INSTALLATION

When Installing This Product…

1.

Read these instructions carefully. Failure to follow them 
could damage the product or cause a hazardous 
condition.

2.

Check the ratings given in the instructions and on the 
product to make sure the product is suitable for your 
application.

3.

Installer must be a trained, experienced service 
technician.

4.

After installation is complete, check out product 
operation as provided in these instructions.

WARNING

Fire or Explosion Hazard.
Can cause severe injury, death or property damage.

1. Disconnect power supply before wiring to avoid 

electrical shock, explosion, or equipment damage.

2. If a new gas control is being installed, turn off gas 

supply before starting installation. Conduct Gas 
Leak Test after gas control is installed.

3. In an LP gas installation, remember that LP gas is 

heavier than air and will not vent upward naturally. 
Do not operate electric switches, lights, or 
appliances until you are sure that work area is free 
of gas.

4. Never install an S89 where water can flood, drip, or 

condense on the device. It can malfunction if it gets 
wet.

5. Never try to use a device that has been damp or 

wet—replace it.

6. If the control might be exposed to water or moisture, 

install it in a suitable waterproof enclosure.

7. Any replacement S89 must have the same or shorter 

lockout time 

and

 the same or longer delay timing as 

the original control.

Replacement Application Requirements

If this is a replacement application, follow the appliance 
manufacturer instructions, if available. The manufacturer 
usually provides wiring diagrams, start-up and checkout 
instructions, and service procedures for their appliance. If the 
manufacturer instructions are not available, use the general 
guidelines that follow.
