Empire Comfort Systems White Mountain Hearth DVCX42FP91K-3 Installation Instructions And Owner's Manual page 17

Attention: Cold climate installation recommendation: When
installing this unit against a non-insulated exterior wall, the outer
walls should be insulated to conform to applicable codes.
Finish the joint between the fireplace and wall with sealant rated
at 300 degrees F, or tile/stone over the joint.
Vent Runs
In planning the installation for the fireplace, it is necessary to install
certain components before the appliance is completely positioned
and installed. These include the direct vent system, gas piping for
the appliance and the electrical wiring. (If the fan option is used.)
The appliance can be mounted on any of the following surfaces:
1. A flat, hard combustible (burnable) surface.
2. A raised wooden platform.
3. Four corner supports. (Example: Four concrete masonry blocks.)
These supports must be positioned so they contact all four
perimeter edges on the bottom of the unit.
Securing the Vent Pipe to the Fireplace
1. Hand bend the tabs up on the Outer Wrapper Top Assembly
as shown in Figure 20.
2. Insert the first piece of pipe and secure with 4 screws through
the tabs and into the pipe. See Figures 21 and 22.
