This fi replace will operate correctly only if adequate ventila-
tion is provided to allow proper draft to the fi replace system.
Hearth & Home Technologies assumes no responsibility for
the improper performance of the fi 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 fi replace is located.
A. Understanding Vent Problems
If smoke spillage occurs from a fi replace opening when the
door is open and the proper chimney height, fl ue size, and
confi guration requirements for the installation have been
met, there is either a leakage in the fl ue, a blockage in the
fl ue, or some condition is in effect to draw smoke from the
fi 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 fl ue joints or a damaged
fl ue joint in the chimney system. Such leakage would
reduce draft (air would be drawn in through the leaks rather
than through the fi replace). The result might be diffi cult
start-up and smoky fi res that might spill if other adverse
draft conditions accompany this problem.
• Flue Blockage
The damper should be open.
