In good bath everything has to be comfortable: temperature, humidity level, smell. The bath has to get warm quickly, the furnace – to be smokeless, the gentle spicy aroma of brooms should not be muffled by pungent smell of condensate. In many respects these conditions are defined by quality of flue. You should not save time and money on its device, the good flue will pay back for works with excellent draft in any weather, lack of condensate, long service.
It is required to you
- - set of the metalwork tool;
- - scissors on metal;
- - Bulgarian;
- - galvanized leaf 0.8 mm thick;
- - pipe metal Ø146x6 of mm;
- - steel sheet 2 mm thick;
- - basalt mineral wool.
Instruction
1. Design dymokhodadymokhod consists of two parts – top and lower. Both parts represent sandwich-pipes of identical design (two pipes with heat insulator between them). Connection of parts happens in garret space by means of the collar which is put on the place of the connector. Such connector design facilitates installation of flue and replacement of the lower steel pipe in case of its burn-out.
2. Determination of parameters to dymokhodazamerta distance between outlet branch pipe of the furnace and the upper edge of flue. The last has to settle down at distance of 0.5 m from roof ridge if the pipe is located no more than in 1.5 meters from the fad, or flush with the fad at any other provision of pipe. Decide on position of the connector of pipes – approximately in the center of garret space. Designate distance from furnace branch pipe to the place of the connector by letter A (length of the lower part of flue), distance from the connector to pipe top – letter B (length of upper part). Establish lengths of external pipes. The external pipe of the lower part has to begin in 100 mm below ceiling and come to an end to places of the connector. If to designate distance from furnace branch pipe to ceiling by letter B, then length of external pipe of the lower part will be equal to mm A-B+100. Length of external pipe of upper part is equal to B. Opredelites with amount of preparations for external pipes. If to accept thickness of layer of warming of equal 60 mm, diameter of external pipe will be 146 + 120 = 266 mm. Width of leaf of galvanization of which the pipe will be made will be 266*3.14+30 ≈ 865 mm. (30 mm – stock on rolling of pipe).
3. Production to preparation dymokhodaotrezhta for flue parts: • mm pipe Ø146 length And (internal pipe of the lower part); • mm pipe Ø146 length of B (internal pipe of upper part); • leaf of galvanization by mm Bkh865 sizes (for external pipe of upper part); • leaf of galvanization by the sizes (A-B+100) h865 mm (for external pipe of the lower part); • leaf of galvanization by the sizes of 865х200 mm (for the collar connecting parts of flue); • ring from galvanization by mm Ø266x146 sizes – 4 pieces (parts for closing of faces of external pipes); • the sheet of metal 2 mm thick the sizes of 500х500 mm – 2 pieces (for fastening of flue to ceiling and roof; • sheet of metal 2 mm thick the sizes of 40х465 mm (for production of the lock in the place of the connector of pipes).
4. Make components to dymokhodaizgotovta external pipes of Ø of 266 mm. For this purpose bend preparations in the form of pipes and connect edges rolling. Make collar for connection of parts of flue. Cut openings under external pipes of flue (one round, other elliptic) in square preparations of the sheets fixing flues to ceiling overlapping and roof. Drill in their corners openings for fastening to overlapping. Weld on the end of the top internal pipe (around it) strip of metal of 40х465 mm in the form of branch pipe which the top end of the lower pipe will enter (the lock for lining and pipe joint).
5. Cut rectangular openings in ceiling and roof for flue wire the sizes of 450х450 mm.
6. Collect parts to dymokhodavstavta internal pipes in external and fill space between them heater. Close ring-shaped faces of external pipes rings from galvanized leaf, inserting them in external pipes. That they did not drop out, turn in edges of external pipes.
7. Mount to dymokhodustanovita on branch pipe of the furnace and fix the lower part on ceiling overlapping, then establish top. Connect them collar. Internal pipes have to be centered precisely by the lock which is available on the lower end of the top pipe. Provide gap identical from all directions between flue and designs of ceiling and roof then attach square sheets to ceiling and roof. Fill free space between pipe and wood structures of ceiling with asbestos or clay.
8. Make and establish cap on pipe. Arrange on roof waterproofing around pipe.
