Installation of venting

Install the correct venting for your model according to the venting
manufacturer’s instruction and the guidelines below (

see Table 7

and Table 8

). Refer to the manufacturer’s technical literature for

specific part numbers and instructions.

Venting Guidelines

DO NOT

• Do not use cellular core PVC/CPVC, Radel, or galvanized materi-

al to vent this appliance.

• Do not combine vent components from different manufacturers.
• Vent diameter must not be reduced.
• Do not connect the venting system with an existing vent or

chimney.

• Do not common vent with the vent pipe of any other manufac-

turer’s water heater or appliance. Giant water heaters can only
be common vented using a Giant certified common vent sys-
tem. Common venting is approved for Canadian and U.S. instal-
lations.

MUST DO

• This water heater is a direct vent water heater and therefore is

certified and listed with the vent system. You must use vent
components that are certified and listed with the water heater
model.

• The vent system must vent directly to the outside of the building

and use outside air for combustion.

• Avoid dips or sags in horizontal vent runs by installing supports

per the vent manufacturer’s instructions.

• Support horizontal vent runs every four (4) feet (1.2 m) and all

vertical vents run every six (6) feet (1.8 m) or in accordance with
local codes.

• Venting should be as direct as possible with a minimum number

of pipe fittings.

• Vent connections must be firmly pressed together so that the

gaskets form an air tight seal.

• The vent piece connected to the water heater must be secured

with one self-tapping screw.

INFORMATION

• Refer to the instructions of the vent system manufacturer for

component assembly instructions.

• If the vent system is to be enclosed, it is suggested that the de-

sign of the enclosure shall permit inspection of the vent system.
The design of such enclosure shall be deemed acceptable by the
installer or the local inspector.

If it becomes necessary to access an enclosed vent system for
service or repairs, Giant is not responsible for any costs or
difficulties in accessing such vent system. The warranty does
not cover obtaining access to a vent system in an enclosed
environment.
