Lochinvar SDT/SET065 - 119 2Pre-installation, Locating the Tank, Recommended Clearances

2Pre-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

SDT/SET Installation & Operation Manual

Locating the Tank

1.Choose a location for your water heater centralized to the piping system. You must also locate the SDT/SET 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 (page 7)- Pressure Drop Values, through the coil. 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, electrical, and servicing clearances must be figured when locating the water heater.

Minimum Clearance to the Element Cover

See FIG 2-1. Clearances must be a minimum of 24-inches to allow for element removal and replacement on SET model.
