The NAPOLEON L50N2 has an option to change from an electronic intermittent pilot ignition (IPI) to a standing pilot for cold climates using the anti-condensation control (ACS) switch. This is located to the left of the control panel.

• To use a standing pilot, flip the switch up.

• To use an intermittent pilot, flip the switch down.

Turning the ACS switch on allows the pilot flame to burn continuously. This mode minimizes condensation on the inside of the glass when the main burner is first turned on and helps the appliance and vent system stabilize more quickly in colder months. During warmer months, the ACS switch can be turned off to minimize fuel consumption.

FRONT – ACCESS SIDE:

A. Remove the safety screen assembly.

B. Remove the door trim by carefully lifting it up and off the frame of the glass door.

D. For door removal, locate the top and bottom door latches. Pull latches forwards and away to disengage them. Ensure to leave one hand on the glass door during the entire removal process.

E. Tilt the top of the door forwards 90 degrees, then lift it up and out of the door latches.

F. To re-install, reverse these steps. Ensure the top and bottom door latches are properly engaged prior to releasing the door. Make sure the door opens freely and closes sealed.

FIXED SIDE – SEE-THRU ONLY:

G. Remove the screws securing the door to the appliance.

H. Tilt the top of the door forward, then lift it up and out of the bottom door retainer.

I. When re-installing the door, lift it onto the bottom door retainer, tilt the top towards the appliance and secure with the previously removed screws.

Note: 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 prior to installation. Clean the glass with mild dish soap, drain, rinse thoroughly and dry before placing over the burner.

Installation:

Evenly spread the cleaned, dry glass media onto the media tray. Ensure no glass media falls into the pilot opening. If this happens, insert a clean bag into your vacuum cleaner and vacuum out the glass media. Do not use more media than what was supplied with the appliance, and do not place media directly onto the burner or pilot opening.

Removing Media:

Using a vacuum cleaner, use a clean bag and vacuum out the glass media.

The air shutter on your NAPOLEON L50N2 is externally adjustable. Adjustments must be done 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.

Small adjustments (1/8″ increments) can have a drastic effect. Closing the shutter causes a more yellow flame but can lead to carbonization. Opening it causes a more blue flame but can cause flame lifting. Allow 15 to 30 minutes for the flame color to be established after an adjustment.

Pilot Adjustment:

Adjust the pilot screw to provide a properly sized flame. Turn the screw clockwise to reduce the gas flow. The flame must envelop the upper 3/8″ to 1/2″ of the flame sensor.

Check Pressure Readings:

Pressure checks should be performed by a qualified technician.

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

• Outlet Pressure: Use screw (B) in the same manner as above. Check pressure with the main burner on “HI”.

After taking readings, turn screws clockwise firmly to reseal. Do not overtorque. Leak test with a soap and water solution.

*Maximum inlet pressure not to exceed 13″

This appliance and its venting system should be inspected at least annually by a qualified service person. The following checks should be performed:

A. To properly clean the burner and pilot assembly, remove the media (glass, etc.) to expose both assemblies.

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

C. Check that all burner ports are burning and clean any that are not.

D. Check that the pilot flame is large enough to engulf the flame sensor.

E. Replace the cleaned media. Improper positioning can cause carbon buildup.

F. Check that the main burner ignites completely within 5 to 10 seconds.

G. Check the door gaskets for damage and replace if necessary.

H. If the vent air intake system was disassembled, ensure it is re-installed and re-sealed correctly.

I. Clean the safety barrier with a vacuum brush attachment to remove lint/dust.

J. Ensure the relief system performs effectively. Check that the gasket is not worn or damaged.

Do not clean the glass when it is hot and do not use abrasive cleaners. Glass cleaners with ammonia will discolor the glass.

1. Buff lightly with a clean, dry, soft cloth to remove dust or fingerprints.

2. Clean both sides of the glass after the first 4 hours of operation with a recommended fireplace glass cleaner.

3. Thereafter, clean as required. If the glass is not kept clean, permanent discoloration may result.

If the glass should ever crack or break while the fire is burning, do not open the door until the fire is out. Do not operate the appliance until the glass has been replaced. Use only factory-supplied 4mm tempered glass. DO NOT SUBSTITUTE MATERIALS.

