Startup — final checks
(continued)
❏
Check Heat exchanger and vent seals
1. Operate the boiler on HIGH fire.
2. Using an inspection mirror, move the mirror around all heat
exchanger joints and vent pipe connections at the top of the
boiler and at the connection to the condensate dish.
3. A leak would appear as vapor on the surface of the mirror.
4. If there is any indication of a leak at any joint, immediately
shut down the boiler.
a. If possible, tighten the retaining screws or nuts (without
over-tightening).
b. If this does not correct the problem, disassemble the com-
ponents where the leak appeared. Use the procedures given
in the Maintenance section of this manual.
c. When disassembling components, inspect gaskets to see
if there is damage. Replace any damaged gasket.
d. Contact your Weil-McLain representative if the problem
cannot be addressed with the information provided in
this manual.
5. Condensate dish joint
a. If the inspection mirror check shows a leak at the con-
densate dish-to-heat exchanger joint.
or
If the mirror test does not reveal a leak at the condensate
dish joint, but there are signs of weepage or other indica-
tions that there might be leakage, the boiler must not be
operated until a new sealing ring is obtained. Follow the
instructions supplied with the sealing kit to disassemble
boiler components as necessary to access and replace
the seal.
