B. Design and Installation Considerations
NOTICE: Checkbuildingcodespriortoinstallation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult insurance carrier, local building inspector, re
ofcials or authorities having jurisdiction over restrictions,
installation inspection and permits.
• Before installing, determine the following:
- Where the replace is to be installed.
- The vent system conguration to be used.
- Gas supply piping.
- Electrical wiring.
- Framing and nishing details.
- Whether optional accessories - devices such as a
fan, wall switch or remote control - are desired.
1. Selecting Fireplace Locations
This replace may be used as a room divider. See Figure
2.2.
Locating the replace in a basement should be avoided.
Locating near frequently opened doors, central heat
outlets or returns, or other locations of considerable air
movement can affect the performance.
Outside air is recommended for combustion. This replace
comes equipped with an outside air inlet to feed combus-
tion air from outside the home, along with an outside air
termination cap; the duct is required but not supplied. Con-
sideration should be given to these factors before deciding
on a location.

VCG Designer Series • DSR42 Installation Manual • 4012-134 • Rev A • 02/20/15
2. Locating Fireplace & Chimney
Location of the replace and chimney will affect perfor-
mance.
• Install within the warm airspace enclosed by the building
envelope. This helps to produce more draft, especially
during lighting and die-down of the re.
• Installing the replace in a basement is not recommended.
• Penetrate the highest part of the roof. This minimizes
the effects of wind loading.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
• Minimize the use of chimney offsets.
• Consider the replace location relative to oor and ceiling
and attic joists.
• Take into consideration the termination requirements in
Sections 4 and 5.
Marginal Location:
• Below peak
Location NOT recommended:
• Not the highest point of the roof
• Wind loading possible
Multi-level Roofs
Windward
Leeward
Recommended Location:
• Above peak
Recommended:
• Insulated exterior chase
in cooler climates
Recommended Location:
• Above peak
• Inside heated space
Location NOT recommended:
• Too close to tree
• Below adjacent structure
• Lower roof line
• Avoid outside wall
Marginal Location:
• Wind loading possible
Figure 2.3 Recommended Chimney Locations
• Install the outside air kit with the intake facing prevailing
winds during the heating season.
• Ensure adequate outdoor air for all combustion
appliances and exhaust equipment.
• Ensure furnace and air conditioning return vents are not
located in the immediate vicinity of the replace.
• Avoid installing the replace near doors, walkways or
small isolated spaces.
• Recessed lighting should be a “sealed can” design.
• Attic hatches weather stripped or sealed.
• Attic mounted duct work and air handler joints and seams
taped or sealed.
