F. 2-10-3 Rule
These are safety requirements and are not meant to assure proper flue draft.
This appliance is made with a 6 inch (152mm) diameter chimney connector as the flue collar on the unit.
• Changing the diameter of the chimney can affect draft and cause poor performance.
• It is not recommended to use offsets and elbows at altitudes above 4000 feet above sea level and or when there
are other factors that affect flue draft.
