Cleaning the Media
During shipment of the media, dust and debris can ac-
cumulate. It is recommended that the media be rinsed
thoroughly with water to remove dust and small particles.
An easy method to clean the media is to place the media
into a pail and rinse thoroughly. Spread the media out over
paper towels and allow the media to dry before installing
them into the replace.
Figure 1. Selecting Flat Media for Pilot Cover.

• Do NOT place media in area in front of pilot
• Do NOT place media in a position that they may
fall into area in front of pilot.
• Do NOT use any media other than the media

WARNING! Choking Hazard! Keep media out of reach
of children.
INSTALLATION
Note: If both the media and logs will be installed, the logs
must be installed rst.
1. Choose 7 - 10 round pieces of media approximately
1/2 inch in size and set them aside. These will be used
later to conceal the pilot end of the burner. Reference
Figure 1 for choosing round pieces of glass.
CAUTION! Risk of Burns! The replace should be turned
off and cooled before media is installed.
WARNING! Risk of Explosion! DO NOT put any at
media pieces larger than 1/2 inch in diameter near pilot.
Delayed ignition could occur. Use only round 1/2 inch
pieces near pilot.
NO YES
2. The included media placement jig, shown in Figure 2
(MEZZO/CRAVE) and Figure 3 (PRIMO), MUST be
used any time media are placed on the burner to ensure
that none end up in the burner lighting area. Verify that
the media placement jig is correctly installed in place in
the appliance. See Figure 4.
NOTE: MEDIA-FOG-60 is not approved for use with
PRIMO60/PRIMO60ST Propane appliances. Sooting could
occur.

8. Place the glass frame assembly back on the appliance
according to the instructions provided in the appliance
installation manual. Assure that there is no media be-
tween the glass and the rebox. Media in this area will
prevent the glass gasket from sealing.
Fogging Option
(MEDIA-FOG “Teco-Sil” Only)
7. If desired, the media can be fogged using high tem-
perature black paint (Hearth & Home Technologies
part number TUP-GBK-12). See below for fogging
tips. Prior to painting, take precautions to prevent any
overspray from reaching the pilot assembly.
• Apply paint with the LED lights turned on. This will help
you avoid over fogging or under fogging.
• Ensure rebox interior and logs (if installed) are covered
to prevent overspray.
• Reduce the lighting in the room while applying the paint.
• Fog the media to the desired look.
• Allow the paint to dry/cure a minimum of 15 minutes.
Figure 9. Fogging the Media
MEZZO/CRAVE: Proceed to Step 9.
PRIMO: Proceed to Step 10.
WARNING! Risk of Asphyxiation! Install glass assem-
bly with care. Gasket MUST be sealed. Remove all me-
dia between glass and rebox.
NOTE: MEDIA-FOG-60 is not approved for use with
PRIMO60/PRIMO60ST Propane appliances. Sooting could
occur.

TROUBLESHOOTING
After the initial start up burn, it may be necessary to adjust
the media placement to achieve the best ame appear-
ance. While ame height variation is normal, there may
appear to be higher peaks in some areas and low ame
peaks in other areas.
If the ame height appears to be excessively high in
some spots, applying more media to these areas on top
of the burner will help even out the ames. Spreading
the media as evenly as possible is the most effective way
to achieve optimal ame appearance and the most even
ame heights. One or more test burns may be required
to watch the ames mature and see how even they look
before making adjustments.
Avoid using media pieces larger than two inches in diam-
eter, these can be disruptive to the ame patterns. If you
nd exra large media pieces, discard.
PRIMO ONLY:
10. Place an even layer of media on the transition media
tray as shown in Figure 14.
11. Place the barrier glass in place according to the instruc-
tions provided in the appliance installation manual.
Note: Steps 10 and 11 will be repeated one time if the
