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.
