blower is installed beneath the firebox. Room air is drawn in through the
bottom area of the fireplace, heated as it passes across the firebox, and
discharged through the upper panel/louver area at the top of the
fireplace. This kit contains one blower, one speed control module, two
speed control module securing screws and these instructions.
INSTALLATION INSTRUCTIONS
Step 1. Turn off the fireplace and allow it to cool before proceeding.
Step 2. If the appliance is connected to 120 volt power, disconnect
the power.
Step 3. Shut off the gas supply to the fireplace.
Step 4. Open the lower compartment door (either a radiant panel or
louver assembly) by pushing in simultaneously the left and right side of
the door. (The door is hinged at the bottom.)
Step 5. D-400, D-500, D-600 and D-800 series; B-500, B-600, and
B-800 series; and MDT3328 and MDR3328 Fireplaces - Remove the
bottom panel or louver assembly by removing the screw at each end of
the panel or louver assembly, retain the end spacers, and then pull the
panel or the louver assembly from the unit.
Elite-2 Series Fireplaces - Remove the bottom compartment door (on
Multi-Open fireplaces, the modesty-panel-side door) by sliding the
hinge pin, located at the door's left side, to the right until it disengages
from the left corner post hole. Pull the door diagonally to the left, away
from the fireplace.
Step 6. Elite-2 Series Fireplaces - Remove the modesty panel as
follows: lift the modesty panel by the tab on the panel's right end, pull
the right end of the panel away from cabinet and then pull the panel
diagonally out of the corner post slots on the left side of the unit. Remove
the modesty panel carefully, so that none of the wires become loose or
disconnected.
Step 7. Front-open direct vent and B-vent units -
Slide the blower assembly through the front opening to the middle rear
area of the cabinet base. Position the blower assembly so that the tabs
(located on the cabinet base) are seated in the notches of the blower
