Remeha
Gas 310/610 ECO
GENERAL
These user guidelines contain useful and important
information for the correct operation and maintenance of
the Remeha Gas 310/610
ECO. Furthermore, important
instructions are given to ensure safe and trouble-free
boiler operation. Read these instructions carefully before
putting the boiler into operation, familiarise yourself with
its operation and strictly observe the instructions given.
Your installer usually supplies user guidelines for
the entire installation. Follow at first these guide-
lines (if available).
Remark: As a user you are not allowed to change any
part of the boiler.
PRINCIPLE OF THE BOILER OPERATION*
A venturi (30) is placed on the inlet side of the fan (29) ,
see fig. 01 . On heat demand the fan starts to pre-purge.
Combustion air is drawn into the boiler through the air
inlet
(19) . The incoming air is mixed optimally in the ven-
turi and later in the fan with the gas from the multiblock
(31) . The homogeneous gas / air mixture is brought to
the burner by the fan. Depending on demand (under the
dictates of flow/return sensor and other external/internal
control inputs) the boiler output is controlled.
The mixture is initially ignited by the combined ignition/
ionisation probe
(24) , which monitors the state of the
flame. The products of combustion in the form of hot
flue gases are forced through the cast aluminium heat
exchanger
(17) transferring their heat to the system
water (the flue gas temperature is reduced to approxi-
mately 5°C above the temperature of the system return
water). If the flue gas temperature decreases below
dew point (55°C) the water vapour in the flue gases will
begin to condense out in the boiler, transferring its latent
heat into the system water, increasing the output of the
boiler without increasing the gas consumption.
Condensation formed within the boiler and flue system
is discharged from the boiler to an external drain via the
drain pan / siphon
(9) supplied. The flue gases turn in
the drain pan (7) and are discharged vertically through
the flue gas connection (14) to atmosphere.
