Vent Pipe System

This water heater uses a non-direct, single-pipe vent

system to remove exhaust gases created by the burning of

fossil fuels. Air for combustion is taken from the immediate

water heater location or is ducted in from the outside (see

“Combustion Air Supply and Ventilation” section).

This water heater must be properly vented for the removal

of exhaust gases to the outside atmosphere. Correct

installation of the vent pipe system is mandatory for the

proper and efficient operation of this water heater and is

an important factor in the life of the unit.

The vent pipe must be installed according to all local and

state codes or, in the absence of local and state codes, the

“National Fuel Gas Code”, ANSI Z223.1(NFPA 54)-current

edition. The vent pipe installation must not be obstructed

so as to prevent the removal of exhaust gases to the

outside atmosphere.

IMPORTANT: The use of vent dampers is not

recommended by the manufacturer of this water heater.

Although some vent dampers are certified by CSA

International, this certification applies to the vent damper

device only and does not mean they are certified for use

on this water heater.

U.L. recognized fuel gas and carbon monoxide (CO)

detectors are recommended in all applications and should

be installed using the manufacturer’s instructions and local

codes, rules, or regulations.

IMPORTANT: If you lack the necessary skills required

to properly install this venting system, you should not

proceed, but get help from a qualified technician.
