OPERATING MANUAL
SHUTDOWN
HOW TO BURN FIRE DOWN FOR SHUT DOWN
All loading should stop one or two hours before you intend to put the fire out.
As the fire burns down, maintain the air speed until the box begins to smoke. As the
smoke increases reduce the air speed in increments to Positions Normal 1 and the
Cool Down Position. This will help to reduce the smoke.
The air in the manifold needs air flow, both to accelerate the burn down and to protect
the manifold from warping due to excessive heat.
DO NOT shut off the air flow (turn
off the motor) while there are still flames within 24 inches of the manifold.
Doing
so may cause elevated temperatures to warp the manifold, nozzle assembly, etc. Your
warranty does NOT cover damage due to excessive heat.
Once the fire has burned down to about one or two feet and flames are not visible near
the manifold, it will be safe to turn the SPEED SWITCH to the COOL
-
DOWN mode.
After appropriate burn
-
down time, turn the SPEED SWITCH to OFF and push the RED
POWER BUTTON to OFF. Finally, turn the Main FireBox Fan Switch counterclockwise
to the horizontal OFF position.
Make sure the fire is contained as necessary to comply with your local regulations.
Do
not spray the refractory walls with water, as this
will damage them.
Some local authorities allow the FireBox to be secured and the embers to smolder all
night. There is generally no smoke from this smoldering. Insure the work site is se-
cured or has a constant security guard to prevent any people or animals from getting
near the FireBox. The inside temperatures of the FireBox will remain very high most of
the night.
If you are not allowed to smolder through the night, then verify that the fire inside is
completely out. If it is still burning or smoldering you can either water down the embers
or you can use sand or dirt to cover the remaining hot spots. Ensure the fire is out and
the job site secure before you leave.
DANGER:
Falling into the FireBox will cause serious injury or death
.
