Operating Instructions; Cleaning / Servicing - USSC Ambiance B9945L Installation And Operation Instructions Manual

Wait 30 seconds before readjusting the heater when the control has been turned
down to a lower setting.
MATCH LIGHTING INSTRUCTIONS
If the pilot will not light using the piezo ignitor, you can light the pilot with a match. First, locate the pilot. The pilot
is located between the burner tube on the right end (facing the unit), inside the firebox. To light pilot with a match,
move the gas control (knob B, pg. 13) to the pilot position and hold down. Light match and place near pilot. Once
pilot is lit, continue to hold the knob for about ten seconds. Then follow steps 9 thru 13 on page 13.
CHECKING FLAME APPEARANCE
Flames from the pilot and burner should be visually checked when the heater is installed. In addition, a periodic
check of the flames should be made.
PILOT FLAME
The pilot flame should always be present when the
heater is in operation and should just touch the top of
the thermocouple tip (FIGURE 9).

Annual inspection and cleaning by your dealer or qualified service technician is recommended to prevent
malfunction and/or sooting.
Turn off heater and allow to cool before cleaning.
WARNING
Remove front screen, (see page 11). Carefully lift screen from locating stubs and set aside during cleaning.
Refer to instructions on page 11 for installation of screen. Do not operate the unit with the screen
removed.
Remove logs, handling carefully by holding gently at each end. Gloves are recommended to prevent skin
irritation from ceramic. If the skin becomes irritated, wash gently with soap and water. Refer to manual for
correct log placement.

OPERATING INSTRUCTIONS

If the pilot flame does not touch the thermocouple,
then the main burner is unlikely to function reliably
(FIGURE 10).
