INSTALLATION OF SAUNA ROOM
If the sauna is to be placed against existing wall(s), panel installation
should begin away from the wall starting with the right panel. After these
panels are in place, the sauna can be slid back towards the wall(s) keeping
it 1/2” to 1” separation from wall and sauna.
NOTE: Your sauna can be placed on concrete, tile, linoleum, or any
surface that does not absorb water. Do not install the sauna on
carpeting.
All wall panels are numbered at the top and should be readable from the
interior of the room. These numbers will coincide with the numbers on
the base frame.
NOTE: The tongue and groove on the panels will always face the
same direction
Each panel is heavy. Use caution to avoid injury when
installing, especially the roof panels.
Two adults are required for the installation of sauna room.
Base Installation
1. Position the base frame in the desired location on a level surface.
The largest number on the base frame is the standard door
location. The stamped numbers on the base frame should be
readable from inside of the room.
2. Fasten the corners of the base frame using one 3” screw at each
corner in the predrilled holes. Predrilled holes are purposely made
at an angle. (Image 2)
3. The base rail is numbered to correspond with the panels. (Image 3)
NOTE: Using a level and measuring tape, confirm the base
frame is square by measuring corner to corner. The
dimensions should be the same when the base is square.
Shim where needed to level the base.
Wall Panel Installation
Starting with a back wall corner panel. Slide the panel along the base
frame until framework is flush with the outside of the base frame. Hold
the corner so framework is tight up against the framework of the other
panel.

back to get the tongue and groove alignment started. Then tilt
forward for an easy fit. (Image 4)
4. Secure the back wall to the right wall with three 3” Torq screws
(screws and bit provided). Install one screw on the top of the wall,
one in the middle, and one on the bottom. Ensure the tongue and
groove wall boards are tight together at the interior corner of the
sauna and the corner is flush on the outside edge when screws are
installed. (Image 5)
5. Secure the two wall panels together with a 3” screw (screw
provided) where the panels meet on top. Ensure tongue and
groove are fully engaged. (Image 6)
6. Continue setting the panels into place matching base number with
panel number as marked.
NOTE: A rubber mallet or wood block and standard hammer can
be used to make sure that the bottoms of each panel are even
with the corners of the base frame/floor perimeter. Be careful not
to damage the panels when using this technique.
Top Plate Installation
7. After installing the wall panels, install the 1” thick top plate. This
top plate aligns and locks the top of the wall panels together.

COMMONLY ASKED QUESTIONS
CLEANING
Yes, cleaning is needed. Perspiration and dirt may absorb into the
wood, so periodic cleaning is needed. Scrubbing the benches and
floorboards with a stiff brush and mild detergent is normally
sufficient. Light sanding with 220 grit is another option.
INTERIOR PAINT OR STAIN
You should never apply any paint or stain to the interior of your sauna! Off-gassing from these products
could be harmful to your health when the room is heated.
The only approved product to use on the interior of your sauna is 100% Pure Paraffin Oil. Pure Paraffin Oil
is odorless and will add an invisible layer of protection from moisture stains and can be applied to walls or
bench tops. Paraffin oil can also be used on the exterior surfaces but will darken softer woods like cedar.
See your sauna retail dealer for details.
PATCHING NAIL HOLES
Small nail holes from attaching your trim can be easily filled by using a quality brand of wood filler that
matches the wood you are using followed by a light sanding with 220 grit sandpaper. Small holes or cracks
can also be patched by filling with white glue then sanding with 220 grit sandpaper before the glue dries.
The sanding dust will stick to the glue and fill the void, providing a nearly invisible patch.
TROUBLESHOOTING
Error Codes on SL2 Control
Sn = Means the sensor is not connected to the CB box. Check the connections between sensor and box
HL = Means the High Limit switch in sauna heater is not connected to the CB box. Check the connections
between heater and box.
JP = Means a jumper CN 6 is missing from the Main PCA in CB box.
Pre-Heat = Means there is no sensor connected to the CB or the temperature is below 8°F.
