1.4Maximum Solid-FuelCharge, 1.5Maintenance

TW2000 WOOD-FIRED BOILER – INSTRUCTION MANUAL

DO NOT store wood within installation clearances or within the space required for charging or ash removal.

1.4Maximum 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 or extreme over-heating may result, causing warpage or damage to the boiler.

The KERR TW2000 Wood-Fired Boiler will accept whole or split logs up to 34 in. (864 mm) long, but a 30 in. (762 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.

1.5Maintenance

Some regular maintenance is necessary on the KERR TW2000 boiler. A good practice is to establish a routine for the storage of fuel, care of the appliance, and firing techniques.

1.5.1Cleaning

The KERR TW2000 Wood-Fired Boiler must be cleaned regularly to maintain top efficiency. The boiler needs cleaning more often when burning green wood, or during long periods of low fire. When the KERR TW2000 Wood-Fired Boiler is first installed the boiler 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 Boiler. Cleaning should be done whenever there is more than ¼ inch of build-up on the heat exchanger or 3 inches of ash in the base.

CLEANING PROCEDURE:

(1)Make sure fire is completely out and the Boiler has cooled.

(2)Remove the smoke pipe located on the top of the Boiler.

(3)Remove the overhead baffle in the combustion chamber if necessary.

(4)The heat exchanger is now accessible for cleaning.

(5)Use the scraper provided to remove all soot and ash from the boiler heat exchanger and exposed surfaces.

(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. Also reinstall the overhead baffle.

(8)Check chimney cleanout for ash build-up and remove any accumulation.
