1.0 OPERATING INSTRUCTIONS
1.1 INTRODUCTION
Congratulations on your purchase of the KERR TW2000 Wood-Fired Boiler. Developed in
Atlantic Canada, this KERR Boiler has been designed to allow you to heat your home with
wood, one of North America’s most abundant fuels. The heat exchanger materials meet ASME
(American Society of Mechanical Engineers) requirements for domestic boilers. Designed with
you in mind, the KERR TW2000 Wood-Fired Boiler will provide you with many years of safe,
efficient central heating.
To ensure you have a clear understanding of the operating procedures of this boiler, please
take the time to read the remainder of this section on operating procedures. If you have any
questions, your KERR DEALER will be happy to answer them for you.
1.2 WOOD-BURNING
The TW2000 Wood-Fired Boiler will burn most wood fuels, however it is recommended that
only dry seasoned hardwood be used as much as possible since it affords cleaner, safer and
more efficient operation. Burning seasoned hardwood will leave less ash, soot and creosote
residue and will require fueling less often. Use smaller loads of wood on warmer days.
WARNING: DO NOT use chemicals or fluids to start the fire or during operation.
DO NOT burn driftwood or manufactured logs (compressed wood).
Before adding fuel to an existing fire turn up the thermostat for about five minutes or lift damper
chain to hold damper fully open for about one minute before opening the loading door. This
action will allow residual smoke to clear from the combustion chamber and reduce smoke
entering the basement during refueling.
Twice daily refueling may be sufficient in modern well-insulated homes. However, KERR
recommends that small fuel loads be added morning, noon and early evening and late
evening, rather than large quantities infrequently. A small intense fire will burn more efficiently
than a large smoldering fire in the TW2000 Wood-Fired Boiler and will produce less creosote.
When refueling the TW2000, the remaining coals should be raked to the front of the
combustion chamber before adding any new fuel. New fuel shall be placed on and behind the
hot coals. This will help create a more even and efficient burn. The TW2000 owner should
attempt to gauge fuel quantities with outdoor temperatures; a little practice will provide greater
satisfaction and efficiency.
WARNING: This Boiler is not to be used with an automatic stoker.
Keep firing door tightly closed and maintain door seal in good condition.
