HI-EFFICIENCY HEATING
A HOT AIR GRAVITY VENT SYSTEM (NZ221) may be
used to distribute heat to an adjoining room (located either above, or beside the room containing the fireplace) by way of vents. Air flow through this vent must be experimented with and the dampers of the grill adjusted manually to suit your requirements. This may take a few attempts; thereafter ad- justments should no longer be required as is normally expe- rienced with your central heating system registers.
The hot air vent must be installed in an upward direction! NEVER install in a downward direction. The hot air gravity vent system is not to be connected to a central heating system.
No more than two hot air gravity vents may be connected to the fireplace. Individual vent runs are not to exceed 10 feet.
All hot air gravity vents must be insulated.
