This document is an assembly instruction manual for a "TIGER KERR LOG CABIN," identified by the model number TIG/INS36. It provides comprehensive guidance for the construction, maintenance, and proper use of the log cabin.
Function Description:
The Tiger Kerr Log Cabin is a self-assembly outdoor building designed for various purposes, such as a garden office, storage shed, or recreational space. It is constructed from natural timber logs that interlock to form the walls, with a tongue and groove system for a snug fit. The cabin features double doors and windows, allowing for natural light and access. The assembly process involves building the walls layer by layer, installing the floor, roof, and internal fittings. The design emphasizes durability and longevity, provided proper assembly and annual maintenance are carried out.
Important Technical Specifications:
- Timber: Natural timber logs are used for construction. These logs are subject to natural expansion and contraction due to weather conditions (swelling in rain, warping in dry spells).
- Base Requirements: A firm and level base is essential for proper assembly and to prevent distortion. Recommended base types include durable plastic grids, concrete (75mm laid on 75mm hard-core), slabs (laid on 50mm sharp sand), or a self-constructed/pre-made timber base. The base must be at least the size of the tanalised floor bearers and at least 25mm above surrounding ground level to prevent flooding.
- Fixing Kit Contents:
- Clout Nails (20mm Galvanised): QTY 300 (C20)
- Nails (40mm Galvanised): QTY 30 (N40)
- Screws (40mm): QTY 30 (S40)
- Nails (65mm Galvanised): QTY 300 (N65)
- Screws (60mm): QTY 8 (S60)
- Nails (40mm Bright Annular): QTY 400 (BA40)
- Screws (80mm): QTY 16 (S80)
- M6 Coach Bolts (40mm): QTY 8 (CB40)
- Floor Bearers: Tanalised bearers are positioned approximately 400mm apart. On larger cabins, these may be supplied in more than one piece. Dimensions for bearers are 58mm x 44mm.
- Floorboards: A 2.5mm gap should be left between the edge of the floorboards and the outer logs to allow for expansion and contraction. Floorboards are nailed to tanalised bearers using 2x BA40 per floorboard per bearer.
- Roof Boards: Tongue and groove roof boards are fixed through apex purlins and additional purlins using 2x N65 per board, and through side top logs using 2x N65 per board.
- Roof Battens and Skirting: Roof battens are fixed to the underside of roof boards using 6x N40. Skirting is attached using 6x N40.
- Roof Felt: Felt is applied with a 75mm overhang at each end and overlapping by 75mm between strips. It is secured with CN20 nails at approximately 100mm intervals.
- Fascia Boards (Bargeboards): Attached using 4x N40 per fascia board, nailed through top purlin and bottom roof batten. Finials are secured over the join at the apex using 2x N40. Note: No bargeboards are supplied for the low side of the roof to ensure effective water drainage.
- Storm Braces: Fixed to the inside of gables with 2x CB40. The bottom CB40 should be left slack to allow for cabin expansion and contraction.
- Door and Window Fixing: Fascia boards (internal and external) are screwed into the logs behind with 6x S40 evenly spaced.
- Internal Roof Battens: Fixed to the top side logs using 4x S40 evenly spaced along the batten to seal the roof and side walls.
- Internal Skirting: Secured using 3x S40 evenly spaced along the length, but not fixed to the floorboards.
Usage Features:
- Self-Assembly: The cabin is designed for straightforward assembly by two competent adults, following step-by-step instructions.
- Interlocking Log System: Logs interlock in a staggered pattern, using tongue and groove joints for a secure and snug fit.
- Pre-Drilled Holes: Holes for door framing are pre-drilled in the factory.
- Adjustable Storm Braces: Storm braces are designed to accommodate the natural expansion and contraction of the timber, ensuring structural integrity over time.
- Flexible Installation: The manual offers the option of a "Pro-Installation service" for customers who prefer professional assembly.
- Adaptable Design: The cabin can be customized with internal partitions, requiring full floorboard installation at an earlier stage.
Maintenance Features:
- Annual Treatment: It is ESSENTIAL to treat the building with an appropriate high-quality oil or solvent-based preservative AFTER assembly, both internally and externally, and then annually thereafter. This is crucial for validating the guarantee and ensuring product longevity.
- Weather Mitigation: During extended periods of warm sunshine, it is suggested to spray the outdoor building with water. During heavy or extended periods of rain or snow, it should be sheltered as much as possible to mitigate swelling and warping of the timber.
- Access for Maintenance: The base should be constructed to allow access to all sides of the building for maintenance work and annual treatment.
- Rectifying Gapping: Timber's natural expansion and contraction may cause slight gapping in the log cabin. This can be rectified by unscrewing and re-screwing fascia boards over the course of the year.
- FSC Certified Timber: The product uses FSC-certified timber (FSC® C125286), indicating responsible forestry practices.
- UK Manufactured: The buildings are made in the UK since 1913, implying a long-standing commitment to quality.
