Fl Ame Characteristics; Restricting Vertical Vents; 10.0 Maintenance - Napoleon Arlington GDS20NSB Installation And Operation Manual

9.4 fl ame characteristics
It's important to periodically perform a visual check of
the pilot and burner flames. Compare them to the
illustration provided. If any flames appear abnormal,
call a service person.

restricting vertical vents

Vertical installations may display a very active fl ame. If this appearance is not desirable, the vent exit must be
restricted using a restrictor vent kit. Refer to the "replacement parts" section of the owner's manual for the
appropriate kit. This will reduce the velocity of the exhaust gases, slowing down the fl ame pattern and creating a
more traditional gentle fl ame appearance. Specifi c instructions are included with the kit.

10.0 maintenance

WARNING
!
• Turn off the gas and electrical power before servicing the appliance.
• Appliance may be hot. Do not service until appliance has cooled.
• Do not use abrasive cleaners on glass.
• Do not paint the pilot assembly.
This appliance and its venting system should be inspected before use and at least annually by a qualifi ed
service person. The following suggested checks should be performed by a qualifi ed technician. The appliance
area must be kept clear and free of combustible materials, gasoline, or other fl ammable vapors and liquids.
The fl ow of combustion and ventilation air must not be obstructed.
note:
Caution: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after servicing.
1. In order to properly clean the burner and pilot assembly, remove the logs, rocks and/or glass to ex-
pose both assemblies.
2. Keep the control compartment, media, burner, air shutter opening and the area surrounding the appli-
ance clean by vacuuming or brushing, at least once a year.
3. Check to see that all burner ports are burning. Clean out any of the ports which may not be burning
or are not burning properly.
4. Check to see that the pilot fl ame is large enough to engulf the fl ame sensor and/or thermocouple /
thermopile as well as it reaches the burner.
5. If your appliance is equipped with a safety barrier, cleaning may be necessary due to excessive lint /
dust from carpeting, pets, etc. simply vacuum using the brush attachment.
6. If your appliance is equipped with relief doors, ensure the system performs effectively. Check that the
gasket is not worn or damaged. Replace if necessary.
7. Replace the cleaned logs, rocks or glass. Failure to properly position the media may cause carboning
which can be distributed in the surrounding living area, inside the fi rebox and on exterior surfaces sur-
rounding vent termination.
8. Check to see that the main burner ignites completely on all ports when turned on. A 5 to 10 second
total light-up period is satisfactory. If ignition takes longer, consult your local authorized dealer / dis-
tributor.
9. Visually inspect the appliance for carbon build up. Using a small whisk or brush, brush off the carbon
and vacuum up or sweep into garbage.
10. This step is not applicable for Vent Free appliances: Check to see that the appliance is vent-
ing correctly. Ensure chimney system is safe and unobstructed. (If for any reason the vent air intake
system is disassembled, re-install and re-seal per the instructions provided for the initial installation).
