The unit will run on natural gas or LP gas, but it has been factory set to run on natural gas. Section 1 — General Information Bryant Air-cooled 7 kW, 12 kW and 15 kW Generators Should the primary fuel need to be changed to LP gas, the fuel system needs to be reconfigured. See Section 1.9 for instructions on reconfiguration of the fuel system. Recommended fuels should have a Btu content of at least 1,000 Btus per cubic foot for natural gas; or at least 2,520 Btus per cubic foot for LP gas. Ask the fuel supplier for the Btu content of the fuel. Required fuel pressure for natural gas is 5 inches to 7 inches water colum (0.18 to 0.25 psi); and for liquid propane, 11 inches to 14 inches of water column (0.4 to 0.5 psi). NOTE: Any piping used to connect the generator to the fuel supply should be of adequate size to ensure the fuel pressure NEVER drops below 4 inches water colum for natural gas or 10 inches water column for liquid propane for all load ranges. 1.8 FUEL CONSUMPTION *Natural gas is in cubic feet per hour. **LP is in gallons per hour/cubic feet per hour. *** Values given are approximate. Model # Nat. Gas (*) LP Vapor (**) 1/2 Load Full Load 1/2 Load Full Load 6/7 kW 66 119 0.82/30 1.47/54 12 kW 152 215 1.53/56 2.08/76 13/15 kW 156 220 1.58/58 2.40/88 DANGER Gaseous fuels such as natural gas and liquid propane (LP) gas are highly explosive. Even the slightest spark can ignite such fuels and cause an explosion. No leakage of fuel is permitted. Natural gas, which is lighter than air, tends to collect in high areas. LP gas is heavier than air and tends to settle in low areas. 1.9 LOCATION . 1.9.1 LIFTING THE GENERATOR To lift the generator, insert pipe having sufficient strength and diameter through the lifting holes which are located near the unit’s base (see Figure 1.1 and 1.2, page 5). You may also lift the unit using a hook and hoist method provided you utilize a spreader bar to ensure that the lifting lines clear the roof panel. ! Excercise caution when lifting the unit manually as it may shift on lifting pipes during transportation, which may result in injury. . 1.9.2 PLACEMENT Install the generator set, in its protective enclosure, outdoors, where adequate cooling and ventilating air is always available. Consider these factors: • Install the unit where air inlet and outlet openings will not become obstructed by leaves, grass, snow, etc. If prevailing winds will cause blowing or drifting, consider using a windbreak to protect the unit. • Install the generator on high ground where water levels will not rise and endanger it. • Allow sufficient room on all sides of the generator for maintenance and servicing. A good rule is to allow three feet of space on all sides. • Where strong prevailing winds blow from one direction, face the generator air inlet openings to the prevailing winds. • Install the generator as close as possible to the fuel supply, to reduce the length of piping. • Install the generator as close as possible to the transfer switch. HOWEVER, REMEMBER THAT LAWS OR CODES MAY REGULATE THE DISTANCE. The genset must be installed on a level surface. The base frame must be level within two (2) inches all around. . 1.9.3 TRANSFER SWITCH 1.9.3.1 7 kW, 12 kW and 15 kW Units The transfer switch shipped with this generator is enclosed in a NEMA 1 enclosure. This type of enclosure is intended for indoor use only. Follow these rules: • Install the transfer switch indoors on a firm, sturdy supporting structure. • To prevent switch distortion, level the switch if necessary. This can be done by placing washers between the switch enclosure and mounting surface. • Never install the switch where water or any corrosive substance might drip onto the enclosure. • Protect the switch at all times against excessive moisture, dust, dirt, lint, construction grit and corrosive vapors. DANGER When lifting or hoisting equipment is used, be careful not to contact overhead power lines. The generator’s weight of more than 300 pounds requires proper tools, equipment and qualified personnel to be used in all phases of handling and unpacking. If the AUTO/OFF/MANUAL switch is not set to its OFF position, the generator can crank and start as soon as the battery cables are connected. If the utility power supply is not turned off, sparking can occur at the battery posts and cause an explosion. ! Bryant 7 Section 1 — General Information Bryant Air-cooled 7 kW, 12 kW and 15 kW Generators 1.10 BATTERY INSTALLATION Fill the battery with the proper electrolyte fluid if necessary and have the battery fully charged before installing it. Before installing and connecting the battery, complete the following steps: 1. Set the generator's AUTO/OFF/MANUAL switch to OFF. 2. Turn off utility power supply to the transfer switch. 3. Remove the 7.5A and 15A fuses from the generator control panel. Battery cables were factory connected at the generator (Figure 1.5). Connect cables to battery posts as follows: Figure 1.5 – Battery Cable Connections...
