Thank you for your question on the ERV90HCS and the TYIK1 tandem transition kit. The ERV90HCS does not come with the outdoor hood. The TYIK1 tandem transition kit is used if you want only one penetration through the wall. This kit does come with the exterior hood. If you have further questions, please contact Technical Support at 800-637-1453. Thank you.
