Keep the hose parallel to the floor, with the insulation falling 10 to 12 feet in front. Where possible, back away from work to prevent packing.

Where work space is tight, prevent the insu- lation from packing by allowing it to blow off your hand.

Blow three or four joist spaces from one posi- tion by moving the hose to the right or the left. Always blow in the direction of joists, not across them.

Keep the hose close to the floor where insula- tion must go underneath obstructions such as cross-bracing and wiring. Insulation must be blown on both sides of this kind of obstruction.

Where an obstruction may cause a low spot to occur, move around, check this spot and, if necessary, fill in the low area.

Be sure that insulation is installed on both sides of obstructions such as solid cross- bracing and masonry chimneys.

If a batt or baffle is not used to block off the ends of joists, be sure that insulation is applied all the way to the outer edge of the plate.

When roof construction does not allow full depth to the ends of the joists, bounce the insulation off the underside of the roof to increase density in that area. Care should be taken not to block the eave vents. (See Figure 1.)

To prevent overheating of recessed light fixtures, do not insulate on top of or within three inches of such devices. To be in accordance with the current National Electric Code, provide a way of holding the insulation away by making a shield of noncombustible material. For local requirements, contact your local building department. (This warning does not apply to Type IC fixtures or fluorescent fixtures with thermally protected ballasts.)

Use only unfaced fiber glass insulation between wood framing and masonry chim- neys. Do not place insulation in air spaces surrounding metal chimneys or fireplaces.

Clearances around fossil fuel appliances should meet the requirements of the National Fire Protection Association (NFPA) or appliance manufacturer's recommendations.

Water pipes run in the attic area must be given protection since the attic tempera- ture during cold weather will now be very close to that of the outdoors. The severity of the winters and the location of the pipes will determine what is required to prevent freezing.

After the attic is blown, even out any high or low spots.

Do not remove the hose from the attic until the foreman has inspected and determined that no areas have been accidentally missed and that the correct number of bags has been installed.

Install a piece of batt insulation on top of areas where loose fill has not been applied, such as access panels, stair wells, and fan covers. The completed job should provide a continuous layer of insulation over the entire ceiling area.
