User manual TJERNLUND PAI-G & O RESIDENTIAL LIGHT COMMERCIAL COMBUSTION AIR IN-FORCERS 8500386 REV A 1102

[. . . ] The safe and cost-effective way to ensure adequate combustion air for gas and oil-fired heating equipment or to improve air quality problems caused by tight construction. Features of all IN-FORCERS s Installation is fast, simple and economical. s Built-in damper closes during off cycles to prohibit cold air entry and warm air loss. [. . . ] s Increases security--fresh air is brought in while windows and doors are locked.

To determine the equivalent feet of an installation, add the length of the 3" PVC inlet pipe plus the equivalent length of any elbows. Do not include intake elbow or gooseneck equivalent loss, they have already been factored into the performance data. Use the same method to determine the equivalent feet if a 6" outlet duct is installed.

Easy-to-follow instructions and examples of these methods can be found in the IN-FORCER'S manual. Life-Style: The IN-FORCER may be cycled according to the occupants' life-style. One scenario would be to set the timer to operate the IN-FORCER for several hours straight in the morning and evening when a family is most active cooking, using bathroom facilities and doing laundry.
