Install Instructions

Determine where to install the remote sensor based on the following requirements:

a. The tip of the probe or

extension must be installed

above the minimum safe

water level, as determined by

the boiler manufacturer.

b. Probes must be installed ver-

tically if they are more than 5"

(127mm) long.

c. There must be a minimum 1/4"

(6.4mm) clearance between

the probe and any grounding

surface inside the boiler.

STEP 1 - Where to Install the Remote Sensors

IMPORTANT: Remote sensors MUST

be installed in a tapping on the boiler.
