Step 1: Thoroughly read and understand the venting section of the Installation and Operating Instruction Manual that
was supplied with the water heater before determining the location of the water heater and the vent terminals. Locate
the water heater for the shortest practical vent length to the outside. Measure the total venting distance required to
reach the outside wall or roof. Determine the diameter of the venting components to use for the length of vent pipe
(and combustion air supply for direct vent models) required by referring to the venting tables in the instruction manual
for the maximum vent length for each diameter pipe size. Obtain all the necessary venting system components for the
installation.
Step 2: Before installation, inspect each vent component for damage making sure the gaskets for each component are
fully intact and in undamaged condition. Do not attempt to install or repair damaged components. If a gasket is
damaged, these are available from the supplier of Centrotherm Innoflue components. Do not use gaskets from another
manufacturer and do not try to repair the gasket.
Step 3: A Centrotherm PVC to Polypropylene adapter (Centrotherm ISAGL part series) must be used to connect into a
PVC coupling or tee (Commercial and Residential Power Direct Vent air intake connections), condensate elbow (High
Efficiency Commercial Condensing models) or the exhaust outlet adapter for Commercial Power Direct Vent and
Residential Power Vented models. To make the insertion of the gasketed fittings into the coupling easier, Centrocerin
gasket lubricant is recommended. Centrocerin is a water based lubricant available from your Centrotherm supplier. If
Centrocerin is not available, water may be used. DO NOT use any other kind of lubricant which may damage the
gaskets.
Apply lubricant using your finger to the gasket surface and inside of the coupling and insert the male end of the adapter
with the exterior gasket into the coupling, condensate elbow or exhaust outlet adapter connection. If a larger vent
diameter size is to be used, use the appropriately sized reducer coupling first on the water heater intake or exhaust vent
connection as detailed in the installation manual supplied with the water heater. See the following photos.
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.
High Efficiency Condensing Commercial Models: Use the appropriate primer and cement (refer to venting section of
instruction manual with water heater) for cementing a PVC coupling (not supplied with water heater) to the end of the
PVC air intake pipe connection. Apply Centrocerin lubricant with your finger to the male gasketed end of the
Centrotherm PVC adapter and fully insert into the air intake coupling. Loosen the Centrotherm flue pipe clamp
(Centrotherm p/n IAFC03) and install on the end of the PVC coupling so that the 3 clamp hooks secure the PVC adapter
to the PVC coupling. See following photos.
