HRV200PLUS INSTALLATION INSTRUCTIONS
D. DEFROST OPTIONS
The HRV200PLUS performs as a whole house heat recovery ventilator during Fresh Air Fireplace operation and continuous ventilation
operation. When the Fresh Air Fireplace is in use, the HRV core temperature is elevated with no chance of frost or ice build-up at any
time. However, when the HRV200PLUS is operating in continuous ventilation mode, outdoor temperatures below 25°F can cause frost
to form on the core. This frost can reduce airflow through the HRV resulting in unbalanced operation and could inhibit Fresh Air
Fireplace operation.

6100 PLUS are shipped with fixed mesh screens to provide a barrier between the occupants and the fire.
