Thank you for your question on the model HRVH100SE heat recovery ventilator. The preferred method is to install the fresh air intake and outside exhaust in a wall orientation in accordance with your instruction manual's requirements. This orientation provides the owner with the easiest accessibility to perform route maintenance and inspection. However, if the building's construction does not allow wall installation, both the intake and exhaust vents may be roof mounted. The owner must insure the proper separation distances are maintained as well as the distance from any combustion exhaust and waste vent exhaust as outlined in the owner's service manual. Please note, routine cleaning and inspection will still need to be performed. Please contact technical support at 800-637-1453 for further assistance.
