Vertical concentric fl ue system in cold climates
In cold climate conditions where temperatures go below 14°F (-10°C ), we
recommend that the chase be insulated and where the concentric fl ue pipe enters
into the attic space that the pipe be wrapped with a non-combustible insulation
sleeve. This will increase the temperature of the pipe and help the appliance to
vent properly in cold weather conditions.
It is also important that appliances with a vertical concentric fl ue system, be
operated daily during the winter months. This will help to stop the roof termination
from freezing up. We recommend using the thermostat room temperature setting
on the remote to allow the appliance to cycle.
IMPORTANT : Always keep the Pilot in the ON position (burning) when the
outside temperature is below freezing.
IMPORTANT : Do not use Silicone/RTF products, as they will create a white
residue on the glass! When necessary, use an alternative direct vent sealing
compound. (for example Mill-Pac Sealant)
There are two basic types of direct-vent installation:
- Horizontal termination
- Vertical termination
The combined fl ue gas channel and combustion air intake requires one of concentric
fl ue system confi gurations as depicted in fi gures 7 to 12.
