Description of the appliance

TAU N OIL PRO R steel boilers are triple flue pass, condensing
boilers for installation in a boiler room. While they are designed
primarily for central heating purposes, in conjunction with a
suitable storage cylinder they can also be used to produce do-
mestic hot water.
They are suitable to operate with fuel oil burners.
The parts of the boiler that are in contact with combustion prod-
ucts are made entirely of highly alloyed stainless steel, capable
of providing the best possible resistance to corrosion caused by
acid condensate.
The boiler has been designed with the combustion chamber at
the top and the smooth pipe tube bundle at the bottom to opti-
mise heat exchange and energy efficiency and to maximise the
condensing effect.
The boiler has a high total water content which is differential-
ly distributed between its top and bottom sections. This al-
lows outgoing water to reach the set temperature quickly while
maintaining the condensing effect and the water heating time
around the tube bundle for as long as possible.

Combustion chamber
TAU N OIL PRO boilers feature lightly pressurised combustion
chambers for a smoother burner action, and high temperature
resistant, stainless steel turbulators inside the tube bundle for
maximum burner efficiency.
The boiler body is thoroughly insulated with a layer of high den-
sity glass wool.
The paint finished external panelling is also internally insulated
with a layer of high density glass wool.
The boiler's front door and the flue gas chamber can be opened
completely to facilitate the inspection, maintenance and clean-
ing of internal parts and to speed up servicing in general.
The front door can open in either direction and can be opened
without removing the burner. The door is factory fitted with
hinges on the left, but these can be reversed if necessary to suit
individual installations.
