Speed Control Switch; Millivolt System; Burner On/Off - Temco DV5200N Homeowner's Installation And Operating Manual

6. Unpack steel wool and cut off a 1" x 3" (25 x 76mm)
strip. Save the remainder of the steel wool for future
use. Carefully stretch the strip out the full length of
the burner's ported area and then place it on the
ember tray allowing the steel wool to hang over the
burner. Next, place the rock wool loosely on top of
the steel wool and top edge of the ember retainer
along entire length of ported area of front burner.
Use individual pieces of rock wool about the size of
a quarter. Rock wool should be fluffed up and not
compressed. Rock wool must be held up by ember
retainer tray. Do not allow embers to fall on burner
and cover burner ports.
7. Ember tray ends beyond burner port area and area
in front of grate may be covered with lava rock to
suit individual appearance preferences.
8. Purge lines and test pilot operation.
9. Replace glass door. The door must be installed
before operating the fireplace. (Refer to Page 24)
10. Flame should not impinge (touch) on logs.
WARNING: Do not place rock wool, lava rock or any
other materials on the burner. Use only
certified material supplied with this fireplace.
Using uncertified materials will void the
warranty.
