Kitchen equipment construction process

>>> Links: 5 taboos for kitchen decoration

Kitchen Equipment Installation <br> Process Flow:
Wall and ground floor treatment → Install product inspection → Install the cabinet → Install the base cabinet → Connect commissioning and drain → Install the matching electrical appliances → Test and adjustment → Clean up.

Construction essentials:
1. Inspection of kitchen equipment before installation.
2. The installation of wall cabinets should be based on different wall fixing methods.
3. The leveling knob should be adjusted before installing the cabinet to ensure that the countertops and front faces of the cabinets are all on a horizontal plane. Use wooden screws to connect the two cabinets. Pipes, tables, and valves on the back panel should be punched in the backplane. .
4. Install a plastic circular pad at the bottom of the water hole in the bottom plate of the washing cabinet. The connection point of the down water pipe should ensure that there is no water leakage and no water seepage. Do not use any type of adhesive to connect the interface part.
5. When installing the stainless steel sink, ensure that the sink and the countertop are connected evenly without leakage.
6. Install the faucet and require a firm installation. The water connection cannot seep.
7. The installation of range hoods, pay attention to the size of the hood and hood hood, should be coordinated and unified.
8. The installation of stove, no leakage phenomenon, use soap foam after installation to check whether it is installed

Indoor gas pipeline installation principles:
Indoor gas pipelines should be dominated by Mingfu. Gas pipelines shall be laid along the walls of non-combustible materials. When meeting with other pipelines, the following requirements shall be met:
(1) When laying horizontally parallel, the net distance should not be less than 150mm;
(2) When laying in parallel vertical direction, the net distance should not be less than 100mm, and it should be located on the outside of other pipes;
(3) When cross-laying, the net distance should not be less than 50mm.

The distance between gas pipelines and electric wires and electrical equipment shall comply with the following table.
Gas pipe and wire, electrical equipment spacing (mm)
Name of electric wire or electrical equipment Minimum distance gas pipe electric wire (unprotected) 100
Wire (with protective tube) 50
Fuse box, electrical socket, power switch 150
Meters, distributors 300
Wire crossing 20
Special circumstances When the indoor gas pipeline must pass through the bathroom, toilet, ceiling (vertical wear) and living room, the pipeline should have no interface.
Indoor gas pipes should not cross below the bucket. When it is necessary to cross, additional casing should be installed. The diameter of the casing pipe should be larger than that of the gas pipe. The gas pipe and the casing should have no interface. Both ends of the casing should extend 20 to 20 mm from the side of the water bucket.
After the completion of gas pipeline installation, tightness test should be done. The test pressure is 300mm water column, and the pressure does not drop to be qualified within 3 minutes.
The burning appliances, electric meters and electrical equipment should be set up in a wrong position. The net distance between them should not be less than 500mm. When it can not be dislocated, there should be thermal protection measures.
When the wall surface of the burning appliance installation site is wood or other flammable materials, fire prevention measures must be taken.
The distance between the sides of various types of burning appliances and walls, buckets, door frames, etc. and the distance between burning appliances and burning appliances should not be less than 200mm. When the two burning appliances or a burning appliance and water bucket are arranged at right angles, the sum of the two sides of the inlet and outlet walls shall not be less than 1.2m.
When the burning appliance is set by the window, the burning appliance face should be lower than the window and not less than 200mm.

Gas rapid water heaters should be installed in well-ventilated toilet rooms, separate rooms or well-ventilated passageways. The height of the room should be greater than 2.5m and meet the following requirements:
1. Directly vented water heaters are strictly prohibited to be installed in bathrooms or toilets; flue-type (forced) and balance-type water heaters can be installed in bathrooms, but bathrooms with flue-type water heaters should not have a volume less than the rated hour consumption of water heaters. 3.5 times the amount of gas.
2. The water heater should be set in a location where it is easy to operate and maintain, and it is not easily bumped. The width of the space before the water heater should be greater than 800mm, and the distance from the side to the wall should be greater than 100mm.
3. The water heater should be installed on a sturdy and refractory wall. When it is set on a non-fire-resistant wall, it should be lined with insulating refractory material on the back of the water heater. Its thickness is not less than 10mm, and the shell over the water heater exceeds 100mm on each side. . Water supply pipes for water heaters should be connected by metal pipes (including metal hoses). The upper part of the water heater shall not have electric wires or electrical equipment. The horizontal distance between the other side of the water heater and the electrical equipment shall be greater than 300mm. When it cannot be done, insulation measures should be taken.
4. The distance between water heaters and wooden doors, windows and other combustibles should be greater than 200mm. When it cannot be done, thermal insulation and flame retardant measures should be taken.
5. The installation height of the water heater should meet the requirements of 1500mm of the fire exit hole.

The exhaust method of the water heater should be selected correctly according to the smoke exhaust characteristics of the water heater.
(1)Directly vented water heaters A room equipped with a direct vented water heater should have a vented window with a net area not less than 10 cm2/mJ on the upper part, and a 2.5 m2/MJ air intake on the lower part of the door; exhaust fans should be used. Wind, air volume should not be less than 10m3/MJ.
(2) Flue-type water heaters are equipped with a flue-type water heater, and the upper and lower air inlets are required to be installed with a direct exhaust type.
(3) Balanced water heaters The inlet and outlet of a balanced water heater should be completely exposed outside the wall. When passing through the wall, the gap between the outer wall and the wall of the intake and exhaust ports is filled with non-combustible materials.
