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

MF 3000
The MF-Series furnaces are one of the most
popular designs on the market today. Rolling
door handles,  easy-to-see water level float,  
shaker grates, ash-pan, round 10 gauge 409
stainless steel firebox and water jacket all
combine to create the most user-friendly and
durable furnace available.  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 require minimal maintenance.
