Shut-Off Valves; Filters; Thermostatic Valves; Thermostatic Valve Exemption - Central Boiler e-Classic 1450 IR Owner's Manual

Shut-Off Valves

Shut-off valves should be installed on both sides of each
pump so if it becomes necessary to repair or replace the
pump, the pump can be isolated (see Fig. 9).

Filters

A Y-strainer or filter may be installed at the outlet side
of the pump to remove foreign particles which may be
present in the water. Always install Y-strainers with the
cleanout in the lowest position.

Thermostatic Valves

NOTE: A 3/4" thermostatic valve with installation
instructions is included with each new E-Classic
1450 and must be installed on each set of supply
and return lines or warranty can be voided.
NOTE: For additional thermostatic valves, or
for 1-1/4" thermostatic valves, contact your
authorized Central Boiler dealer.
NOTE: The thermostatic
throughout the manual may vary from your
installation. See the installation instructions
provided with the thermostatic valve.
14
A thermostatic valve must be installed on each set
of supply and return lines in the system to maintain
the outdoor furnace water temperature above 150˚F
(65˚C). Operating the outdoor furnace with the water
temperature less than 150˚F (65˚C) may result in more
condensation in the firebox that can lead to corrosion.
It is recommended that the water temperature setpoint
of the furnace be set to 185˚F (85˚C) to decrease the
likelihood of the water temperature falling to 150˚F
(65˚C). As a result, the outdoor furnace will operate
with a greater efficiency and require less maintenance.
Failure to follow proper operating instructions may
result in furnace damage.

Thermostatic Valve Exemption

If the system includes more than one building and one of
the buildings is heated with an oil, gas or electric boiler
that also serves as a backup for the other building(s)
by keeping the system water temperature above 150˚F
(65˚C) when the outdoor wood furnace is not fired, the
thermostatic valve is not required.
