Troubleshooting - Napoleon PF600 User Manual

TUBE BURNERS - The burner is made from heavy wall 304 stainless steel, but due to the extreme heat and corrosive environment,
surface corrosion will occur. Use a brass wire brush to remove surface corrosion. Clean any blocked ports using an opened paper
clip. Do not enlarge the burner ports. Spiders and insects are attracted to the smell of propane and natural gas. The burner is
equipped with an insect screen on the air shutter, which will reduce the likelihood of insects building nests inside the burner, but does
not entirely eliminate the problem. The nest or web will cause the burner to burn with a soft yellow or orange flame or cause a fire
(flashback) at the air shutter underneath the control panel. To clean the inside of the burner, it must be removed from the gas grill.
Remove the control panel by removing the two screws in the lower corners of the panel. Disconnect the leads from the igniter
modules. Leave the leads connected to the switches, other than the light switch. Push the control panel upwards to remove. Loosen
the manifold assembly and pull it forward out of the burner. Do not allow the manifold to hang from the aluminum supply tube.
Remove the screw that attaches the burner to the back wall, loosen but don't remove the two screws holding the sear plate mount on
the back wall. Lift out the sear plate mount. Slide the burner back and upwards to remove. Use a flexible venturi tube cleaning brush
to clean out the inside of the burner. Shake any loose debris out of the burner, through the gas inlet. Ensure that none of the burner
ports are blocked. Use an opened paperclip to clean any blocked ports. Ensure that the insect screen is clean, tight, and free of any
lint or other debris. Check also that the valve orifices are clean. Do not enlarge the orifices. Re-install the burner in the reverse
procedure. Check that the valve enters the burner when installing. Replace sear plate mount and tighten screws to complete
installation.
ALUMINUM CASTINGS - Clean castings periodically with warm soapy water. Aluminum will not rust, but due to high temperatures
and weathering, oxidation can occur on aluminum surfaces. This will appear as white spots on the castings. To refinish the castings,
clean them and sand lightly with fine sandpaper. Wipe surface to remove any residue, and paint with high temperature barbecue
paint. Protect surrounding areas from over-spray. Follow curing directions found on the can.
PROTECTION OF INFRA-RED BURNERS - The infra-red burners of your grill are designed to provide a long service life. However,
there are steps you must take to prevent cracking of their ceramic surfaces, which will cause the burners to malfunction. Following are
the common causes of cracks and the steps you must take to avoid them. Damage caused by failure to follow these steps is not
covered by your grill warranty.
1. Impact with Hard Objects - Never allow hard objects to strike the ceramic. Take care when inserting or removing cooking grates
and accessories into or from the grill. If these objects were to fall on the ceramic, it is likely to crack.
2. Water or Other Liquids - Cold liquid contacting a hot surface in substantial amounts can cause the surface to break. Do not throw
water into the grill to douse a flame. Also if the ceramic or interior of a burner becomes wet while not in use, later operation of the
burner can create steam, which may produce enough pressure to crack the ceramic. In addition, repeated soaking of the ceramic will
cause it to swell and expand. This expansion will cause undue pressure on the ceramic and therefore it may crack and crumble.
i) Never throw water into the grill to control flare-ups
ii) Do not attempt to operate the infra-red burners in open air while raining.
iii) If you find standing water in your grill (because of exposure to rainfall, sprinklers etc.), inspect ceramic for
evidence of possible watersoaking. If ceramic appears to be wet, remove the burner from the grill. Turn upside
down to drain the excess water. Bring indoors and allow to dry thoroughly.
3. Impaired Ventilation of Hot Air From the Grill - In order for the burners to function properly, hot air must have a way to escape the
grill. If the hot air is not allowed to escape, the burners may become deprived of oxygen, causing them to back flash. If this occurs
repeatedly, the ceramic may crack. Do not cover more than 75% of the cooking surface with solid metal (ie. griddle or large pan).

TROUBLESHOOTING

Problem
Low heat / Low flame when
valve turned to high.
Possible Causes
For propane - improper lighting
procedure.
For natural gas - undersized
supply line.
For both gases - improper
preheating.
Solution
Ensure lighting procedure is followed carefully. All gas grill
valves must be in the off position when the tank valve is
turned on. Turn tank on slowly to allow pressure to equalize.
See lighting instructions.
Pipe must be sized according to installtion code.
Pre-heat grill with main burners on high for 5 to 10 minutes.
