ERIES
Startup — final checks
❏
Check 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
components 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.

1. Follow instructions in this manual to set and verify operation
of the boiler controls.
2. Follow low water cutoff manufacturers instructions (if used).
Have the following been done?
❏
ECO control set for the correct boiler model?
❏
Installation date and time entered into ECO control?
❏
Boiler and heat distribution units filled with water?
❏
Water chemistry verified per page 79?
❏
Sentinel X100 corrosion inhibitor added and water tested to
be within range?
❏
Automatic air vents, if used, opened one full turn?
❏
Air purged from system?
❏
Air purged from gas piping? Piping checked for leaks?
❏

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
condensate dish-to-heat exchanger joint, contact your
Weil-McLain representative for instructions to correct
the problem.
b. If the mirror test does not reveal a leak at the condensate
dish joint, but there are signs of weepage or other
indications that there might be leakage, follow the
procedure for checking the heat exchanger-to-condensate
dish seal on page 104.
❏
Additional field-installed controls tested as outlined by
control manufacturers? (Boiler should be operating and
should go off when controls are tested. Verify controls cause
automatic reset lockout or manual reset lockout as desired.)
❏
Additional field-installed limit control(s) set to system
temperature requirements? Balancing valves and controls
adjusted to provide design temperature to system?
❏
Flow adjusted/balanced for each zone of multiple zones
systems?
❏
Thermostat heat anticipator (if available) set properly?
❏
Boiler cycled with thermostats (and with DHW aquastat, if
installed) — Raised to highest setting and verified boiler goes
through normal startup cycle? Lowered to lowest setting and
verified boiler goes off?
❏
Natural gas input measured? (page 82)
❏
Incoming gas pressure checked by connecting manometer to
gas valve ahead of boiler? (Gas pressure must be at least the
minimum values given on page 21, with boiler operating at
high fire, and no more than 13 inches (330 mm) w.c. with
boiler operating or boiler off.)
❏
Observed several operating cycles for proper operation?
❏
Room thermostats set to desired room temperature (and
DHW aquastat, if installed, to desired DHW storage
temperature)?
