Steam Generator & Fluid Heater Installation Manual

NOTE 1: Barometric dampers are recommended on all installations with stack heights over 20 feet (6 meters) and on any low NOx units. NOTE 2: A removable, 4 feet (1.2 meters) minimum, stack section is recommended to facilitate steam generator / fluid heater maintenance and repair. NOTE 3: A backdraft damper must be installed in the exhaust stack for installations in cold weather climates. All backdraft dampers must be air-tight and proof-of-position switches. NOTE 4: Oil-fired units require a 2W x 3H feet (0.6W x 0.9H meter) access portal in the stack for inspection and water washing. A floor drain is required at the bottom of the generator under or close to the burner opening.

Figure 2-2 Standard exhaust stack layout for natural gas and light-oil installations only. Not recommended for heavy-oil machines.
