Outside air requirements 
 
Required for mobile home and in certain localities (Check with building officials) 
Outside air must not be drawn from an enclosed space (garage or other unventilated spaces) 
When using outside air, find a location where the chimney and outside air hole do not interfere with structural members 
of the home. 
Connect a 4" (100 mm) diameter stainless steel or other non-combustible corrosion resistant material, to the O.S.A hook-
up box. 
Run the pipe to the outside avoiding sharp bends and turn the end down and fit a corrosion resistant mesh to prevent the 
entry of leaves and rodents, seal all the penetration of the outside wall. 
 
   
                                                                                    
 
 
 
 
Draft Requirements 
SCAN stoves are only one component of the total system. The venting system is equally important 
for achieving the required flow of combustion air to the firebox and for safely removing unwanted 
combustion by-products from the appliance. If the venting system’s design does not promote these 
ends, the system may not function properly. Poorly functioning venting systems may create 
performance problems as well as become a safety hazard (i.e. an oversized chimney may result in 
less than optimum performance. Installations into a large, masonry chimney may require a liner to 
improve performance). A draft test should read greater than .04" W.C. (Inches Water Column) and 
less than .08" W.C. The table below shows the dimension of the connection piece as well as data 
for the draft requirements for the stove:

The chimney draught depends on the weather conditions. In stormy weather, you may reduce the 
chimney draught by closing the damper in the smoke pipe (if a damper has been installed). If the 
chimney draught is strong, the combustion air supply must be reduced additionally.
