SECTION 1 – 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.
