Frequently Asked Questions - RB-72S Rinnai

How do I clean the stainless steel top of my RB-72S hob?

Allow the hob to cool completely. Use a soft sponge with warm water and a little washing-up liquid. For stubborn stains, use the scouring pad on the back of a sponge, applying even pressure following the grain of the stainless steel. Dry with a soft cloth to avoid water marks.

What should I do if the burner does not ignite?

First, check that the battery is not drained; replace with a new D-size 1.5V battery if needed. Ensure the burner components are clean and dry, and that the ignitor electrode gap is correct. Also verify that the gas supply is turned on and the gas cylinder is not empty if using LPG.

How do I assemble the big burner after cleaning?

Place the burner body onto the ventury, ensuring the thermocouple and electrode extend through their respective holes. Position the burner head onto the burner body. For the big burner, no simmer ring is used. Ensure all parts are correctly seated and aligned.

Can I convert my RB-72S from Natural Gas to LPG?

Yes, conversion is possible but must be carried out by a qualified technician. The manual provides instructions: remove the nozzles and replace with the correct ones for LPG, install the LPG adaptor, and perform a leak test. Contact your local Rinnai service center for assistance.

Why does my hob make a whistling noise when operating?

A slight whistling noise is normal and indicates that the burner is operating correctly. It is caused by the gas flow and does not signify a malfunction.

What type of pans should I use on this hob?

Use pans with thick, flat bases for even heat distribution. The pan diameter should match the burner: for the big burner, use pans between 10 cm and 22 cm in diameter. Avoid pans that are too small (unstable) or too large (flames spreading beyond the base).

How do I replace the battery for ignition?

The battery compartment is located at the bottom of the hob, accessible from the front. Insert a new D-size 1.5V battery (not included) with correct polarity. If the hob will not be used for a long time, remove the battery.

What is the correct cut-out size for installation?

The cut-out dimensions must be between 650–730 mm width and 350–410 mm depth, with a corner radius of R120. Ensure the worktop is heat-resistant and at least 30–40 mm thick. Follow the installation guide for precise measurements.

Why does the flame appear uneven?

An uneven flame is usually due to dirty burner grooves or incorrectly positioned burner components. Disassemble the burner, clean the grooves on the burner head and body with a soft brush, and reassemble correctly. Ensure the burner cap is securely placed.

How do I properly turn off the hob?

Turn the control knob clockwise to the 'off' position (symbol 'o'). This stops the gas flow and extinguishes the flame. Wait a few seconds for the safety device to deactivate (you may hear a 'thud' sound). Always ensure the flame is completely off before leaving.

Operation

Regulating the Flame

Two identical illustrations of a cooking pot and a windmill, both without any text or symbols.

The burners can be regulated at any level between the highest and lowest flame.

Control the flame so that it does not spread out beyond the sides of the pan. As the outer part of the flame is much hotter than the centre, the tips of the flames should stay beneath the pan base. Flame tips which extend beyond the sides of the pan merely warm up the air in the room and can also damage pan handles and increase the danger of injury

Switching OFF

Turn the control clockwise to position "o"

This stops the flow of gas and the flame goes out

Warnings

• It is normal to hear a slight whistling noise while the burner is operating.
  When it is first used for the first time, it is normal for the burner to give off odours; this does not pose any risk and does not indicate a malfunction; the smell will be gone over the time.
  A few seconds after the burner is switched off, a sound (thud) will be produced. This is not a fault - this means that the safety device is no longer operating.
• Keep the burner as clean as possible. If the ignitor are dirty they will not light properly. Clean them periodically using a small non-wire brush. Rear in mind that the ignitor must

Cleaning and Care

Cleaning and Care

The appliance should be cleaned after each use. Allow the appliance to cool down to a safe temperature before cleaning.
To avoid water marks and lime scale deposits, use a soft cloth to dry surfaces that have been cleaned with water.
- Stubborn soiling should be soaked first.
- Food which boils over onto the hot hob can cause the burner components and the stainless steel surface of the hob to discolour. Remove any soiling immediately.
The surfaces of the burner components will become more matt with time. This is quite normal and will not affect the operation of the hob.

To avoid damaging the surface of your appliance, do not use:

• cleaning agents containing descaling agents, soda, alkaline, ammonia, acids or chlorides
• stain or rust removers
• abrasive cleaning agents, e.g. powder cleaners and cream cleaners
• solvent-based cleaning agents
• dishwasher cleaner
