Thermostat Control & Pilot Settings

The Furnace may be controlled with a thermostat to help maintain a more constant

temperature. A Multi-Fuel furnace, such as the SCF 050, will be a little slower in reacting to

a thermostat than the typical Gas, Electric or Oil fired furnace. With this in mind we have

incorporated 3 Pilot settings on the control board (See Point 5 on Page 25). This will allow

the heat output during the pilot stage to be matched to the size of the home. A larger home

will require more heat than a small one. Keep in mind that the furnace is constantly

producing some heat that helps heat the home while the furnace is in pilot mode. If the home

seems too warm, and the Thermostat is never calling for heat, a lower pilot setting may be a

better fit for the home.

Remember: Choosing a lower Pilot setting may require the damper to be fine-tuned to

match the lower feed rate. Monitor how the furnace is operating after a change is made

and adjust the damper if needed.

SCF-050 MAINTENANCE

The St. Croix clinker theory. And why we do what we do.

Some manufacturers of multi-fuel Furnaces use complicated stirring mechanisms to break

up the clinker in the burn pot. We feel that is a mistake.

We believe that corn, wheat, rye or Distiller’s Grain pellets do not burn as well when it is

disturbed during the burn process. These fuels need high temperatures and proper airflow

in the burn pot to burn properly. That energy is stored in the clinker that is being formed

in the burn pot. It glows red-hot and provides the heat needed to ignite the corn, wheat or

rye that is being fed into the burn pot. When the clinker is broken up, that constant source

of energy is lost and now it becomes more difficult to burn these fuels. When corn,

wheat, rye and distiller’s grain is not burning properly it tends to stick together and form

a clump in the burn pot. It is impossible for air to flow through this clump and soon the

pot will overload and the fire goes out. This is where some manufacturers use the stirring

mechanism to break up the clump of fuel to maintain proper airflow and others use large

burn pots to handle this problem (Smaller burn pots are better). The truth is neither is

needed. The St. Croix burn system allows the corn, wheat, rye & distilller’s grain to be

burned efficiently and completely in a relatively small burn pot. Very little residue ends

up in the ash pan.

When burning Pellets or Cherry Pits in the standard pot in the furnace, ash will build up

in a similar manner as the clinker does when burning corn, wheat, rye or distiller’s grain.

The pot is maintained the same way as described in the following section covering the
