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.
