TC42 Steel Stud Framing Kit

1. Top Frame Assembly
Lay out the horizontal header stud (Item #5 in Figure 1) on a large at surface. (Position all pieces on
their narrow edges as shown in Figure 1.
2. Attach Side Studs (Legs)
Lay the inner vertical side studs (Item #2 in Figure 1) so that it’s top end aligns with the 2nd set of
screw holes of the header stud (Item #5 in Figure 1). Fasten with screws provided.
Fasten the vertical outer side studs (Item # 3 in Figure 1) to the ends of the horizontal header stud
(Item #5 in Figure 1).
Position the base plates (Item #7 in Figure 1) at the bottom of the inner and outer side stud legs and
fasten with the screws provided.
Turn the assembled frame over and install screws to the remaining fastening points.
3. Attach Lower Venting Box to steel frame
Align and secure the Lower Venting Box to the steel frame with provided hardware prior to mount-
ing the steel frame and Lower Venting Box onto the TC42. See “Mounting the Lower Venting Box to
Steel Frame” on page 6.
4. Attach the Assembled Frame with the Lower Venting Box to the Unit
Align the assembled frame and Lower Venting Box to the TC42 and attach to the framing brackets
(Items #8 in Figure 1). Align the framing brackets to the fastening points through the access holes in
the outer side studs (Item # 3 in Figure 1).
5. Secure to Lumber Framing using four framing tabs
Bend the (four) framing tabs out and use to secure the steel frame assembly and the TC42 to the
lumber framing through the horizontal top header and the base plates (Items #5 & 7 in Figure 1).
6. Install Facing Material.
Install Facing Material according to the requirements described in “Distribution of Facing Material”
on page 14.

Figure 4: Lower venting box attached to the steel
frame.
With the steel frame completed (Figure
2), mount and secure the Lower Venting
Box to the frame (Figure 3) using
supplied hardware.
When the Lower Venting Box is secured
to the steel frame, the front of the
Lower Venting Box will have an open
cavity exposed. This cavity will be
enclosed once the Non-combustible
facing material is installed (Figure 4).

Mounting the Lower Venting Box to Steel Frame

Knock-outs (2 rows)
Ports
There are 2 rows of knock-outs (Figure 6) on the TC42 xed Lintel. Only one of these rows will have
their knock-outs removed to accommodate the Lower Venting Box (Figure 5). Which row is removed
depends on where the steel frame is positioned over the TC42 Lintel and the 1/2 inch (minimum)
thickness requirement of the facing material.
If the steel frame is positioned so that the Lintel protrudes from the steel frame to its maximum,
then the rear set of knock-outs will be removed. If the steel frame is positioned so that the Lintel
protrudes minimally from the steel frame, then the front row of knock-outs will be removed.
Note: Be sure of the final placement of the TC42 and its steel frame before deciding on which
row of knock-outs are to be removed.

TC42 Lintel Knock-outs

Afx the Steel Frame (with the attached Lower Venting Box) to the TC42 using supplied hardware.
Once the steel frame is afxed to the TC42, the entire unit may then be adjusted into its nal
position. The installer must keep in mind that the lumber framing will be built around the steel frame
and the TC42 and so accurate positioning of the unit before construction of the lumber frame is
critical.

Lower header for upper grill
Steel frame
Conventional lumber frame
Lower venting box
Distance between upper grill &
lower vent depends on length
of flexible ducting. Length of
ducting is from 3 feet min. to 5
1/2 feet maximum.
Figure 8: Building the lumber frame around the steel frame.
Once the TC42 and its attached steel frame is in its nal location, the lumber framing can be built.
A smaller frame must be built into the lumber frame to accommodate the Upper Grill (Figure 8) but
only the bottom horizontal header should be installed at this time.
The Flexible Ducting supplied comes in 3 foot lengths which can be stretched to approximately
5 1/2 feet to allow more distance between the Upper Grill and Lower Venting Box. This allows for
the installation of various sized television sets or other forms of wall hanging. It is necessary when
calculating the nal position of the Upper Grill, to consider where both ends of the Flexible Ducting
will attach to the Upper Grill and Lower Venting Box.

Mounting the Upper Grill
When constructing the lumber frame around the steel frame, secure the bottom header for the Upper
Grill to the lumber frame but do not install the upper header (Figure 9). The Upper Grill will t over the
bottom header and can be secured at this time using the supplied hardware.
Once the Upper Grill is secured to the bottom header, the upper header can then be tted over top
of the Upper Grill and secured to the lumber frame (Figure 10).
After the Upper Grill has been installed, the lumber frame can be completed (Figure 11).

Installation of Fireplace Venting
The Fireplace Vent can be installed at this time (Figure 13). It may be necessary to remove the front
stand-offs if they interfere with the routing of the exible ducting.

Distribution of Facing Material
Figure 14: Combustible & non-combustible zones for facing material.
Combustible and non-combustible facing material may now be installed. Refer to Figure 14 for
distribution of facing material. The area above and on either side of the TC42 within the steel frame
must (grey area) use Non-combustible facing material. The area outside of the steel frame may use
Combustible facing material (Dotted area).
It is important to note that all facing material must be a minimum of 1/2 inch thick. The thickness of
the facing material must be calculated into the nal position of the TC42 and its steel frame.

Venting Near the Ceiling
If desired, the Upper Venting Box may be placed as close to the ceiling as it is possible (Figure 15).
It is not necessary for the ceiling to be made with non-combustible material. The heat expelled from
the Upper Venting Box is not high enough to damage the ceiling material.
Do not place combustibles such as electronics or artwork within the rst 48” from the oor.
