V. Maintenance
A. Cleaning Out Ash
Moisture combined with ash will eat through a boiler in short order and ash corrosion is NOT
covered under warranty.
With our firebrick grate and ash pan, ashes can be removed while the fire is still burning. Clean ashes
out frequently to prevent damage from corrosion. Make sure to turn off power to the blower before
removing ash pan and wear heavy gloves and safety glasses as ash pan will be hot. Put back in place
quickly once empty as free-flowing air will cause fire to burn too hot.
B. Creosote - Formation and Need for Removal
1. When wood is burned slowly (smoldering) it produces tar and other organic vapors which combine with
expelled moisture to form creosote. This occurs on a larger scale when there is too much moisture
content in the wood being used or during milder weather. The creosote vapors condense in the cooler
chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. Smaller
intense fires, shorter idle times & dry, seasoned wood will help limit this. When ignited, this creosote
makes an extremely hot fire. If a chimney fire occurs, shut down the blower. Do not spray water to keep
the steel cool as this will damage the boiler, simply keep the water jacket full.
2. The chimney and any connectors must be inspected frequently (at least twice a month) during the
heating season to determine if a creosote buildup has occurred. If creosote has accumulated it should
be removed to reduce the risk of a chimney fire.
3. All creosote and ash must be cleaned from the firebox frequently as ash mixed with moisture is very
corrosive and will shorten the life of your boiler if not maintained properly. Check daily until experience
shows how often cleaning is necessary.
C. Door Seals
Check rope seals on the loading door and ash pan periodically during the heating season as they will
compress. Loosen the bolts on the hinge and/or latch to re-position the main door for tightening the seal
if necessary. If the latch has no remaining adjustment, add washers behind the door handle to further
tighten the latch side. If there is no more adjustment available and the door is not sealing properly, the
rope seal must be removed, cleaned & loosened up, reversed and re-installed or replaced with new
rope. For installation, re-position the door hinge and latch as far out as possible and install the rope
seal with a liberal amount of high temperature caulk behind it for maximum adjustment. Make sure to
push the rope to the outside of the corners to mate properly with the jamb (do not stretch the rope).
Close the door once to custom fit the seal to the jamb, then leave door open until caulk behind rope is
fully cured (ensure there are no raised portions that will leave gaps!). Re-adjust door to properly seal.
Contact your dealer or Nature’s Comfort for new rope or caulk if needed. This is a normal maintenance
item and not a warranty issue.
D. End of Season
1. Power:
Turn off power supply at the appropriate circuit breaker
2. Chimney:
Inspect & Clean. Cap the chimney to keep rain water out.
3. Firebox &
Remove ashes, soot, and hardened deposits from the fire chamber
Ash Tray:
by using a putty knife and/or wire brush. Coat the inside of firebox with a light
coat of motor oil or WD-40 to protect the steel during the off-season.
4. Doors:
Oil door hinges and latch.
5. Plumbing:
Ensure fittings on both ends of tubing are tight at all locations.
6. Water Treatment Unless you are using anti-freeze or glycol, make sure your water is tested and
has enough Nature’s Comfort water treatment so there will be no rust or
corrosion. See warranty for further details.
Moisture from rain or condensation must not be allowed to accumulate in the firebox or ash pan
during the off-season. Failure to perform preventive maintenance may result in severe corrosion
and major damage to the boiler. This is NOT covered under warranty.
