10.	Use a small brush to apply a warm soapy water solution to all gas
	connections (use a half dish soap and half warm water). If a gas leak
	is present, bubbling will occur. Gas leaks can be repaired by using an
	approved pipe thread sealant or approved Teflon tape. NEVER USE AN
	OPEN FLAME WHEN TESTING FOR LEAKS.
11.	Reconnect the electrical power to the unit.
12.	Relight the main burner in both the “HI” and “LO” positions to verify
	proper burner ignition and operation and proper flame appearance
	(refer to Figure 59 or the Front Cover). Also	refer to SECONDARY
	INSTALLATION - LOG SET INSTALLATION for a flame appearance picture.
