THE PROBLEM:
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 SOLUTION:
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.
   Damper closes during off cycles to prohibit cold
      air entry and warm air loss.
   Helps replace air vented by exhaust fans,
       fireplaces, etc.
   Reduces negative pressure, a major cause of flue
      gas spillage and radon gas entry.

Steps to Selecting the Right Combustion Air IN-FORCERTM

                        MODELS PAI-1G & PAI-2G                             MODELS PAI-1O & PAI-2O
                        (For 24 VAC Control Circuits)                           (For 115 VAC Control Circuits)

Step 1)     Determine the required CFM from Table A based on equipment type and BTU/hr. input of the heater(s).

Step 2)     Calculate the equivalent length of the 3" PVC inlet pipe and the 6"outlet duct (if used) from Table B.

Step 3)     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.

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.
