4. Peerless Partner(s) may be located adjacent to boiler to reduce piping heat loss or central to points of use to

reduce response time to fixtures.

a. Install indoors in an area not exposed to freezing temperatures. Do not install outdoors.

b. Position with adequate clearance for service and maintenance. Provide access to thermostat, temperature

and pressure relief valve, and drain valve.

c. Protect surrounding area and lower floors from damage due to leakage from temperature and pressure

relief valve, drain valve, boiler or domestic water piping, and tank. Locate water heater near a floor drain or
in a drain pan suitable for the capacity of the water heater.

d. Install on level surface. Water heater must be kept in vertical position.

5. Suggested equipment list. See PIPING for additional information.

a. Water Heater Thermostat: Provided.

b. Temperature and Pressure Relief Valve: Provided.

c. Brass Drain Valve: 1 per water heater.

d. Brass Tee’s: 2 per water heater.

e. Heat Exchanger to Boiler Piping: 1 inch nominal copper tubing and fittings. Circulator and flow control

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 speci-
fied in Table 4. Use 1 inch nominal copper
tubing between boiler and Peerless Partner
heat exchanger. See Table 5 and Table 6 for
sizing. 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.

All piping must be adequately supported.
Allow for thermal expansion.

d. High temperatures will damage plastic jack-

et. Use heat shield when soldering piping
near tank.
