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.

with a three-prong, grounding plug. The plug is your
protection against electrical shock. Plug it into a stan-
dard, three-hole, grounded, outlet. If cord needs re-
placing, use only a cord with a three-prong, grounding
plug.
•Failure to connect all wires as indicated may cause
electrical shock or personal injury.

WARNING
Reinstall any barrier removed before operating the fire-
place. The barrier is designed to reduce the risk of burns
from hot glass. Do not operate the fireplace without the
barrier installed.
CAUTION
Wear cut resistant gloves and protective clothing during
this process.
INSTALLATION INSTRUCTIONS
1. Turn OFF the fireplace and allow it to cool before proceeding.
2. If the appliance is connected to 120 volt power, disconnect the
power.
3. Shut off the gas supply to the fireplace.
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, or simply lower door down (some doors have hinge pins that
allow the door to be completely removed by pulling pins). Fireplaces
with facades will require the entire facade be removed.
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 bot-
tom 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.

the blower assembly through the closest opening to the flue side 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 bracket. Bend the
tabs over to secure the blower assembly. See Figure 2 for see-through,
peninsula or corner-left models; Figure 4 for corner right models.
8. If electrical power has not been provided to the unit’s junction box
receptacle - Route a 3-wire, 120 Vac power line to the unit’s junction
box. Remove the receptacle by removing the two securing screws.
Connect the supply wires to the receptacle as shown in Figure 10.
Reinstall the receptacle.
IMPORTANT: Ground lead must beconnectedtothegreenscrewlocated
on the junction box. Failure to do so will prevent the appliance from
operating. The appliance must be electrically grounded in accordance
with local codes or, in the absence of local codes, the National Electrical
Code, ANSI/NFPA 70-latest edition (In Canada, the current CSA C22-1
Canadian Electrical Code).

Figure 8 - DIRECT-VENT MODELS
10. Direct-vent units - Place the front lip of the control module under-
neath the front flange of the cabinet bottom panel as shown in View
A, Figure 8. Secure the module with the two (or one) kit-provided
screw(s).
B-vent units - There are two module mounting tabs located on the cabinet
base just to the left/front of the blower, as shown in Figure 3. Bend these
tabs up, 90 degrees. Place the control module behind the vertical tabs as
shown in Figure 3 and secure the module to the tabs with the two screws
provided in this kit.
11. Adjust the height of the thermal element sensing disk located on
top of the module so that it touches the underside of the firebox
floor in Direct-vent units, B-600/800 units and the firebox sub-floor
in B-500 units. To accomplish this, loosen the wing nut on the mod-
ule’s side, raise the sensing disk housing to the height required above,
then retighten the wingnut. See Figure 8, View A for direct-vent
units, see Figure 9, View A for B-500 units and Figure 9, View B for
B-600/800 units.
12. Plug the blower cord into the module and the module cord into the
top receptacle as shown in Figure 10.
13. Elite-2 Series Gas Fireplaces - Remove the control knob from the
module. See View A, Figure 8. Cut out the circular opening on the
modesty panel sticker that is reserved for the installation of the speed
control module. Reinstall the modesty panel carefully, so that none of
the wires become loose or disconnected. Reinstall the control knob,
then Reinstall the modesty panel. Reinstall the modesty panel care-
fully, so that none of the wires become loose or disconnected. If your
fireplace is not an Elite 2 series, please move to Step 14.
