Powrmatic NVx LPG
The Powrmatic NVx LPG comes shipped from the factory to work on LPG gas. If you have no natural gas available on site then LPG can create an easy solution.
Generally you will need to arrange for an LPG tank to be installed, usually by your supplier. They will come to your premises and carry out a survey and discuss where the tank will be located. Another point often overlooked is the location of the upso valve. The supplier will normally pipe from the tank to the upso and locate this on an external wall. Arrange to have the upso valve located in a location where the installer can connect to it, and run gas pipe work into the building.
The upso valve (under pressure shut off) turns of the gas supply to the building, if the gas pressure falls low. This is normally caused by running out of gas in the tanks. A low gas pressure at the heater could under certain circumstances become dangerous, so all installations are protected in this way.
Powrmatic NVx LPG models are available in a wide range of outputs, from 15kW to 140kW. Remember to specify you want the heater configured for LPG, as this is a conversion carried out during manufacture. It could ship configured for Natural Gas if you don’t let us know.
Gas pipe sizing is a little different for LPG, but we have a copy of the latest, up to date charts to make sure we specify the correct sized gas main.
The Powrmatic NVx LPG heater we installed below was suspended from the ceiling using slotted channel, and suspended with 10 mm threaded rod. A horizontal flue was installed with a terminal on the outside wall.
A switch fused spur was already provided for us so we took a power feed up to the heater and to the programmer. Control as always is carried out by a Heatmiser IQ+ controller. The Heatmiser IQ+ has supported hi / lo firing so is fully compliant with ErP Jan 2018.
Gas pipe was installed in stainless steel with Geberit Mapress fittings. Gas fittings are fully compliant for LPG and Natural Gas. Stainless provides much better protection than copper and is not as attractive to thieves. Strength testing was carried out and the installation certificated for use then purged of air.
The Powrmatic NVx LPG was then commissioned by our engineer and Gas Safe paperwork raised and given to the client,
We had a cancellation on this day so two of our new apprentices installed the heater and gas main, under strict close supervision of two Gas Safe engineers. Both lads did a fantastic job and the contribution to on the job training was greatly received. Feedback from the engineers was good, they communicated and solved problems between them so fingers crossed we will have another pair of engineers in a few years time. Please note that on the job training of this type is very carefully monitored by qualified engineers, and at no point are apprentices allowed to work on the installation on their own.
