Notes:
1. Pitch hard piping or flexible hose 2" per foot if steam is flowing uphill, 1/4" per foot if the steam is flowing
downhill. Reference piping examples shown.
2. When feasible to do so, install a minimum one-foot riser from the top of the tank to reduce condensate carryover.
3. Use flex connectors or unions to allow for easy removal of cover.
4. Support flexible hose every 18" to avoid sagging.
5. Hard piping or flexible hose must match reservoir outlet size. Do not use supply piping with a smaller inside diameter
than the reservoir outlet.
6. Failure to follow the piping recommendation on this page may result in blown water seals, leaking cover gasket, or
dispersion tubes spitting.
7. Install a Drain Tee at any low spots in supply piping run where condensate will accumulate.
All
horizontal to vertical
up transitions require a water-sealed drip leg.
8. Reference job specific tube assembly O&M included with your order for complete details.
