Rated 2 out of 5 by from Upset Asked before we ordered our King 8500 multi fuel pellet furnace if it had a auto igniter. Was told yes it did. Have it hocked up and started it up last night, guess what? It doesn’t. Now can I install one? Called US Stove and asked before we ordered more than once about the igniter

Rated 5 out of 5 by from Very efficient! We bought this furnace a little over a month about and put it into service the day it arrived. We burn straight field corn in ours(as long as its free of corn cobs) and it puts out a lot of heat and is very efficient. But if you burn straight corn like we do, you MUST remove the agitator. Otherwise it will break in about 3 days of use like ours did. Found out that its only needed if you burn anything else but straight corn. Then just clean out the "brick" that forms at the bottom with a metal pick once ever 12-15 hours depending on the moisture content. No need to turn off the furnace when doing so just use BBQ gloves. It also burns much cleaner with corn. I also recommend getting the burn pot extension but you can make your own if your handy with a welder like I did. Otherwise a lot of the fuel tends to bounce out of the pot as it slides down the channel. Make sure you set your furnace set up right as well. You can find lots of info online on how to set it up for your specific needs as well, much more then what your owners manual saids.

The Product Specifications on the Tractor Webpage says this stove weighs 500lbs with a massive 160 lb hopper. The manual on your website says it weighs 250lbs with a 320 lb hopper. Which is correct??

Asked by: LBESEE
500 lbs with the 160 lb hopper is correct.

we have a modular home on a full basement would this unit be a good fit for us

Asked by: DonnaJean
This would be able the heat the home if you tied into your existing duct.

If the hopper is in top, then how is it possible to be connected to your existing duct work, or don't you use a bonnet over the top of the stove for the duct work?

Asked by: Char64
The way that the opening for the plenum is designed, the plenum will come up as a rectangular opening and transition into a single 10in round in the front of the furnace, allowing the hopper lid to be opened behind it so the pellets can be loaded from the side.

Can this replace an existing GAS furnace with proper installation? Does this work with the thermostat in the house? Or do you physically have to go to the basement and turn it on & off? I really appreciate you reading this.

Asked by: Housewife
This unit can have a non digital 2 wire millivolt thermostat hooked into the control board. Depending on the distance from the stove to the thermostat will vary on the gauge of wiring. Depending on the square footage you are trying to heat, you are capable to replace a gas furnace using this pellet furnace. You will have to hook up P/PL vent exhaust and temperature rated duct work.

Is there a air filter integral to the stove ? Where is the return air ducted to the stove ? Comparing rice anthracite to wood pellets , which produces the better BTU output ? Thanks

Asked by: Anonymous
The return air intake is at the rear bottom of the furnace. It does have an integrated air filter slot. this is NOT DESIGNED for use with rice anthracite. Please do not use that. It is designed for wood pellets, corn and a few other Bio-fuels.
