WARNING
Should overheating occur or the gas supply fails to
shut o, do not turn o or disconnect the electrical
supply to the pump. Instead, shut o the gas supply
at a location external to the appliance.
WARNING
Do not use this boiler if any part has been under
water. Immediately call a qualied service technician
to inspect the boiler and to replace any part of the
control system and any gas control which has been
under water.
1.C System Shutdown
1. Turn OFF the main power switch.
2. Close the manual gas valves
.
3. If you think the unit might freeze, drain it. All water
must be removed from the heat exchanger, or
damage from freezing may occur. To completely
drain the boiler, rst drain the right side by opening
the boiler drain. Then remove the PRV and related
ttings. Then remove the top and left side panels.
Remove BOTH 1/2” plugs from the side of the boiler
located at the bottom of the casting. Once the water
is fully drained, reinstall the plugs and panels. Refer
to the Installation and Operating Manual.
4. Also be sure to protect the piping in the building
from freezing.
1.D Blocked Vent Safety Shut O
This boiler is equipped with a blocked vent safety
shut o system (BVSSS) to shut o the boiler if
the vent is obstructed for any reason. Operation
with an obstructed vent will cause the combustion
system to create Carbon Monoxide (CO). Do not
attempt to restart the boiler if it has been shut o by
the BVSSS. Turn the power o and call a qualied
Service Technician.
1.F Maintenance
1. Lubricate any motor bearings that are not sealed
bearings per the instructions.
2. If a strainer is employed in a pressure reducing
valve or the piping, clean it every six months or as
needed.
3. At start-up, and periodically thereafter, the burner
and pilot ames should be observed. If the ame
has the appearance of “sooting” tips, check for
debris near the orices. Clean any debris from
orice area and remove burners to ensure they are
debris free inside and out. If this doesn’t clear the
issue the heat exchanger likely needs cleaning.
4. Ensure Vent Damper motors open and close by
watching the connecting rod between the stack and
the motor housing. The boiler should never start if
the damper is not in the open position. If it does, it
is critical to safe operation that this gets repaired.
1.E Flame Roll-out Safety Shut O
This boiler is equipped with a ame roll-out safety
shut o system. The ame roll-out safety shut o is
located inside the front cover and and just above
the burners. The ame roll-out safety switch should
only be replaced by a qualied Service Technician.
If the boiler shuts o or will not start up due to the
ame roll-out safety switch, then turn the power o
and call a qualied Service Technician. .

8. Allow the boiler to operate until the target
temperature or high temperature set point is
reached. The yellow “target” LED or the yellow
“hi-temp” LED will light. The main burner and pilot
ame will turn o. The “ame” LED will turn o.
9. The damper will begin to close and the “v-pwr’’, “v-
sw”, and “limits” LEDs will turn o.
