Pre-Lighting Checklist

Be sure to check these items before the initial lighting of the
insert:
- All packaging materials are removed from the firebox; brick
panels and logs are installed.
- The insert gas label must correspond to the gas supply available,
that is "natural gas" for natural gas; "LP gas" for LP gas.
- Be sure the gas pressure has been carefully checked (see Gas
Pressure Requirements).
- Fingerprints or other marks are cleaned (while the insert is cool)
from any gold or nickel surfaces with denatured alcohol and
a soft cloth. Marks left on these surfaces may become etched
into the finish if not removed prior to burning the unit.
- Check all gas fittings for leaks.
- Remove all combustible materials from the area in front of
the insert and ensure the vented areas of the insert face are
unobstructed.
- Check to ensure all clearances to combustibles are met-see
Page 8.
- Make sure the glass door is in place and properly sealed before
burning the appliance
- Ventilate the house to clear initial paint curing odors, see Page
