TDVDSN Series Direct Vent Gas Fireplace
20007890
A hearth is not mandatory but is recommended for  
aesthetic purposes.  We recommend a noncombustible 
hearth which projects out 12” (305 mm) or more from 
the front of the fireplace.
Cold climate installation recommendation:  
When installing this unit against a non-
insulated exterior wall or chase, it is 
mandatory that the outer walls be insulated 
to conform to applicable insulation codes.  
NOTE: Never allow vapor barrier to contact the 
outer casing of this fireplace or venting.
Hearth
Noncombustible materials such as brick or tile may be 
extended over the edges of the face of the appliance. 
DO NOT cover any vent or grille panels.
If a Trim Kit is going to be installed on the fireplace, the 
brick or tile will have to be installed flush with the edges 
of the appliance.
Final Finishing
Framing and Finishing
1.  Choose the unit location.
2.  Place the unit into position and secure it to the floor 
with 1¹⁄₂” (38 mm) screws, or nails. The holes to 
secure the unit to the floor are located just behind 
the access door grille on the left and right side of the 
unit. 
3.  Frame in the fireplace with a header across the top. 
It is important to allow for the finished wall face when 
setting the depth of the frame.
4.  Attach the fireplace to the frame using the adjust-
able frame drywall strips (located behind the access 
door for shipping). Preset the depth to suit the facing 
material of the wall. The strips are adjustable to 1/2” 
(13 mm), 5/8” (16 mm) or 3/4” (19 mm). (Fig. 4)
5.  Screw through the slotted holes in the drywall strip 
and into the pre-drilled holes in the fireplace side. 
Measure from the face of the fireplace to the face of 
the drywall strip to confirm the final depth.
