It is preferable to install an R1" multistage pump with a flow rate capacity that always meets current
system needs. Install block valves immediately downstream and upstream of the pump to enable
removal of pump for repairs, replacement etc. without discharging the water from the system.
-
Install the spigot used for filling and discharging the system on the return pump at the lowest point of
the system.
-
Prior to startup, fill the system with water as follows:
a)
for open circuits, fill the system using the spigot for filling and discharge, until the water starts to
leak from the expansion vessel’s overflow pipe,
b)
for closed circuits, system pressure (operating pressure) should be 0.1
÷
0.15 mPa (1
÷
1.5 bar).
In both cases, slowly fill the system so that air can escape through air release valves. If the valves are not
opened automatically, open them manually until water starts to leak, and then close them.
-
Do not discharge water from the heating system even during summer, because it protects the inside of
the system from oxidation (corrosion).
-
If you will not use the boiler for a longer period during winter and no antifreeze mixture is pored into
the system, it is best if you discharge water from the system. While discharging the system, open the
radiator valves, air release valves and other system blocking elements.
-
You may not light a fire if water in the boiler is frozen or if there is not enough water in the boiler.
8. STARTUP AND LIGHTING THE FIRE
Before you light the fire for the first time, the entire local (central) heating system should be filled with water
and well bled, and the stove should be properly connected to the chimney, as described in the foregoing items.
NOTE: The stove may not be used without water. It must be connected to the system, which is connected
to consumers (radiators) with the power of no less than 14 KW.
When the system is cold, power regulator (combustion regulator, thermostat) damper located on the ash pan
door (Fig. 1, Items 10 and 19) should be open. Pull out the damper open and close knob (Fig. 1, Item 4 and Fig.
15). This opens the damper and enables you to light the fire. Later, when the fire has been burning for a while,
set the damper to an appropriate position, depending on the chimney draw and desired power, and push the
knob back. This closes the damper and enables maximum yield of combustion and thereby better heating,
cooking and baking. During this process, fire box and ash pan door (Fig. 1, Items 7 and 9) must be closed, if
you need controlled burning. Fire lighting damper is opened only while the fire is being lit (10 to 15 minutes).
Fire box and ash pan door may be opened and closed manually or using the wrench shown on Figure 6.
Fire is lit in the stove the same way as in other solid fuel stoves. Fire is lit with the ash pan door and grate
holder open (Fig. 9 and Fig. 10). Grate holder (Fig. 1, Item 13 and Fig. 9) is opened by lifting and pulling.
When the fire starts burning, you may load wood or coal, but do not fill the firebox at once and divide the fuel
necessary to fill the firebox in two or three portions and load them into the firebox in 10
÷
15 minute intervals.
A stove loaded in such way can burn for 1 to 6 hours, depending on combustion strength in the stove or on the
regulator (thermostat) setting.
