WATERPROOF (OUTDOOR) BOILER ASSEMBLY AND PIPING
1. Place boiler at a location as centralized as
possible with the piping system and as free from
unusual wind currents as possible.
2. A level concrete or noncombustible base is
recommended with the top high enough so that
ground water and melted snow will not rise as high
as the bottom of the boiler. It is also recommended
that crushed stone or gravel surround the base to
keep shrubbery, weeds and grass at least 18” from
the boiler.
3. If necessary, level boiler with shims placed
beneath feet.
4. Accessibility clearances must take precedence
over fire protection clearances. Allow at least 24”
for servicing at the front and burner sides of the
boiler. Allow at least 18” at a side where passage is
required to another side for servicing. A 6” clearance
from combustible material on all sides and the top
is recommended.
5. Advise owner to maintain air passages free from
obstructions. Ventilating and combustion air must
enter boiler casing without restrictions.
2. Circulator, make-up water, expansion tank, etc.,
should be installed at a convenient location inside
the building.
a. Domestic Water Heating: See Figure 14
for piping of remote (indoor) tankless coil or
indirect water heater. An indirect Water Heater
is recommended.
b. Without Domestic Water Heating: See
Figure #9 .
3. Place control well in top ¾” tapping near burner
end of boiler.
4. Install a ¾” street ell in remaining top tapping.
Mount relief valve on street ell using a ¾” x 7” nipple.
Mount ¾” overflow pipe (not supplied) so that it
extends downward beside boiler casting and will be
covered by boiler jacket when jacket is in place. Do
not extend overflow pipe so near the ground that it
might become clogged with snow or ice.
5. At burner end of boiler mount theraltimeter with
1½” x ½” bushing in upper right 1½” tapping.
6. Install boiler drain with bushing in lower left 1½”
tapping.
ALTERNATIVE AIR ELIMINATION METHOD
WATERPROOF (OUTDOOR) BOILER LOCATING THE BOILER
1. Install 1½” nipples (not supplied) or smaller
nipples with bushings in the two tappings in end
of boiler opposite burner. These will provide feed
to the radiation and return to the boiler. Supply
pipe should be level or rise slightly toward air vent
inside building. See Figure #8 for alternative air
elimination method.
