This ¿ replace will operate correctly only if adequate ventila-
tion is provided to allow proper draft to the ¿ replace system.
Hearth & Home Technologies assumes no responsibility for
the improper performance of the
¿ replace system caused
by inadequate draft due to environmental conditions, down
drafts, tight sealing construction of the structure, or mechan-
ical exhausting devices which will create a negative air pres-
sure within the structure where the
¿ replace is located.
A. Understanding Vent Problems
If smoke spillage occurs from a ¿ replace opening when the
door is open and the proper chimney height, À ue size, and
con ¿ guration requirements for the installation have been
met, there is either a leakage in the À ue, a blockage in the
À ue, or some condition is in effect to draw smoke from the
¿ replace into the house. Understanding and differentiating
the conditions which can cause each of these kinds of spill-
age problems is essential to their solution.
• Flue Leakage
Check for improperly connected À ue joints or a damaged
À ue joint in the chimney system. Such leakage would
reduce draft (air would be drawn in through the leaks rather
than through the
¿ replace). The result might be dif¿ cult
start-up and smoky ¿ res that might spill if other adverse
draft conditions accompany this problem.
• Flue Blockage
The damper should be open.
