2. Technical description
Fireplace inserts are intended for building into stoves in various interiors (apartments,
recreation buildings, restaurants). Romotop fireplace inserts are manufactured from quality
construction materials – cast metal,
CORTEN steel and quality construction and fittings steel, with stressed parts made of
HARDOX steel. The surface of steel constructions is protected by a refractory opaque paint.
Refractory paints are not anti-corrosive.
The combustion chamber of full-plate fireplace inserts is padded by removable chamotte fire
bricks, which are not connected by any paste material to prevent damage by heat dilatation.
The combustion chamber can be firmly closed by doors with special heat-resistant glass. The
glass not only increases the aesthetics of the flickering flames, but also facilitates pleasant
heat radiation. The glass also prevents the sparks from the burning wood and smoke from
entering the room. The floor of the combustion chamber is usually equipped with a
removable cast iron grate. Usually, a barrier, or alternatively a sheet metal or ceramic mould,
is placed in front of the grate to prevent the fuel falling and sliding onto the doors (front
window). Stoves with a grate include room for an ashpan under the grate. Some types allow
custom-configuration of the flue pipe throat for top- or back-side exhaustion.
Some types of fireplace inserts have a rotary exhaust flue pipe throat. The fireplace insert
design may include a single coating or be supplemented with an external coat of zinc-coated
sheet metal with outlets for connection to the heat system. Installation of a support fan is
recommended for vertical heat pipes longer than 4m.
Fireplace inserts equipped with a separate intake of primary and secondary combustion air
include the appropriate control elements. The primary air is taken to the burning fuel
(usually through the ashpan and grate) and is used for primary combustion. The secondary
air supports combustion of residual combustible gases in the exhaust, increasing the output
of the heater and significantly reduces the amount of pollutants escaping into the atmosphere.
The secondary air is mostly taken to the area above the burning fuel. Its presence causes the
cold air to roll around the inner side of the front glass.
