Once the pilot has been lit, and the gas control knob
has been turned to the "ON" position, the main
burners are lit
"ON/OFF/THERMOSTAT" switch to "ON" or to
"THERMOSTAT". If using the optional thermostat,
turn the thermostat to "ON" and set it to a higher
position so that it "calls" for heat (i.e. turns the unit
on). The main burners should light immediately.
Note that the thermostat controls the on/off cycling of
the main burners, but the pilot remains lit regardless
of the thermostat setting. To turn the pilot off, turn
the gas control knob fully clockwise to the "Off"
position.

The gas control valve is equipped with a variable
output control. This control varies the rate of heat
produced by the unit by varying the gas pressure to
the main burner tube. The length of the burn cycle is
affected by a combination of heat output and the
thermostat setting. If your stove turns on and off too
often, try, first, reducing the burn cycle by turning the
HI/LOW knob, on the control valve to a lower
setting. Using the variable output control, the heat
output of the unit can be reduced for mild fall and
spring months, or maximized for the colder winter
months. This adjustment can be made, by the
homeowner, as necessary by turning the variable
output control knob to "HI", "LO", or any setting in
between.
Ht (High Turndown)
The Sterling is equipped with a dual valve system.
This allows for the dramatic turndown that most
other gas systems do not feature. Turn the secondary
valve off, and the rear flames go out leaving the front
flames on for a more relaxed ambience simmer. Turn
the rear flames back on to enjoy the high flames for
more heat. This Ht system is technologically
designed to cover all aspects of heating pleasure.

The air shutter is preset by the manufacturer for
optimum operation and should not need adjustment.
However, it may need adjustment once the unit has
the
been installed to compensate for variations in supply
line pressure, altitude, and other variables. The air
shutter is used to regulate the air-to-gas combustion
mixture, which in turn adjusts the size and color of
the flames.

The air shutter is adjustable while the stove is
burning. The two air shutters on the ember burner
are adjustable. The right one (while facing the front
of the stove) is for the low burn portion of the ember
burner and the left one (while facing the front of the
stove) is for the high burn portion of the ember
burner. The adjusters are located underneath the
front of the unit, and operated by using a 3/8" wrench
