The gas stove is the most-used station in any commercial kitchen. It generates the most heat, handles the most orders, and takes the most abuse. Choosing the wrong configuration means wasted fuel, slow cooking during rush hour, or unnecessary safety risk. CHINENG offers two commercial gas stove series — the 8138 Startup Series and the 8158 Chain Series — each available in LPG and natural gas variants, from 0.6 m to 1.8 m widths, with flame failure protection standard on every unit.

1. LPG vs. Natural Gas — Know Your Fuel

This is not a feature preference — it is an infrastructure decision. Your gas type determines which model you need, and the two are not interchangeable without replacing burner nozzles.

	LPG (Liquefied Petroleum Gas)	Natural Gas (NG)
Fuel source	Bottled gas (tanks)	Piped supply
Heat output	Higher per volume	Lower per volume
Running cost	Higher per BTU	Lower per BTU in most markets
Flexibility	Portable, easy to relocate	Fixed to gas line location
Best for	Rentals, food trucks, areas without gas infrastructure	Permanent install, existing gas line
Conversion	Different nozzles required	Different nozzles required

CHINENG offers each model in both LPG (SZCY28) and natural gas (SZCT26) variants. Confirm your fuel source before ordering — converting between LPG and NG requires different burner nozzles on most stoves.

2. Two Series: 8138 Startup vs. 8158 Chain

CHINENG produces two commercial gas stove lines — the 8138 Startup Series and the 8158 Chain Series. Both include flame failure protection as standard. The difference is in build quality, heat retention, and duty cycle.

8138 Startup Series

Designed for first-time restaurant owners, pop-ups, and small kitchens. 220 V / 120 W electrical assist. Body weight ranges from 25 kg (0.6 m) to 60 kg (1.8 m).

Size	Best For	Dimensions (mm)	Net Weight
0.6 m	Solo chef, takeout counter	600×700×800+250	25 kg
0.88 m	Small dine-in (10–20 seats)	880×780×800+250	35 kg
1.3 m	Dual-burner, growing business	1,300×780×800+250	50 kg
1.5 m	Full menu, parallel cooking	1,500×780×800+250	55 kg
1.8 m	High output, wider kitchen	1,800×780×800+250	60 kg

8158 Chain Series

Built for multi-location chains, busy diners, and continuous-operation kitchens. Heavier stainless steel construction, deeper burner bases for sustained high heat. Body weight from 38 kg to 72 kg.

Size	Best For	Dimensions (mm)	Net Weight
0.6 m	Compact chain outlet	600×750×800+275	38 kg
0.88 m	Standard single-burner station	880×800×800+275	42 kg
1.3 m	Dual-burner, high-efficiency kitchen	1,300×800×800+275	69 kg
1.5 m	Continuous service kitchen	1,500×800×800+275	71 kg
1.8 m	Flagship store, central kitchen	1,800×800×800+275	72 kg

3. Single-Tail vs. Dual-Tail Configuration

The "tail" is the rear warm-holding area of the stove. It determines how many finished dishes can be kept warm while the next batch is cooking — and in a busy kitchen, that matters more than most buyers expect.

	Single Tail	Dual Tail
Warm-holding area	One shelf behind burner	Two shelves / wider area
Best for	Individual dish finishing	Multi-dish plating from same chef
Kitchen type	Small to medium restaurants	Chain stores, fast-casual, high volume
Example config	0.88 m model (1 burner + 1 tail)	1.5 m – 1.8 m models (2 burners + 2 tails)

For chain restaurants where speed of service is measured in seconds, dual-tail configurations are nearly mandatory. The 8158 Chain Series in 1.5 m and 1.8 m widths includes dual-tail layout as standard.

4. When to Choose Each Series

Choose the 8138 Startup Series if:

• This is your first restaurant or you are opening a small outlet.

• Budget is a primary concern but you will not compromise on safety (flame failure protection is standard).

• Your kitchen volume is under 200 covers per shift.

• You need a 220 V single-phase connection (no 380 V required).

Choose the 8158 Chain Series if:

• You operate multiple locations or plan to scale.

• Your stove runs 12+ hours daily and needs to withstand continuous abuse.

• You need maximum heat output and faster recovery between orders.

• Your kitchen serves 300+ covers per shift with significant peak-hour load.

5. Installation Requirements

Gas supply: Dedicated LPG or natural gas line with appropriate regulator. Connection must be performed by a licensed gas fitter.

Electrical: 220 V single-phase, 120 W per burner for ignition and controls. Standard plug included.

Space: Allow 10 cm clearance on both sides and 15 cm behind the unit for ventilation. The +250 mm or +275 mm dimension indicates backsplash height above cooking surface.

Floor: Operating weight ranges from 25 kg to 93 kg depending on model. Ensure level surface capable of supporting the load.

Ventilation: Commercial kitchen exhaust hood is required above all gas cooking equipment by most fire and building codes. Consult your local authority.

6. FAQ

Q: Can I convert an LPG model to natural gas later?

Not without replacing burner nozzles. CHINENG models come in dedicated LPG (SZCY28) and NG (SZCT26) variants. Order the correct variant for your fuel source from the start.

Q: How many burners do I actually need?

Count your menu items that need live-fire cooking simultaneously. Two or fewer? A single-burner 0.88 m is enough. Three or more at once? Go with a 1.3 m or wider dual-burner model.

Q: Is a wider stove always better?

No. A 1.8 m stove with only one chef creates unused space that collects grease. Match the stove width to your staffing, not your ambition.

Q: What is the lifespan of a commercial gas stove?

With daily cleaning and annual maintenance, 8–12 years in continuous use. The 8158 Chain Series uses thicker stainless steel and is designed for longer service life.

Q: Is flame failure protection mandatory?

In most countries, yes. It is also standard on every CHINENG gas stove model regardless of series or price.

Choosing the right gas stove comes down to three things: match the size to your volume, pick the gas type your building supports, and never compromise on flame failure protection.
