3.7 - CONNECTION TO SAFETY HEAT
EXCHANGER DRAIN
Solid fuel fired boilers have to be installed
with the safety devices foreseen by
applicable
regulation and laws.
For this purpose the GASOGEN G3 2S
boilers are fitted with a safety heat
exchanger.
On this safety heat exchanger the installer must fit a heat
discharge valve , whose control bulb has to be inserted in the
bulb holder placed onto the rear wall of the wood fired boiler.
The inlet and outlet connections can be inverted.
However we recommend that the valve be fitted on the cold
water inlet.
In correspondence of the safety heat exchanger
outlet, we recommend fitting a drainage pipe
with a funnel and siphon that lead to an
adequate drainage. The drainage has to be
visible.
Warning!
In absence of this precautionary measure, the eventual
intervention of the heat discharge valve could cause
damages to people, animals or property. The manufacturer
shall not be held liable for any such injury and/or damage.
3.8 - RECIRCULATION PUMP
For correct boiler operation it is necessary to
install a recirculation pump in the boiler.
The recirculation pump, supplied as an
optional kit in two different versions, basic or
for buffer storage tank control, will have to be
connected as shown in figs. 19 and 20.
If the recirculation pump is not installed, besides limiting
the boiler’s life span, it will invalidate the warranty.
WARNING!
The hardness of the mains water supply conditions the
boiler’s life span.
Depending on the hardness of the of the mains water
supply the possibility of installing a water
softener has to be taken into consideration.
In hard water areas where the main water can exceed 15°f
total hardness, water treatment is always recommended.
