User maintenance procedures
Check condensate drain system
1. While the boiler is running check the discharge end of the condensate drain tubing.
2. Make sure no flue gas is escaping from the condensate drain tubing by holding your fingers
in front of the tubing discharge.
3. If you do notice flue gas escaping from the drain tubing, this indicates a dry drain trap. Call
your qualified service technician to install a Weil-McLain condensate drain line check valve kit.
Under some circumstances a GV vent system may not produce enough
condensate to keep the condensate trap full of liquid. If the trap is not full,
small amounts of flue products can be emitted into the boiler room through
the condensate drain line. Contact a qualified service technician to install a
Weil-McLain condensate drain line check valve kit.
4. Verify that the condensate drain tubing is unobstructed by squeezing it. Check the entire
length of the condensate drain tubing, including the corrugated tube between the boiler vent
outlet tee and the boiler jacket side.

Check boiler relief valve

1. Inspect the boiler relief valve and the relief valve discharge pipe for signs of weeping or leakage.
2. If the relief valve often weeps, the expansion tank may not be working properly. Immediately
contact your qualified service technician to inspect the boiler and system.
Test low water cutoff (if installed)
1. If the system is equipped with a low water cutoff, test the low water cutoff periodically during
the heating season, following the low water cutoff manufacturer's instructions.
Clean vent termination & air intake screens
1. Remove all lint and debris from both the boiler air intake screen and the flue discharge screen.
2. The boiler control module will sense blockage of the air intake or flue and lockout if the
blockage is excessive. It will signal the failure by flashing the appropriate indicator lights on
the control board.
3. If removing the debris does not allow the boiler to operate correctly afterwards, contact your
qualifed service technician to inspect the boiler and vent/air systems.
