Different glycol products may provide varying
degrees of protection. Glycol products must
be maintained properly in a heating system, or
they may become ineffective. Consult the glycol
specifications, or the glycol manufacturer, for
information about specific products, maintenance
of solutions, and set up according to your particular
conditions.
The following manufacturers offer glycols,
inhibitors, and anti foamants that are suitable
for use in the MagnaTherm. Please refer to the
manufacturers instructions for proper selection and
application.
• Sentinel Performance Solutions Group
• Hercules Chemical Company
• Dow Chemical Company
The boiler control offers some assistance with freeze
protection, as long as the boiler is energized, and
able to fire.
1. If the outlet sensor detects less than 45
°F, the
control energizes the boiler pump.
2. If the outlet sensor detects less than 35
°F, the
control will fire at low rate.
3. Once in freeze protect mode, the boiler will
remain in that state until the outlet sensor detects
greater than 50
°F.
6.4 MGH Suggested Piping Schematics
Figure 7 through Figure 10 show suggested piping
configurations for MGH boilers. These diagrams
are only meant as guides. All components or piping
required by local code must be installed.
6.5 Condensate Drain Trap
A condensate drain trap is included with the
MagnaTherm and is designed to drain the boiler of
condensate. The vent condensate should be drained
through a drain tee located in the vent line. This will
help prevent excessive condensate from entering the
boiler condensate trap.
Connect a 3/4” PVC pipe between the drain
connection and a floor drain (or condensate pump if
a floor drain is not accessible).
The condensate drain must be installed to prevent
the accumulation of condensate. When a condensate
pump is not used, the tubing must continuously
slope downward toward the drain with no spiraling.
Consult local codes for the disposal method.
Caution
Condensate is mildly acidic (pH=5), and
may harm some floor drains and/or pipes,
particularly those that are metal. Ensure
that the drain, drainpipe, and anything that
will come in contact with the condensate
can withstand the acidity, or neutralize
the condensate before disposal. Damage
caused by failure to install a neutralizer
kit or to adequately treat condensate will
not be the manufacturer’s responsibility.
