Step 2 - Connect Fuel - Buffalo GEN7500TRI Instruction Manual

Step 2 – Connect Fuel
Sulfur, water, dust, etc. are harmful for engine. If the gas supply source (LPG) contains these harmful elements, user must use filter to remove sulfur,
water etc. and clean gas. Otherwise, the engine service lifetime will be shortened.
Choose either LPG or Gasoline or Natural Gas fuel.
If using LPG, first connect the regulator that was included with the generator to Propane Fuel Tank, then connect the other end to the Gas Inlet.
(Fig A). Make sure the LPG cylinder is vertical and securely positioned.
If using NG, replace the LPG adapter with the NG adapter. (fig 4). NOTE: Adapters are labeled with LPG and NG (fig 5).
Directly connect to the NG system with a gas hose no less than 3/8" (inside diameter), no longer than 10 ft (3m) and to the gas inlet. (fig 3)
Do not use the LP regulator hose for NG.
If using LPG or NG, be sure that the carburetor is free of gasoline.
If using gasoline fuel, add Unleaded gasoline only with an octane rating of 87 or higher.
Maximum Capacity: 6.2 Gallons
