CHECK YOUR BOXES
Be sure to immediately check your boxes against your shipping list and bill of lading to make sure all boxes are there.
Examine for any damage and notify Almost Heaven Saunas if there needs to be a repair or replacement of damaged or
missing materials.
ELECTRICAL REQUIREMENTS
All electrical wiring must be performed by A QUALIFIED LICENSED ELECTRICIAN. Because of the heat involved in the
sauna, it is required that you use copper wire with 90ºC insulation. Do not use aluminum wire to make the connection.
Consult with an electrician so you can determine the requirements for your particular situation. All wiring must conform
to all national, state and local codes and regulations and according to the instructions provided with the heater.
LOCATING THE SAUNA
Your Grayson Indoor Sauna was specifically designed to utilize your existing floor. As such, assembly is made very sim-
ple since the entire sauna sits on pre-fabricated rails and risers rather than on an integral floor platform. Your sauna can
be assembled on any surface that is firm and flat, including concrete, ceramic, vinyl, laminate or tile. (Installation on a
carpeted surface is not recommended.)
ASSEMBLY
You should use two people for the assembly of the Grayson Sauna. The wall and roof sections are large and need two
people to lift and hold in place during assembly.
Read this entire manual through to the end before proceeding with the assembly.

1. Connect the 4 FLOOR RISERS
Your existing floor will serve as the floor for your
sauna. The pre-fabricated rails and risers will be
placed on your existing floor and provide the
structural support for the sauna room.The 4 floor
risers are pre-drilled and are assembled with 2”
screws. Use a square to be sure the assembled
frame is square.
NOTE: Be sure your surface is flat before you
begin assembly.
Assemble floor riser
2. Position the WALL SUPPORT RAILS
Place the 4 wall support rails with the groove fac-
ing up on top of the assembled floor riser.
Using 2” screws, Draw the corners tight by angle
screwing the corners together.
NOTE: One side of each rail is pre-drilled. After
lining up the rails and prior to screwing them to-
gether, it is suggested that you pre-drill through
the factory-drilled pilot hole into the second rail
using a 1/8” drill bit. Drill about 1” into the sec-
ond rail. This will prevent the possibility of strip-
ping or breaking the screw.
Position wall support rails
3. Fasten WALL SUPPORT RAILS
Using 2” screws, attach the support rails to the
floor riser; be sure that the groove is facing up.
Use 4 screws for each rail.
The combined riser and rails is now called the
wall support section.

Use 2” screws and pre-
drilled holes to attach the
Long Back Rest to Wall
Sections B and C.
24. Drill Hole for LIGHT
CORD

28. HEATER INSTALLATION
Mount the heater as shown in the manufacturer's instructions. The heater should be
mounted on Wall Section E, over the vents and 7” from the floor of the sauna. All the
necessary hardware is supplied with the heater.
Drill a hole below and behind the heater to run the wire and/or conduit according to local
electrical codes. The heater will be hard-wired according to the specific wiring require-
ments for your heater.
Do not attempt to wire the heater yourself. Contact a licensed electrician in accordance
with your local electrical codes. Heater brand may vary depending on where the sauna
was purchased. Install sauna stones in accordance with heater manufacturer instructions.
Typical wiring requirements for distances of up to 30 feet from the breaker box are as follows:
4.5kw-6.0kw heaters require 10-2 w/ground, copper wire only, and 30amp non-GFCI breaker.
8.0kw 8-2 w/ground, copper wire only, and 40amp non-GFCI breaker.
29. Your fence kit will arrive
banded with stretch wrap. It
consists of four pieces, shown
here.
30. Prop up the first pre-assembled portion and attach the two long horizontal pieces.
Make sure the countersunk holes on the wall mounting bracket face inward.
31. Attach the final piece—the
remaining pre-assembled portion.
32. Position the fence around the heater and use the pre-drilled holes to attach it to the
wall.

33. Attach DOOR KNOB
Take the two sections of the door knob and insert
the thread through the hole in the door. Tighten so
that handles are snug to glass.
NOTE: Hand tighten only and be sure rubber gas-
ket is between knob and glass.
Attach Door Knob on Door

OPERATION
After the sauna has been installed, sweep down the inside to remove any sawdust and wood shavings, and then
vacuum completely. Using a damp cloth and warm water, wipe down the entire sauna including the benches to
remove any remaining dirt, dust and debris. Rinse off the sauna stones and install them in or on the heater in
accordance with the heater manufacturer’s instructions. Improper placement of heater stones can result in low-
er than desired heat temperatures. The first time you turn the heater on, set it to the maximum setting and
operate it for about 30 minutes with the door propped open. Then close the door and allow your sauna to come
up to the desired temperature.
Since you most likely will use your sauna as both a "wet sauna" and a "dry sauna", you should install the sauna
stones that have been included with the heater, following the manufacturer’s instructions. These stones are
necessary if water will be sprinkled on the heater to create the "wet sauna", and they will produce more
consistent heating in the dry mode (without the use of water). It is common for a stone to occasionally crack
during initial heating. If excess amounts of water are used during sauna, prop door open to let the humidity es-
cape. Not much water is necessary to achieve a “wet sauna”.
The amount of ventilation in the sauna can be adjusted by means of the vent located toward the top of the sau-
na. It is important to have adequate fresh air flowing through the sauna, and this flow can be adjusted with the
movable vent cover.
TRADITIONAL STEPS IN TAKING A SAUNA BATH
STEP #1 - Set your heater so that the sauna room achieves the desired temperature, usually between 150º F and
170º F. As a novice, you should begin at the lower end of this range and work your way up to the higher
temperatures over several sauna baths.
STEP #2 - Remove all clothing (except maybe your swimsuit), eyeglasses, contact lenses, jewelry, etc. Take a
quick shower with warm water and soap, or a quick dip in your hot tub.
STEP #3 - Enter the sauna initially for about 5 to 15 minutes. Bring a towel into the sauna onto which you can
sit or lay. Leave the sauna room once you have begun to perspire freely.
STEP #4 - Now you may take a cold plunge in your swimming pool, shower or snow bank. After that, relax and
cool down for another 10 to 20 minutes.
STEP #5 - Re-enter the sauna. On this return visit you may wish to sprinkle small amounts of water onto the
stones creating bursts of steam. If the water spills through the heater and onto the floor, you are using too much,
although this will not hurt the heater or the sauna.
STEP #6 - After your final visit to the sauna, relax for at least 20 minutes. Shower with soap and warm water.
Finish your shower with cooler water to close the pores of your skin. Dress only after you have cooled down
completely.
NOTE: Whatever your sauna regimen, it is important that you keep yourself hydrated by drinking plenty
of water!
