allow drainage of condensate. When placing support brackets on vent piping, the first bracket must be within 1 foot (30 cm) of the appliance and
the balance at 4 foot (1.22 m) intervals on the vent pipe. Appliance venting must be readily accessible for visual inspection for the first three feet
from the appliance.

Screens can freeze in areas with severe cold weather. In such areas it is recommended not to use screens.
