PRECAUTIONS
DO NOT BEGIN INSTALLATION UNTIL YOU READ
THE FOLLOWING PRECAUTIONS.
!
WARNING
1. Failure to turn off electric or main gas supply
to heating system could cause personal injury and/or property damage by shock, gas
suffocation, fire, and/or explosion.
2. Do not use this control on circuits exceeding
specified voltage. Higher voltage will damage the control and may cause shock or fire
hazard.
3. NEVER USE FLAME OR ANY KIND OF SPARK
TO CHECK FOR GAS LEAKS–COULD CAUSE
FIRE AND/OR EXPLOSION.
!
CAUTION
1. Do not short out terminals on gas valve or
primary control to test. Short or incorrect
wiring can cause equipment damage, property damage, and/or personal injury.
If you do not follow these instructions exactly, a fire or explosion may
result, causing property damage, personal injury or loss of life.
4. DO NOT USE WIRE JUMPER on pilot systems, such as standing pilot, proven pilot, or
spark-to-pilot ignition–a fire and/or explosion may result.
5. Do not use a control set for natural gas with
LP gas, or a control set for LP gas with
natural gas. Personal injury and/or property
damage, gas suffocation, fire, and/or explosion may result.
2. This control is not intended for use in locations where it may come in direct contact
with water. Suitable protection must be provided to shield the control from exposure to
water (dripping, spraying, rain, etc.).
