Heatmax Furnace Installation and Operation Manual Note that hardwood trees like oak, maple, ash and beech are slower growing and longer lived than softer woods like poplar and birch. That makes hardwood trees more valuable. The advice that only hardwoods are good to burn is outdated. Old, leaky cast iron furnaces wouldn’t hold a fire overnight unless they were fed large pieces of hardwood. That is no longer true.
Heatmax Furnace Installation and Operation Manual Wood should be split to a range of sizes, from about 3” to 6” (75 mm to 150 mm) in cross section. Having a range of sizes makes starting and rekindling fires much easier. Often, the firewood purchased from commercial suppliers is not split finely enough for convenient stoking. It is sometimes advisable to resplit the wood before stacking to dry. 3.2.
Heatmax Furnace Installation and Operation Manual • • • • softwoods like pine, spruce, and poplar/aspen can be dry enough to burn after being stacked in the open for only the summer months hardwoods like oak, maple and ash can take one, or even two years to dry fully, especially if the pieces are big firewood dries more quickly when stacked in the open where it is exposed to sun and wind; it takes much longer to dry when stacked in a wood shed firewood that is ready to burn has a moisture content between1
Heatmax Furnace Installation and Operation Manual 4 Operating your furnace 4.1 Your first fires Two things will happen as you burn your first few fires; the paint cures and the internal components of the furnace are conditioned. As the paint cures, some of the chemicals vaporize. The vapours are not poisonous, but they do smell bad. Fresh paint fumes can also cause false alarms in smoke detectors. So, when you first light your furnace, be prepared by opening doors and/or windows to ventilate the house.
Heatmax Furnace Installation and Operation Manual After the kindling fire has mostly burned, you can add firewood pieces until you have a fire of the right size for the conditions. 4.2.2 The top down fire The top down fire starting method solves two problems with the conventional method: first, it does not collapse and smother itself as it burns; and second, it is not necessary to build up the fire gradually because the firebox is loaded before the fire is lit.
Heatmax Furnace Installation and Operation Manual 4.3 Maintaining wood fires 4.3.1 General advice Wood heating is very different than other forms of heating. Do not expect steady heat output from your furnace. It is normal for its temperature to rise after a new load of wood is ignited and for its temperature to gradually decline as the fire progresses. This rising and falling of temperature can be matched to your household routines.
Heatmax Furnace Installation and Operation Manual 4.3.2 Raking charcoal Rekindle the fire when you notice that the room temperature has fallen. Do not operate your furnace at too low a setting. Keep the air inlet opened long enough during the fire start-up to prevent the fire from smouldering, which could stain the glass. You will find most of the remaining charcoal at the back of the firebox, furthest from the door. Rake these coals towards the door before loading.
Heatmax Furnace Installation and Operation Manual 4.3.4 Control of the air supply Once the firewood, firebox and chimney are hot, you can begin to reduce the air supply for a steady burn. As you reduce the air supply to the fire, two important things happen. First, the firing rate slows down to spread the heat energy in the fuel over a longer period of time. Second, the flow rate of exhaust through the furnace and flue pipe slows down, which gives more time for the transfer of heat from the exhaust.
Heatmax Furnace Installation and Operation Manual 4.3.5 Building different fires for different needs Using the air control is not the only way to match the furnace’s heat output to the heat demand. Your house will need far less heat in October than in January to be kept at a comfortable temperature. If you fill the firebox full in fall weather, you will either overheat the space or turn the furnace down so much that the fire will be smoky and inefficient.
Heatmax Furnace Installation and Operation Manual 4.3.5.4 Maximum burn cycle times The burn cycle time is the period between loading wood on a coal bed and the consumption of that wood back to a coal bed of the same size. The flaming phase of the fire lasts for roughly the first half of the burn cycle and the second half is the coal bed phase during which there is little or no flame.
Heatmax Furnace Installation and Operation Manual 4.4.2 Combustion efficiency Even the best-built wood furnaces should be well used to obtain maximum efficiency. A furnace that overheats will not transfer more heat to the inside, as this will increase the heat loss through the chimney. Using a thermometer will help you control the temperature of your furnace and achieve optimum performance when controlled manually. 4.4.
Heatmax Furnace Installation and Operation Manual 5 Maintaining your wood heating system 5.1 Furnace maintenance Your new furnace will give many years of reliable service if you use and maintain it correctly. Some of the internal components of the firebox, such as firebricks, baffles and air tubes, will wear over time under intense heat. You should always replace defective parts with original parts (see Appendix 6: Exploded diagram and parts list).
Heatmax Furnace Installation and Operation Manual If you do get brown stains on the glass you can remove them with special cleaners for wood furnace glass doors. Do not use abrasives to clean your furnace’s door glass. The deposits that form on the glass are the best indication of the quality of your fuel and how well you are doing in operating the furnace. Your goal should be clear glass with no brown stains.
