with air flow through decorative barrier fronts, removal
of decorative barrier fronts or access for service.

overhang into the glass opening.
• Observe all clearances when applying combustible
materials.
• Seal gaps between the finished wall and appliance
top and sides using a 300 ºF minimum sealant.
NOTICE: Surface temperatures around the appliance will
become warm while the appliance is in operation. Ensure
finishing materials used for all surfaces (floor, walls,
mantels, etc.) will withstand temperatures up to 190 °F.
