NEW TJERNLUND PAI-2G COMBUSTION AIR IN-FORCER
RESIDENTIAL / LIGHT COMMERCIAL
Incomplete combustion or poor draft due to inadequate combustion air in too-tightly constructed buildings can result in carbon monoxide creation, poor equipment efficiency, reduced equipment life and nuisance service calls.
The IN-FORCER mechanically draws outside air indoors on demand to provide fresh air for safe and efficient operation of fuel burning equipment.
The Combustion Air IN-FORCERTM offers all these advantages:
Affordably priced and installs fast with simple electrical interlock.
Reduces cold air drafts through windows,doors, fireplaces caused by excessive negative pressure.
Automatic regulated control of incoming fresh, combustion air.
Light indicates IN-FORCER is operating properly.
Uses indoor air to temper outdoor air for increased comfort.
Interlock shuts down burner if intake elbow is blocked or performance is significantly reduced.
Reduces negative pressure, a major cause of flue gas spillage and radon gas entry.
Steps to Selecting the Right Combustion Air IN-FORCERTM
Determine the required CFM from Table A based on equipment type and BTU/hr. input of the heater(s).
Calculate the equivalent length of the 3" PVC inlet pipe and the 6"outlet duct (if used) from Table B.
Referencing Table C and your calculated equivalent length, verify that the CFM performance listed in Table C is equal to or greater than that determined in Table A. Select Model PAI-1 or PAI-2 Series based on CFM necessary and control circuit voltage.
REQUIRED CFM BASED ON EQUIPMENT TYPE AND BTU/HR INPUT (TABLE A)
CALCULATING EQUIVALENT LENGTH (TABLE B)
The performance shown is based on equivalent feet. 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 the 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.
