Fire Door
Principles of the Fire Door
The Model 600 CSS fire door is water cooled to prevent warping of the
door. It also absorbs heat from the fire and transfers heat to the water,
adding a heat-exchanging surface. Because it is water cooled, the
outer surface will never be hotter than the water in the furnace.
Removal and Replacement
If your fire door needs to be removed or replaced on your Model 600
CSS, please contact your local dealer for assistance.
Opening the Fire Door
It is important to always stand behind the fire door when opening
it. Open the door just slightly to allow air to the firebox. This clears
the firebox of smoke that may be lingering in the firebox. Once the
smoke is evacuated from the firebox it is safe to open the door fully,
always standing behind the door for safety. Refer to the “Safe Furnace
Operation Guidelines” section of the Operators and maintenance manual for further instruction on safe opening
of the fire door.
Refer to Safe Operating Guidelines for further instructions on how to safely open and close the fire
door or contact your local dealer. Ask for a demonstration.
