To minimize the effects of negative air pressure, the follow-
ing must be considered:
• Install the outside air kit.
• Ensure adequate outdoor air is supplied for combustion
appliances and exhaust equipment.
• Ensure furnace and air conditioning return vents are not
located in the immediate vicinity of the fireplace.
• Avoid installing the fireplace near doors, walkways or small
isolated spaces.
• Recessed lighting should be a "sealed can" design; attic
hatches weather stripped or sealed; attic mounted duct
work and air handler joints and seams taped or sealed.
Location of the fireplace and chimney will affect performance.
As shown in Figure 7.1, 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 fire.
• 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 fireplace location relative to floor and ceiling
and attic joists.

7100FP EPA Woodburning Fireplace
The 7100FP Fireplace requires a minimum flue draft of -0.10
inches of water column on High, and -0.04 inches of water
column on Low, as measured with a draft meter. Most deal-
ers have draft meters available to measure your flue draft if
you suspect a problem.
If the fire is difficult to start, and smoke spills out of the door,
or you find it hard to establish and maintain a moderately
high burn rate, then the flue draft is too low and corrective
measures must be taken.
NOTE: Cold air infiltration can cause frosting on glass.
Asphyxiation Risk
Negative pressure can cause spillage of
combustion fumes and soot. Fire needs to draft
properly for safe operation.
