H gh Alt tude Installat ons
U.L. Listed gas fireplaces are tested and approved for elevations from 0 to
2,000 feet in the U. S. A. and from 0 to 4,500 feet in Canada.
When installing this fireplace at an elevation above 2,000 feet (in the United
States), it may be necessary to decrease the input rating by changing the
existing burner orifice to a smaller size. Input should be reduced four percent
(4%) for each 1,000 feet above sea level, unless the heating value of the gas
has been reduced, in which case this general rule will not apply. To identify the
proper orifice size, check with the local gas utility.
When installing this fireplace at an elevation between 2,000 and 4,500 feet (in
Canada), the input rating must be reduced by ten percent (10%).
When installing this fireplace at an elevation above 4,500 feet (in Canada),
check with local authorities.
Consult your local gas utility for assistance in determining the proper orifice for
your location.

when using the REAR vent collars.
The flame and ember appearance may vary based on the type
of fuel burned and the venting configuration used.
WARNING: YOU MUST NOT MIX D-SERIES AND
SL D-SERIES COMPONENTS IN ANY VENT
SYSTEM CONFIGURATION.
Ident fy ng Vent Components
Approved vent system components are labeled for identification.
NO OTHER VENTING SYSTEMS OR COMPONENTS MAY
BE USED. This pipe is tested and listed as an approved
component of the fireplace. There is no requirement for
inspection openings at each joint within the wall. The pipe is
tested to be run inside an enclosed wall. There is no required
pitch for horizontal vent runs. Detailed installation instructions
are included with each vent termination kit and should be used
in conjunction with this Installers Guide. Figure 6 shows vent
system components and terminations.
The vent systems installed on this gas fireplace may include
one, two, or three 0° elbow assemblies. The relationships of
vertical rise to horizontal run in vent configurations using 0°
elbows MUST BE strictly
adhered to. The rise to run
relationships are shown in the venting drawings and tables on
the next several pages.
NOTE: Two 45° elbows may be used in place of one 0° elbow.
You MUST always maintain the MAXIMUM and MINIMUM rise-
to-run ratios in the vent system when using 45° elbows.
