All vent pipes must be glued, properly supported, and the exhaust must be pitched a minimum of ¼" per foot back to the appliance to

allow drainage of condensate. When placing support brackets on vent piping, the first bracket must be within 1 foot of the appliance and

the balance at 4 foot intervals on the vent pipe. Appliance venting must be readily accessible for visual inspection for the first three feet

from the appliance.

After connecting the intake air and exhaust vent pipes, it is required to install the included screens into the exhaust vent and intake pipe

terminations to prevent damages to the unit due to blockages. See Figure 12 for installation detail.
