20. Check combustion chamber insulation alignment
with the burner mounting plate. The combustion
chamber insulation igniter cutout should align
with the opening in the burner mounting plate. If
not properly aligned, remove the burner mount-
ing plate and reposition combustion chamber
insulation.
Misalignment of combustion chamber insulation
can cause unreliable boiler operation.
21. Hand tighten the burner mounting plate nuts to
hold the burner plate in place. Once all mount-
ing nuts are in place, use a wrench to tighten
using an alternating pattern until the gasket is
slightly compressed. See Table 2, page 7 for
torque specifications.
22. Re-assemble the blower onto the burner mount-
ing plate and reconnect the wiring harness con-
nectors. Tighten screws evenly. See Table 2,
page 7 for torque specifications.
23. Re-assemble the gas supply connection and
wire harness to the gas valve. Tighten the union
using two wrenches. See Table 2, page 7 for
torque specifications. Open the external manual
gas valve. Check gas piping for any leaks and
repair if necessary.
Do not check for gas leaks with an open flame.
Use a bubble test. Failure to check for gas
leaks can cause severe personal injury, death
or substantial property damage.
24. Re-attach the ignition cable (MCBA) and the
ground wire to the ignitor.
25. Reattach the air inlet elbow to the venturi.
26. Reposition the control panel.
27. Replace the front jacket panel and secure with
the thumb screw on the upper edge of the unit.
28. Install the top jacket access panel
29. Turn power to the unit “ON”. The unit is now
ready to be placed back into service.
COMBUSTION TEST/ADJUSTEMENT
The installer must perform a complete combustion
check to ensure the following combustion levels are
met at high and low input firing rates and the burn-
er is operating at optimum conditions.
The combustion testing and adjustments
must be performed by a qualified installer,
service agency or the gas supplier. All com-
bustion measurements must be perform with
calibrated equipment to ensure proper read-
ings and accuracy.
Failure to perform a complete combustion
test at both high and low input rates may
result in incomplete combustion and the pro-
duction of carbon monoxide, which can
cause severe personal injury, death or sub-
stantial property damage.
