Section 1 — Installation

3.Refit the fitting and hose to the LP port and the blanking plug to the natural gas port (Figure 1.3).

4.Reverse the procedure to convert back to natural gas.

NOTE:

The natural gas adjustment screw is preset during installation and should not need any further adjustment.

Guardian Air-cooled Generators

1.7.1.1 6 kW, 8 kW and 10 kW Units (Non-SA)

These Guardian units are supplied with their own mounting pads and DO NOT require a concrete pad. Remove the packing material from the unit and unbolt the two 4-inch by 4-inch wooden blocks from the underside of the mounting base. Plug the holes with the plugs provided. Prepare the installation site to accept the mounting base. Provide adequate substrate to give sufficient drainage, i.e., a 3-inch deep section of pea gravel scattered under the mounting base.

1.7LOCATION AND MOUNTING

◆1.7.1 GENERATOR

Install the generator set, in its protective enclosure, outdoors, where adequate cooling and ventilating air always is 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 drift- ing, you may need to 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 3 feet of space on all sides.

•Where strong prevailing winds blow from one direction, face the generator air inlet openings into the prevailing winds.

•Install the generator as close as possible to the transfer switch. This reduces the length of wiring and conduit.

•Install the generator as close as possible to the fuel supply, to reduce the length of piping. HOWEVER, REMEMBER THAT LAWS OR CODES MAY REG- ULATE THE DISTANCE.

See Figure 1.4 (Pages 8-9) for generator and transfer switch major dimensions.

1.7.1.2 Sound Attenuated Units

Retain the generator compartment to a concrete slab with 1/4-inch masonry type anchor bolts. Be sure the bolts are long enough to retain the compartment. The slab should be at least 3 inches thick and should extend beyond the enclosure to a distance of at least 3 inches on all sides.

See Figure 1.5 (Page 10) for generator major dimensions.

◆1.7.2 TRANSFER SWITCH

1.7.2.1 6 kW, 8 kW and 10 kW Units (Non-SA)

The transfer switch shipped with this generator is enclosed in a NEMA 1 enclosure. This type of enclo- sure is intended for indoor use only. Follow these rules:

•Install the transfer switch indoors on a firm, stur- dy 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 corro- sive substance might drip onto the enclosure.

•Protect the switch at all times against excessive moisture, dust, dirt, lint, construction grit and corrosive vapors.

1.7.2.2 Sound Attenuated Units

All sound attenuated models have a transfer switch built into the enclosure and do not require a separate switch attachment.
