3.2.1. Stone chimney connection
The diameter of hole for connection to the chimney stack shall be about 20 mm larger than
the diameter of the heating flue outlet pipe, so the optimum clearance around the pipe is
about 10 mm.
If the designed pipe inlet to the stone chimney is at 90°, it is recommended to make the
inner edges of the chimney stack bore round (Figure 5) in order to reduce the resistance for
flue gas passage.
If you plan to use a heater rack, for example, then take into account the height of the heater
together with the rack when preparing the hole.
Procedure:
1. Install the heater on the place of permanent operation.
2. Install a water tank, if any. Keep in mind the requirements of its operations manual.
3. A valve can be installed on the connecting pipe, if additional adjustment of draft is
necessary. Install, if any.
4. Insert the connecting pipe into the stone chimney. Do not push the connecting pipe too
deep into the stone chimney, as you can block it.
5. Connect the heater with the pipe inserted into the stone chimney.
6. Ensure that all the pipe connections and the heater connection are reliable..
7.
Seal the gap between the pipe and the wall using non-combustible mineral wool, for
example.
8. Make sure that the air-tight seal is good. Add mineral wool, if necessary.
IMPORTANT! Familiarize yourself with the manufacturer’s detailed instructions on the safe
distances and installation of steel chimney elements, as well as the water tank.
Some installation options are depicted in Figure 5.
3.2.2. Heater connection to a steel chimney
Steel chimneys can be used for flue gas withdrawal. As a rule, it consists of separate
modules that can be coupled with each other, and that form a single duct for flue gas
withdrawal.
Chimneys can be installed directly from the heater through the ceiling and roof, or at an
angle through the wall.
If you plan to use a heater rack, for example, then take into account the height of the heater
together with the rack when preparing the hole for passage of the pipe through the wall.
The procedure for installing the pipe at an angle:
1. Install the heater on the place of permanent operation.
2. Install a water tank, if any. Keep in mind the requirements of its operations manual.
3. A valve can be installed on the connecting pipe, if additional adjustment of draft is
necessary. Install, if any.
4. Install all the necessary components of the outside chimney.
5. Insert the connecting pipe into the outside chimney.
6. Connect the heater with the pipe inserted into the outside chimney.
7.
Ensure that all the pipe connections and the heater connection are reliable.
Note: when installing the chimney from the heater directly through the ceiling and roofing
system, all the elements are installed consecutively.
