draw-up rod clamps on the other. These items are all located in the Draw-Up Kit.

See Figure 12.

CAUTION

Do not apply pressure directly on threaded tappings on front and rear sections with draw-up channels during assembly procedures.

Rods should be approximately centered in openings so that rods and couplings (when used) do not drag on pipe thread in end section tappings.

WARNING

READ THE STATEMENTS BELOW BEFORE ATTEMPTING TO USE HYDRAULIC EQUIPMENT.

•Release pressure in ram pumps before attempting to remove clamps.

•Do not stand in line with draw-up rods at either end when hydraulic pressure is being applied. As a safety measure, ends of draw-up rods should be covered while sections are being drawn in case rods should snap while under tension.

•Do not operate ram against draw-up coupling.

•Do not operate pump after ram has reached stroke limit.

(Partial Block Draw-Up)

The large draw-up rod lugs with dual holes cast in the four (4) corners of each casting. Starting with the upper holes in the back section, install four (4) 5/8” x 9¾” long tie rods along with washers and nuts. Continue installing the tie rods alternating from the upper to lower set of holes in draw-up lugs until front section is secured. Be certain that all sections are drawn up iron to iron at all three nipple ports.

h. Excess length of draw-up rods must not extend

beyond front and rear section to ensure proper fit

of jacket, adjust accordingly. Tighten all tie rod

nuts until finger tight. Then tighten them an

additional ½ turn with a wrench.

C. HYDROSTATIC TEST — After the boiler sections

have been assembled, it is essential that the boiler be

hydrostatically tested before the canopy, flue cover

plates, jacket, or piping is installed.

1. Tankless Heater Installation

If boiler is ordered with tankless heaters, install

heaters with the gaskets provided. Table IV gives

Block Positions (Hydraulic Draw-Up)

e. Draw-Up Sections

Use hydraulic rams to draw up sections by applying pressure alternately on the draw-up rods. When rams reach stroke limit, release pressure in ram pumps and then move clamps to new position.

f. Continue to draw-up until all sections make contact at the ground joints.

g. After all sections have been drawn up, but before removing the hydraulic rams and draw-up rods, the 9¾” long tie rods must be installed.

the maximum number of heaters permissible per

assembly and the heater ratings.

2. Plug all boiler tappings and fill boiler completely

with cold water.

CAUTION

Do not install gauge until after hydrostatic testing the boiler. Gauge failure may result.

3.All completed boilers must satisfactorily pass the prescribed hydrostatic test.
