D. Locating Your Appliance & Chimney
Location of the appliance and chimney will affect perfor- mance. As shown in Figure 28.1 the chimney should:
•Install through the warm space enclosed by the build- ing envelope. This helps to produce more draft, espe- cially during lighting and die down of the fire.
•Penetrate the highest part of the roof. This minimizes the affects of wind turbulence and down drafts.
•Consider the appliance location in order to avoid floor and ceiling attic joists and rafters.
•Locate termination cap away from trees, adjacent structures, uneven roof lines and other obstruc- tions.
Your local dealer is the expert in your geographic area and can usually make suggestions or discover solutions that will easily correct your flue problem.
