6. Boiler Block Assembly:

All Linear series boilers are shipped either as an assembled boiler block or a knock-down boiler block. If the block came unassembled, or if the assembled block needs to be split for installa- tion purposes, please read the following:

To assemble split blocks, move the sections into a line facing each other. Sections may be slid along boards placed underneath the sections. Inspect nipple ports for damage or burrs. Remove any burrs by brushing the port very lightly. Wipe the push nipples and nipple ports with a clean cloth.

Apply a film of nipple compound to both the nipple and port. Install the nipple in the port and then seal it by hitting it with a rubber mallet. Apply section sealant to one section only and slide sections together. If the boiler came in sections, you will want to draw the sections together 2 or three at a time to insure that the blocks are coming together properly. Install the four draw rods and draw the sections together evenly (measure with yardstick). The longer draw rods should be installed on the top of the boiler. The shorter draw rods are installed on the bottom of the boiler. The bottom draw rods should not extend past the front section. Draw the sections together until sections make iron-to-iron contact at a point around the top and bottom ports of each section. Check to insure that the combustion cham- ber is sealed using a flash light or other lighting device. Place the flashlight into the combustion chamber and look for light on the floor or surrounding walls (this is best done in a dark room). If light appears out of the boiler use a high temperature caulk to fill in the gaps between the block sections.

DO NOT OVER TIGHTEN DRAW RODS
