Installation Instructions
PLANNING FOR VENTING
INTAKE/EXHAUST GUIDELINES
Refer to the specific instructions on your vent
product for additional installation requirements.
• 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. See
approved venting list on page 20.
• Do not combine vent components from different
manufacturers.
• The vent system must vent directly to
the outside of the building and use outside
air for combustion.
• Every vent connection must be accessible for
inspection, cleaning and replacement.
• Avoid dips or sags in horizontal vent runs by
installing supports per the vent manufacturer’s
instructions.
• Support horizontal vent runs every four feet
and all vertical vent runs every six feet or in
accordance with local codes.
• Venting should be as direct as possible with
a minimum number of pipe fittings.
• Vent diameter must not be reduced.
• Do not connect the venting system with
an existing vent or chimney.
• Do not connect vent with the vent pipe of any other
water heater or appliance.
• 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.
• Refer to the vent pipe manufacturer’s instructions
for component assembly instructions.
• It is recommended to install an optional inlet screen
to minimize blockage and maintenance from debris.
