All QHT BIASI B10 Series Boilers are shipped from the factory in assembled
boiler blocks. If, however, 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
NOTE: When cutting off excess length of draw rods, allow enough length to install
boiler jacket on the draw rods.
