C. LOCATING THE WATER HEATER
This water heater is certified for indoor use only. DO NOT INSTALL OUTDOORS. Outdoor installations ARE NOT covered by warranty.
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. HTP
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.
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.
