3.Determine the location for the air register/fan housing as- sembly. Cut a 127 x 346 mm hole between framing members (wall studs or floor joists).

4.Mount and secure the fan housing assembly to framing members so the front surface is 6 mm below the fin- ished wall or floor surface. Use the adjustable mounting brackets and screws provided in the kit. See Figure 4. NOTE: The brackets can be rotated 180º and mounted to the back side of the 2 x 4 if necessary.

5.Install the air duct run. NOTE: Fold outer poly layer of flexible duct back to maintain clearance to combustibles on the fireplace. Secure liner to the collar with clamp.

ROUND and OVAL DUCT: A combination of 152 mm round and 152 mm oval air duct can be used in the duct run. Oval duct components must be purchased from a heating or air conditioning ventilation supplier.

NOTE: Support duct at intervals of no greater than four feet with no more than 1/2 in. sag between supports or as required per local code. Secure the duct so that clearance to the outer wrap of the fireplace is maintained.

6.Install a wall switch in a convenient location. This switch will control the HEAT-ZONE-240V fan operation. When using the AUX300CE in the IPI Plus system, the AUX1 or AUX2 can control the output and ON/OFF function in place of a separate wall switch. Note that the RC300 remote is needed.

7.Wire 240 VAC service TO the wall switch and FROM the wall switch to the fan junction box. Use wire connectors to secure the 240 VAC service wires to the hot and neutral fan wires and screw the 240 VAC ground wire to the fan junction box. See Figure 8 for isolated control wall switch. See Figure 9 for IPI Plus with auxiliary control.

8.Screw the fan junction box to the fan housing.

9.Screw the register adapter frame and the air register to the fan housing. See Figure 7.
