Pressure drop at the simultaneous load
All the brillers are on, and the flame at the endpoints can be weakened, and the manifold and regulator capacity is verified.
For Professional gas range cooker, the applicable CE scope is determined from intended use, energy sources, safety architecture and target market. The risk assessment, technical file, testing and conformity route must be verified against the actual model.

The top of the cooker can have open brillers or a single piece of hot plate (solid ball), gas oven at the bottom. The quick load change of the hob eyes and the long operation of the oven under thermostat control share the same gas path. When all functions are open, the manifold pressure, flame stability and body temperatures can reach the most negative state.
The oven door opening, closing the top surface of the large pot or changing the combustion air of the drum pull can be a simple task for the user to understand which brush a button controls; the associated gas path should be securely closed when the flame is extinguished. The oven thermostat, the top oven faucets, the pilots and, if any, the electric ignition are marked so as not to be mixed during maintenance.
The cousin family can have four, six or eight eyes; different oven volume and power options. When the family is set up, the total load, beam cut, manifold diameter and air clearance are compared alongside the common parts. If the target country gas categories change, the injector, setting and label matrix are prepared.
The following data shows why even models with the same product name can change the path of conformity.
The protective, control and verification approach shall be based on the actual product cycle.
All the brillers are on, and the flame at the endpoints can be weakened, and the manifold and regulator capacity is verified.
The shut-off volume shall be tested for gas disconnection and safe restart behaviour after failure to fire.
Numerous buttons can cause the wrong briller to open; location and permanent markings are evaluated.
Long-term operation of the upper and lower functions can increase the temperature of valves, hoses, cables and insulation.
The discharge of the oven shall not adversely affect the upper briller air or the operator area.
If the leaked parts of the briller are attached incorrectly, the burn changes; physical locking and instructions reduce the error.
A single product name doesn't give the same answer for all models.
| The subject | The situation | Product-based evaluation |
|---|---|---|
| GAR 2016/426 | YES, YES | It's a general professional kitchen appliance. |
| Authorized organization | YES, YES | Type and serial production conformity shall be carried out by a third party according to GAR modules. |
| The machine's layout | IT 'S A MESS . | The scope of the change in the EU/EEA is designated if the fan or motor accessory creates dangerous movement. The change in the EU/EEA includes 2006/42/EC, which applies from 20 hob 2027, including (EU) 2023/1230. |
| EMC | IT 'S A MESS . | If there's an electronic ignition or digital control, it's evaluated. |
| PED | NO , NOT AT ALL . | The standard low-pressure gas pathway does not automatically generate PED. |
| ATEX | NO , NOT AT ALL . | Normal kitchen use is not the purpose of explosive device. |
ISO management system certification does not replace product-specific risk analysis, test evidence and compliance file.
The top brillers, oven, pilot, fan and ignition options are defined in the single device model tree.
The interaction of the manifold, total load, air gaps and combustion product pathways is studied.
The configuration that represents the family is warranted in terms of eye count and oven power.
The approved organization plans GAR evaluation and production oversight.
The label, category, guide, EU Statement of Conformity and list of critical parts are compared for the last time.
The hob and the oven variants are studied as a common device.
Compare the top coverage or other similar risk architecture.
If it is marketed as a single unit, it is evaluated at the unit level; the specific requirements of the stove and oven are met separately.
No, the risks of open burners being fired, burned, solid, and temperature also need to be proven.
The effect is assessed if the total load, manifold pressure, air and temperature change; the current type is not assumed to be automatically covered.
No. The function of gas cooking remains within the scope of GAR, and the additional risks of the fan are addressed by appropriate legislation and standards.
All briller injectors, settings, category label, service step and final safety check are connected to a defined conversion procedure.
The range is calculated by looking at the eye-burning configuration, gas categories, number of countries, available tests, sample and monitoring mode.
