Elbows are DWV Long Radius Type for 2" and 3" vents.
If more than five elbows are required, reduce the length of
both the inlet and exhaust pipes 5' for each additional elbow
used.

VentTermination Clearances
Poison carbon monoxide gas, fire and explo-
sion hazard.
Inlet and outlet pipes may NOT be vented
directly above each other.
Failure to properly vent this furnace can result in
death, personal injury and/or property damage.
1. Determinetermination locations based on clearances spe-
cified in following steps and as shown in Figure 7,
Figure 17, through Figure 25.
For "Concentric Termination Kit" clearances, see Figure 43,
Figure 44, Figure 45, Figure 46and Figure 47 in "Section 10"
in this manual.
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 venttermination shall be located at least 4' horizontally
from any electric meter, gas meter, regulator, and any relief
equipment. These distances apply ONLY to U.S. installa-
tions.
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.

CondensateDrainTrap
This furnace removes both sensible and latent heat from the prod-
ucts of combustion. Removal of the latent heat results in con-
densation of the water vapor. The condensate is removed from
the furnace through the drains in the plastic transition and the vent
fitting. The drains connect to the externally mounted condensate
drain trap on the left or right side of the furnace.
The condensate drain trap supplied with the furnace MUST be
used. The drain line between the condensate drain trap and the
3 ,
drain location may be constructed of /4' PVC, CPVC pipe or suit-
able material.
The drain line must maintain a 1/4" per foot downward slope to-
ward the drain.
DO NOT trap the drain line in any other location than at the con-
densate drain trap supplied with the furnace.
Frozen water pipe hazard.
When activated an auxiliary safety switch will
cause a furnace not to operate.
During freezing temperatures the water pipes in
your home could freeze and burst causing water
damage to the home.
Do not leave the home unattended during freezing
temperatures, or shut off the water supply and
drain the pipes before leaving.
If possible DO NOT route the drain line where it may freeze. The
drain line must terminate at an inside drain to prevent freezing of
the condensate and possible property damage.
1. A condensate sump pump MUST be used if required by lo-
cal codes, or if no indoor floor drain is available. The con-
densate pump must be approved for use with acidic
condensate.
