Refer to Figure 5 for information concerning rear and bottom supply and return air duct openings.
ROOF CURB
On applications when a roof curb is used, the unit must be positioned on the curb so the front of the unit is tight against the curb.
FILTERS
Single phase units are shipped without a filter and is the responsibility of the installer to secure a filter in the return air ductwork or install a Filter/Frame Kit (1FF0110 for the D1NA018 thru D1NA042 and 1FF0112 for the D1NA048 and D2NA060).
A filter rack and filters are standard on three phase units.
NOTE: Filters on the D1NA048 and D2NA060 units require the use of a 516" nut driver for removal.
Filters must always be used and must be kept clean. When filters become dirt laden, insufficient air will be delivered by the blower, decreasing your units efficiency and increasing operating costs and wear-and-tear on the unit and controls.
Filters should be checked monthly especially since this unit is used for both heating and cooling.
CONDENSATE DRAIN
A condensate trap is recommended to be installed in the condensate drain. The plumbing must conform to local codes. Use a sealing compound on male pipe threads. Install the condensate drain line (34“ NPTF) to spill into an open drain.

Maximum Capacity of Pipe in Cubic Feet of Gas Per Hour (Based Upon A Pressure Drop of 0.3 Inch Water Column and 0.6 Specific Gravity Gas).
035-18265-001-A-0202
GAS PIPING
Proper sizing of gas piping depends on the cubic feet per hour of gas flow required, specific gravity of the gas and the length of run. “National Fuel Gas Code” Z223.1 or CAN/CGA B149.1 or
.2 should be followed in all cases unless superseded by local codes or gas company requirements. Refer to Tables 4 and 5.
The heating value of the gas may differ with locality. The value should be checked with the local gas utility.
NOTE: There may be a local gas utility requirement specifying a minimum diameter for gas piping. All units require a 1/2 inch pipe connection at the gas valve.
GAS CONNECTION
The gas supply line can be routed through the hole located on the left side of the unit. Refer to Figure 5 to locate these access openings. Typical supply piping arrangements are shown in Figure 2.

3.Use wrought iron or steel pipe for all gas lines. Pipe dope should be applied sparingly to male threads only.
CAUTION: If flexible stainless steel tubing is allowed by the authority having jurisdiction, wrought iron or steel pipe must be installed at the gas valve and extend a minimum of two (2) inches outside of the unit casing.
WARNING: Natural gas may contain some propane. Propane, being an excellent solvent, will quickly dissolve white lead or most standard commercial compounds. Therefore, a special pipe dope must be applied when wrought iron or steel pipe is used. Shellac base compounds such as Gaskolac or Stalastic, and compounds such as Rectorseal #5, Clyde's or John Crane may be used.
4.All piping should be cleaned of dirt and scale by hammering on the outside of the pipe and blowing out the loose dirt and scale. Before initial start-up, be sure that all of the gas lines external to the unit have been purged of air.
5.The gas supply should be a separate line and installed in accordance with all safety codes as prescribed under “Limitations”. After the gas connections have been completed, open the main shut-off valve admitting normal gas pressure to the mains. Check all joints for leaks with soap solution or other material suitable for the purpose. NEVER USE A FLAME.
6.The furnace and its individual manual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.48 kPa).
The furnace must be isoulated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.48 kPa).
FLUE VENT HOOD
The flue vent hood with screen is not shipped attached. This hood must be installed to assure proper unit operation. The hood must be fastened to the outside of the side gas control/electrical compartment with the screws provided in the bag attached to the inside of the gas control/electrical compartment, see Figure 3.
The unit is controlled by a conventional four wire heating/cooling thermostat common to this class of equipment.
WARNING: FLUE HOOD SURFACES
