Install the plate assembly in the boiler, evenly spaced as possible. Set the yoke over the
bolt, install the nut and make it hand tight to keep the plate from moving.
Using the correct size socket wrench, tighten the nut one quarter turn. See Figure 7. If the
gasket leaks while the pressure is being brought up on the boiler, tighten the nut only
enough to stop leaking. See Figure 8.
Check the gaskets for leakage for the next three days after installation and if leakage is
detected tighten only enough to stop it.
WARNING: EXCESSIVE TIGHTENING WILL FLATTEN OUT THE GASKETS TO A POINT
WHERE THEY WILL NO LONGER BE ABLE TO SEAL. DO NOT TIGHTEN MORE
THAN IS REQUIRED TO SEAL
IMPROPER PRESSURE ON GASKET OF HANDHOLE PLATE

Cleaning the Flue Passages
Under normal operating conditions the flue passages do not need to be cleaned. If poor
combustion has been experienced and soot has built up on the flue passages they can be
cleaned following this procedure. Before cleaning have your boiler technician check the
stack temperature and combustion efficiency to make sure that cleaning is necessary.
Do not disassemble the jacket top ring without first obtaining a millboard top gasket.
This
gasket can become brittle over time and will be impossible to reinstall after removing. This
can cause combustion gasses to leak and can cause a dangerous situation. If your boiler
was built after February 1991 you will
also need
an upper hand hole gasket, part number
480210.
