Fehrenheit endurance

10 registers in the house. I can't get pictures right now since I am not home but I will get some tomorrow.

 

If you know what your doing and the people who install it know what they are doing. I keep thinking something cannot be hooked up correctly. How can we have no air at all coming out of most of our vents? Maybe the blower is just too small for a 2 story house...

 

We have two bedrooms up stairs with vents, the main floor has all the rest of the vents. The furnace is on one end of the basement so the 2 vents on that end of the house have air flow but all the vents that are located at the far end of the house have nothing. Unfortunately that is our living room and dining room. The bathroom and kitchen that don't need as much heat have the vents with air blowing out. I am going to quit worrying about it for tonight, it's giving me a headache. Tomorrow I will try again. I just really hope that we can figure this out, I did this to save money and instead it just cost me 6000 and a tank of propane. Didn't want to fill up again this year but with these temps and no pellet furnace we had no choice.

 

Really hope you get this figured out. IMO you are the right place to get the most informative help to make that happen.
Keeping a close watch on this thread.
Good luck !

 

That is so nice, I really appreciate all the help that you are giving me!

 

Dexter is good people...He will get you straightened out!!

 

Not sure this is even possible, but what would happen if they try to run the pellet burner and at the same time run just the fan on the propane furnace? Would that help determine if a damper is missing,or installed wrong?

What I had to do was adjust the dampers on the runs that connect to the takeoffs that feed the floor registers. My main trunk runs the whole length of the house, and there are (guessing here) 12 registers that connect to the trunk. The pellet furnace sits at the far end of the house, oil furnace is in the middle.

In my case the registers closest to the end of the house where the pellet furnace is were getting the majority of the airflow. Makes perfect sense, air takes the path of least resistance. Most of the 6" take offs had dampers installed, but some didn't. In the fall, I adjust the dampers so the registers at the end of the house closest to the pellet furnace are mostly closed, and the ones at the far end are mostly open.

Another issue I had was leaky joints in the ductwork. And I mean a lot of them. When I first connected the furnace, the curtains in the living room didn't move. That was my scientific test, as they flap all over the place with the oil furnace/AC blower going. After sealing the joints with foil tape, the curtains were moving in the 'breeze'. For me it was easy as my house is a ranch and all ductwork was easy to get at in the basement. In a two story house, I'm guessing you have ductwork in chases going upstairs and what not so accessing all the ductwork probably isn't feasible.

You'll never look like the guy in the 1980's Memorex commercials with the blower in the Fahrenheit, but you should feel something coming out of the vents. With a 800 CFM blower, a leak or open duct in a wall could wreak havoc, whereas it may not be as much of an issue with the larger blower on the propane furnace.

The above is all based on the assumption that the dampers were installed correctly as Dexter pointed out. I'd guess they were, as if they were in backwards then your propane furnace blower would be screaming like a banshee and you wouldn't get much air, if any, out of the ducts when that is running.

 

Is it live or is it Memorex?

 

That's the one.....

 

I saw that with a Harmon you could get optional larger blowers. Is this possible on the fehrenheit?

 

Sorry it took so long to reply...it was girls night out and the Bud Light was going down good!

Anyway, my Hubby called fehrenheit today and talked to them. They said that a lot of stuff is hooked up incorrectly and they will be calling the dealer to get them straightened out. They also wanted the serial number because we should not have gotten a brand new furnace with the old version of software and no upgrades. They are also giving us the control panel and other upgrades at no cost to us. (Made in America always has better customer service!)

Fehrenheit will get back to us tomorrow about what they find out with the serial number. Our dealer may not be too happy with us but we had to look out for ourselves. Thanks again for all your help guys!

 

My Hubby isn't sure who he talked to but my Husband told them that what the dealer said when he told them if it wasn't hooked up correctly it could void the warranty.

The dealer replied "they cover the warranty if we tell them to, they do what we say because we installed it"

Fehrenheit person said that they will be taking that to their supervisor.

The sticker on the back of our furnace has the serial number and it says certified 12/06. Did they even make these in 06?

 

The first versions came out in 07. They've upgraded several things since then but the safety certs stay the same.

Fahrenheit does have great support as well as a very nice facility. They're about 35 miles away from me. I got a nickel tour of their factory last year. I needed a new exhaust blower and was working 10 miles away that day so I swung through and picked up the part.

Being able to talk to the people who design and build the units can prove invaluable, especially when your dealer might not be fully trained.

Edit - I've got the old man furnace here. S/N 2349. No fancy LCD control panel here. Just LED's.
