Tjernlund PAI-1 & 2O Combustion Air In-Forcer 8504038 Rev A 05/01 - Manual (Page 3)

2
GENERAL INFORMATION
These units have been factory tested and rated in accordance with AMCA standard 210, test code for air moving devices.
Each IN-FORCER is electrically factory line tested before shipment.
After opening carton, Inspect thoroughly for hidden damage. Fan wheel should rotate freely. If any damage is found, notify freight
carrier and your distributor immediately and file a concealed damage claim.
INSTALLATION RESTRICTIONS
1. The electrical load controlled through the Fan Proving Switch must not exceed its nameplate ratings.
2. Observe proper location of intake elbow as described on page 3.
WARNING: Improper installation, adjustment, alterations, service or maintenance can cause injury or property damage. Refer to
this manual. For assistance or additional information consult a qualified installer, service agency or the equipment supplier.
CAUTIONS
1. Failure to install, maintain and/or operate the IN-FORCER in accordance with manufacturer’s instructions may result in conditions
that can produce bodily injury and property damage.
2. The IN-FORCER must be installed by a qualified installer (an individual properly licensed and/or trained) in accordance with all
local codes or in their absence, in accordance with the appropriate National Fire Protection Association #31, #54, #211 and the
National Electric Code.
3. The IN-FORCER motor shaft must be mounted horizontally and with discharge facing down to prevent motor bearing wear and
ensure proper operation of the Fan Proving Switch.
4. The IN-FORCER must be installed level to ensure proper damper operation.
5. Disconnect power supply when making wire connections and servicing the IN-FORCER. Failure to do so may result in personal
injury and/or equipment damage.
6. Make certain the power source is adequate for the IN-FORCER requirements. Do not add the IN-FORCER to a circuit where the
total electrical load is unknown.
WARNING: The IN-FORCER CFM outputs are estimates that will assure adequate combustion air is supplied if the appliance is
functioning properly. However, in the event that there is an appliance malfunction, such as a cracked heat exchanger or clogged
flue, there is no guarantee that additional combustion air will eliminate carbon monoxide spillage into the home.
SAFETY INSPECTION OF A PREVIOUSLY USED OIL APPLIANCE
(Perform prior to IN-FORCER installation)
The following procedure is intended as a guide to aid in determining that an appliance is properly installed and is in safe condition for
continuing use. This procedure is based on central furnace and boiler installations and it should be recognized that generalized pro-
cedures cannot anticipate all situations. Accordingly, in some cases deviation from this procedure may be necessary to determine
safe operation of the equipment.
A. This procedure should be performed prior to any attempt at modifications of the appliance or installation of the IN-FORCER.
B. If it is determined there is a condition which could result in unsafe operation, the appliance should be shut off and the owner
advised of the unsafe condition.
The following steps should be followed in making the safety inspection:
1. Visually inspect the venting system and determine there is no blockage or restriction, leakage, corrosion or other deficiencies
which could cause an unsafe condition.
2. Inspect burner and primary control for proper operation.
3. Applicable only to furnaces: Inspect heat exchanger for cracks, openings or excessive corrosion. Check both the limit control
and fan control for proper operation.
4. Applicable only to boilers: Inspect for evidence of water or combustion product leaks. Determine that the water pumps are in
operating condition. Test low water cutoffs, automatic feed controls, pressure and temperature limit controls and relief valves in
accordance with the manufacturer's recommendations to determine that they are in operating order.
