Wiring a system circulator

1.  For combined systems, to activate a system circu-

lator when the Boiler circulator operates, wire as

shown at bottom of Figure 1, page 0.

2.  You must install a relay as shown. DO NOT wire in

parallel with the Boiler circulator. See

in

Figure 1.

Routing line voltage wiring

1.  Route line voltage connections to the jacket open-

ings shown in Figure 18.

Low voltage connections 

(Fig. 18)

1.  Connect low voltage wiring to low voltage termi-

nal strip (Figure 19, page 2, item 1) as shown in

Figure 19 and the boiler wiring diagram.

2.  Route  all  low  voltage  wires  through  grommeted

jacket opening to right of low voltage terminal strip,

as shown in Figure 18.

Room thermostat 

(space heating)

1.  For combined space heating/water heating systems,

connect Figure 19, item 2, room thermostat or end

switch (isolated contact only) between terminals 
and .

2.  Install thermostat on inside wall away from influ-

ences  of  drafts,  hot  or  cold  water  pipes,  lighting

fixtures, television, sunrays, or fireplaces.

.  Thermostat anticipator (if applicable):

a.  If connected directly to boiler, set for 0.1 amps.
b.  If connected to relays or other devices, set to match

total  electrical  power  requirements  of  connected
devices. See device manufacturers’ specifications and
thermostat instructions for details.

Outdoor temperature sensor

1.  Outdoor reset operation applies only to combined

space heating/water heating systems.

2.  Connect  outdoor  temperature  sensor  (Figure 19,

item ) between terminals 1 and 2 to enable out-

door  reset  operation  of  the

 Gasboiler.  If

fixed-temperature  operation  is  required,  do  not

install outdoor sensor.

.  Mount sensor on exterior wall, shielded from di-

rect sunlight or flow of heat or cooling from other

sources.

.  Install a summer/winter switch (Figure 19, item )

across terminals 1 and 2 to force fixed-temperature

operation  during  summer  months.  (When  the

switch  is  closed,  boiler  will  attempt  to  maintain

constant temperature.)

.  Route sensor wires through the grommeted hole at

right of the electrical entrance (see Figure 18).

Water heater thermostat

1.  Connect  PLUS  water  heater  aquastat  terminals

“C”  and “1”  to

 Gas  boiler  low  voltage  ter-

minal  strip  between  terminals    and   (Figure 9,

item ).

Additional limits

1.  Connect  additional  limit  controls  and  interlocks

between the terminals shown in Figure 19.

2.  Controls  connected  between  terminals    and  

(see  Figure 19,  item  )  will  cause  a  soft  lockout

(automatic reset). When limit(s) closes, boiler will

resume normal operation.

.  Controls  connected  between  terminals    and  8

(see Figure 19, item ). will cause a hard lockout

(manual  reset).  The  boiler  will  only  restart  after

the Ultra display panel RESET switch is pressed.
