MF series
The MF-Series stoves are the most
popular design on the market
today. The shaker grate and ash
drawer system make firebox
maintenance as easy as putting
garbage in a barrel while the
rear-air blower ensures a complete
burn as the air is blown under the
grates to the base of the fire. These
furnaces burn wood, coal and cob
corn and are extremely easy to use.

Boiler Treatment Policy
Water must be tested a minimum of once per year and boiler treatment added when necessary.
Each year a reminder card will be sent to test your water. To test the water, fill one of the test bottles provided free with your stove and mail to our testing lab
using the mailing carton and label provided with the bottle. If any adjustments need to be made to the water you will receive a report outlining what must be
done. Take another sample and mail it to our test lab again to verify the recommended changes have been made. Most times the recommended changes are
simply add water treatment or add water to have the water at the recommended operating levels (See the nitrate and pH test pages in the back of the manual
for test details.). Test bottles are provided free for the life of the furnace through your dealer or SteelTech Inc. offices.
Add the boiler treatment through the fill pipe located at the top of the furnace when initially filling the furnace with water or after testing, if needed. Ensure that
all the drains are closed. It is recommended that water treatment be added at 1 quart per 150 gallons of water initially and 1 quart per 200 gallons of water per
year after that. Additionally treatment may have to be added for water with more severe properties or for systems with more chemically demanding
requirements.
Recommended operating pH level is 9-10. Recommended nitrite levels are 600-1000 ppm. You can use test strips and the charts in the back of the manual if
you would like to test the water more then once a year. Test strips and information are available through your local dealer or through SteelTech Inc.
