Ember material is shipped with this gas appliance. To place
the ember material:
• Embers CANNOT be placed directly over ports. Care
should be taken not to cover the lighting trail of ports
(from back to front).
• Place dime-size pieces of Glowing Embers® just in front
of the port trail, but not on or in between the ports. See
Figure 11.3. Care should be taken so that the ports are
not covered. Failure to follow this procedure will likely
cause lighting and sooting problems.
