Heatilator EL36 Series Owner's Manual page 6

Location of the fi replace and chimney will affect performance.
As shown in Figure 2.1 the chimney should:
• Be installed through the warm airspace enclosed by the
building envelope. This helps to produce more draft,
especially during lighting and die-down of the fi re.
• Penetrate the highest part of the roof. This minimizes the
effects of wind turbulence.
• Be located away from trees, adjacent structures, uneven
roof lines and other obstructions.
Offsets can restrict draft so their use should be minimized.
Consider the fi replace location relative to fl oor and ceiling
and attic joists.
