CARBON MONOXIDE POISONING, FIRE AND EXPLOSION HAZARD

Failure to properly vent this furnace could result in death, personal injury and/or property damage.

Inlet and outlet pipes may NOT be vented directly above each other (standard vent terminals).

1.Determine termination locations based on clearances spe-

cified in following steps and as shown in Figure 7, Figure 45 through Figure 50.

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.

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.

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 Codetakes precedence

over the preceding termination instructions.

Concentric Vent Termination - Kit #

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" di- ameter pipe system. Refer to Table 13 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 in- structions outlined below for vertical or horizontal termination. Ver-
