Dunkirk Q95M-200 Installation, Operation & Maintanance Manual page 21

Antifreeze solutions can breakdown over time. Failure to
check antifreeze chemistry, including inhibitors, annually
may result in accelerated corrosion of boiler and other
system components. Consult with the antifreeze manufac-
turer for recommendations.
• Use of antifreeze in any boiler will reduce heating capacity
as much as 10-20%. This must be taken into consideration
when sizing the heating system, pumps and expansion
tank. Consult antifreeze manufacturer's literature for spe-
cific information on reduced capacity.

* These products may be used to adjust the pH level of the hydronic system, but on occasion may not resolve the pH issue. In these cases it is recommended
to flush the system and refill with untreated water and new boiler manufacturer approved antifreeze suitable for Aluminum heat exchangers.
IMPORTANT
: Regardless of antifreeze or inhibitors used, be sure to follow the antifreeze manufacturer's instructions for use, safe handling and storage of
their products. Refer to the MSDS (Material Safety Data Sheets) provided by the antifreeze manufacturer for potential hazards and first aid procedures for
exposure or ingestion.
Antifreeze Testing Services:
and contractor. Contact the antifreeze manufacturer regarding their sampling plan procedure. Consult the antifreeze manufacturer for details on sample
requirements and recommendations.
The boiler manufacturer reserves the right to make changes without notice.

NOTICE
Each of the recommended antifreeze manufacturers have developed a sampling program available to the homeowner
• Using the antifreeze manufacturer's instructions to deter-
mine the freezing temperature needed and use the correct
amount of antifreeze. Never exceed 50% antifreeze by
volume.
• The boiler operating pressure must remain below 15 psi
for antifreeze solutions that specify a maximum of 250˚F
(121˚C).
