To ensure optimum operation and safety, we recommend that the installation should be carried out by an authorised HWAM retailer or a fitter recommended by the retailer. For an overview of HWAM distributors, visit www.hwam.com under “Retailer locations”.

The chimney must have an easily accessible soot door. Smoke pipe and chimney must always be suitable for a stove connection. Ask your HWAM dealer for more information.

Changing the smoke outlet from top outlet to rear outlet - HWAM 3760 (drawing J) If a wood-burning stove from the factory is supplied with a top outlet but you want to change it to a rear outlet, this can be done by following the instructions below.

• Built-in pipe sleeve (12). Fits smoke flue. • Wall rosette (13). Covers disruption to wall around pipe sleeve. • Joint (14). Sealed with packing material. • Smoke outlets (15) of the HWAM stove. • Smoke flue regulating damper (16). • Soot door (17).
Chimney The chimney is the “engine” of the stove and it is crucial for the functioning of the woodburning stove. The chimney draft provides a partial vacuum in the stove. This vacuum removes the smoke from the stove, sucks air through the dampers for the so-called glass pane rinse which keeps the glass free of soot, and sucks in air through both primary and secondary dampers for the combustion.

Banned fuel types It is not allowed to stoke a fire with the following: printed matter, plywood, plastic, rubber, fluid fuels, and rubbish such as milk cartons, lacquered wood or impregnated wood and fossil fuels. The reason that you should not apply any of the above is that during combustion they develop substances that are health hazardous and harmful to the environment.
Fuelling with coal, wood briquettes or pet coke The stove is not approved to use coal or pet coke as a fuel. However, wood briquettes can be used to fuel the fire and should be placed on the embers produced by the burned wood. Turn the regulator to its full clockwise position until the wood briquettes fully ignite.
Cleaning the glass We recommend wiping the glass after a fire. This is best done using a paper towel. Types of fuel The stove may be damaged by very high temperatures and the glass may turn white, for example. This can be avoided by never allowing the stove to burn with the ashpan open and taking great care with types of fuel that develop excessive heat, such as briquettes.
Cracks in the insulation have no effect on the efficiency of the stove. The insulation should be replaced, however, when it is reduced to less than half the original thickness due to wear and tear. HWAM Autopilot™ (Drawing G) ®...
