Lubricate During Assembly
When assembling the Exhaust and Air-Inlet piping, apply Centrocerin (a water based lubricant) to each gasket and
male end, to ease the assembly process, and to prevent gasket damage.
Failure to apply Centrocerin lubricant to each connection may cause the gasket to be
damaged or dislodged during assembly, resulting in property damage, personal injury or
death.
The CHS 300-399 Common Venting and the first 5 feet of the common vent shall not be
enclosed or covered and must be easily accessible for maintenance and inspection; failure
to do so may lead to property damage.
Exhaust Vent Slope
The Exhaust Manifold must slope back towards the boilers a minimum of 3/8” per linear foot; the Exhaust
Appliance Adapters and the Exhaust Supports have been pre-sized to achieve the required slope, see Step 8 of
this section.
Failure to assemble the CHS 300-399 Common Venting in the correct order may result in
property damage, personal injury or death.
Connector Rings
Connector Rings are mandatory on every connection, with the exception of the Exhaust and Air-Inlet connection
at the boilers, which are secured with a gear clamp. The Connector Rings are mandatory and prevent the pipe
connections from coming apart. See Figure 4-4 for Connector Ring Installation Instructions.
Figure 4-4 Connector Ring Installation Instructions
Failure to properly install Connector Rings on every connection may result in property
damage, serious injury or death.
Assemble the CHS 300-399 Common Venting, including the Exhaust and Air-Inlet
Supports, as shown in this section. The instructions and illustrations in this section
