Glass built-in hobs are designed for household use and are not recommended for commercial purposes such as catering, food stalls, or restaurants. 

A safety device functions to prevent gas leakage in the event that the flame is extinguished due to wind or food spills. Without a safety device, the risk of gas leakage is significantly higher.

To minimize this risk, Rinnai incorporates safety device technology in most of its built-in hobs. For models that are not equipped with a safety device, Rinnai designs ventilation holes in the lower body of the hob to allow sufficient oxygen intake, ensuring safer combustion during use.

It is safe to use most cookware sizes, except for BBQ plates and conventional oven pans (stove-top oven)

Built-in hobs and cooker hoods use Stainless Steel SUS 304, while portable stoves use Stainless Steel SUS 430.

A yellow flame indicates incomplete combustion, which may be caused by a dirty burner or poor air circulation in the room.

Rinnai built-in hobs feature three types of burner layouts: 

• Unique Shape

Designed to suit Asian cooking habits. The left burner is intended for large pots and wok cooking, while the two burners on the right are positioned diagonally, allowing simultaneous use with smaller cookware.

Examples: RB-93UG, RB-3SS-C

• Mountain Shape

Inspired by a mountain-like layout. This design allows the use of two large pots on the left and right, with a smaller pot in the center. Recommended for European-style cooking, which typically involves multiple smaller portions.

Examples: RB-773RO(G), RB-7513D(G)

• T-Shape

Features one large burner and two smaller burners (top and bottom). The overall size is more compact compared to other layouts, making it suitable for everyday use in limited spaces. 

Rinnai uses a parallel ignition system, where both igniters operate simultaneously, but only the burner corresponding to the turned knob will ignite.

(Except for models RB-782/783G(B) and RB-772/773RO(G))

Proper maintenance is simple. For long-term use, regular cleaning is recommended by following these guidelines:

• Do not clean the hob immediately after cooking; wait until it has cooled down 
• Clean using warm water mixed with a small amount of mild detergent applied to a soft sponge 
• Use a toothbrush or soft scrub sponge for stubborn dirt 
• Ensure that the burner ports are completely dry after cleaning 
• To avoid damage, do not use cleaning agents containing soda, alkali, ammonia, acid, or chloride, solvent-based cleaners, stain/rust removers, or abrasive cleaners (such as powder or cream cleaners)

Please ensure proper spacing as follows 

• Distance between hob and oven: 30 mm (3 cm) 
• Distance between oven and side/back walls: 45 mm (4.5 cm) 
• Distance between oven and cabinet (if no hob above): minimum 50 mm (5 cm) for ventilation

For apartment living, the Domino Series is recommended, including models RB-311N(GB), RB-312N(GB), RB-3311S(GBS), and RB-3312S(GBS).

These models are available in 1- and 2-burner variants, feature compact dimensions (31 x 52 x 13 cm), and have a vertical design suitable for limited spaces.

The RB-72G is one of Rinnai’s best-selling built-in hobs due to several advantages: 

• Part of the Ideal Hob Series, with dimensions suitable for typical household use (77 x 46 x 14.7 cm) 
• Strong and stable flame power of 4.3 kW 
• Burner head made of hot-forged brass with ceramic coating, making it more durable and resistant to discoloration

• RB-772RO(G): 2 burners with gas consumption of 3.2–3.2 kW
• RB-773RO(G): 3 burners with gas consumption of 3.2–1.2–3.2 kW

These models feature an aluminum frame with a Top Air Intake System. This system draws oxygen from the top of the hob, helping to maintain a stable flame even when the cabinet door below is open, and reducing the risk of flame extinguishing.

They also use a combination of an aluminum frame and 8 mm thick glass.

The RB-93UG is a 3-burner built-in hob with two high-power burners and one medium burner, with gas consumption of 4.3 kW – 4.3 kW – 1.7 kW.

The burner heads are made of brass with a ceramic coating, making them easier to clean and more durable. The pan supports and wok adaptors are made of cast iron.

There is no fixed usage limit as long as the product is used properly in accordance with the user manual. Based on user experience, built-in hobs can remain safe to use even after 8–10 years of use.

