INSTALLATION INSTRUCTIONS

Flue Installation with Centrotherm Venting

Install the venting termination according to the diagrams and in-
structions below.
• Comply with the exhaust clearances found in the Giant Installa-
tion and Operating Manual.
• Only one appliance can be attached to the vent system.
• Install the system according to the Centrotherm installation in-
structions.
Tuyau d'air de combustion
• Use the 3"/5" (7.6/12.7 cm) concentric to twin pipe adaptor and
the 3-inch (7.6 cm) diameter venting.
• The vent termination and air intake must be in the same pressure
zone.
• Do not exceed maximum straight vent length with number of
elbows as shown in the following tables.
• Maintain the clearances shown in the following Figures.

Condensate

prévu de neige
Condensate formation can occur in high efficiency direct vent
appliances. Without proper drainage condensate will damage the
heat exchanger.
To prevent condensate damage, follow these instructions.

• Do not connect the condensate drain line with an air condition-
ing evaporator coil drain.
MUST DO
• Use only vent that is approved and identified as acceptable for
your particular model.
• Slope the venting toward the appliance according to the vent
manufacturer's installation instructions.
• All condensate must drain and be disposed of according to local
codes.
• Use only corrosion resistant materials for the condensate drain
lines, such as PVC pipe or plastic hose.

• The condensate drain pipe (along its entire length) must be at
least the same diameter as the drain line, (1/2 inch NPT).
• The end of the condensate drain pipe should be open to the at-
mosphere. The end should not be under water or other sub-
stances.
