Requirements for Proper Installation
1. Ensure the steam rooms to be used are vapor proof. They should have a vapor proof door that seals
well so the steam does not escape. Make sure the walls, ceiling and floor materials are suitable for
use with steam and hot condensation, the steam produces.
2. Unit may be installed up to 50 feet away from steam room and 6 feet away from the steam distribution
unit in a dry well ventilated area.
3. Use copper or brass fittings only (NEVER USE GALVANIZED FITTINGS).
4. The water inlet uses 3/8” NPT and steam outlet uses 1/2" NPT for easy installation.
5. The generator must be upright, accessible and on a level surface with all connections on top. Access
panel must be unobstructed and allow for easy access (see Figure 1 & 2).
6. Place a drain/spill pan under the unit. Plumb the connection on it to an approved drain.
7. Connect a tee to the cold water line. Install copper pipe to the tee (see Figure 3).
8. Install a brass shut-off valve on the water inlet line in an accessible area prior to the brass union and
recommended in-line water filter.
9. Before making the last connection to the 3/8” NPT, flush the water line into a five-gallon pail to
remove any silt or other materials that may be in the line.
10. Make the final connection and turn on water. All ThermaSol generators are equipped with an
automatic water fill system. The water will stop after unit is filled.
11. The steam line can run up, down, or horizontal; but cannot run down and then up. If it does, a
steam trap will be produced at the low point blocking the flow of steam. Do not plumb a trap in the
steam line. Insulate the steam outlet piping if the piping run exceeds 10 feet or is exposed to cold
areas. Note: Use steam rated insulation.
12. Do not plumb the pressure relief valve into the steam line. Plumbing the pressure relief valve into
the steam line can be hazardous, should the steam outlet be capped off or obstructed.
13. Pitch/angle steam line back towards generator and avoid perfectly level plumbed lines.
14. Make sure water is turned on before operating the unit.
15. The generator has to be installed below the steam distribution unit.
16. Testing the generator will be done when steam distribution system is connected to the generator.
NOTE: Do not attempt to operate Generator without a Steam Distribution unit connected
to it.
NOTE: The Generator should only be wired to its own separate breaker after the
Generator & Steam Distribution System have been properly located and
installed.
Note: Failure to follow installation instructions specifically will cause the warranty to be void.
