Vertical Stack is the ideal multi-room solution when a ceiling-mounted unit is not desired or feasible. The compact 30cm by 64cm footprint uses minimal floor space. This unit is perfect anywhere direct venting or ducting is required with up to 150 ESP PA external static pressure. Use any style grilles and louvers for maximum design flexibility.
A unique feature of the Innova Vertical Stack unit is that it can be installed on a corridor wall, enabling it to be fully serviced without entering the apartment or hotel room. A bathroom exhaust can connect to the dedicated stale air exhaust - which can be field modified to left or right. The Vertical Stack unit is available with or without the integrated ERV and can be vented directly outside or through ductwork
Airflow
INNOVA Vertical Stack is extraordinarily flexible in the many ways it can be fully ducted or used with minimal or no ducting. This flexibility enables Vertical Stack to be placed anywhere in a dwelling with no restrictions.
Supply Air
The front rectangular 170 mm × 457 mm supply air connection is ideal for a supply grille. With 150 Pa external static pressure (combined between return and supply), the top rectangular 170 mm × 457 mm supply air connection is ideal for ducting to one or more rooms.
For added flexibility, duct part through the top and direct‑vent part through the front for supplying multiple rooms with minimal ductwork.
Stale Air Exhaust
The 125 mm round stale air exhaust connection can be used as part of a plenum return without any ducting, or it can be ducted to a bathroom or multiple locations with up to 125 Pa ESP. This connection can be field‑swapped from left to right.
Return Air
The left and right side 150 mm round connections can be ducted to one or more rooms with up to 150 Pa external static pressure (combined between return and supply).
They can also be left open as side plenum returns. Each connection is fully independent, with two ECM fans, each with auto ESP. You can duct both, leave both open, or duct one and leave one open to a plenum.
Outside Air Intake
The single 200 mm round outside air intake connection can be accessed from the left, right, or rear, and provides outside air for the condenser portion and fresh air.
This can be ducted with up to 175 Pa ESP (combined between intake and exhaust).
Outside Air Exhaust
The single 200 mm round exhaust air connection can be accessed from the left, right, or rear, and exhausts the stale and condenser air.
This can be ducted with up to 175 Pa ESP (combined between intake and exhaust).
Mix and match outside connections for total flexibility
The upper outside connection (left, right, and rear) is for exhaust, and the outside lower connection (left, right, and rear) is for supply. It’s possible to use any combination of connections. For example: Left for intake and rear for exhaust, or rear for intake, and right for exhaust, etc.
