7. Back Flow Preventer : A back flow preventer (check valve)
is required by some jurisdictions to prevent water in the
hydronic system from backing up into the city water supply.
This is especially important on systems in which glycol
solution is used as the heating medium.
8. Pressure Relief Valve : The boiler pressure relief valve is
shipped separately for field installation. The valve is to be
installed as shown in Figures 4.2 or 4.3. Pipe the discharge
of the relief valve to within 12" of the floor and close to a
floor drain. Provide piping that is the same size or larger
than the relief valve outlet.
WATER PIPING AND CONTROLS
9. Low Water Cut Off : When installing a probe type LWCO,
locate the LWCO in the boiler supply above the top jacket
panel. Refer to Section 7. Electrical Connection in this
manual for wiring details.
10. Circulator : The Central Heat circulator is to be sized to
overcome the pressure drop of the system while providing
the flow required by the boiler. The Peak boilers have a
built in circulator that guarantees the minimum flow rate is
maintained through the unit.

WARNING
CAUTION
Do not operate this appliance without installing the
pressure relief valve supplied with the boiler or one
with sufficient relieving capacity in accordance with
the ASME Rating Plate on the boiler heat exchanger.
Pipe the discharge of the relief valve as close as
possible to the floor and away from high traffic areas.
Pipe the discharge to a floor drain. Failure to do so
may result in personal injury and/or property damage.
