12. AERATION ADJUSTMENT
(See Fig. 15)
Natural gas appliances have adjustable shutters to control primary
aeration on both rear and front burner tubes.
Propane appliances have an adjustable shutter on the front burner
tube only. The
air holes are at
the right side of
the tubes. The
appliances are
supplied set at
maximum
aeration. For
the majority of
installations no
adjustment will
be necessary.
However, in a
few instances,
performance
may be
improved by
reducing the
aeration by
sliding the
shutters to the
left or right.
Evaluate the
aeration only
after the heater
has warmed up
(approximately
15 minutes).
Decreasing
aeration will cause the flames to appear more yellow or Orange
revealing less glow in the logs. Too little aeration may result in
black carbon forming and dropping into the firebox.
13. COMPLETION OF THE CAST-IRON OUTER CASE
ASSEMBLY
Lifting carefully, place the entire Side Panel/Ashlip assembly onto
the hearth in
front of the
Heater
centralizing the
shallow cut-out
in the cast-iron
ashlip against the
sheet metal
uprights of the
Heater firebox
(Figure 16).
Take the cast-iron
Arched Lintel
component and
observe the fixing
attachments on the
rear, and towards
the inside top of the
Side Panels (Figure
17).
Offer up the arched
lintel component to
the side panels in
turn, and locate
onto the
attachments in the
side panel (Figure
18).
The sheet metal
component attached to
the rear of the arched
lintel should sit on top
of the horizontal front
section of the heater
convection hood.
Ensure the Arched
Lintel is a good fit,
adjusting the location of
the side panels slightly if
necessary.
Take the cast-iron door,
and observe the hinges
on the right hand side,
looking from the front.
Offer up the door to the
ashlip assembly hinge
point and drop the
lower hinge pin into
the hole provided.
Holding the door
using one hand,
carefully lift up the
right hand side of
the arched lintel
component (Figure
19) and offer up the
door to a position
below the top hinge,
which is mounted
on the arched lintel.
Allow the hinge pin
in the arched lintel
to locate into the
door hinge, by carefully lowering the arched lintel into position.
The door should hinge freely. Close the door.
