F. To re-install, reverse these steps. Ensure the top and bottom door latches are properly engaged before releasing the door, and check that the door opens freely and closes with a proper seal.

For See-Thru Models (Fixed Side): Under normal conditions, there is no reason to remove the fixed side of the firebox glass door. Servicing can be completed from the access side.

Cleaning Glass Media:

Glass media may have a fine oil residue that needs to be cleaned before installation. Clean the glass with mild dish soap, drain, rinse thoroughly, and let it dry completely before placing it over the burner.

Installing Glass Media:

Evenly spread the cleaned, dry glass media onto the media tray. Ensure that no glass media falls into the pilot opening. Do not place media directly onto the burner or pilot opening, as this will interfere with pilot operation. Do not use more media than what was supplied with the appliance.

Removing Media:

To remove the glass media, use a vacuum cleaner with a clean bag inserted and vacuum out the glass media.

The NAPOLEON L50N is equipped with an externally adjustable air shutter. Adjustments must be made by a qualified installer with the door, burner, and all media installed.

• To open the shutter, pull the adjustment rod away from the appliance.

• To close the shutter, push the rod towards the appliance.

It is recommended to adjust the shutter in 1/8″ increments, as small adjustments can have a drastic effect on the flame appearance. Closing the shutter will cause a more yellow flame but can lead to carbonization. Opening it will cause a more blue flame but can cause flame lifting from the burner ports. Allow 15 to 30 minutes for the flame color to be established after an adjustment.

Pilot Burner Adjustment:

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

Check Pressure Readings:

1. Inlet Pressure: Turn screw (A) counter-clockwise 2 or 3 turns and then place the pressure gauge tubing over the test point. Check the pressure with the main burner operating on “HI”.

2. Outlet Pressure: Check the outlet pressure using screw (B) in the same manner. Check with the main burner operating on “HI”.

3. Reseal: After taking pressure readings, be sure to turn screws clockwise firmly to reseal. Do not overtorque.

4. Leak Test: Perform a leak test with a soap and water solution.

Refer to the pressure chart in the manual for correct readings.

*Maximum inlet pressure not to exceed 13″

Annual maintenance for your NAPOLEON L50N should be performed by a qualified service technician and includes the following checks:

A. To properly clean the burner and pilot assembly, remove the logs, rocks, and/or glass to expose both assemblies.

B. Keep the control compartment, media, burner, air shutter opening, and the area surrounding the logs clean by vacuuming or brushing at least once a year.
