GENERAL
1.3 Description of the appliance
RTC-80 stainless steel boilers are triple-pass, condensing boilers
for installation in a boiler room. While they are designed for cen-
tral heating purposes, they can also be used in conjunction with
a suitable plate exchanger and storage tank to produce domestic
hot water.
All parts that come into contact with the combustion gases are
made from high grade stainless steel (316Ti/316L) to ensure max-
imum resistance to the corrosive action of acidic condensation.
The boiler has been designed with the combustion chamber at
the top and the multi-pipe tube bundle (smooth pipes) at the
bottom to optimize heat transfer and energy efciency and to
maximize the condensing effect.
The boiler has a high total water content allowing effective tem-
perature stratication between its top and bottom sections. This
allows outgoing water to reach the set temperature quickly while
maintaining the condensing effect and maximizing the water
heating dwell time around the tube bundle.
RTC-80 boilers feature a low back-pressure combustion chamber
for smoother burner operation, and low backpressure waterway
for reduced pump electrical consumption.
− High temperature resistant stainless steel turbulators are
utilized inside the tube bundle for maximum combustion
efciency.
− The boiler body is thoroughly insulated with a layer of high
density glass wool.
− The external panelling is enamel painted and internally in-
sulated with an additional layer of high density glass wool.
− The boiler’s front door and the ue gas chamber can be
easily and completely opened to facilitate the inspection,
maintenance and cleaning of internal parts and to speed
up servicing in general.
− The hinged front door can open in either direction and can
be opened without removing the burner. The door is facto-
ry tted with hinges on the left, but these can be eld-re-
versed if necessary to suit individual installations.
