6. Guide for Mechanical Draft Systems
There are a number of different ways to use
mechanical venting systems. The following presents
a variety of these applications.
6.1 Mechanical Draft System for Wood-Fired
Fireplace with a Single Flue
Application
This is the most common form of installation and is
used in all jurisdictions where the 2000 or later
edition of the NFPA211 has not yet been adopted.
Sequence of Operation
1. Prepare the wood logs in the replace.
2. Turn the Fan Speed Control (FSC) on by turning
the knob clockwise. A “click” indicates the control
is turned on. Adjust the knob to the desired
speed.
3. Start the re by igniting the logs.
4. Once the re is fully burning, turn the
dial clockwise (to reduce the speed) until there is
spillage coming from the replace opening.
Hot, moist heat rising from the top of the replace
is an indication of spillage. From this point,
gradually increase the fan speed by turning the
dial counter-clockwise until no ue gases spill
from the replace. The dial can be left in this
position.
5. If logs are added to the re, it may be necessary
to increase the fan speed again.
6. When the re is dying, reduce the speed setting
further to remove remaining products of
combustion.

IMPORTANT NOTE:
Never leave a re unattended. When a re is
smoldering it is more likely to emit carbon
monoxide.
You should always have a smoke detector
and a carbon monoxide detecter installed in
the same room where the solid-fuel burning
appliance is installed.
