4 Boiler Foundation and Minimum Boiler Clearances

Boiler foundation preparations
It is required that the boiler is placed on a level, smooth
concrete base, of sufficient strength. The width of the
platform must be 33 1/2". Length L 1 is the platform
length. It is required to cement in either a 4" x 1/4" flat
steel plate or a 4" x 2" x 1/4" angle iron, as shown in
Figure 2; Table 3 shows dimensions.

Minimum wall clearances
The recommended wall clearances must be observed in
order to open the burner door, assemble the boiler and
allow sufficient access for boiler maintenance.
(See Figures 3 and 4 for details).
The burner door is field adjustable to hinge right or left.
Recommended clearances:
Wall clearance W1: minimum 12".
Wall clearance W2: Burner length A + 4", minimum 43".
Wall clearance W3: Boiler length L + 40".
Wall clearance W4: 1/2 Boiler length + 20".
Absolute minimum clearances:
Wall clearance W1: minimum 12".
Wall clearance W2:* minimum 12".
Wall clearance W3: Boiler length L or minimum 86".
Wall clearance W4: 36".
Note: Wall clearance W3 can be reduced to 4 feet for
assembled boilers. Boiler cleaning will now require
use of segmented brushes.
*Requires burner removal during cleaning.
