Water Quality Conrm the water quality. Refer to secon “4.4.1 Water Quality Guidelines” to
determine if the water needs to be treated or condioned. DHW must be
potable, free of corrosive chemicals, sand, dirt, or other contaminates. It is up to
the installer to ensure the water does not contain corrosive chemicals or
elements that can aect or damage the heat exchanger. Water that contains
chemicals exceeding the levels required aect and damage the heat exchanger.
Replacement of the heat exchanger due to water quality damage is not covered
by the warranty.
Snow
Accumulaon
• Verify the area around the ue terminal is free of snow and ice. The boiler will
not funcon properly if the combuson air or exhaust vent pipes are impeded
(blocked or parally blocked) by obstrucons.
• Verify the condensate drain line is free of snow and ice. Ensure the line is not
blocked or clogged and that condensate is owing freely.
Freeze
Protecon
• Freeze protecon for new or exisng systems must use glycol that is specially
formulated for this purpose. This includes inhibitors, which prevent the glycol
from aacking the metallic components. The glycol should be for mul-
metallic components. Reference secon “14.1 Approved Cleaners, Inhibitors
and Anfreezes” in the Appendix for an approved list of system cleaners,
inhibitors, and anfreezes.
• Check that the system uid is correct for the glycol concentraon and inhibitor
level. The system should be tested at least once a year and as recommended
by the producer of the glycol soluon. The allowed maximum concentraon is
40 percent.
Coast Area
Installaons
Installaons located in or near coastal areas may require addional maintenance
due to corrosive airborne ocean salt. If corrosion is observed on the body of the
boiler, the boiler shall be inspected to ensure proper operaon and repaired or
replaced, if necessary.
Cleaning It is imperave that control compartments, burners, and circulang air
passageways of the boiler be kept clean. Check burner ame for proper color.
Once ignited, the ame must cover the surface of the burner. The ame must
burn with a clear, blue, stable ame. If the ame does not have this appearance,
complete the following steps:
• Turn o and disconnect electrical power. Allow to cool.
• Remove the front panel.
• Use a vacuum to remove dust from the main burner and fan blades. Do not
use a wet cloth or spray cleaners on the burner. Do not use volale
substances such as benzene and thinners; they may ignite or fade the paint.
• Do not open the burner cabinet and touch the burner surface.
Condensate Trap Cleaning:
• Inspect the condensate drain assembly inside the boiler and your external
drain system.
• Remove any debris that may be present in the condensate removal system.
