2Pre-installation
1.The installation must conform with the instructions in this manual and all applicable local, state, provincial, and national codes, laws, regulations, and ordinances. Installations in Canada must conform to B149.1 or B149.2 Installation Codes.
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.Figure
WARNING Failure to properly support the tank could result in property damage or personal injury.
2.Locate the system in a location where a leak in the tank, the adjacent piping, or an open T & P valve will not damage the surrounding structure. If the area around the desired tank location is highly susceptible to water damage, install the tank in a pan with a drain.
3.The tank may be located some distance from the boiler provided the zone system is designed to provide the flow called for in Table 3A - 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.
