Installation
IMPORTANT:
This technical bulletin is intended as a guide for
authorized service personnel installing or servicing
Johnson Controls products. Carefully follow all
instructions in this sheet and all instructions on the
appliance. Limit repairs, adjustments, and servicing to
the operations listed in this sheet or on the appliance.
!
WARNING: The system must meet all applicable codes. Improper
installation may cause fire, explosions, property
damage, and injuries or death.
Carefully follow all instructions in this sheet and all instructions on the
appliance. Limit repairs, adjustments, and servicing to the operations listed
in this sheet or on the appliance.
!
WARNING: Fire or explosion hazard. Shut off the gas supply at
the main manual shutoff valve before installing or
servicing the GM Series valve.
1. Ensure that the maximum ambient temperature is not exceeded
(see Table 2).
2. Check the power supply voltage for compatibility with the required
valve voltage. All wiring must conform to national and local electrical
codes and regulations.
3. When installing the valve on the manifold, the gas must flow through
the valve body in the direction indicated by the arrow on the body. If
the valve is installed with the gas flow opposite the arrow, leakage can
occur.
4. Shut off the gas at the main manual shutoff valve.
5. Mount the valve. It is recommended that the flanges be mounted to
the pipe separately with the valve then mounted between the
two flanges. The filter plate assembly should be installed (using the
longer bolts) between the inlet flange and the valve.
