If the gas valve has been turned off for several months, there will be air in the pipe and it may take some time for this to be expelled before the pilot flame lights. After the pilot flame lights, continue holding down the bypass button for 30 seconds or so to allow the thermocouple to heat up. Then release the button.
Safety: Reason: Air Purge (startup) Before lighting the boiler burner, the air blower is operated long enough to displace 4 times the boiler combustion chamber volume. If natural gas and air are inside the boiler when the burner is lit, the boiler can explode. High Natural Gas Pressure
Turning the pilot light off will only add up to a few bucks of savings a month. If you don't mind spending a few cents a day, don't mess with it. While turning off the pilot light will only save pennies a day, there are plenty of other great ways to lower utility costs during the cooling season.
First off the pre-heat option is not used for instant hot water, they are used to provide high flow rates. The water from the pre-heat tank is added to the normal mains water hot water flow to get a greater flow rate so that these boilers can run more than one tap/shower at a time. I measured mine with the pre heat on 24/7 and then off.

If your boiler's pump is faulty, then it can cause your boiler to switch off. As a pump is used to move water around the central heating system, if it is not working properly, then hot water could just stay in the boiler rather than be moved around the system.
Gas boilers, like gas water heaters, need to cycle on and off to maintain a constant temperature. To this end, many of them have a standing pilot light, and where there's a pilot, there's always a thermocouple. The function of a boiler thermocouple is the same as that of a water heater or furnace thermocouple, and it's a simple but important one.
Hi i'm a newbie so please be gentle. I have an Ideal Classic RS40 boiler, a Randall 103 programmer and a Honeywell T6160 Thermostat. When I switch the Programmer onto constant the boiler fires up and then goes back to the pilot light after a few minutes. The boiler then won't re-ignite for at least an hour. When it does the same thing happens.
Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.
If your boiler needs to be reset, these videos show you how, whether your boiler has a dedicated reset button, an ON/OFF/SELECTOR switch or a thermostat control knob.

After a failure that causes the water level to drop and not refill, the LWCO must also fail to cause the low water condition.
A modern A-rated boiler is likely to save you as much as £300 a year on your energy bills compared to an older G-rated model (which includes most boilers using a pilot light). This saving can quickly off-set the cost of buying a new boiler, meaning you end up spending less for much more reliable central heating.
What if the pressure in my boiler is too low? The process is simple: Locate the two filling valves.; Open one of the two valves completely; Slowly open the second valve, watching how the needle (or indicator light system) on the pressure gauge responds; Let the needle reach the middle of the green zone (or the marker needle); The needle might stop at the beginning of the green zone without
Delayed ignition is a problem that's common in gas boilers that use pilot lights (as opposed to electronic ignition systems). You see, during normal operation, when a gas boiler receives the call for heat, the gas valve opens and releases a small amount of gas into a sealed combustion chamber via small "jets".
Below, we've listed the issues that can cause various sequences of light you're likely to see on your Vokèra boiler when it's broken. Red Light On and Green Light Off.

The machine still works, no issues that I can see, other than the indicator being on.
Turn Pilot Lights Off/On Seasonally Turning off pilot lights in gas fireplaces and furnaces during the summer can save a substantial amount of energy, and money. First you won't burn gas that you won't use, and second your air conditioning doesn't have to work overtime to cool off the heating effects of the constantly burning pilot light.
The only exception: old boilers equipped with a pilot light (flame) which continually consume power. For these, it can be a good idea to turn them off if you go away in the summer. 2. No risk with a modern, well maintained boiler. In Brussels, gas boilers have to undergo mandatory maintenance every two years. They are also all fitted with
You'll have to check with the burner manufacturer to find the correct minimum firing rate for your particular equipment. Only then can a qualified technician make the necessary adjustments.
