Biasi SG Series
All SG series boilers are shipped from the factory in assembled boiler blocks. If the
block needs to be split into sections for ease of delivery, please read the following:
To assemble split blocks, move sections into parallel and facing each other. Sections
may be slid along boards placed underneath the sections. Inspect nipple ports for damage or
burrs. Remove any burrs by scraping 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 by hitting with a hammer cushioned with a block of wood.
Apply section sealant to one section only and slide sections together. Install the four draw
rods and draw the sections together evenly (measure with yardstick). Draw the sections
together until sections make iron-to-iron contact at a point around the top and bottom ports of
each section.
DO NOT OVER TIGHTEN DRAW RODS
After assembly of boiler block, seal all joints with boiler gasket and remove boards. NOTE:
When cutting off excess length of draw rods, allow enough length to install boiler jacket on
the draw rods.
