FURNACE - PRIMARY FIRE 

 
DETERMINING THE APPROPIATE FIRE SIZE 
 
NOTE: DO NOT completely fill the firebox as this may cause an over-firing situation if there is not 
enough heat demand in the areas being serviced by the furnace. 
 

The WinterGreen Furnace uses less wood than a normal wood burning appliance.  It in turn needs less 
wood to produce a similar heat output. 

A medium intense fire is preferable to a large smoldering 

one to reduce the amount of creosote disposition. 
 
ENSURE DRAFT INDUCER IS TURNED ON. 
 
After the furnace has completed its start-up fire and burned the initial logs that were placed in-
side the firebox, then proceed as follows: 

1.  Partially open the firebox door, wait a few seconds then open it completely. Add 2 – 3 medium 

pieces of wood to the fire. 

2.  Wait approximately 10 – 15 minutes and periodically check the furnace. Watch how quickly the tem-

perature rises on Digital Temperature Controller. Check to see if the air intake damper is OPEN or 
CLOSED. 

 

Damper closes 

– and the digital readout indicates approximately 180˚F, then the furnace does not re-

quire any more wood. 
 

Damper is remaining open 

and the digital readout is below 180˚F and the controlling (House) thermo-

stat is not reaching temperature, add another small quantity of wood. 
 
Repeat step 2 until the furnace reaches 180˚F and the air intake damper closes. 
 
  

Observations: 
 

The furnace temperature will continue to rise after the air intake damper closes and the fire is extin-
guished. The rise should be to between 180˚F and 185˚F. Stabilization will occur at approximately 185˚F 
and temperature will begin to fall. The air intake damper will open and close regularly as the furnace 
modulates its internal temperature. 
 

Normal Operating Temperature 

Normal operating temperature can be verified by observing the Digital Readout on the Temperature 
Controller. It should read greater than 155˚F. The ideal temperature range is between 165˚ and 180˚F. 
 

Or 

There will be very little opaque smoke coming from the chimney while the furnace is operating. The 
smoke will become clear as the fire gets hotter. 
 

Or 

Yellow and bright yellow flames can be observed through the intake damper or by looking inside the fire-
box. 
 

Observe the furnace temperature of the unit relative to the quantity of wood that is loaded into 
the firebox. Understanding the relationship between this temperature and wood is important as 
to the proper loading of the furnace.
