2.3 GENERAL
INFORMATION
When the appliance is installed at elevations above 2,000ft, and in the absence of specifi c recommendations
from the local authority having jurisdiction, the certifi ed high altitude input rating shall be reduced at the rate of
4% for each additional 1,000ft.
No external electricity (110 volts or 24 volts) is required for the gas system operation.
Expansion / contraction noises during heating up and cooling down cycles are normal and are to be expected.
This appliance is equipped with a pilot light safety system referred to as an oxygen depletion sensor and is
designed to turn off the appliance if not enough fresh air is available.
4.2C
The grounding prong must not be removed from the cord plug.
As long as the required clearance to combustibles is maintained,
the most desirable and benefi cial location for the appliance is in the
center of a building, thereby allowing the most effi cient use of the
heat created. The location of windows, doors and the traffi c fl ow in
the room where the appliance is to be located should be considered.
If the appliance is installed directly on carpeting, vinyl tile or other
combustible material other than wood fl ooring, the appliance shall be installed on a metal or wood panel
extending the full width and depth.
NOTE: This does not apply to stoves.
* Air shortage caused by an inadequate air supply, improper log positions, the addition of foreign or
unapproved materials or the failure to properly maintain the appliance, may result in incomplete combustion of
the fuel. Incomplete combustion results in soot being deposited inside the fi rebox as well as surfaces outside
the appliance. If any soot deposits are observed, shut off the appliance immediately and arrange for it to be
serviced by a qualifi ed technician.
We suggest that our gas
hearth products be installed
and serviced by professionals
who are certified in the U.S.