To remove the burner assembly:

A. Remove the safety screen and glass door.

B. Remove the media from the appliance.

C. Remove the pilot housing by removing the screws.

D. Remove the screws that secure the media tray in place. Lift the burner assembly up and out of the appliance.

If there is noise but no spark, the issue could be with the wiring, a lack of signal from the remote, poor grounding, or improper switch wiring. Check the following:

• Verify the thermocouple/sensor is clean and the wiring is undamaged. Ensure connections from the pilot assembly are tight and not grounding out to any metal.

• If there is no signal from the remote, try reprogramming the receiver code or replace the receiver.

• Verify the valve and pilot assembly are properly grounded.

• Troubleshoot the system with the simplest on/off switch.

If the pilot sparks but doesn’t light, check these potential causes:

• Dirty Pilot/Sensor: Clean the sensor rod with a green Scotch-Brite™ pad to remove any contamination.

• Gas Supply: Verify the incoming gas line ball valve is “open” and that inlet pressure is within acceptable limits (not to exceed 14″ W.C.).

• Out of Propane: If applicable, fill the tank.

• Air in Line: Repeat the ignition process several times or have a technician purge the pilot supply line.

• Incorrect Wiring/Grounding: Ensure correct polarity of thermocouple wiring and verify the pilot assembly/valve are properly grounded.

• Receiver Issue (if equipped): Try resetting the program. Hold the reset button on the receiver for 2 beeps, release, then press the small flame button on the remote within 20 seconds. If this fails, replace the receiver.

• Valve: The valve may need to be checked and replaced if necessary.

This issue is often caused by a poor connection or a dirty pilot assembly.

• Connection Issue: Verify all connections in the sensor rod circuit. Ensure connections from the pilot assembly are tight and not grounding out to any metal.

• Dirty Components: Clean the sensor rod, pilot hood, ignitor, or flame sensor with a green Scotch-Brite™ pad to remove any contamination.

This could be caused by incorrect installation or a wiring issue:

• Wall switch mounted upside down: Reverse the switch.

• Remote wall switch and/or wire is grounding: Replace the switch. Check for a ground (short); repair the ground or replace the wire.

• Faulty wire: Replace the wire.

Here are common solutions for remote control issues:

• Remote is locked out (controls lights but no spark): Reset by turning the power source off then on. If back-up batteries are installed, they must also be removed to reprogram.

• Low Battery: Replace batteries in the receiver or remote.

• Synchronization Error: Reset the receiver and remote.

• Out of Range: Move closer to the receiver.

• Bent Connector Pins: Straighten the pins.

• Damaged Valve Wiring: Replace the valve.

If the flames appear very aggressive, the cause could be one of the following:

• Door is ajar: Ensure the door is secured properly.

• Venting action is too great: Check to ensure the venting is properly sealed. For some appliances, a restrictor plate can be used to restrict the vent exit.

Carbon deposition can result from several issues related to air supply and flame impingement:

• Air shutter improperly adjusted: Return the air shutter to the specified opening as described in the “venturi adjustments” section of the installation manual.

• Air shutter is blocked: Ensure the air shutter opening is free of lint or other obstructions.

• Flame is impinging on the media: Ensure the media is positioned correctly in the appliance and open the air shutter to increase primary air.

• Incorrect input rate: Check the manifold pressure and orifice size to ensure they match the specifications on the rating plate.

• Poor seal: Ensure door gaskets are not broken or missing and the seal is tight. Also, ensure vent liners are free of holes and well-sealed at all joints.

A white or grey film is typically caused by sulphur from the fuel being deposited on the combustion chamber surfaces. This should be cleaned using a recommended gas fireplace glass cleaner. Do not clean the glass when it is hot. If deposits are not cleaned off regularly, the glass may become permanently marked.
