Connecting the heating system

NOTICE: Boiler damage due to moisture.
▶ Protect the components of the gas ignition system
from moisture (dripping, spray, rain) during
installation of the boiler, during operation and during
maintenance work (such as replacing the pump,
replacing the control, etc.).
NOTICE: System damage due to overheating as a result
of a low water condition.
▶ Note that a boiler installed above the level of the
heating system must be equipped with a low-water
cut-off. The low-water cut-off must be installed during
installation of the boiler and placed above the water
level in the boiler without any means of shutting the
water off between the boiler and low water cut-off
( figure 8).
NOTICE: System damage due to high temperature
variations in the heating system.
▶ If the boiler is operated in connection with a
refrigeration system, make sure that the pipes for the
refrigerated liquid are connected in parallel to the
boiler system with suitable valves to prevent the
refrigerated liquid from entering the boiler.
▶ The piping system of a boiler connected to the heating
coils of hydro-air heating systems that may be
exposed to the circulation of cooled air must be
equipped with a flow-control valve or some other
automatic system for preventing the boiler water from
circulating by gravity during the cooling cycle.
