5.3 inStalling tHe DuctWoRk anD tHe RegiSteRS
⚠WARNING
• Never install a stale air exhaust register in a closed room where a combustion device operates, such as a gas
furnace, a gas water heater or a fireplace.
• When performing duct connections, always use approved tools and materials. Respect all corresponding laws
and safety regulations. Please refer to your local building code.
If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts to prevent condensation
formation inside and outside ducts, which could cause material damage and/or mold growth. Moreover, if fresh
air to building duct and/or stale air from building duct goes/go through an unconditioned space, the unit must
be set to operate continuously in cold conditions (below 10°C/50°F). Continuous air movement inside ducts will
prevent condensation formation. The unit can be stopped temporarily for maintenance and/or repair purposes in
such conditions.
