Venting

WARNING

The vent system must be installed properly. Failure to properly install the vent system could result in property damage, personal injury, or death.

This water heater has been shipped with a draft diverter for which it was designed with reference to the horizontal and vertical planes. If removed, the draft diverter shall be replaced in the same position and secured to the jacket top by the screws with which it was installed.

This water heater must be connected to a masonry chimney or venting system approved by local codes or ordinances. The vent connector used to attach the draft diverter outlet to the chimney or approved vent must be of the same diameter as the draft diverter outlet or larger. For proper venting in certain installations, a larger vent connector may be needed. Consult venting tables in ANSI standard (Z223.1-or latest edition), National Fuel Gas Code and CAN/CGA (B149.1 or B149.2-latest editions), or local code officials for proper application for your area.

Flue Damper

Refer to Figure 5 and follow these instructions:

CAUTION

Do not turn on electrical power to water heater until flue damper is installed and water heater is filled with water.

1.Remove the damper from the accompanying box shipped within the crate.

2.Locate the collector outlet on top of the water heater. Place the damper over the collector outlet and rotate as necessary to a position in which the damper wiring plug can be fully engaged with the connector on the side of the water heater.

3.Remove clip which holds damper vane closed. If supplied this type of vent damper will then open by itself.

4.Being certain that the damper vane will travel freely from the “closed” to “open” position, secure the flue damper to the jacket top with sheet metal screws. Note: Some dampers require an additional bracket to assure level installation.
