WARNING
The venting system must be properly installed. Failure to properly install the vent system could result in property
damage, personal injury, or death.
DO NOT install damaged venting system components. If damage is evident then please contact the supplier where
the water heater or venting system components were purchased for replacement parts.
Use only the vent terminals provided or factory authorized terminals for venting this water heater.
The water heater requires its own separate venting system. Do not connect the exhaust vent into an existing vent pipe
or chimney.
All of the exhaust venting connections must be leak checked with a soap solution upon initial start-up of the water
heater. Any leaks must be repaired before continuing operation of the water heater.
Do not terminate the venting where noise from the exhaust or intake will be objectionable. This includes locations
close to or across from windows and doors. Avoid anchoring the vent and intake pipes directly to framed walls, floors,
or ceilings unless rubber isolation pipe hangers are used. This prevents any vibrations from being transmitted into the
living spaces.
Do not exceed the venting distances or the number of elbows listed in the instruction manual supplied with the water
heater. Exceeding the maximum venting distances may cause the water heater to malfunction or cause an unsafe
condition.
DO NOT operate this water heater until the venting installation is complete and the piping completed. Failure to
complete installation before operation can result in property damage, personal injury, or death.
DO NOT install Centrotherm Innoflue venting components with any other manufacturer’s vent components.
Centrotherm Innoflue components must be used exclusively throughout the entire venting system from the water
heater coupling or vent connection to the outside wall or ceiling near the vent terminal location.
This supplement is intended only for additional information for installing Centrotherm Innoflue single wall venting
system and the instruction manual supplied with the water heater must be followed for the detailed information
provided for the venting system installation.

WARNING
Use only water or Centrocerin lubricant for lubricating the gaskets and pipe ends to allow easy insertion. DO NOT
use any other kind of lubricant, since deterioration of the gasket may result, which may allow dangerous flue gases
to leak into the room. If the vent pipe needs to be disassembled after the gasket has dried, wet the joint thoroughly
to loosen the connection.
