FLOW PROVING DEVICE (wall mount
models and combination models only)
Figure 20: Flow Proving Device
The flow proving device is designed to detect when flow is
present. This is done by detecting the amount of current
(amperes) that exists in the live wire to the pump. When the
current becomes too low a LCI error is displayed indicating a
lack of water inside the boiler. The flow proving device is
provided on all DynaMax HS wall mount models (DM 200
–
250) and combination floor model units (213
– 803). This
switch is factory wired.

WATER FLOW SWITCH (Floor mount
hydronic and DHW models only)
A paddle style water flow switch is shipped loose and is to be
installed in the outlet piping on all floor model heating boilers
(DM 211-801) and hot water supply heaters (DM 212
– 802).
The flow switch is to be installed in a horizontal run of pipe in
order to provide effective contact. The flow switch is to be
wired into the DynaMax HS
terminal board labelled ‘Flow
Switch
’.

LOW WATER CUTOFF (If Equipped)
If this boiler is installed above radiation level, a low water cut-
off device must be installed at the time of boiler installation.
Some local codes require the installation of a low water cut-
off on all systems. Electronic low water cut-offs are available
as a factory supplied option on all models. Low water cut-offs
