	condensation will disappear.
Blue flames	This is a result of normal operation and the flames will begin to yellow as the appliance is allowed
	to burn for 20 to 40 minutes.
Odor from appliance	When first operated, this appliance may release an odor for the first several hours. This is caused
	by the curing of materials from manufacturing. Odor may also be released from finishing materials
	and adhesives used near the appliance. These circumstances may require additional curing
	related to the installation environment.

	3 to 4 hours of initial burning. A non-abrasive cleaner such as gas appliance glass cleaner may be
	necessary. See your dealer.
