WARNING:

Combustible air must not be drawn from a

contaminatedatmosphere.Excessiveexposure

to contaminated combustion air will result in

safetyandperformancerelatedproblems.

To maximize heat exchanger life, the combustion air

must be free of chemicals which form corrosive acidic

compounds in the combustion gases.

IMPORTANT NOTE:

Donotstoreanychemicalswithammableorcaustic

vaporsneartheventtermination.Someexamplesof

thesechemicalsare:

• CarbontetraChloride • Gasoline/Kerosene

VentTermination

This unit has been developed for use with a combination

heat exchanger condensate drain and venting system

designed to operate only with this type of system.

Condensate Drain and Vent Kits are available for purchase

as accessory items.

Horizontal ground mount applications can use P/N-922323

to attach the 13.25” x 2” PVC pipe within the control area of

this unit. Rooftop mount applications can use the downﬂow

condensate drain / vent kit (P/N-922485).

If Nordyne kits are not being used, see Appendix on page

43 or page 45 for your speciﬁc application.

WARNING:

This unit is intended for outdoor installation

only.Thisunitmustbeventedtotheoutdoors.

Noadditionalventingshallbeused.Donotvent

theunitthroughaconventionalventingsystem.

The vent and drain assembly must be installed to

assureproperoperationoftheunit.Figure 2 shows the

proper installation of the vent and drain assembly for both

horizontal and downﬂow applications. The fasteners used

to secure the vent and drain assembly have been included

in the kit. The following list summarizes the requirements

forthelocationoftheventsystemtermination:

• Thelocationoftheventterminationmustbeconsistent

withtheNationalFuelGasCode(ANSIZ223.1)orCAN/

CGA-B149 Installation Codes.

• The vent termination must be located at least 4 feet

horizontally from any electric meters, gas meters,

regulators, and relief equipment.
