Installing Rope On Bolted Covers (1” round or 1/2” round)
Upper covers:
Install 1” round rope seal with a ½” bead of high temperature caulk behind it to glue
the rope in place. Make sure to push the rope to the outside of the corners to mate properly with the
jamb (do not stretch the rope) and cut the joint to be compressed after inserting all the way around
for a custom fit. Cure for 24 hours, wet with WD40, replace cover and moderately tighten bolts
using the ¾” wrench. Start the boiler and tighten further if needed.
Lower Cover:
Install ½” round rope seal on the boiler jamb with a ¼” bead of high temperature
caulk behind it to glue the rope in place, keeping it lined up with the inner edge. Make sure rope is
cut so ends are tight to each other. Cure for 24 hours and then wet with WD40. Replace cover and
moderately tighten nuts using the 9/16” wrench. Start the boiler and tighten further if needed. Do not
over torque.
F. Pump
It is highly recommended that an additional pump or replacement cartridge be purchased from NC
or your dealer to have as a spare.
Inspection:
Before installing, inspect the pump shaft by removing the large silver screw to expose
the top of the shaft and turn back and forth with a screw driver to make sure the shaft was not
broken during shipping.
Broken shafts are not covered under warranty unless found and noted
before installation and startup.
Startup:
Make sure the lines are filled and prime the pump by cracking the upper pump flange to
bleed the air out of the impeller and volute.
IMPORTANT: The large, silver bleeder screw must
also be removed from the pump before running for the first time to bleed all air from the
bearings or the pump warranty will be void.
After priming the pump, remove and leave the
bleeder screw out, start the pump to finish bleeding all air out of the bearings, shut off the pump and
re-install bleeder screw. The pump may now run. Always run at high speed for the best efficiency of
the boiler and heat exchangers in the home.
Inspection & Maintenance:
Loosen the bleeder screw once a week (less often as experience
shows otherwise) to flush the bearings to maximize pump life, especially for system filled with poor
quality water (high iron, hardness, total dissolved solids, etc). It is highly recommended that a
customer have their own test kit to monitor treatment levels once a month and add if needed. If
when getting a sample for a test if the water is not perfectly clear, the boiler needs to be shutdown,
drained, flushed, re-filled & treated. Customers must still have a test done by their dealer or Wood
Boiler Solutions per the warranty with full details on our website (check annually):

To inspect the upper bearing and shaft, unplug the pump, close the valves on either side of the
pump to isolate (one should always be field installed right before the return line enters the water
jacket to be able to fully isolate the pump, lines and HX’s) and remove the bleeder screw to look at
the upper bearing to make sure it’s not worn out causing the rotor to scrub on one side of the
canister housing.
To inspect and clean the rotor and canister, take the 4 Allen screws off to remove the motor from
the volute.
***NOTE: The rotor shaft is ceramic. If it or the pump is dropped, hit, bounced or
jarred it can fracture and/or break. Use care when handling.***
Gently use a screwdriver to pop
the lower SS plate (also serves as the lower bearing) from the canister to pull the rotor out of the
canister. Use a wire brush to clean off any scale buildup from the rotor. To remove the canister first
remove the rotor, then tap on the bleeder screw to remove the canister from the motor (use this
procedure for replacing the entire cartridge as well). White vinegar or a calcium and lime cleaner
can assist for stubborn buildup.
Do not allow any liquids to enter the motor.
Squealing:
Comes from the bearings not having the air bled before running or not having enough
clearance caused by scale buildup around the bearings or around the rotor inside the canister
