Condensate drain connection to XT Steam Blower
1. Drain line must be routed as shown in the drawing to the left.
Provide a 7" (178 mm) water seal to:
• Ensure drainage of condensate from the steam blower
• Keep steam from blowing out of the drain line
2. After the water seal, run the drain line to an open drain
with a 1" (25 mm) vertical air gap. Cut the drain line at a 45
degree angle on the end above the drain to permit a direct
stream of water into the drain pipe while maintaining a 1"
(25 mm) air gap.
3. All drain lines must be installed and sized according to
governing codes.
4. The XT Steam Blower is constructed with a pitch toward the
drain; however, the XT Steam Blower frame must be installed
plumb and level for proper drainage.
WARNING!
Make sure the XT Steam Blower is installed plumb. If it is not installed
plumb then standing water can accumulate in the steam blower, which
can:
• Cause bacteria and mold growth, which can cause illness.
• Affect unit performance and cause hot water at 212 °F (100 °C)
to discharge from the XT Steam Blower, which can cause severe
personal injury.
