Below you'll find answers to the questions we get asked the most.
Why does the pilot flame not light up on my burner ?
Are the quick connectors from the ignition transformer good connected?
Do you see a spark at the peek window when igniting?
Do the pilot valves open, do they get energized?
Any cracks present in the ignition cables?
We have a flame failure, can I do something ?Are the wires tightly connected on the flame sensor?
Did you check if the UV/IR flame sensor eye is clean?
Is it correctly installed after cleaning, pointing towards the flame direction?
Do I need a water treatment program for my boiler system ?
This depends on the water quality of the water that is used to fill. In a new boiler installation; you should always let your water analyse prior to filling the system, this will show if you have to apply pre-water treatment or chemical additives to reach optium results. Periodically monitoring of the system water is recommended, typically every 6 months to avoid boiler scale, corrosion and biological fouling. In practice; most boiler systems require some form of water treatment.
What is the function of a shunt pump on our boiler installation?
The temperature distribution of the water in the boiler is affected by the return water that comes back into the boiler. The shunt pump is used to ensure that the temperature differences in the boiler are minimized.
- To avoid temperature stresses in the boiler structure.
- Avoiding condensation in the flue gas-carrying part of the boiler.
- Optimum use of the buffer capacity present in the boiler.
The shunt pump is continuously circulating (at least three times the boiler vessel volume per hour) it takes relatively cold water from the bottom of the boiler to the top of the boiler, where it will be mixed with the hotter water on top. In doing so the shunt pump causes an as uniform as possible temperature distribution in the boiler. This leads to minimal maintenance and a maximum lifetime of the boiler.
I have put salt in my water softener brine vessel frequently, do I still need to let it service ?
