Installation & Operation Manual

2  

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.  Be certain the domestic water supply to the tank has 
 

physical and chemical characteristics that fall within 

 

the limits shown in Table 2A. Where questions exist 

 

as to the composition of the water on the job, a 

 

qualified water treatment expert should be consulted.

Water with characteristics outside the 
limits shown in Table 2A may severely 
shorten the life of the tank due to 
corrosion.  Damage to tanks in such 
cases is not covered under warranty.

3.  Read and understand all installation requirements in 
 this 

manual.

Table 2A

Water Chemistry Requirements

Water used in the tank must have characteristics falling 
within the following limits:

Characteristic

Min.

Max.

Ph

6.0

8.0

Chloride (PPM)

--

80

 

CAUTION

Locating the tank

1.  Choose a location for your water heater centralized to the 
 

piping system.  You must also locate the SIT DW water heater 

 

where it will not be exposed to freezing temperatures. 

 

 

Additionally, you will need to place the water heater so that 

 

the controls, drain, and inlet/outlets are easily accessible.  

 

This appliance must not be installed outdoors, as it is 

 

certified as an indoor appliance, and must also be kept 

 

vertical on a level surface.

2.  Keep distance between boiler and water heater to a 
 minimum 

to:

 

 

a.  reduce piping heat loss

 

 

b.  provide minimal friction loss

3.  Figure 1-1 on page 4 shows the weights of all the tanks filled 
 

with water.  Make sure that the location chosen for the tank 

 

is capable of supporting it.

This appliance 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 water heater should always 
be located in an area with a floor drain or 
installed in a drain pan suitable for water 
heaters.  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

4.  The tank may be located some distance from the boiler 
 

provided the pump is designed to provide the flow 

 

called for in Table 3B - Pressure Drop Values, through 

 

the coil.  Also, the further the tank is from the boiler, the 

 

longer the response of the boiler will be to a call from the 

 

tank zone.  Insulate piping between the boiler and the tank.

Recommended clearances

The installation location must provide adequate clearances 
for servicing and proper operation of the water heater.  A 12 
inch vertical clearance is recommended from the top of the 
water heater.  A zero clearance is allowed for the sides of the 
water heater.  However, boiler and servicing clearances must be 
figured when locating the water heater.
