Step 6 — Connect Condensate Drain
NOTE: When installing condensate drain connection be sure to
comply with local codes and restrictions.
Model 574D disposes of condensate water through a 3/4 in. NPT
fitting which exits through the base on the evaporator coil access
side. See Fig. 3 & 4 for location.
Condensate water can be drained directly onto the roof in rooftop
installations (where permitted) or onto a gravel apron in ground
level installations. Install a field--supplied 2--in. (50.8 mm)
condensate trap at the end of condensate connection to ensure
proper drainage. Make sure that the outlet of the trap is at least 1 in.
(25.4 mm) lower than the drain-- pan condensate connection to
prevent the pan from overflowing (See Fig. 7). Prime the trap with
water. When using a gravel apron, make sure it slopes away from
the unit.
Connect a drain tube using a minimum of 3/4-- in. PVC or 3/4-- in.
copper pipe (all field--supplied) at the outlet end of the 2--in. (50.8
mm) trap. Do not undersize the tube. Pitch the drain tube
downward at a slope of at least 1-- in. for every 10 ft of horizontal
run. Be sure to check the drain tube for leaks.

Step 7 — Install Flue Hood
The flue assembly is secured and shipped in the return air duct.
Remove duct cover to locate the assembly (See Fig. 9 and 10).
NOTE: Dedicated low NOx models MUST be installed in
California Air Quality Management Districts where a Low NOx
rule exists.
These models meet the California maximum oxides of nitrogen
(NOx) emissions requirements of 40 nanograms/joule or less as
shipped from the factory.
NOTE: Low NOx requirements apply only to natural gas
installations.
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal
injury or death.
The venting system is designed to ensure proper venting.
The flue hood assembly must be installed as indicted in this
section of the unit installation instructions.
!
WARNING
Install the flue hood as follows:
1. This installation must conform with local building codes
and with the National Fuel Gas Code (NFGC), ANSI
Z223.1 (in Canada, CAN/CGA B149.1, and B149.2) or
NFPA (National Fire Protection Association) latest revision.
Refer to Provincial and local plumbing or wastewater codes
and other applicable local codes.
2. Remove flue hood from shipping location (inside the return
section of the blower compartment--see Fig. 9 & 10). Re-
move the return duct cover to locate the flue hood. Place
flue hood assembly over flue panel. Orient screw holes in
flue hood with holes in the flue panel.