There are several differences between these two types of electric cooktops, such as:

• Heating Method

Vitroceramic: Uses heating elements; the burner surface glows red and becomes hot 

Induction: Uses electromagnetic induction; the surface does not glow red and only becomes warm 

• Cookware Compatibility

Vitroceramic: Can use various types of cookware as long as the base is flat and heat-conductive (e.g., iron or aluminum) 

Induction: Requires specific cookware that is compatible with electromagnetic induction (has an induction base)

The advantages of these Rinnai cooktops compared to other brands include:

• Equipped with a Child Lock Safety Device to minimize accidents caused by unintended use 
• Uses high-quality glass from Schott Germany, backed by a lifetime warranty 
• Features a Residual Heat Warning system that alerts users when the cooktop surface is still hot

Before using an induction cooktop, please consider the following recommendations when selecting suitable cookware:

• Use cookware made of magnetic materials or specifically designed for induction cooktops
• Recommended materials include enamel-coated steel or cast iron
• Not recommended: cookware made of non-magnetic stainless steel, aluminum, glass, ceramic, or clay
• Choose cookware size that matches the burner size, such as:

• 3011, 3022 & 5022 : 60 kg
• 7012 & 7013 : 80 kg
• 6024 : 100 kg

* Applicable to induction and vitroceramic cooktops, with glass covered by a lifetime warranty.

Rinnai induction cooktops are equipped with power levels from 1 to 9, allowing you to adjust the heat according to your cooking needs.

For safety, the cooktop is designed with an automatic shut-off feature that will turn the unit off if it is used continuously for a certain period of time.

The following is a usage guide based on power levels on an induction stove:

• Allow the cooktop to cool down to room temperature
• Use a soft cloth to dry the surface after cleaning with water (to prevent water stains)
• Use cleaning products specifically designed for ceramic, steel, or stainless steel surfaces

Using a cooker hood is highly recommended for the following reasons: 

• Filters air and smoke from cooking to keep the room air clean and healthy 
• Removes heat and steam to prevent the kitchen from becoming stuffy 
• Allows cooking at any time, as Rinnai cooker hoods are equipped with built-in lighting 
• Enhances the kitchen’s appearance, making it more elegant and modern 

Rinnai cooker hood technology can reduce odors in the room by approximately 80–90%.

Chimney series is designed for larger and more spacious kitchens, while slim series is suitable for smaller or minimalist kitchens.

All Rinnai cooker hoods offer two exhaust modes, ventilation and recycle. 

Ventilation: suitable for kitchens with poor air circulation (expels air outside)

Recycle: suitable for kitchens that are rarely used or dry kitchens; works by filtering and recirculating cleaner air back into the room

Dirty aluminum or charcoal filters need to be replaced. For models using baffle filters, the filters can be cleaned. Replacement or cleaning is recommended every 6–12 months.

The maximum distance is 10 meters, with a maximum of 2 bends in the ducting pipe.

The required diameter varies depending on the type of cooker hood, whether slim or chimney. Slim type requires a 5-inch diameter with a pipe length of 40 cm, while Chimney type requires a 6-inch diameter with a pipe length of 40 cm

You can measure it using a Sound Level Meter (SPL Meter).

The RH-S3059-PBW is one of Rinnai’s best-selling models due to its slim design, strong suction power (up to 600 m³/h), and LED lighting with LED strip for better visibility. 

The RH-KT2959-GBV features low noise operation with strong suction power up to 1,300 m³/h and power consumption of 220 watt.

Slim: 220–600 m³/h

Chimney: 1.000–1.300 m³/h

RH-C2859-SSW offers suction power up to 1,200 m³/h.

A charcoal filter is required when using the Recycle system. It is not needed for the Ventilation system. For example, RH-KT2959-GBV does not require a charcoal filter as it only supports ventilation.

• Clean the baffle filter and oil pack by soaking them in hot water, then gently scrub with a toothbrush
• Check the charcoal filter. If it becomes sticky and no longer makes a sound, it should be replaced

Plasma filter technology can remove up to 98% of odors, smoke, allergens, and pollutants from cooking. It effectively eliminates grease particles in the air, ensuring cleaner and fresher air circulation.

