CARBON MONOXIDE POISONING, FIRE AND EXPLO- SION HAZARD

Failure to properly vent this furnace can result in

death, personal injury and/or property damage.

Inlet and outlet pipes may NOT be vented directly

above each other (standard vent terminals).

4.The vent termination shall be located at least 4'horizontally from any electric meter, gas meter, gas regulator, and any

relief equipment. These distances apply ONLY to U.S. installations.

5.The vent termination is to be located at least 3' above any forced air inlet located within 10' ; and at least 10' from a

combustion air intake of another appliance, except another direct vent furnace intake.

6.In Canada, the Canadian Fuel Gas Code takes prece- dence over the preceding termination instructions.

Concentric Vent Termination - Kit #

1.Determine termination locations based on clearances spe-

cified in following steps and as shown in Figure 7, Figure 44 through Figure 49.

2.The vent termination must be located at least 12" above

ground or normally expected snow accumulation levels.

3.Do NOT terminate over public walkways. Avoid areas

where condensate may cause problems such as above planters, patios, or adjacent to windows where steam may cause fogging.

NAHA001CV & NAHA002CV

These kits are for vertical or horizontal termination of the combus- tion air inlet and the exhaust vent pipes on Category IV gas-fired condensing furnaces. The NAHAO01CV kit can be used for 3" di- ameter pipe systems. The NAHAOO2CV kit can be used for 2" diameter pipe system. Refer to Table 10 for the correct pipe size for the furnace. Both the combustion air inlet and the exhaust vent pipes must attach to the termination kit. The termination kit must

terminate outside the structure and must be installed per the instructions outlined below for vertical or horizontal termination.
