PRECAUTIONS
DO NOT BEGIN INSTALLATION UNTIL YOU READ THE FOLLOWING PRECAUTIONS.
! WARNING |
|
If you do not follow these instructions exactly, a fire or explosion |
|
may result causing property damage, personal injury or loss of life. |
|
|
|
|
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.
4.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.
!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.
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.).
INSTALLATION
NOTE
All piping must comply with local codes, ordinances, and/or national fuel gas codes.
1.Turn off electrical power to the system at the fuse box or circuit breaker. Also turn off the main gas supply.
2.If replacing an existing valve, disconnect all plumbing and electrical connections from the old control.
3.The control may be installed in any position except upside down (see figure 1). The arrow on the bottom plate indicates the direction of gas flow through the valve.
4.You should use new pipe that is properly chamfered, reamed, and free of burrs and chips. If you are using old pipe, be sure it is clean and free of rust, scale, burrs, chips, and old pipe joint compound.
5.Apply pipe joint compound (pipe dope) or teflon tape that is approved for all gases, only to the male threads of the pipe joints. DO NOT apply compound or teflon tape to the first two threads (see figure 2 for typical piping connections).
6.If you are using a vise or open-end wrench to hold the valve while installing piping, do not tighten excessively, as this may damage the valve.
7.See wiring pages 3-6 when making electrical connections. After all gas and electrical connections are completed, turn gas on and check for gas leaks with leak detection solution or soap suds. Bubbles forming indicate a leak. SHUT OFF GAS AND FIX ALL LEAKS IMMEDIATELY.
