applicable national and local codes.

The water heater must be vented in accordance with the section "Venting of Equipment" of the current

edition of the National Fuel Gas Code: ANSI Z223.1/NFPA 54 in the United States and/or Section 7 of the

CAN/CSA B149.1 Natural Gas, propane installation code in Canada, as well as applicable local building codes.

The water heater is designed for a concentric venting system, which uses one pipe system with two

ducts for combustion air and exhaust air. The manufacturer approves the use of Centrotherm Eco

Systems Direct Vent APNC35 venting systems on new installations. This system is furnished through

the heater manufacturer. See the table below for certified vent terminations.

General rules for venting water heaters:

• Place the water heater as close as possible to the vent termination.

• Do not weld the vent pipe to the water heater's vent collar.

• Do not cut the vent collar of the unit.

• The vent must be easily removable from the top of the water heater for normal service and

inspection of the unit and vent system.

• The water heater vent must not be connected to any other gas appliance or vent stack.

• Avoid using an oversized vent pipe or using extremely long runs of the pipe.

• Do not common vent or connect any vent from other appliances to the water heater vent.

• The vent should slope towards the heater and condensate collector (100266139).

condensate trap (100266140) must be installed below the condensate collector's drain nipple to

keep condensate from draining back into the heater's exhaust and causing damage. Condensate

is corrosive and should be treated and disposed of according to local codes.

General rules for vent terminations:

• Avoid locating the water heater vent termination near any air intake devices. These fans can

pick up the exhaust flue products from the water heater and return them to the building. This

can create a health hazard.

• Locate the vent termination so that it cannot be blocked by any debris, at any time. Most codes

require that the termination must be at least 12 in. (305 mm) above grade and anticipated snow

line, but the installer may determine if it should be higher depending on the job site condition

and applicable codes.

• A proper sidewall termination is recommended when the water heater is vented through a

sidewall.

• Regarding the clearances from the exhaust termination to the air inlet or opening, refer to

p 11, 16, and 17.
