Pre-installation
1. The installation must conform to the instructions in this
manual and all applicable local, state, provincial, and
national codes, laws, regulations, and ordinances.
Installations in Canada must conform to B149.2 Installation
Code.
2. If the heat source water contains antifreeze, a maximum
50/50 mixture of inhibited propylene glycol is recommended.
The heat source water, including additives, must be
non-toxic, having a toxicity rating or class of 1, as listed in
the
Clinical Toxicology of Commercial Products
.
3. Read and understand all installation requirements in
this
manual.

Locating the Tank
1. Choose a location for the Thermal-Stor centralized to
the piping system. You must also locate the Thermal-Stor
where it will not be exposed to freezing temperatures.
Additionally, you will need to place the tank so that
the controls, drain, and inlet/outlets are easily accessible.
This tank must not be installed outdoors, as it is
certified as an indoor appliance, and must be kept vertical
on a level surface.
2. Table 1C on page 5 shows the weight of all the tanks filled
with water. Ensure that the location chosen for the tank
is capable of supporting the weight.
This tank must be placed where leakage
from the relief valve, leakage from the
related piping, or leakage from the tank
or connections, will not result in damage
to the surrounding areas, or to the lower
floors of the building. A tank should always
be located in an area with a floor drain or
installed in a drain pan suitable for tanks.
Lochinvar shall not be held liable for any
such water damage.
CAUTION
Failure to properly support the tank could
result in property damage or personal
injury.
WARNING
Recommended Clearances
The installation location must provide adequate clearances
for servicing and proper operation of the appliance.
A 12-inch vertical clearance is recommended from the top of
the appliance. A zero clearance is allowed for the sides of the
appliance. However, boiler and servicing clearances must be
figured when locating the appliance.
3. The tank may be located some distance from the heat
source provided that the pump is designed to provide
enough flow for both units to perform properly. The
further the distance from the tank to the heat source, the
longer the response time will be to provide sufficient heat
to the tank. Insulate piping between the heat source and
the
tank.
WARNING
Do not use automotive, ethylene glycol or
petroleum-based antifreeze. Do not use
any undiluted antifreeze. This can cause
severe personal injury, death, or substantial
property damage.
