3.5 Water Connections and Piping
Systems
3.2 Setting Boiler
1. Verify the fl oor structure where the boiler will
be set can support the weight of the boiler.
2. Locate the boiler so all components are pro-
tected from water damage during operation.
3. As required, raise the boiler above the fl oor level
to reduce the risk of water damage.
4. Consult ANSI Z223.1 for garage applications.
5. Move the boiler to the installation location
with an appliance dolly capable of handling
the boiler. If required, the boiler jacket may be
removed to simplify handling.
3.3 Uncrating Boiler
1. Cut the four corners of the crate as shown in
Figure 3.
2. Lift the crate off of the boiler. See Figure 4.
3. Remove the front bottom access panel. See
Figure 5. Locate and remove the four bolts
holding the boiler to the wooden shipping base.
3.4 Leveling the Boiler
1. Place level on boiler. Adjust level of boiler by
placing shims under cast iron boiler as needed.

WARNING
!
CONTAMINATION HAZARD.
AIR IN BOILER PIPING SYSTEM LEADS TO
OXYGEN CONTAMINATING THE SYSTEM.
OXYGEN CONTAMINATION LEADS TO CORRO-
SION AND PREMATURE BOILER FAILURE. THE
BOILER STANDARD LIMITED WARRANTY DOES
NOT COVER OXYGEN CONTAMINATION OF
BOILER OR SCALE DEPOSITS CAUSED BY MAKE
UP WATER ADDED TO THE SYSTEM. FAILURE
TO FOLLOW THIS WARNING COULD RESULT
IN SERIOUS INJURY, DEATH, OR PROPERTY
DAMAGE.

CAUTION
!
If the boiler is left operational and unattended for any
extended periods of time, provisions must be taken
periodically to ensure the system operation. This is
especially important in below freezing weather. If for
any reason your boiler should fail to operate, damage
could result, such as frozen water pipes.
NOTE: Do NOT use the water system pipes to
ground electrical appliances.
NOTE: Ensure the hydronic system is properly
supported so that no stress is applied to the boiler
connections.
General Guidelines
1)
For good operation and long life of the boiler, the
piping system must be designed properly.
2) Install air vents at any points in the supply and
return pipes where air pockets could form. Also,
install a discharge device at the lowest point in the
system to allow complete draining of the system.
3) If the boiler is installed at the lowest level point
of a single loop system or hydronic coils are used
upstream of air conditioning coils, a fl ow check valve
should be installed to prevent the natural migration
of hot water through the system in the curculator's
off cycle.
