New Endurance 50f

Hey Old Fart,

All these units seem to burn a bit dirty. The real indicator is what colour the inside of the fire box turns. You should see a light brown ash. If you look up my thread on my install you'll see some pics from Dex showing the inside of his fire box. It's super clean burning and is actually more of a grey colour. Here's the link:

Go to page 25.

One thing I see with your build up on the glass is that it is very uniform. Mine only builds up on the one side of the glass as the flame leans way to the one side.

Also, as The Guys are saying, you've got some tune in time ahead of you.

 

Not sure if I know what you mean Dex. But sometimes the old brain gets a little slow.

 

My furnace guy is coming over this morning so we will see if there is a problem with the return air.
Thanks all for the answers.

What Dex is saying, you're not connected to the propane furnace which is connected to the duct works of the house so how are you connected? In your pictures you're connected to something.

 

Propane furnace is no longer connected. I moved the duct over to the pellet furnace.

 

How many registers in the house? Hot air that is.

 

Right now 7. I am going to add 1 or 2 more for the basement. Right now there is only 1 down there.

 

I remember you mentioning only 7 but I wanted to make sure. The less the better because of the limited cfm's of the distribution fan. Mine doesn't have a punch of air either but by being more continuous makes up for it!

 

My furnace guy was in to check but didn't have his gauge with to check the pressure. But he did tell me that the 10 inch flex pipe
I am using will only produce 300 cfm and a 10 inch smooth wall pipe will only produce 325 cfm. He checked his chart and I would have to go with a 14 inch round pipe to get close to the 800 cfm the blower produces. I will try it this way for now and just add a couple more takeoffs for the basement to get more heat down. He tells me that my furnace seems to produce a lot more heat than
his St. Croix does. Guess we have to wait for colder temps to really try this puppy out. So far though I am happy with it.

Not sure that sounds correct, if your not getting the blast of air now .....a bigger vent will make it worse. You need the right size which is 10" but smooth walled will flow better with less restriction.

 

I don't know much about it at all. He looked it up on his formula chart and that is what the numbers were.
10 inch flex was 300 cfm. 10 inch smooth wall 325 cfm. 14 inch was something like 750 cfm.
I will just keep playing with. Keep the thoughts and advise coming. I feel a cool one coming on.

I thought the same , but I think he is saying he disconnected at the main furnace. Then installed the 50f from that point so it uses the existing duct work. He has the term "free standing" wrong...well technically....because he didn't run a seperate set of ducts throughout the house. He is still using existing although the main furnace isn't hooked up. At least that's what I got so far, I might be wrong. As far as I know with all the research I did before doing my install, the duct is sized off the furnace BTU output, not the CFM. I knew and understood before firing up , the 800cfm blower would NOT be like my 2000cfm blower for the oil eater. Which shot so much hot air so fast it gave my wife bloody noses from the amount of heat rushed up. But also cooled down the house so quick. Now I have less blowing up, but HEAT SOAK baby! Even the floors are warm.
I'll never go back, unless of course it's an emergency.

 

Totally separate from the LP furnace. Pellet furnace is standalone hooked to its own duct and return air. I am going to try to attach a chart I found online for duct sizing and air flow. If it doesn't work you can check it out yourself , just type in home duck work sizing and air flow chart you should be able to find it. Have a good Xmas and tell the young lad of yours congrats on that first buck. It is a beauty.

Kinda screwed that other reply up. Hear is the chart. Sorry Dex I cant make it happen

 

Nope, not yet......

 

Oh ok, in that pic it looks like a plenum.
