In order to keep door width minimum and boiler opening as small as possible, a double hinge solution
can be used. As double hinges add another degree of free movement, the boiler’s door must be
fastened on both sides. Slide-out doors with guide rails is also an option.
Boiler firebox lenght L Figure 5 must be at least 2 times longer than the length of burner’s burning
chamber (accordingly L=350 or 400 mm). Distance from the end burning chamber to firebox back wall L1
is about 180 or 200mm. The height of firebox must leave space at least 100mm (H1) for ash below
burning chamber and 100mm above burning chamber. Minimum boiler firebox dimensions for PV20a
are: L ≥350mm; H≥350mm and for PV30a L ≥400mm; H≥370mm.
The burner is mounted to boilers door using supplied oil burners mounting flange. Bolt hole circle
diameter and bolt sizes can be customized by using custom flanges. D1 and D2 given in Table 3 and Figure
6 are valid only with supplied flanges.
