Choose a location for the water heater as centralized to the piping system as possible. Also, locate the water heater and domestic
water piping where it will not be exposed to freezing temperatures. All piping should be insulated. Additionally, place the water heater
so that the drain, controls, and inlets/outlets are easily accessible.
Locate the water heater where any leakage from the relief valve, related piping, tank, or connections will not result in damage to
surrounding areas or lower floors of the building. The water heater should be located near a floor drain, or installed in a drain pan.
Westinghouse will NOT be held liable for leakage damages.
NOTE: To save on heating costs and improve energy efficiency, keep the distance between the boiler and water heater to a minimum
to reduce heat loss from excess piping and keep friction loss to a minimum. Ensure all piping between the boiler and water heater is
properly insulated to minimize heat loss.
The water heater may be located some distance from the boiler provided the circulator meets flow requirements through the coil. The
greater the distance from the water heater to the boiler, the longer the response will be to a call for domestic hot water.
o
DO NOT install this water heater in close proximity to high heat sources (temperatures greater than 100
F, such as boiler flue pipes,
ducting, etc.). Doing so could result in damages to the water heater. Such damages ARE NOT covered by warranty. Westinghouse
recommends a clearance of at least 6" from the water heater to high heat sources.
This water heater must be installed vertical on a level surface.
Ensure water heater location can support the entire filled weight of the tank. Failure to properly support the tank could result in property
damage, serious personal injury, or death.
Figure 2 – Recommended Service Clearances
NOTE: If you do not provide the minimum clearances shown in Figure 2, it might not be possible to service the heater without removing
it from the space.
This water heater must not be located near flammable liquids such as gasoline, butane, liquefied propane, adhesives, solvents, paint
thinners, etc., as the controls of this water heater could ignite these vapors and cause an explosion, resulting in property damage,
severe personal injury, or death.
B. WATER CHEMISTRY REQUIREMENTS
Chemical imbalance of the water supply may affect efficiency and cause severe damage to the water heater and associated equipment.
Westinghouse recommends having water quality professionally analyzed to determine whether it is necessary to install a water
softener. It is important that the water chemistry on both the domestic hot water and central heating sides are checked before installing
the water heater, as water quality will affect the reliability of the system. Failure of a water heater due to lime scale build-up, low pH, or
other chemical imbalance IS NOT covered by the warranty.