Heatmax Furnace Installation and Operation Manual 5.1.4 Replacement of the glass and gaskets After a year or more of use, the gasket of the door will compress and become hard which can allow air to pass. You can check the air tightness of your door gasket by closing and locking the door on a piece of paper. Check all around the door. If the paper slides easily anywhere, it is time to replace the gasket. Use a good quality gasket that you can purchase from your dealer.
Heatmax Furnace Installation and Operation Manual 1. Remove the door (F) and place it on a stable work surface, handle down. 2. Using pliers, remove the door gasket (A). 3. Using a scraper or a small flat screwdriver, remove the adhesive left in the gasket grove in the door then clean the surface using a commercial vacuum. 4. Use a Phillips screwdriver or a power drill to remove the screws (B) that holds the glass retainer (C). 5. Remove the glass frame (D) 6.
Heatmax Furnace Installation and Operation Manual Do not abuse the glass door by striking or slamming shut. Do not use the furnace if the glass is broken. To change the glass, perform the same operation described above. 5.1.5 Cleaning and painting the furnace Do not attempt to clean or paint the furnace when the unit is hot. Painted surfaces can be wiped down with a damp cloth. Plated or enameled surfaces may be scratched by abrasive cleaners.
Heatmax Furnace Installation and Operation Manual Smoke pipe and exchangers must be inspected regularly during the heating season. Access to the exchangers is easy and does not require tools; 1. Unscrew the wing nut (B) and remove the washer (C) on the exchanger access door. 2. Move the baffle of the combustion chamber forward.
Heatmax Furnace Installation and Operation Manual 3. Use the tool provided, clean the three exchanger pipes. 4. Dirt in the lateral exchangers fall into the combustion chamber at the rear.
Heatmax Furnace Installation and Operation Manual 5. Dirt in the central exchanger will be removed from the front or the rear of the furnace. If you remove dirt from the central exchange to the back of the furnace, remove the black pipe connector in order to dispose of the dirt. 6. Then, check that the baffle is clear of ash and reposition it in its original position towards the back of the combustion chamber.
Heatmax Furnace Installation and Operation Manual 7. Close the exchanger access door and secure it using the washer (C) and wing nut (B). 8. If you have performed maintenance from the back part of the furnace, reinstall the black pipe connector and secure it with three screws. 5.2 Chimney and chimney connector maintenance 5.2.1 Why chimney cleaning is necessary Wood smoke can condense inside the chimney connector and chimney, forming a combustible deposit called creosote.
Heatmax Furnace Installation and Operation Manual WARNING: IT IS RECOMMENDED TO CLEAN THE HEAT EXCHANGERS THOROUGHLY AT THE END OF SEASON IN ORDER TO PREVENT CORROSION). 5.2.3 Cleaning the chimney Chimney cleaning can be a difficult and dangerous job. If you don’t have experience cleaning chimneys, you might want to hire a professional chimney sweep to clean and inspect the system for the first time. After having seen the cleaning process, you can decide if it is a job you would like to take on.

Heatmax Furnace Installation and Operation Manual 7.5.
Heatmax Furnace Installation and Operation Manual 8 The venting system 8.1 General The venting system, made up of the chimney and the connecting pipe between the furnace and the chimney, acts as the engine that drives your wood heating system. Even the best furnace will not function safely and efficiently as intended if it is not connected to a suitable chimney. The heat in the flue gases that pass from the furnace and chimney connector into the chimney is not waste heat.
Heatmax Furnace Installation and Operation Manual 8.2.1 Factory-built metal chimneys These are sometimes referred to as ‘high temp’ chimneys because they have the special characteristics to withstand the temperatures that can be created by wood burning furnaces. Factory-built chimneys are tested as a system with all the necessary components for installation. The instructions provided with the chimney by its manufacturer are the only reliable source of installation guidelines.
Heatmax Furnace Installation and Operation Manual 8.3 Minimum chimney height The top of the chimney should be tall enough to be above the air turbulence caused when wind blows against the house and its roof. The chimney must extend at least 1 m (3 ft.) above the highest point of contact with the roof, and at least 60 cm (2 ft.) higher than any roof line or obstacle within a horizontal distance of 3 m (10 ft.). 8.
Heatmax Furnace Installation and Operation Manual Good system design Inside chimneys are preferred because even when no fire is burning, there is normally upward flow in the system. Inferior system design Outside chimneys are a problem because when no fire burns they will go into cold backdraft if the furnace is installed low in the house. 8.4.2 Why the chimney should penetrate the highest heated space When it is cold outside, the warm air in the house is buoyant so it tends to rise.
Heatmax Furnace Installation and Operation Manual 8.5 Supply of combustion air In Canada, wood furnaces are not required to have a supply of combustion air from outdoors because research has shown that these supplies do not give protection against house depressurization and may fail to supply combustion air during windy weather.
Heatmax Furnace Installation and Operation Manual 8.7.1 Installation of single wall chimney connector The chimney connector assembly has been called ‘the weak link’ in the safety of wood heating systems because failure to install the connector properly (which has been common in the past) can result in house fires. The best flue pipe assembly is one that rises straight up from the furnace to the base of the chimney with no elbows.
