Thanks for the question Bob, if the water is coming directly from the unit and not the connections leading to it, there may be an issue with the heat exchanger. We would recommend booking a service call to have the unit assessed. In the meantime, if you can, isolate the water supply to the unit to prevent further damage,

Thanks for the question CMF, turning off the water to the unit will be fine as long as the power to the unit is still operational so the frost protection to the unit will still work.

Thank you for the question Rory. The gas does enter the Infinity after the sparker is going, combustion should start almost instantly. There is likely to be a miniscule amount of unburnt gas able to be detected in the flue, just prior to combustion…hence the smell.

Thanks for the question Concerned, there are a few more details required to answer your question as it will depend on what model of unit the plumber has installed. We would recommend contacting our technical help desk to discuss further. They can be reached on 1300 555 545 option 3.

Thanks for the question Michael, it is hard to diagnose the issue with the unit without inspection. We would recommend calling out technical help desk on 1300 555 545 with the model and serial number of the unit. You can find this information on the left hand side of the unit on a data plate. The help desk can advise if the unit has any warranty left.

Thanks for the question Sweetjustice, the B20 cannot be run without power.

Thanks for the question Page. It's hard to confirm without inspecting the unit to see what has caused the issue. It may be just the fuses or something more in depth. We do hold a huge stock of replacement parts for these units so we would recommend booking a service call and having a technician take a look for you. Our service team are available on 1300 555 545.

Thanks for the question Moni, if all the filters have been cleaned the unit may need a service call to diagnose the issue. The unit does require a certain amount of water flow in order for the unit to work. Sometimes a build up on the taps or shower heads can also restrict the flow of water coming through the outlet.

Thanks for the question Paul and Lee. The INFINITY unit does not require a tank for operation as the hot water is not stored in the unit. Rather when a tap is opened the unit starts and the hot water is produced on demand. When the tap is turned off the unit stops operation. The capacity mentioned is the amount of water the unit can produce at a 25 degree rise.

The only difference between the 2 models you have mentioned is the maximum temperature the unit can achieve. INF20N50M is a 50 degree limited unit which complies to the regulation for hot water delivery to bathroom areas. INF20N60M is a 60 degree limited unit, this unit may require a tempering valve to the outlets in the bathroom areas. Your installing plumber can advise if this will be require for your property.

Unfortunately we cannot advise if a pipe upgrade will be required as it will depend on the area and the other gas appliances at the property. Your installing plumber will be able to advise if this upgrade is needed. Depending on the model of INFINITY the pipework may need to be replaced with a wider pipe to allow more gas to the appliance. It is very important that the gas supply to the unit is sufficient and takes into consideration all appliances that may be running at the same time. If the gas flow to the unit is insufficient it will lead to problems with the supply of hot water.
