DELTA2 Owner's Manual 6 RSF Woodburning Fireplaces
OPERATION
AIR CONTROL
The combustion air control handle is located below the right
window frame (see Figure 2). When the handle is to the far
right, the control is fully open and the fire will burn more quickly.
When the handle is to the far left, it is fully closed and the fire
will burn more slowly.
Independent of the air control handle position, right (open) or
left (closed), the bimetallic coil integrated in the draft control will
cycle through keeping the air control open in the position you
have selected until the bimetallic coil becomes warm enough to
close the draft control to prevent overheating. It will then cool
down until it is cool enough so that the bimetallic coil will open
the draft control back to the position you have selected until it is
warm enough to close the draft control again.
LIGHTING
Before starting a fire, make sure to completely open the draft control. It is located below right window frame and
should be pushed completely to the right. Light a fire in the fireplace, starting with paper and kindling only. Then
add three or four pieces of wood, about 3" diameter. After the fire is established, close the door. Never use any
flammable liquids. Once a coal bed is established, add standard cord wood. Leave the draft control open until the
fire is well lit, then adjust it to the level you desire.
WARNING: DO NOT USE A GRATE OR ELEVATE THE FIRE.
