SECTON 4: INSTALLATION AND PIPING
SECTON 4.1: LOCATION OF THE TX SERIES WATER HEATER
Locate the heater so that there is easy access to the control, piping, valves, drain, and heater for future
servicing and maintenance. The heater is to be kept in an area where it is not exposed to freezing
temperatures.
Also, the heater must be located in an area where a leak (e.g. from the piping€ or fittings, from any
temperature and relief valve discharge, or from the tank itself), will not cause personal harm or damage
the surrounding area. The tank should be installed in an area with a floor drain or in a pan suitable for
water heaters.
NOTE:
DHT will not be held liable for any damages caused by water leakage.
The floor or area where the tank is installed must be capable of supporting the tank when filled with
water. (Refer to Table at right.)
FOR YOUR SAFETY:
Do not store or use gasoline or other flammable vapors or liquids in the vicinity of this or any other
appliance. Controls on this appliance could ignite vapors causing an explosion.
SECTON 4.2: PIPING INSTALLATION INSTRUCTIONS
1.
General
a.
All plumbing must be in accordance with the requirements of the authority having
jurisdiction.
b.
Use both thread tape and pipe dope on all mechanical connections.
c.
Zone valve (if used) and circulator must be sized to provide minimum flow rate specified
in the table to the right, Flow Specifications. Use 1 inch nominal copper tubing between
boiler and heat exchanger. See the tables on Friction Loss. Point of emphasis: using a
zone valve without a full bore may cause high pressure drop, which will adversely affect
performance. Use extreme care when selecting zone valve.
i.
All piping must be adequately supported.
ii.
Allow for thermal expansion.
iii.
Dielectric Unions (recommended) - used to electrically isolate the TX Series tank
from the connected domestic water piping. This helps to minimize the
possibility of corrosion damage.
