6.2 Mechanical Draft System for Wood-red
Fireplace with Multiple Flues
Application
This is used in the same situations as System 1, but
where multiple fans are required to handle the heat
load. It is a typical installation for large replaces
where a single ue cannot handle the amount of
exhaust gases generated.
*For one fan serving two ues please refer to section
6.1 as the wiring diagram is identical. A special
plenum box may be required.
Sequence of Operation
The sequence of operation is no different from
System 1, but make sure a single fan speed control
is simultaneously handling both fans.
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 speed again.
6. When the re is dying, reduce the speed setting
further to remove remaining products of
combustion.
Please see important note on page 24.
