IMPORTANT NOTES
: 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.
6.4 Suggested Piping Schematics
Figures 13 through 19
show suggested piping
configurations for Mascot II boilers. These diagrams are
only meant as a guide. All components or piping
required by local code must be installed.
6.5 Recognized Chemicals
The following manufacturers offer glycols,
inhibitors, and anti-foamants that are suitable for use in
the Mascot II. Please refer to the manufacturers
instructions for proper selection and application.
1. Sentinel Performance Solutions Group
2. Hercules Chemical Company
3. Dow Chemical Company
6.6 Hot Water Piping
6.6.1 Domestic Hot Water Piping (LMC)
Connect domestic hot and cold water piping to the
boiler at locations noted in
Figure 3
. Expected DHW
performance is indicated in
Table 8
.
Use of flow restrictor is optional to prevent colder
water at excessive flow rates. Contact Laars for alternate
configurations.
6.6.2 Indirect Water Heater Piping (LMH)
The LMH model can control an indirect water
heater zone. Pipe to the locations shown in
Figure 3
.
Zone valve and associated wiring are not required.
Setpoint is made via aquastat located on the indirect
water heater, or can be controlled at the boiler via a
remote sensor.
