Scheme 5. Installation of coaxial smoke exhauster
9.2.
Installation of separate pipes of smoke exhauster and air duct
Connecting separate pipes to the boiler is effectuated with a transitional set KHG 714061510 (not included
into the boiler’s supply package) or a channel separator 8023-10.000 (not included into the boiler’s supply
package).
The transitional set’s and the channel separator’s construction provides regulation of amount of
combustion inlet air with a butterfly damper. The amount of inlet air depends on pipe length and is defined
with the help of gas sensor. It is necessary to turn the butterfly damper clockwise, reducing the amount of
inlet combustion air, until the gas sensor detects the increase of CO level (more than 0,05%) in smoke
gases. After this you should turn the butterfly damper invertedly and fix.
Using separate pipes it is necessary to additionally take into account the following:
-The total maximum pipe length must not exceed 25 m. Each 90° branch pipe is equal 1 m pipe, each knot bend 45 ° -
0,5 m pipe;
-In case of possible appearance of condensation in the smoke exhauster pipe, a condenser tank 4 must be installed
before the boiler (see Scheme 6);
- The slope of the horizontal parts of the smoke exhauster pipe must be 3° towards the condenser tank (if there is one);
