Lennox Hearth ADAGIO-EN - Manual (Page 14)

14 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
To adjust the flame, move the lever arm up or
down (located in the lower control area as shown
in Figure 14). When the arm is positioned all
the way down it is fully open. When the arm is
positioned all the way up, it is closed.
Ensure that the air shutter is closed (push lever
all the way up).
To adjust the flame, move the adjustment rod
(located in the lower control area) up or down
to increase or reduce the air shutter opening,
respectively. Position the air shutter to the factory
setting as shown in Figure 14. Allow the burner
to operate for at least 15 minutes. Observe the
flame continuously.
The adjustment rod, arm and associated
adjustable air shutter is patented technology.
Flame adjustments can be made quickly and
accurately to taste without the need of disas-
sembling the appliance and waiting for 30
minutes after each adjustment.
Propane models may exhibit a flame pattern
that may candle or appear stringy. If this is
problematic or persists as the appliance is
continually operated, adjust the air shutter
closed as described in the previous paragraphs.
Operate the appliance for a period of time as the
effect diminishes, ensuring that the appliance
does not develop sooty flames.
Leave the control knob in “ON” position and
turn the remote switch “OFF.” Close the lower
control compartment panel.
Note: See Figure 13 for proper burner flame
appearance.
CAUTION: DO NOT BEND THE AIR SHUTTER
ROD. MAKE SURE THE AIR SHUTTER MOVES
WHEN THE LEVER ARM IS OPERATED.
The adjustment rod and associated adjustable
air shutter is patented technology. Flame ad-
justments can be made quickly and accurately
to taste without the need of disassembling the
appliance and waiting for 15 minutes after each
adjustment.

project 1" (25 mm) beyond the pilot hood at all
three ports (see Figure 15).
