To be sure that your stove burns properly, the chimney draft 

(static pressure) should be approximately -.04” water column 

(W.C.) during a low burn and -.10” W.C. during a high burn, 

measured 6 inches (152mm) above the top of the stove after 

one hour of operation at each burn setting.

NOTE

:  These are guidelines only, and may vary somewhat 

for individual installations.
The stove was designed for and tested on a 6 inch (152mm) 

chimney, 12 ft.-14 ft. (360-420cm) high, measured from the 

base of the stove.  The further your stack height or diameter 

varies from this configuration, the possibility of performance 

problems increases.  In addition, exterior conditions such as 

roof line, surrounding trees, prevailing winds and nearby hills 

can influence stove performance.
A masonry chimney or a listed factory-built UL103 HT Class 

“A”  chimney  must  be  the  required  height  above  the  roof 

and any other nearby obstructions.  The chimney must be 

at least 3 ft. (91cm) higher than the highest point where it 

passes through the roof and at least 2 ft. (61cm) higher than 

the highest part of the roof or structure that is within 10 ft. 

(305cm) of the chimney, measured horizontally.  

See 2-10-3 

Rule below.
These  are  safety  requirements  and  are  not  meant  to 

assure proper flue draft.

We recommend using a minimum total system height of 12 

ft. (360cm), measured from the flue collar to the top of the 

chimney (not including chimney cap).

(305cm)

2-10-3 RULE

A proper amount of flue draft is required to assure the safe 

and efficient operation of the this woodstove.  Flue draft is 

measured as negative pressure in the chimney.  The amount 

of negative pressure determines the strength of the draft.  

This draft performs two important roles in the operation of 

the woodstove.   It draws the combustion air into the firebox, 

and pulls the smoke out of the chimney.

Three factors work together as a system to create the flue 

draft;  1)  availability  of  combustion  air;  2)  heat  generated 

from the fire, and 3) diameter and height of the flue system..  

Increasing  or  decreasing  any  one  of  them 

will 

affect  the 

other two and thus change the amount of draft in the entire 

system.  
A source of air (oxygen) is necessary in order for combustion 

to take place.  The combustion air enters the firebox below 

the ash catcher and is directed to the upper front of the fire-

box.  These openings are regulated by the Primary Air Slide 

Control and  Start-up Air Control, (see 

page 17 

for operation 

of these controls).  It is important to realize that whatever 

combustion air is consumed by the fire must be replaced.  

If you are using room air, the air is replaced via air leakage 

that occurs around windows and under doors, etc.  However, 

in most newly constructed houses, mobile homes, or even 

existing homes that are fitted with tightly sealed doors and 

windows, the area from which the combustion air is taken 

is relatively air tight.  In these cases, an outside air source 

must be made available to feed combustion air from outside 

the home into the stove.  An Outside Air Kit is available as 

an option, Part 831-1780.  The kit is a requirement for mobile 

home installations.  
A  specific  volume  of  air,  determined  by  the  diameter  and 

height of the chimney connector and chimney, is contained 

within the flue system.  As heat from the fire enters the flue, 

it warms this air causing it to rise.  The air moving up the 

flue draws smoke and more heated air from the fire with it, 

thus establishing draft.  The amount of draft depends on the 

temperature of the heated air and the volume of air that is 

contained in the flue system.
If the fire is difficult to start, and smoke spills out of the door, 

or you find it hard to establish and maintain a moderately 

high burn rate, then the flue draft is too low and corrective 

measures must be taken.
If you still suspect you have a low draft problem, it may be 

necessary to increase the volume of air in your flue system.  

Since the diameter of your flue system is matched with the 

size of the flue collar and should not be changed, the height 

of the system will need to be increased. Add chimney a little 

at a time until the draft improves, and ensure that the flue 

collar and venting section are sealed.
Your local dealer is the expert in your geographic area and 

can usually make suggestions or discover problems that will 

easily correct your flue draft problem, allowing your wood-

stove and its flue system to operate correctly and provide 

safe and economical heat for your home.
