• Read these instructions carefully.

• Failure to follow them and/or improper installation may

cause explosion, property damage and injuries.

• Installation must be done with the supervision of a

licensed burner technician.

• Check the ratings in the specifications to make sure that

they are suitable for your application.

• Never perform work if gas pressure or power is applied,

or in the presence of an open flame.

Mounting

• The valve must be de-energized and the gas supply shut

off before mounting the CPI.

• Disconnect all power to the switch before beginning to

prevent electrical shock and equipment damage.

Mounting Procedure (reference Fig. 1 above)

• IMPORTANT!! Before mounting the brass adapter

to the valve or to the CPI 400, use your fingers to

verify that the pin slides freely inside the brass

adapter. If this pin does not slide freely, apply a

large enough force to the appropriate side to free

the pin.

• Using a 5mm hex wrench, remove the plug and its o-ring

located at the bottom of the valve.

• Verify that the brass adapter has a clean o-ring and its

threads and the groove into which the brass adapter

mounts, are clean and in good condition.

ATTENTION

• Once installed, perform a complete checkout including

leak testing.

• Verify proper operation after servicing.

• The system must be installed, used, and maintaned to

meet all applicable national and local code requirements

such as but not limited to NFPA 86, CSD-1, ANSI Z21.13,

UL 795, NFPA 85, or CSA B149.3.

MOUNTING

• Mount the brass adapter into the valve.

• Use a 9/16" (14 mm) open end wrench and torque to 44

in-lbs (5Nm), which is about 1/4 turn (after finger tight).

DO NOT overtighten.

• Mount the CPI switch onto the brass adapter. Push the

CPI housing towards the valve until it stops.

• Turn/Position the CPI so that the wiring and conduit con-

nection apply the least amount of torque as possible.

• Tighten the set screw so that the CPI housing is secured

to the brass adapter.

• Do not turn the CPI 400 after tightening the set screw;

this may strip the brass adapter. The brass adapter could

loosen and the assembly may leak.

• Perform a leak test to verify that no leakage occurs around

the o-ring.
