NAPOLEON TLV50 Natural Gas to Propane Conversion Kit

Product Information

The product is a gas appliance that requires a fuel conversion kit for models TLV50, TLV62, and TLV74. These kits are designed for use at altitudes of 0 to 4,500 feet. Each kit includes a regulator, burner orifice, propane pilot injector, and conversion data label.

It is important to note that if converting to propane, the appliance must be power vented as stated in the installation manual. Failure to position the parts correctly or use approved parts may result in property damage or personal injury.

Prior to proceeding with the conversion, the gas supply must be shut off and the electrical power disconnected. It is recommended to convert the appliance before final installation and remove porcelain panels for easier conversion.

Product Usage Instructions

Remove the glass guard assembly or safety barrier, door trim, and glass door. Set aside the existing media.
Disengage the air shutter adjustment rod by pushing the smaller end to the left or right (depending on the model). Ensure the rubber grommet stays in place.
Remove the screws securing the entire burner assembly in place. Lift the burner assembly out of the appliance and set it aside.
Using a deep socket wrench, remove the orifice from within the firebox and replace it with the OR/OU orifice supplied.
Remove the two screws from the valve regulator and replace it with the one supplied.
Remove the two screws securing the pilot in place. Using a backup wrench, remove the pilot tube from the bottom side of the pilot. Replace the pilot orifice with the one supplied and reattach the pilot tube and pilot to the bracket.
Fill out the conversion data label and attach it adjacent tothe valve.
Position the burner assembly inside the firebox without securing it. Lift the burner assembly up manually.
Install the media evenly across the burner tray, placing a moderate amount on the burner itself. Adjust if necessary to achieve a pleasing flame appearance.
Turn on the electrical supply to the appliance, followed by turning on the gas supply. Light the pilot to purge the gas lines.
Check for gas leaks by brushing on a soap and water solution.Refer to the lighting instructions in the installation manual. Do not use an open flame. Once all systems have been checked, reinstall the media.
Install the indicator label supplied onto the end of the air shutter adjustment rod.
Reinstall the glass door, trim, and glass guard assembly or safety barrier.

Note: Purge all gas lines with the glass door off and ensure a continuous flow at the burner before replacing the glass door and glass guard assembly or safety barrier.

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 fi re, 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.

Remove the glass guard assembly or safety barrier, door trim and glass door. Remove existing media and set aside.
Disengage the air shutter adjustment rod by pushing the smaller end of the rod to the left or right (depending on model) (Fig. 1). The rubber grommet must stay in place.
Remove the screws that secure the entire burner assembly in place (the number varies by model) (Fig. 2). Lift the entire burner assembly up and out of the appliance. Set aside.
Using a deep socket wrench, remove the orifice from within the fi rebox and replace with the orifice supplied.
Remove the two screws from the valve regulator and remove the regulator, replace with the one supplied (Fig. 2).
Remove the two (2) screws securing the pilot in place. Using a backup wrench, remove the pilot tube from the bottom side of the pilot (Fig 3). Remove the pilot orifice and replace with the one supplied. Re-attach the pilot tube and pilot to the backet.
The conversion data label must be filled out and attached adjacent to the valve.
Position the burner assembly in place inside the fi rebox but do not secure. Lift the burner assembly up then manually engage the larger end of the rod over the left side of the shutter. Ensure the rubber grommet is correctly positioned around the air shutter stud (Fig. 5). Once fully engaged, secure the burner assembly. Ensure the orifice is engaged.
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”.
note: Media should be installed evenly across the burner tray and a moderate amount of Fig. 5 media placed on the burner itself and, if necessary, adjusted to achieve a pleasing flame appearance.
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.
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 media.
Install indicator label (supplied) onto the end of air shutter adjustment rod (Fig. 5).
Reinstall the glass door, trim, and glass guard assembly or 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 glass guard assembly or safety barrier.

ADJUSTMENTS

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

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.

AIR SHUTTER ADJUSTMENT

Appliance| Air Shutter
TLV50| 1/2” (13mm)
TLV62| 1/2” (13mm)
TLV74| 1/2” (13mm)
MAXIMUM INPUT RATINGS

Appliance| Propane
TLV50| 31,500 BTU/hr
TLV62| 38,000 BTU/hr
TLV74| 41,500 BTU/hr

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

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 fl ame lifting from the burner ports. The fl ame may not appear yellow immediately; allow 15 to 30 minutes for the final flame colour to be established. NAPOLEON-TLV50-Natural-Gas-to-Propane-Conversion-Kit-

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 fl ames. Compare them to the illustrations provided. NAPOLEON-TLV50-Natural-
