Can the stove blower duct work be angled down to hook to more duct work?
By Collin C. - NFI Master Hearth Professional on October 23, 2013
Yes. Because of the high amount of positive vent pressure, the orientation of the vent connections can include short runs downward.

Do you have any idea why both blower motors would burn out after only about 6 months of easy use?
By Collin C. - NFI Master Hearth Professional on November 4, 2013
The primary cause for blower failure is dirt or grit pulled into the motor bearings. The circulating blowers for this unit are reliable models and this is the first report I have had for both motors failing in such a short amount of time.

How do the grates go in? Do the bricks sit on top of the grates or do the grates rest against the bricks?
By Collin C. - NFI Master Hearth Professional on February 24, 2014
When installing, the grate will rest against the bricks.

Do you make this furnace in a down draft configuration?
By Collin C. - NFI Master Hearth Professional on December 7, 2012
Unfortunately, this type of furnace is only sold in an updraft variety. It is primarily meant for use in tandem with forced air furnaces that use ceiling supplies.
By Ron from Madison, WI on February 12, 2013
I currently have a wood furnace configured for down draft to blow heated air into a crawlspace duct. Would there be any problem with placing the blowers and an air intake filter box on top or this furnace and the outlet at the bottom?
By Kevin E. - Fireplace Specialist on February 12, 2013
In researching this model furnace, there does not appear to be any provision against reverse flowing the heated air. There is no communication between the combustion chamber and the circulated air. So, doing so will not affect performance of the furnace.
The trouble will be in fabricating a plenum box to support the blowers above the furnace and a box at the rear of the unit to direct heated air to the crawl space. No factory plenum boxes currently exist to support this type of installation. However, they can be field fabricated.
By John from New Hampshire on February 13, 2014
I was just told by an installer from a major oil/propane dealer in New Hampshire that as of about 5 years ago it became illegal to install a wood furnace into existing forced hot air ductwork. I was thinking of buying a wood furnace for our cellar - such as the one above - and wondered if I could do that ?
By Collin C. - NFI Master Hearth Professional on February 13, 2014
While this is not true on a national scale yet, more and more states and municipalities are adopting EPA Phase II guidelines that will make these unit illegal for use, unless the manufacturer came make them comply with the stringent emissions regulations in place. CA, OR, WA are all states that only allow Phase II appliances to be installed. Many areas in the northeast will not allow these products to be installed either and that may be what the installer was referring to.
We are located in Memphis, TN and as of now, there are not regulations being enforced on wood burning fireplaces in our area. However, it is likely that the EPA guidelines will eventually be enforced on a national level, with compliance mandatory.

I'm looking to buy the hot blast furnace 1557M for my manufactured home and wondered if anyone has had problems hooking up to a manufactured home's downdraft duct work. Is there a reason you can't hook to a manufactured home's duct work?
By Collin C. - NFI Master Hearth Professional on February 13, 2014
Unfortunately, the US Stove furnaces are not tested and listed for use in a manufactured or mobile home. While there is technically not an issue with the furnace working in this sort of downdraft application, it will not meet code. Appliances must be tested separately for use in stick built and manufactured housing. Many manufacturers delay their testing for manufactured homes or do not test at all, as there is generally less demand.

Is this wood stove ul approved?
By Collin C. - NFI Master Hearth Professional on April 26, 2012
This furnace is indeed approved under the following standards:
ANSI/UL 391 & CAN/CSA-B366.1-M91
It has also been tested and certified by the Warnock Hersey agency.

What is the burn time on the wood furnace?
By Collin C. - NFI Master Hearth Professional on February 27, 2012
Per the manufacturer, the expected burn time of this furnace is between 7-10 hours.
Quality and type of wood used, venting setup, and personal experience with this type of product will affect the burn time of the stove.
By Renee from Charlottesville, VA on June 13, 2014
Can the furnace be used as a free standing wood stove and not connected to ducts?
By eFireplaceStore on June 13, 2014
The furnace can be utilized in this way, but it is highly recommended that you only attempt this kind of installation in a large, open floor plan, such as with a basement. The high output of the furnace could rapidly overheat divided floor plans.

I would recommend this item to a friend.
I purchased this wood burner to use as primary heat for my house. It has not yet got down below zero but I have seen some high 20 degree nights and just using this as my heat source I can keep a steady 75 degrees give or take. However, this is not my first stove and I will say you need to be very picky on the wood you burn in it in order to get good and long burns, and you need to burn large loads. My house is new built, 1600 sq feet, 2 story. Furnace is located in garage tied into my HVAC unit. House is very well insulated. So taken my experience and with using this as primarily my heat 24-7 I would rate it 4 stars. Heats good and close to great, have to keep up on great wood, takes up very little space and is easy to maintain.
Cons- door latch needs tightening every other day, not capable of using hot water coil adapter.
Happy with how it performs at this point, kinda nervous about teens or below zero temps, I think then I might have to have hvac help out some.I would recomend it to others, but if your like me I would go bigger next time.
Overall good not perfect, but good. Happy with what I got for what I paid. Very happy with this store.
Walmart can make a better door latch. Have to burn very high btu wood to get warmth in home above 70 degrees.
