This document provides instructions for assembling the "Sauna Frodo 4x 1,95," a barrel-shaped outdoor sauna. The manual emphasizes reading all instructions before starting assembly and notes that all measurements are in millimeters.
Function Description
The "Sauna Frodo 4x 1,95" is a pre-fabricated, barrel-shaped outdoor sauna designed for personal use. It features a main sauna room, a changing room (saunaroom), and a front door with three circular windows. The design incorporates a rounded roof structure, which is covered with underlay felt and roof shingles for weather protection. The interior includes benches for seating and a designated area for a sauna heater, along with ventilation openings.
Important Technical Specifications
The sauna's dimensions are indicated by "4x 1,95," likely referring to its length and diameter in meters, though specific overall dimensions are not explicitly stated as a single value. However, various components provide insight into the structure's size:
- Foundation Beams: The base structure involves beams with lengths such as L=4100 mm (A1) and L=7000 mm (A2), and cross-sections like 3264x100x47 mm (SM), 1950x(variable)x42 mm (STL), and 1746x100x28 mm (PL). The foundation layout shows a 3120 mm back side and 1700 mm depth, with support blocks spaced at 1560 mm and 850 mm intervals.
- Wall Boards: The barrel walls are constructed from numerous wooden boards, with various lengths and cross-sections, such as 1950x50x50 mm (7, 7a, 21) and 1746x112x28 mm (PL).
- Door: The main door (10, 10a, 10b, 11, 11a, 11b, 11c) has a frame with dimensions like X4318 mm and 1509243 mm. The door opening is measured and adjusted by adding 10 mm to each side, with an approximate width of 560 mm. The door itself has three circular windows.
- Window: A circular window (12a, 12b) has a radius of 499 mm and is positioned within a 1550 mm high section, with its center 740 mm from the base.
- Benches: Interior benches (15a, 15b, 15, 2xDET 15) are constructed from boards like 540x44x44 mm and 150x44x44 mm. The bench supports (4xDET 15a) are 1110x590x18 mm. The benches are installed at heights of approximately 290 mm and 652 mm from the floor, with a 320 mm vertical separation.
- Roofing: The roof structure is covered with underlay felt (11 m roll) and shingles (DET N, DET O). The underlay felt should extend approximately 50 mm over the edge.
- Ventilation: Three Ø110 mm holes are to be made for ventilation, positioned approximately 850 mm from the center on either side. Upper and lower vents are installed (2xDET F, 4xDET G).
- Heater Area: The sauna heater area (5xDET 20, 1xDET 20a, 1xDET 20b) is defined by minerit boards (595x595x10 mm, 595x95x28 mm, 1250x595x10 mm, 1200x43x18 mm) and positioned 15 mm from the wall.
- Fasteners: Various screws are used for assembly:
- H: 4.5x60 mm (e.g., 6x H, 4x H, 75x H, 5x H, 8x H, 30x H)
- I: 4.0x50 mm (e.g., 18x I, 10x I, 6x I, 8x I)
- J: 3x40 mm (e.g., 38x J, 18x J, 2x J, 10x J, 30x J, 5x J)
- K: 3x30 mm (e.g., 12x K, 6x K)
- M: 4.5x90 mm (e.g., 6x M, 9x M, 4x M, 10x M)
- L: L=250 mm (e.g., 2xDET L)
- Additionally, ~1kg of unspecified fasteners are included.
- Wood Type: The manual differentiates between "Regular wood" and "Thermo wood" for screw depth (X= 7-8 mm for regular, X= 3-4 mm for thermo), indicating that the sauna can be made from either material. It also specifies not to remove screws if the sauna is made from thermowood.
Usage Features
- Sauna Functionality: The primary usage is as a sauna, with designated areas for a heater and benches.
- Changing Room: The "Saunaroom" (changing room) is integrated into the design, providing a space separate from the main sauna area.
- Ventilation: Upper and lower vents, along with three Ø110 mm holes, ensure proper air circulation within the sauna.
- Door and Window: The front door provides access, and the circular windows allow for natural light.
Maintenance Features
- Underlay Felt and Shingles: The roof is designed with underlay felt and shingles for weather protection. The manual emphasizes checking the installation manuals for these components, suggesting they are crucial for long-term durability and may require specific installation techniques or periodic checks.
- Threaded Rods: During assembly and retightening of the threaded rods (DET E1, DET D, DET C, DET E2), the use of oil (e.g., Würth HPS 1400) is recommended to prevent "cold welding" and facilitate tightening, implying these rods are critical structural elements that may require occasional retightening.
- Wood Glue: The use of wood glue between boards is specified, indicating a need for strong, durable joints that contribute to the sauna's structural integrity and weather resistance.
- Drill Holes: Pre-drilling holes (Ø4mm for screws, Ø3mm for window frame) is specified to prevent wood splitting and ensure proper fastener installation, which is a key aspect of maintaining the structure's integrity.
- Material-Specific Instructions: The distinction between "Regular wood" and "Thermo wood" for screw removal highlights material-specific maintenance considerations, where thermowood may have different properties affecting fastener interaction.
