbow , 1 ft pc, then cap.

Seal all joints with high temp silicon too.

The vent ppe doesn't have to lock totally as long as you high temp silicone between the innner and outer pipe to make the pipe a soild joint. Make sure the joint is engaged and started to turn to make sure it is safe. Once the silicone cures the pipe will not come apart so make sure you get it right the first time. I always silicone all the joints from the back of the stove to the first joint outside the home.

Slink I did the same thing high temp silicone between the inner and outer pipe to make the pipe a solid joint.

I found also that I needed to check the high temp rope or what ever in the fittings sometimes they appear to be just jammed in and don't make a perfect seal could that cause a problem especially closer to the unit?

 

[slink]

As long as you get it to turn it should be seated. I run a bead of silicone all around where the gasket is to make sure its sealed. The rope gasket is the same stuff as around the door so it can leak if not completely seated into the male/female joints. the silicone assures a soild seal. Never have to worry about any smoke leaks, remember the vent pipe is positive pressure and any leaks will allow exhaust into the home. Thats why we always silicone all the way to the outside and never leave a joint inside a wall, soild pipes only and never a telescoping adjustable pipe in the wall.

The sparks are the fines burning......
some sparks are normal
alot of sparks mean your pellets have excess sawdust(fines) in the mix.
which means they have been handled to much or they are a poor quality pellet..

Hi I also have an Eng lander pellet stove. I had to shut it down as my neighbour seen tiny sparks outside and call fire dept on us. They came red lights flashing of course thinking I had a fire. The tiny sparks dissolve before they hit the ground. Any one else with this problem. I got the stove at Home depot and the pellets they have also. It's freezing in here I need to know if it is safe to run or did I make a bad decision buying it? It has a 45 degree angel and vented through the wall . Stove in Cornor position. Thanks. Barbara

That's actually normal for the typical exhaust kit you buy from HD or Lowe's. It's short run does allow some hot ashes to exit the pipes.You can extend your exhaust run higher so the ashes go out before it exits the pipe. Another 3' should do it.

 

[bluenoser100]

that would be hard to do as the vent hole is huge. If I ran it 3 ft higher outside that would wreck the silicone seal already in place, look terrible and cost about another hundred dollars I don't have. Would a piece of fine screen/mesh work over the vent opening? Barbara

If your exhaust exits the recommenced distance from the ground and from combustibles like grass and shrubs the sparks really shouldn't be a problem. The sparks going out before they hit the ground is what's suppose to happen. However, you might want to explain that to the neighbor before you fire it back up. ;-)

I agree with GVA on this one. The quality of the pellets I'm burning has an awful lot to do with how many sparks I see in the stove but I guess the blower setting could have an impact on this as well.
