GENRAL INFORMATION/INSTALLATION REQUIREMENTS
LOCATING THE FIREPLACE
1) When selecting a location for your Gas Fireplace,
ensure that the clearances outlined in this manual are
adhered to strictly.
2) The fireplace must be installed on a flat, solid,
continuous surface. If the appliance is to be raised
off the floor on a platform, it must be securely
fastened to a sturdily constructed platform.
3) If the appliance is to be installed on carpeting,
combustible vinyl tiling, or any other combustible
surface other than wood flooring, a wood panel or
metal panel must be installed on top of the existing
flooring. The panel must extend the full width and
depth of appliance.
4) The Alpine TR42 fireplace can be installed into
many different applications. See Figure 1 for
examples.
5) Lay out fireplace dimensions on installation site
before proceeding with installation. This will ensure
proper clearances and assist in identifying potential
problems before installation.
6) Make sure to review the vent termination before
proceeding.
