LDVT Series Direct Vent  Gas Fireplace
10007852
A hearth is not mandatory but is recommended for  
aesthetic purposes.  We recommend a noncombustible 
hearth which projects out 12” (305mm) 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.  
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.

Check fireplace to make sure it is levelled 
and properly positioned.
To mount the appliance:
1.  Choose the location.
2.  This unit comes with four (4) flanges pre-mounted 
on both sides of the fireplace to allow two different 
drywall thicknesses to be used. Flange “A” is for 
1/2” drywall while flange “B” is for 5/8” drywall.
3.  Bend the desired flanges out 90° on both sides of 
the fireplace. Slide the fireplace into the framed 
opening until the flanges contact the front surfaces 
of the framing. Level the unit and secure it firmly in  
place.
