B. Primary Water
• Do not attempt to clean the heating system. Call a qualified
service technician for service.
• If you notice any leaks, immediately call a qualified service
technician. Leaks in appliance or piping must be repaired at
once.
Closed loops that use glycol as heat transfer fluid must be serviced
periodically. Glycol can break down over time, become acidic, and
attack gaskets and seals in appliances. This can result in property
damage, severe personal injury, or death.
Each glycol manufacturer has different recommendations for
testing and replacement. Do not test glycol quality yourself. Have
your qualified service technician check glycol quality during annual
servicing. If you are unsure when your glycol was last tested, call a
qualified service technician to test and replace glycol, if necessary.
C. Freeze Protection Fluids
Part 2 - Combustion Air Contamination Prevention
Do not operate the appliance if its combustion air intake is located in
or near one of the areas or in the vicinity of products listed in Table
1. These areas will always contain hazardous contaminates that
can form strong acids while passing through the burner and vent
system. These acids will corrode the appliance’s heat exchanger,
burner components and vent system, resulting in flue gas spillage
and/or water leakage, possible substantial property damage, severe
personal injury, or death. If the appliance combustion air intake is
located in any area likely to cause or contain contamination, or if
products which would contaminate the air cannot be removed, the
intake must be re-piped and terminated to another location.
DO NOT
re-pipe ventilation system on your own. Call a qualified
service provider for assistance.
