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.

CAUTION

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

Installation & Operation Manual

Locating the tank

1.Choose a location for your water heater centralized to the piping system. You must also locate the SIT 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.

CAUTION

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.

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.

￿WARNING Failure to properly support the tank could result in property damage or personal injury.

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.
