There are two options for mounting the KLA: Surface Mount (page 5) or the recommended Flush
Mount (page 3). Skip to the required section for installation instructions.
Flush Mount Installation (Recommended)
1. Place the KLA Enclosure Box next to the stud taking into consideration the finished wall
thickness. (The front of the KLA Enclosure Box should be installed flush with the finished
wall).
Figure 1: Flush Mount Installation (Protrude to finished wall thickness)
2. Attach the KLA Enclosure Box to the stud through the slotted cutouts using appropriate
screws.

Mounting the Gas Solenoid
Solenoid Installation Recommendations:
•A licensed installer should complete this section following all National and Local Codes.
•Ensure that 120VAC solenoids are ONLY used with the KLA-HV (High-Voltage), while 24VDC
solenoids are used exclusively with the KLA-LV (Low-Voltage) [See Electrical Specifications].
•ISIMET’s S-Series Enclosure is recommended, which will typically include a Solenoid Assembly
(see below).
•The solenoids should be installed with an access panel for maintenance and/or service.
•Remove the solenoid assemblies and flush the piping systems prior to initial startup.

Wiring the KLA
A licensed electrical contractor should perform all 120VAC wiring following all electrical codes and
procedures. Low-Voltage and control wiring should be isolated from any line voltages and use 18 AWG
minimum. Warning: All Inputs MUST be Dry-Contact (Voltage-Free)!
