6. Replace standard burner with log burner that is includ-
ed with log kit. Secure the burner bracket to the valve
plate with one screw. Reinstall pilot assembly with two
screws. Ensure all excess pilot wires are pushed back
down through grommet. Reinstall the pilot hood with two
screws. Place base pan in appliance. Reinstall the two
screws in front of the burner.
7. Bend tab “up” from basepan to 90 degrees:
COSMO42-IFT: Bend 9 tabs and bend air tab. See Fig-
ure 3.
SLR-X-AU: Bend 7 tabs. Do not bend the two right rear
tabs or the air tab. See Figure 3.

INSTALLATION
1. Remove fixed glass assembly by unlatching the top left
and right spring latches. Allow the fixed glass assembly
to tilt away from the fireplace and lift the fixed glass as-
sembly up and out of the opening.
2. Remove any existing media from appliance.
3. Remove the base pan assembly by removing two
screws located in front of the burner. Use your thumbs
and fingertips to grasp the front of the base pan and the
flange in the front of the burner respectively. Lift base
pan up and out.
4. Begin removal of the burner assembly by removing two
screws that secure the pilot hood to the bracket that is
attached to the burner. These screws are located on the
back side of the pilot hood. Once the screws are re-
moved, slide the pilot hood toward the back wall of the
firebox and lift out.
Remove the two screws that attach the pilot assembly
to the burner bracket. Remove the screw that fastens
the burner bracket to the valve plate. Remove burner
by sliding it to the left to disengage the orifice flex. See
Figure 1. Discard original burner and media material.
5. Adjust air shutter setting on new burner. See Table 1.
Note: The burner shutter gap is pre-set at the factory to
the "fully open" position and is to be field adjusted at the
time of installation. Shutter settings referenced below are
set based on the minimum vent configuration (one elbow
application). See appliance Installation Manual.

11. COSMO42-IFT Only:
Install Log #3 by positioning front tip of log against
front lip of basepan with right side of log contacting
log tab. Swing rear tip of log back until it contacts
back wall of firebox. Log #3 will rest on Log #1. See
Figure 6.
SLR-X-AU Only:
Install Log #3 by resting it on top of Log#1. Log #3
will cross the burner and rest on the front lip of the
basepan. Right side of log will contact log tab. See
Figure 6.
Note: When Log #3 is correctly positioned on Log
#1, the left side of both logs will line up vertically. See

10. Install mineral wool on burner. Mineral wool can be
placed the entire length of the burner, but it must only
be placed between the front row of ports and the space
in front of the burner. The mineral wool should not
cover any ports or fall so that it covers the gap behind
of the burner. See Figure 5.
