WARNING: To prevent

electrical shock or equip-

ment damage, power must

be off during installation or servicing

of the control. To prevent serious

burns, the boiler should be thorough-

ly cooled before installing or servic-

ing control. Only qualified personnel

may install or service the control in

accordance with local codes and

ordinances. Read instructions com-

pletely before proceeding.

HOT WATER BOILERS: Probe must be

installed at or above the minimum safe

water level established by the boiler

manufacturer. The probe may be

installed directly in the boiler if a suit-

able tapping is available (A), in the riser

(B), or in the header (C) or (D).

IMPORTANT: To assure proper

drainage, pipe diameter should be no

less than 1" on installations in vertical

piping and no less that 1

⁄4" on installa-

tions in horizontal piping.

Loosen the two control box cover bind-

ing head screws and remove the cover.

Slide keyhole slots over probe mounting

screws and tighten screws (with either a

1/4" hex head driver or flat screwdriver).

Connect the ring terminal wire lead to the probe terminal

stud and secure with the lock washer and wing nut provided.

With the power removed, proceed with installation and

wiring according to Method A or B described on next page.

TEE MOUNTING: If a field fabricated tee is used, make sure that the tee drains thoroughly when the

water level falls below it, and that it conforms to the spacing requirements described in Step 3.

Models equipped with the shorter EL1214-SV probe can be installed in most standard reducing tees.

Safgard cast iron tees are also available to accommodate all probe models (See page 4).
