SCOTTY WOOD FURNACE – INSTRUCTION MANUAL
Scotty Oct-06 6
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 SCOTTY Wood Furnace will accept whole or split logs up to 27 in. (686 mm)
long, but a 24 in (610 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 SCOTTY 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 S102-6)
The KERR SCOTTY 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 SCOTTY 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. See fig. S102-6
CLEANING PROCEDURE:
1) Make sure fire is completely out and the furnace has cooled.
2) Remove the smoke pipe located on the rear of the furnace heat exchanger.
3) The heat exchanger is now accessible for cleaning.
4) Use the scraper provided to remove all soot and ash from the furnace heat
exchanger and exposed surfaces.
5) Scrape all residues in the top heat exchanger towards the front of the furnace
where it will fall into the firebox.
6) Always check flue pipe for creosote or ash build-up in the pipe and clean if
necessary.
7) Reinstall smoke pipe making sure that all joints are secured with at least 3 sheet
metal screws.
8) Check chimney cleanout for ash build-up and remove any accumulation.
9) 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.
