PHASE MCA MAX. CKT. BRK.RATED AMPS15 APart # 85477The GF200 is configured forNatural Gas from the factory.If conversion to Propane Gasis required, the conversion kitsupplied with the water heatermust be used.• Before connecting the gas supply, determine the gas type and pressurefor the water heater by referring to the rating plate. Use only the samegas type indicated on the rating plate. Using a different gas type willresult in abnormal combustion and malfunction of the water heater.Gas supplies should be connected by a licensed professional only.• The appliance and its gas connection must be leak tested beforeplacing the appliance in operation.• The water heater cannot be converted from natural gas to propane orvice versa without the supplied gas conversion kit. Do not attempt afield conversion of the water heater without a the gas conversion kit.Doing so will result in dangerous operating conditions and will void thewarranty.NTI is not liable for any property damage and/or personal injury resultingfrom improper conversions.WARNING4 Return Air DuctingThe return air may be delivered to theappliance via:a) either side;b) the back;c) the bottom; ord) any combination thereof, provided, inall cases, that access to at least one sidedoor remains clear (24” min.) for bloweraccess and maintenance.MAX CUTTINGBOUNDARY18” x 18”(324 sq. in.)MAXCUTTINGBOUNDARY14.5” x 24.5”(355 sq. in.)Side Back BottomIn all installations, an appropriate air filtration system is recommended andmust meet test requirements in UL 900. Failure to install and properly main-tain such a system could lead to damage to and/or premature failure of thespace heating components.In all cases, care must be taken to ensure that return ducting is sealed againstthe inlet, such that the entire air steam is directed through the air filter. Failureto do so could cause damage to the air moving equipment and clogging ofthe heating and/or cooling coils.NOTE: For details and recommendations on side, back or bottom return ducting seeGF200 Installation Manual.5 VentingMax length: 150’ Max length: 60’1 28Max number ofelbows: 8Max number ofelbows: 61 263” Venting1 in (25 mm) min.Combustion AirVentMaintain 12” min. clearance abovehighest anticipated snow level or grade.Combustion AirCombustion AirVentMaintain 12” min.

Refer to the manufacturer’s litera-ture for detailed information.** For installation in Canada, field-supplied plastic vent piping must complywith CAN/CGA B149.1 (latest edition) and be certified to the Standard. For TypeBH Gas Venting Systems, ULC-S636. Components of this listed system must notbe interchanged with other vent systems or unlisted pipes or fittings. All plasticcomponents and specified primers and glues of the certified vent system mustbe from a single system manufacturer and must not be intermixed with anothersystem manufacturer’s parts.
