Utica Boilers SW Series II 安装指导
6
1.
Typical installation using circulators shown in Figure
1.
2.
Typical installation using zone valves shown in Figure
2.
3.
Hot water boilers installed above radiation level must
be provided with low water device either as part of
boiler or at time of boiler installation.
4.
When boiler is connected to heating system utilizing
multiple zoned circulators, each circulator must be
supplied with fl ow control valve to prevent gravity
circulation.
• Reduced pressure back fl ow preventer must be
present under provisions required by Environmental
Protection Agency (EPA).
5.
Bypass piping is an option which gives ability to adjust
supply boiler water temperature to fi t system or
condition of installation. This method of piping is not
typically required for baseboard heating systems.
CONNECTING SUPPLY AND RETURN PIPING
• Method used to protect systems using radiant
panels and material they are encased in from high
temperature supply water from boiler. See Figure
3.
• Method used to protect boilers from condensate
forming due to low temperature return water.
Generally noticed in large converted gravity systems
or other large water volume systems. See Figure 4.
• Method used to protect boilers from condensate
forming as well as protecting heating system from
high water temperature. See Figure 5.
high water temperature. See Figure 5.
6.
When using bypass piping, adjust valves A and B until
desired system temperature is obtained.
7.
Bypass loop piping must be same size piping for supply
and return.
8.
Connect supply and return piping as suggested in
Figure 6, when boiler is used in connection with
refrigerated systems:
