i- Unit ampacity = 125 percent of largest operating component's full load amps plus 100 percent of all other potential operating components' (EAC, humidifier, etc ) full
load amps
$ Length shown is a measured 1 way along wire path between unit and service panel for maximum 2 percent voltage drop
** Time-delay type is recommended
_lrnace casing in vertical pipe. (See Fig 320 This allows proper
drainage of vent condensate
Combustionoair and vent pipes must terminate together in same
atmospheric pressure zone, either through roof or sidewall (roof
termination preferred), using accessoI 7 termination kit.
See Table 5 tbr required clearances.
Furnace combustion-air and xent pipe connections must be at-
tached as shown in Fig. 33. Combustion-air intake plug fitdng and
inducer housing alternate _ent cap may need to be relocated in
some applications.
NOTE: Slope combustionoair and xent pipes down\\ared toward
furnace a minimum of 14 in per linear ft with no sags between
hangers.
