SCOTSMAN WOOD FURNACE – INSTRUCTION MANUAL
Scotsman Oct-06 5
1.4 MAXIMUM SOLID-FUEL CHARGE
The maximum level for a solid-fuel charge is the middle of the loading door, or the level
of the handle. DO NOT OVERFILL. The KERR SCOTSMAN Wood Furnace will accept
whole or split logs up to 34 in. (865 mm) long, but a 30 in. (765 mm) log length is
recommended for convenience and ease in handling.
Maximum damper gate opening is 11/16”. Do not tamper or adjust to greater opening in
an attempt to increase fire or over-firing and hazard may result.
1.5 MAINTENANCE
Some regular maintenance is necessary on the KERR SCOTSMAN furnace. A good
practice is to establish a routine for the storage of fuel, care of the appliance, and firing
techniques.
1.5.1 CLEANING (Fig S101-10)
The KERR SCOTSMAN Wood Furnace must be cleaned regularly to maintain top
efficiency. The furnace needs cleaning more often when burning green wood, or during
long periods of low fire. When the KERR SCOTSMAN Wood Furnace is first installed
the furnace heat exchanger should be checked visually from the firebox and smoke pipe
hole every week to determine the rate at which creosote or ash is accumulating within
the furnace. Cleaning should be done whenever there is more than 1/4 inch of build-up
on the heat exchanger or 3 inches of ash in the base. If the wood furnace is to be left
unused for an extended period of time (more than one month) then the appliance should
be cleaned of all ash and residual left from the burning of wood.
CLEANING PROCEDURE
o
Make sure fire is completely out and the furnace has cooled.
o
Remove the cleanout cover, located on the rear of the furnace heat exchanger, the
smoke pipe, and internal breech baffle.
o
The heat exchanger is now accessible for cleaning.
o
Use the scraper provided to remove all soot and ash from the furnace heat
exchanger and exposed surfaces.
o
Scrape all residues in the top heat exchanger towards the rear of the furnace
where it will fall into the firebox.
o
Always check flue pipe for creosote or ash build-up in the pipe and clean if
necessary.
o
Reinstall cleanout cover, internal breech baffle (See section 2.4.2) and smoke pipe
making sure that all joints are secured with at least 3 sheet metal screws.
o
Check chimney cleanout for ash build-up and remove any accumulation.
o
Residue may be removed from the firebox or left to be burnt during the next fire. It
is good practice to leave a layer of ash approximately one inch deep in the base of
the firebox.
