Maintenance information
Donotuse(forcleaning,polishing,etc.)orstoresprays,solvents,chlorinatedcleaning
agents,paints,lacquer,adhesives,salts,etc.onorinthevicinityofthegasredboiler.
Underunfavourableconditions,thesematerialsmayleadtocorrosionintheboilerand
theuegassystem.Ductedventsroutedthrougharoofmayalsocontaincorrosive
vapours.
Caution - ignoring this rule may lead to a risk of re as well as a risk of
destruction, poisoning or explosion.
Corrosion protection
- Yourgasredboilershouldonlybeinstalledandmodiedbyanapprovedheating
contractor,asonlytheyhavetheessentialknowledgetocarryoutsuchwork.
- Gascomponentsmustnotbemodied.
- Never close or restrict the ventilation apertures in doors or walls when
operating the boiler in the open ue mode; only start the boiler when the ue
has been fully installed.
- Only operate the boiler in balanced ue mode, after the balanced ue system
has been fully installed and the wind protector is not covered up.
- Thegasredboilermayonlybeinstalledinroomsthatareprotectedfromfrost.
- Neverisolatetheboilerfromthepowersupplywhenoutsidetemperaturesfallbelow
freezing,asotherwisethereisariskofthesystemfreezing-up.
- Donotmodifythedrainorthesafetyvalve.
Caution - ignoring this rule may lead to a risk of re, as well as a risk
of destruction, poisoning or explosion.
Do not use or store explosive and ammable materials, e.g. petrol,
thinners, paints, paper, etc. inside the boiler room.
Positioning / modications
Energy, and therefore operating costs, can be effectively saved through low DHW
temperatures.Furthermore,scalingupoftheat-plateheatexchangerinthegascombi
boilerversioncan be prevented. If the water’s hardness is greater than 15°d.H. the
cylinderwatertemperatureshouldbelimitedto55°C.
