If you encounter any problems, need clarification of these instructions or are not qualified to properly install this kit, contact your local distributor or dealer.
Read this instruction sheet in its entirety before beginning the installation.
ALL WARNINGS AND PRECAUTIONS IN THE INSTALLATION AND OPERATION MANUAL PROVIDED WITH THE APPLIANCE APPLY TO
THESE INSTRUCTIONS.
SHUT DOWN THE APPLIANCE AND ALLOW IT TO COMPLETELY COOL
BEFORE PROCEEDING.
Features of the forced air system
Installation in Another Room

• Allows for warm air distribution to another room.
• Can install up to 50 feet (15.2 m) of flexible pipe.
• Can provide warm air distribution to a basement, garage or attic.
• Possibility of controlling via a wall thermostat.

Components for the Connection Kit for Forced Air System

The starter kit is comprised of a variable speed blower (BISZY), an adaptor for flexible pipe (BISAF), blower to flexible pipe adaptor (BISAVF), a variable speed control for the blower (VRUW) and a thermostatic control (VTU). The following optional parts are also available: wall thermostat with control box (HCTW) and a back draft damper (BISBD).

MECHANICAL INSTALLATION

step 1. Locate the warm air outlet, make sure it respects the maximum distances, plan for the passage through walls, ceilings etc., when mapping out the path the duct will take.
step 2. Locate the area where the flexible pipe will hook up to the appliance.
step 3. Removethecorresponding5-inchplate,cuttheinsulationfollowingtheholediameterandscrewintheflexiblepipeadaptor (Figure 1). These plates are located in the following places:

•  On the Solana™, HE43-2 and SE36 fireplaces, on the upper left and right hand sides of the unit.
• On the Brentwood™ SP, BIS ®  Ultima-1, WCT4820WS,  Brentwood LV, BIS Ultima CF, WRT4820WS, Montecito™, BIS Tradition CE, WCT6820WS, Villa Vista™, BIS Panorama, WRT4826WH, Montecito Estate™, BIS Tradition, WCT6840WS, Ladera™,BISNova,WRT3820WS,Cambria™,LeLaval™and BIS Ultra fireplaces, on the upper left and right hand sides as well as the back of the unit.

step 4. Using a tightening collar, install the flexible pipe to the adaptor (Figure 3). CAUTIOn: make sure the plastic casing of the flexible pipe does not touch the fireplace.

step 5. Bring the flexible pipe to the desired room; this room may be located on an upper or a lower floor. Please note that the maximum allowable length of flexible pipe is 50 feet from the fireplace. Seeing that the pipe is insulated, it may be installed with zero clearance to combustible materials.
step 6. To install the blower, place the four (4) anti-vibration rubbers in the holes of the support plate of the blower and screw the blower to a solid base. The blower may be installed either horizontally or vertically but must be easily accessible for maintenance as well as for the electrical installation (Figure 4).
step 7. With the second tightening collar, install the flexible pipe to the round central inlet of the blower (Figure 4).

step 8. Installtheflexibleadaptor(BISAVF)tothesquareoutletofthe blower using four self-tapping screws and use a tightening collar to install the pipe (Figure 7).Bringthesecondflexiblepipeto the warm air distribution outlet.

• Purchase,fromyourhardwarestore,anadapterfromø5in. flexible pipe to any chosen air distribution outlet.
• Install the pipe with a tightening collar.

Thermostat
If you are using a thermostat, install it in the room where the warm air is being sent. It is preferable to install the thermostat at the opposite end of the room so that the thermostat is not in direct contact with the warm air. Do not install the thermostat in the same room as the fireplace unless you are using it as a cooling thermostat. This may be useful to activate the fans to send the warm air towards another room once the temperature is too high in the room where the fireplace is installed (see Note for Installing a Cooling Thermostat).
Thermostatic Control
The thermostatic control (VTU) allows for the blower to work when fireplace temperatures reach a certain point. This control is easy to install: because of its magnets, all you need to do is place it on the bottom right hand side of the firebox (Figure 8).
NOTE: For visual purpose, the right side panel has been removed.

Electrical Installation

WARNING
All electrical connections and grounds must be in accordance with local codes and regulations, and, in absence of these, the CsA C22.1 Canadian code, or in the United states, the AnsI/nFPA 70 national electrical code.

1. In order to avoid electrical shock, all connections between 2 wires must be placed in a metallic box. It is preferable to use one electric conductor between each element of the system.
2. Unless otherwise indicated, every electrical wiring not supplied by the manufacturer must be 14-gauge minimum.
3. All electrical wiring coming in or out of the fireplace must pass through the fireboxes electrical box.

1. Basic Electrical Connection

For a basic electrical connection, use any terminal in the following order:
A. Install a standard 120V receptacle in the fireplace’s junction box.
B. Starting with the white wire provided in the starter kit, connect a wire to the terminal of the thermostatic control.
WARNING
In order to prevent electrical shock, completely finish and verify the connections of the electrical system before plugging it in.
C. Connect the second terminal of the thermostatic control (VTU) to one of the two wires of the variable speed control (VRUW).
D. Connect the second wire of the variable speed controls (VRUW) to the blower (BISZY).
E. Finally, from the blower (BISZY), go back into the fireplace and connect that wire to the black wire of the electrical plug.
F. Make sure that no wires are in contact with the hearth and that the whole system is safe prior to plugging in the wire.
2. Electric Connection with Thermostat

When installing a thermostat, you have received a control box including a transformer and a relay. This electrical box will allow you to make a 24V system that is parallel with the 120V system; it is essential that the following steps be followed in order to avoid an electrical surcharge on the system.

A. Install an electrical socket of 120V in the fireplace’s electrical box.
B. Open the cover of the control box. Connect the red wires of the control box to an insulated container with 18-2 wire minimum. The connections must be inside the control box. Pass the insulated conductor through the metallic grommet. Pass the conductor through the electrical box of the fireplace, and then connect the other end to the thermostat terminals.
C. Connect the black wire with quick connect to a terminal of the thermostatic control (VTU) (Figure 8).
D. From the second terminal of the thermostatic control, pass a single conductor wire, through the fireplace’s electric box up to a wire of the variable speed control (VRUW) (Figure 8).
E. From the second wire of the variable speed control (VRUW) to the blower (BISZY).
F. Finally, from the blower (BISZY), return to the fireplace and connect that wire to the second black conductor. The connection must be made inside the box.
G. Securely fasten the control box to the exterior of the fireplace (Figure 8).
H. Make sure that no wires are in contact with the hearth and that the whole system is safe prior to plugging in the wire.

3. note for Installing a Cooling Thermostat
In order for the thermostat to work as a cooling thermostat, you must:
A. Ensure that all connecting electrical sources with this system are unplugged.
B. Open the control box by removing the four screws on the side of the box.
C. Locate the wire connected to terminal #3 of the relay (the terminal numbers are etched in the relay box).
D. Disconnect this wire from the terminal #3 and reconnect it to the terminal

2 (Figure 12).

E. Ensure that no other wire was disconnected while completing this operation.
F. Close the cover of the control box.
NOTE: DIAGRAms & ILLUsTRATIOns ARE nOT TO sCALE.
IHP reserves the right to make changes at any time, without notice, in design, materials, specifications, prices and also to discontinue colors, styles and products. Consult your local distributor for fireplace code information