Plasma fresh: absorbs, purifies, and releases clean air back into the room

Plasma cluster: Emits positive and negative ions to remove odors, bacteria, mold, allergens, and reduce viruses.

It filters oil residues, smoke, and airborne particles.

This feature allows the hood to continue operating for a few minutes after being turned off, then automatically shuts down. It ensures that remaining smoke, odors, and steam are fully extracted.

• Level 1: 5 minutes
• Level 2: 10 minutes
• Level 3: 15 minutes
• Level 4: 20 minutes

An electric water heater uses electrical power as its heat source and can store water in a tank, while a gas water heater uses gas (LPG) as its heat source, and the hot water is distributed directly to the tap without being mixed with cold water.

• Prepare a piping line in the bathroom for water circulation, which must use special pipes that can withstand high temperatures.
• Make sure the water pressure is suitable. If the pressure is low, use a booster pump.

• Flexible hoses (1 for hot water & 1 for cold water)
• Double napple
• Stop valve
• Mixing valve (faucet)
• Gas regulator & hose (for gas water heaters)
• Power outlet (for electric water heaters)

* bathtub requires a minimum capacity of 80 liters.

The estimated refill/reheating time is 1–3 hours, depending on the tank capacity and the power rating of the water heater.

Yes, it can be used for multiple bathrooms simultaneously by choosing a capacity of 40–100 liters, with the following considerations:

• Installation should be outside the bathroom and supported by a booster pump to ensure stable water flow
• The water temperature may decrease depending on the pipe distance; the longer the distance, the lower the heat at the outlet
• Tank capacity should be selected based on the number of bathrooms and estimated usage, approximately 10–15 liters per person per use

• The Gold Series features gold-colored details, giving a more luxurious and elegant appearance
• Equipped with AG+ technology at the inlet and outlet, which helps eliminate bacteria and harmful germs, making the water cleaner and safer
• Inner tank material of RES-EC is Titanium Enamel, while RES-A is Sapphire Enamel. 

Every Rinnai water heater is equipped with an Overpressure Safety Device, which helps maintain stable water pressure.

With this feature, Rinnai water heaters can withstand pressure up to 7 bar. If the pressure exceeds 7 bar, the system will automatically reduce it to a safe level.

• If installed inside a bathroom, use a flexible pipe to vent combustion exhaust to the outside 
• It is recommended to install the unit and gas supply outside the bathroom, under a roof to protect it from rain 

Rinnai gas water heaters offer several advantages, including:

• Direct shower: Produces hot water instantly without mixing with cold water 
• Anti-leaking gas sensor: Cuts off the gas supply if the burner flame suddenly goes out, preventing gas leakage

low are the common flame colors you may find on a Rinnai gas stove

• Blue: Indicates proper combustion and is safe for use 
• Yellow: Indicates incomplete combustion, usually caused by insufficient oxygen or a dirty burner 
• Red: Typically caused by dust covering the burner or high humidity in the environment 
• Green: Indicates the presence of certain chemicals during combustion (e.g., vinegar or cleaning agents)

• A flame shape designed to go straight upward rather than spreading sideways 
• Smaller burner diameter 
• Shorter distance between the burner and the cookware 
• Using appropriately sized (smaller) cookware

Yes, however, replacement is only possible for certain models, namely 511, 522, 302, and 602. The burner is not included in the purchase package and must be purchased separately through a Rinnai Service Center.

For stoves with a ceflon-coated body, replacing it with a high-power burner may cause the body to wear out more easily. Therefore, it is more recommended for stoves with a stainless steel body.

For models other than those mentioned, burner replacement is not possible due to differences in spare part dimensions and incompatible input, which may result in unstable flames.

Each burner can support up to 25 kg. Therefore, the total maximum load for a two-burner gas stove is 50 kg.

The difference between the two products is based on gas consumption.

• Gas consumption of TL-287RI: 6.2 kW
• Gas consumption of TL-289RI: 9.8 kW

The most significant difference is that the RI-522AT is equipped with a timer feature, while the RI-522A does not.

The timer can be set from 5 to 60 minutes and functions as a reminder. To use it, turn the knob one full rotation clockwise, then turn it back to the desired time setting. This method helps produce a longer timer alert sound.
