The Condensing Gas Combi Boiler discharges condensate.
When heat from the exhaust gas is collected within the secondary heat
exchanger, condensation occurs from moisture in the exhaust gas and
the resulting water is discharged from the drain pipe (approx. 2 gallons/
hour (7.5 liters/hour) maximum).
It is not a water leak. Do not plug or block the drain line as it must always
be allowed to freely ow.
Note: The condensate discharged is acidic with a pH level of
approximately 2-3. A condensate neutralizer may be required by local
code prior to disposal.

PRODUCTS TO AVOID AREAS LIKELY TO HAVE CONTAMINANTS
Spray cans containing uorocarbons Dry cleaning/laundry areas and establishments
Permanent wave solutions Swimming pools
Chlorinated waxes/cleaners Metal fabrication plants
Chlorine-based swimming pool chemicals Beauty shops
Calcium chloride used for thawing Refrigeration repair shops

Do not operate the Combi Boiler if its combustion air intake is located in or near one of the areas or in the vicinity of products listed in
Table. 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 Combi Boiler’s heat exchanger, burner components and vent system, resulting in ue gas spillage
and/or water leakage, possible substantial property damage, severe personal injury, or death. If the Combi Boiler 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.
