(A) -
Distance from the heater connection to the ceiling.
(B) -
Minimum safety distance to flammable materials on both sides of the heater,
(C) -
be-
hind and
(D) -
in front of it.
(E) -
Distance to the walls made of non-combustible materials.
(F) -
Distance to the walls made of non-combustible materials in the alcove.
The gap between the heater and the walls made of non-combustible materials (E, F) is nec-
essary for air circulation.

Heater installation
IMPORTANT! Ensure proper floor levelling for the heater installation; possible slants of the
heater and the chimney are precluded.
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.
