Model CSA1

Chimney Stack Assist Kit

DESCRIPTION

The CSA1 Inducer assures draft in orpaned water heaters, oversized chimneys or when slight negative pressures in buildings prevent
proper exhaust of combustion gas. The venturi action of Tjernlund’s CSA1 Inducer starts air moving smoothly. These units are easy to
install and completely automatic in operation. Tjernlund’s unique design and durable construction makes them maintenance free.

IN THE EVENT OF PILOT OUTAGE

1. Push the reset button in the center of the Linear Limit Spillage Switch located
near the draft hood on the top of the water heater.

2. Follow water heater manufacturer’s re-lighting instructions attached to water
heater or located in water heater owner’s manual.

3. Turn the gas pilot knob at the top of water heater gas valve to “OFF” position.

WARNING: Gas pilot knob MUST REMAIN IN “OFF” POSITION FOR FIVE
MINUTES BEFORE PILOT IS RE-LIT. Perform steps 4 & 5 while waiting.

4. Visually verify that there is 115 volt power established to the CSA1.
Check fuse or circuit breaker, wall plug and electrical connections.

5. Visually verify that all electrical connections of control cord circuit are intact.

NOTE: Since the CSA1 cannot operate during a power outage, the safety interlock controls are designed to prohibit gas flow
to the water heater in the event of prolonged flue gas spillage. Follow the above procedures and water heater manufacturer’s instruc­tions for relighting the pilot when power has been restored.

SPECIFICATIONS

Maximum BTU/hr. input rating of equipment: 65,000.

* NOTE: 3” 90 Degree elbows are equivalent to 3 feet.

4” 90 Degree elbows are equivalent to 4 feet.

TOOLS NEEDED

1/4” Nut Runner 11/32” Nut Runner Tin Snips Drill
Gas Pipe Tape High Temp Silicone 1/4” Tube/Pipe Cutter Drill Bit Set
7/16” Open End Wrench 3/8” Open End Wrench 1/2” Open End Wrench

SEQUENCE OF OPERATION

1. Water heater thermostat calls for heat.

2. CSA1 activates and the burner fires simultaneously.

3. Burner & CSA1 shut down simultaneously when thermostat is satisfied.

If sustained flue gas spillage is detected by the Linear Limit Spillage Switch the Water Heater Safety Circuit is opened and pilot light is
extinquished. The Linear Limit spillage switch must be reset and the pilot relit to reestablish burner operation.

INSTALLATION RESTRICTIONS

WARNING

Failure to install, maintain and/or operate the CSA1 in accordance with manufacturer's instructions may result in conditions
which can produce bodily injury and property damage.

The CSA1 must be installed by a qualified installer in accordance with these instructions and all local codes or in their
absence in accordance with the latest editions of The National Fuel Gas Code (NFPA #54), Chimneys, Fireplaces, Vents, and
Solid Fuel Burning Appliances (NFPA 211), and the Occupational Safety and Health Act (OSHA) when applicable. Improper
installation can create a hazardous condition such as an explosion, fire, electrical shock or carbon monoxide poisoning
resulting in property damage, personal injury or death.

1. The CSA1 shall not be used on condensing heating equipment.

2. Gas-fired units without a draft hood / diverter must include a barometric draft regulator.

3. The CSA1 motor shaft must be mounted horizontally to prevent motor bearing wear.

4. The CSA1 shall not be installed where flue gas temperatures exceed 575

O

F (301°C) at the CSA1 inlet. Ambient room temperatures

must not exceed 104° F (40° C).

5. The installer must affix the wiring diagram label included with these instructions to the water heater casing adjacent to its rating plate.

6. The water heater may only be installed on the suction side of CSA1.

7. The installer must verify that the pilot safety controls on the water heater are in good operating condition before installation of the
water heater vent package.

8. The CSA1 must not be installed into any portion of a vent system which serves appliances other than the one vented by the CSA1.

9. Make certain the power source is adequate for the fan motor requirements. Do not add the CSA1 to a circuit where the total load is
unknown.

10. The installer must verify that the BTU/hr input of the water heater does not exceed the maximum input rating of the CSA1 (65,000 BTU/hr).

11. A safety inspection of the water heater must be performed before installation of the CSA1 as outlined in the International Fuel Gas
Code, (IFGC) Appendix D.
