Requirements For Proper Installation
1. Ensure the steam room to be used is vapor proof. It 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 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 and powerflush valve must be unobstructed and allow for easy access (see Figure 1).
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.
Note: Failure to follow installation instructions specifically will cause the warranty to be void.
Sizing Your Steam Room
Factory Sized:
L x W x H = Cubic Feet
Then choose the appropriate Model. No complicated
formulas. It’s that simple. For every foot of ceiling
height over 8 ft. (always round up) use the next larger
steam unit. Wall material irrelevant.
