IT-GB-FR mod. 740-740 ECO-740/SA-740/SA ECO-740N/SA
Directions:
The appliance is equipped with a security valve, which (in case that for any reason the
pressure of the thermal plant is exceeding 3 bar) intervenes, discharging the fluid
contained into the boiler. In order to avoid annoying outlets of water (not due to
problems of the appliance) generated by overpressure of the hydraulic plant, we
recommend to install a pressure reducing valve regulated at 1 bar, placed before the
thermal plant charging cock.
The eventual intervention of the security valve brings forth outlets of water and/or
steam, which flows on the floor, therefore the plant should be prearranged so that the
valve intervenes effectively only for real necessity and not for other causes, such as
overpressures due to an incorrect plant.
In case of outlets of the thermal plant fluid, due to the intervention of the security valve,
CORISIT S.r.l. declines any responsibility for eventual damages to floors or what else
had come in contact with the fluid.
During the operating phase of the appliance, specially at reduced heating power (owing
to the high efficiency of the heat exchanger) the combustion products, convoyed into the
chimney, may reach temperatures which may cause condense.
In order to avoid scalings and or other inconvenient due to condense, use well insulated
flues and condense collection systems, which are normally available on the market. As
forseen by the local standars.
Fast sanitary water production ( For Mod. 740 – 740ECO)
It 'should be installed in the absence of another generator ( for example a gas boiler ) a
water exchager to have larger quantities of warm water, even in hours during the
equipment is off. The sanitary fast water production is submitted to the equipment use
with cutoff cock of heating installantion open so normally not during the summer time.
Attention
: in case of fast sanitary water production, the power give to the
installation decrease.
