175231-YIM-A-070614 Unitary Products GroupOPTIONAL GAS HEATThese gas-fired heaters have aluminized-steel oroptional stainless steel, tubular heat exchangers withspark ignition with proven pilot.All gas heaters are shipped from the factory equippedfor natural gas use, but can be field converted to L.P./Propane with Kit Model # 1NP0418. See Gas HeatApplication Data Table.GAS PIPINGProper sizing of gas piping depends on the cubic feetper hour of gas flow required, specific gravity of the gasand the length of run. "National Fuel Gas Code" Z223.1(in U.S.A.) or the current Gas Installation Codes CSA-B149.1 (in Canada) should be followed in all casesunless superseded by local codes or gas utility require-ments. Refer to the Pipe Sizing Table 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 requirementspecifying a minimum diameter for gas piping.All units require a one-inch pipe connection atthe entrance fitting.Maximum capacity of pipe in cubic feet of gas per hour. (Based upona pressure drop of 0.3 inch water column and 0.6 specific gravitygas).GAS CONNECTIONThe gas supply line can be routed through the knock-outs located on the front of the unit or through theopening provided in the unit's base. Refer to theDimensions Figure 13 to locate these access open-ings. Typical supply piping arrangements are shown inthe figures on page 15. All shaded items are field-sup-plied.If gas supply line is routed through the unit's baseensure that the burner assembly can be removed formaintenance without disturbing the supply line. Thesupply piping and fittings must lie below the bottom gasmanifold to avoid interference with the burner assem-bly.Two grommets are shipped in the blower compartment(in parts bag taped to the blower housing) of every unitwith gas heat and should be used in the knockoutswhen the gas piping penetrates the front of the unit.After the gas supply piping has been installed, the bot-tom opening in the unit should be sealed to preventwater from leaking into the building.Gas piping recommendations:1. A drip leg and a ground joint union must beinstalled in the gas piping.2. When required by local codes, a manual shut-offvalve may have to be installed outside of the unit.3. Use wrought iron or steel pipe for all gas lines. Pipecompound should be applied sparingly to malethreads only.TABLE 4: GAS HEAT APPLICATION DATA0 To2,000 FeetAboveSea Level2,000 To4,500 FeetAboveSea LevelOutput Capacity (Mbh)Availableon ModelsGasRate(Ft./Hr.)Temp.Rise ºFAtFull Input0 To2,000 FeetAboveSea Level2,000 To4,500 FeetAboveSea LevelMax.
