re-installed or replaced with new rope. Contact Nature’s Comfort or your dealer for new rope or
caulk if needed. This is a normal maintenance item and not a warranty issue.
Clean and coat entire threaded portion of all bolts for fuel door with a never-seize product if needed.
Adjusting Fuel Door
Slightly loosen one bolt on the hinge or latch (depending on where adjustment is needed) and tap
with a wood block to re-position and then tighten. Continue with other bolts one at a time as
needed. If the latch has no remaining adjustment, add washers behind the door handle to further
tighten the latch side.
Installing Rope Seal (1” round rope)
Re-position the door hinge and latch as far out as possible and install 1” round rope seal with a ½”
bead of high temperature caulk behind it to glue the rope in place. Use a thicker layer of caulk
where needed to push rope out for maximum adjustment. This method can accommodate up to a
½” of misalignment.
Make sure to push the rope to the outside of the corners to mate properly with the jamb (do not
stretch the rope). Put some caulk on the joint ends after cutting the rope and make sure the ends
are compressed or smoke will seep through. Over-extend the door latch open and bounce the door
closed twice to custom fit the seal to the jamb. If there are thick spots of caulk keeping the rope
pushed out, leave door open 24 hours until caulk behind rope is fully cured. Re-adjust door to
properly seal.
Pre-condition rope as explained in the “Operation” section. Start the boiler and tighten further if
needed.
E. Pump
It is highly recommended that an additional pump or replacement cartridge be purchased from
Nature’s Comfort or your dealer to have as a spare.
Water:
Since water quality characteristics greatly vary across the USA, some customers get much
longer life out of a pump than others. Filling a boiler with softened water, adding and maintaining
treatment so there’s 1,000-1,500ppm of nitrites is the best thing you can do for pump and boiler life.
While there is a one year warranty on our pumps (from customer’s date of purchase), they must first
be inspected and an attempt made to clean and put back in service before a pump or cartridge is
determined to be “failed”. Proper treatment and records must also be present for the warranty to be
honored. If a customer had a water test pass but adds water frequently due to boiling or over-filling
from improper operation this will bring down treatment levels quickly, possibly below the minimum
level of 1,000ppm and void the boiler warranty.
The pump that comes with the boiler is a cost-effective, entry-level pump that performs excellent for
most applications and water characteristics. A higher-end pump may be required if an application or
water quality is too aggressive (i.e. Armstrong’s E9.2 with a mechanical seal available from Nature’s
Comfort or your dealer. Other options also available)
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
