Risk of carbon monoxide poisoning if adapter is improperly attached. Mechanical connections (such as screws) can cause
cracking and leaks in the adapter. Do NOT drill holes or use screws to connect the appliance adapter to the heater vent body.
Attach with manufacturer's specified adhesive.
Risk of fire or asphyxiation if vent is not assembled according to manufacturer's instructions or if vent parts from different
manufacturers are mixed. Vent parts from different manufacturers ARE NOT interchangeable. Mixing parts from more than one
manufacturer may cause leaks or damage to vent. When installing a vent, pick one manufacturer and be sure that all vent parts
come from that manufacturer and are specified by the manufacturer for your system. Follow manufacturer's instructions and
local and National Fuel Gas Code (U.S.) or CSA B149.1, Natural Gas and Propane Installation Codes (Canada) requirements
carefully during assembly and installation.
