ADJUSTMENTS
VENTURI ADJUSTMENT
NOTE: Your appliance may be equipped with either a rotating or a sliding air shutter cap.
This appliance is equipped with an externally adjustable air shutter that is not preset from factory. Any adjustment will be required
after any change to the appliance. Any adjustments made to the shutter must be done with the burner and all media installed into
the unit. It is important to operate the unit and verify that the air shutter is opened to the correct amount to prevent either flame
lifting or carbonization. To open and close the shutter, pull the knob away from the unit and push the knob towards the appliance
respectively.
Small adjustments on the shutter can have a drastic effect on the flame appearance; it is recommended to adjust the shutter in
1/8” increments.

7. Install the new air shutter adjustment rod (supplied) by sliding the smaller end through the rubber grommet from the inside
of the firebox. The rubber grommet must be seated correctly in order to properly seal the appliance.
8. Remove screws securing the old burner tube to the burner assembly (screw count varies by size of appliance) (Fig. 4).
9. Slide the new burner tube into place within the burner tray assembly and secure using the screws previously removed.
10. The conversion data label must be filled out and attached adjacent to the valve.
11. Position the burner assembly in place inside the firebox but do not secure. Lift the burner assembly up then manually
engage the larger end of the rod over the left side of the new air shutter. Ensure the rubber grommet is correctly
positioned around the air shutter stud (Fig. 5). Once fully engaged, secure the burner assembly.
12. Reinstall media trays, unless using sand as media. It is recommended not to reinstall the media trays for propane
applications with other media types. Not only will this provide a clean look to the appliance, but it also results in a more
pleasing and clean burning flame. Media trays should be stored in the event it is planned to install alternate media at
some point in the future. Media should be installed evenly across the burner tray and a moderate amount of media placed
on the burner itself and, if necessary, adjusted to achieve a pleasing flame appearance. Never place excessive media
on the burner as this can result in carboning or an unappealing flame characteristic. Never place media in the
pilot housing or over the pilot. Always check that the appliance ignites smoothly across the entire burner to ensure
media does not compromise performance. Pay particular attention when using power vents to ensure media placement
does not affect ignition or flame characteristics. Adjust the air shutter according to the table under “venturi adjustment”.
13. Turn on the electrical supply to the appliance. Turn on the gas supply. Then light the pilot to ensure the gas lines have been
purged.
14. Check for gas leaks by brushing on a soap and water solution. Refer to the lighting instructions in your installation
manual. Do not use open flame. Once all systems have been checked, reinstall old media.
15. Install indicator label (supplied) onto the end of air shutter adjustment rod (Fig. 5).
16. Reinstall the glass door, trim, and safety barrier.
Purge all gas lines with the glass door off.
Assure that a continuous flow is at the burner before replacing the glass door and safety barrier.
