PROCEDURE IN EVENT OF POWER FAILURE Should your electricity go off during the heating season, there are several procedures that should be followed in order that you may continue to safely operate your heating system. These procedures apply to the solid-fuel boiler, as the gas or oil-fired boiler, if any, will be completely inoperative. 1. Locate any flow-check valves in the system (See Pg. 7), and completely unscrew the knob on the top of all these valves. (This will allow a certain

REFUELING THE BOILER CAUTION · Use extreme caution when refueling the boiler. If the door is opened too quickly, the unburned hot gases may ignite and cause a back puff. This is especially true with very dry wood. · DO NOT tamper with the chain on the draft regulator as it could cause the fire to burn out of control. · Keep ash and fuel doors closed if not refueling boiler. · DO NOT overload the boiler. Adjusting the Flue Gas Dam

WOOD BURNING Overview Burn dry and well-seasoned hardwood with a moisture content of 20% or less. Wood must be seasoned at least six months; however, it is preferable to season it for a year to eighteen months. Seasoned wood will not only reduce creosote but will also produce more heat. Some sea- soned hardwoods will yield 20-25% more heat. Wood-burners who ignore this advice are likely to have dirty chimneys and inadequate performance from their boilers. Theoretically, th

The Heat Value of Wood The following chart compiled by the United States Forest Products Laboratory indicates the amount of heat available per cord of wood from a few representative tree species. Other good to very good species would include apple, walnut, pecan, dogwood, cypress, sycamore and gum. The latter two are hard to split, as is elm. Available Heat Per Cord In Millions of BTU/ HR Green Wood Air-Dry Percent More Heat For Air-Dry Wood Species Ash 16.5 20.0 21 As

CREOSOTE Creosote condenses from the flue gases more quickly when the temperature in the chimney is low. The actual amount of creosote deposited is dependent on: 1. The amount of moisture in the flue gases. 2. The temperature of the stack, 3. The rate at which the wood is burned. 4. The amount of draft in the stack. 5. How completely the combustible elements in the flue gases have been burned in the combustion chamber. Most problems with creosote are due to insufficiently dry wo

Chimneys WARNING Do NOT connect this unit to a chimney flue serving another appliance. Downdrafts Downdrafts can result from improper chimney height, nearby buildings, tree that are taller then the chimney, and too large of a flue. To help minimize this problem, the top of the chimney must be at least three feet above the point at which it passes through the roof and two feet above the highest point of the roof. In addition, the chimney should be at least as high or higher than t

COAL FIRE DANGER COAL FIRES CAN PRODUCE POISONOUS GASES! All coal fires produce large quantities of carbon monoxide (CO) a highly poisonous gas. Exposure to this gas produces drowsiness, sleep, and in some cases, brain damage or even death. Since carbon monoxide is odorless and colorless, the victim is rarely aware that he or she is being overcome until it is too late. Normally, carbon monoxide burns as a blue flame over the coal bed, but under any of the following conditions, unb

The 3WOOD Design The 3WOOD Boilers are hot water generators that operate by combustion of hard wood or soft coal. They feature a high quality and extremely thick ASME class 20 cast-iron body, protected by high-density insulation that limits heat loss. The large heat exchange surface and the fins in the flue gas path ensure exceptional resistance to corrosion and very high efficiency that remains constant over time (self-cleaning effect). The combustion chamber and the upper door f
