This conversion kit shall be installed by a qualiﬁed service agency in accordance with the manufacturer’s instructions and all applicable codes and requirements of the authority having jurisdiction. If the information in these instructions is not followed exactly, a ﬁre, explosion or production of carbon monoxide may result causing property damage, personal injury or loss of life. The qualiﬁed service agency is responsible for the proper installation of this kit. The installation is not proper and complete until the operation of the converted appliance is checked as speciﬁed in the owner instructions supplied with the kit.

WARNING: Failure to position the parts in accordance with these diagrams or failure to use only parts speciﬁcally approved with this appliance may result in property damage or personal injury.

CAUTION: Before proceeding with conversion the gas supply must be shut off prior to disconnecting the electrical power.

important:

We strongly recommend converting your appliance prior to ﬁnal installation and removing porcelain panels for conversion.

1. Remove the safety barrier, door trim and glass door. Remove existing media and media trays. Set aside.

2. Disengage the air shutter adjustment rod by pushing the smaller end of the rod to the left then push towards the back of

the appliance until the rod clears the rubber grommet (Fig. 1). The rubber grommet must stay in place.

3. Remove the screws that secure the entire burner assembly in place (screw counts vary by appliance size) (Fig. 2). Lift the

entire burner assembly up and out of the appliance. Remove the air shutter adjustment rod. Set both aside.

4. Using a deep socket wrench, remove the oriﬁce from within the ﬁrebox and replace with the oriﬁce supplied.

5. Remove the two screws from the valve regulator and remove the regulator, replace with the one supplied (Fig. 2).

6. Remove the pilot spring clip then the pilot hood from the pilot assembly by pulling vertically. Use a 5/32” Allen key to

unscrew the injector. Replace the pilot injector with the one supplied (Fig. 3). Re-assemble the pilot hood onto the assembly and reattach the spring clip ensuring key position for proper alignment.

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.

ADJUSTMENTS

NOTE: Your appliance may be equipped with either a rotating or a sliding air shutter cap.

VENTURI ADJUSTMENT

EXTERNALLY ADJUSTABLE AIR SHUTTER

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.

WARNING: AIR SHUTTER ADJUSTMENT MUST BE DONE BY A QUALIFIED INSTALLER.

PILOT SCREW

Closing the air shutter will cause a more yellow ﬂame, but can lead to carboning. Opening the air shutter will cause a more blue ﬂame, but can cause ﬂame lifting from the burner ports. The ﬂame may not appear yellow immediately; allow 15 to 30 minutes for the ﬁnal ﬂame colour to be established.

AIR SHUTTER ADJUSTMENT

PRESSURE ADJUSTMENT

Adjust the pilot screw to provide properly sized ﬂame. Turn in a clockwise direction to reduce the gas ﬂow.

Inlet pressure can be checked by turning screw (A) counter-clockwise until loosened and then placing pressure gauge tubing over the test point. Gauge should read 7” (minimum 4.5”) water column for natural gas or 13” (11” minimum) water column for propane. Check that main burner is operating on “HI”.

Outlet pressure can be checked the same as above using screw (B). Gauge should read 3.5” water column for natural gas or 10” water column for propane. Check that main burner is operating on “HI”.

AFTER TAKING PRESSURE READINGS, TIGHTEN SCREWS FIRMLY TO SEAL. DO NOT OVER TORQUE. LEAK TEST

FLAME CHARACTERISTICS

It’s important to periodically perform a visual check of the pilot and burner ﬂames. Compare them to the illustrations provided.
