NOTE 2
For high wind, wind blocked sites, a tee may be installed at the fresh air inlet. The leg of the
tee connects to the combustion air intake. The branches of the tee can be in the horizontal or
vertical direction, as determined by the system designer and site conditions.
IMPORTANT NOTES:
1. Please consult the AERCO factory for all applications utilizing common ducted combustion
air with common breeching of exhausts.
2. AERCO boilers and AERCO water heaters may share common combustion air and
exhaust breeching. Other configurations, not depicted in this guide, are possible. If you
intend to implement any of these options, please contact your local AERCO representative
or the AERCO factory for project specific venting and combustion air configurations.
