Check the following:

1. Space

heating:

a. Make sure thermostat is calling for heat and contacts (in-

cluding appropriate zone controls) are closed.

b. Check for 24VAC between thermostat wire nuts and

ground.

2. DHW:

a. Make sure tank aquastat is calling for heat.

3. BMS

systems:

a. Make sure the BMS is calling for heat.

4. Make sure all external limit controls are either installed (and

closed) or temporarily jumpered for testing.

5. Make sure that connectors to the control module are securely

plugged in at module and originating controls and harness
connectors.

6. Gas pressure must be as specified on page 47. Make sure gas

pressure switches are not tripped.

Always check Control module fuses

ALWAYS check control module fuses before replacing
control module or any major components (blower,
etc.). If one of these fuses is blown, it can prevent
control module or other components from operating.

1. Turn OFF power to boiler at external line switch.

2. Access the control box

:

a. Remove the top front slate-colored panel.
b. Slide the glossy black panel up into its alternate position.
c. Remove the two (2) screws securing the middle slate-

colored panel and remove the panel.

d. Remove the three (3) screws securing the control box cover.

Control module fuses

1. Remove and inspect the two (2) Control fuses and the Expan-

sion module fuse (located as shown below).

2. If necessary, replace the fuse:

a. Item 1 – Low voltage circuit fuse is a 3-amp fast-blow.
b. Item 2 – Line voltage circuit fuse is a 12-amp fast-blow.

Expansion module fuse

Do not jumper fuse or replace with any fuse except as

specified. Failure to comply could result in severe per-
sonal injury, death or substantial property damage.

Circulator and Blower Fuse

1. Remove and inspect the BOILER CIRCULATOR fuses and the

BLOWER fuse (located as shown below).

2. If necessary, replace the fuse:

a.  Item 3 (tan)– Line voltage circuit fuse is a 16-amp slow-blow.
b.  Item 4 (black)– Line voltage circuit fuse is a 20-amp slow-blow.
c.  Item 5 (black,red & blue)– Line voltage circuit fuse is a 12.5-

amp slow-blow.

3. Re-install jacket panels:

a. Re-install the control box cover and tighten the three (3)

screws to secure the panel.

b. Re-install the middle slate-colored panel and tighten the two

(2) screws to secure the panel.

c. Slide the glossy black panel down into position.
d. Re-install the top slate-colored panel.

4. Restore power to boiler at external line switch and verify boiler

operation after completing boiler service.

Checking temperature sensors

1. The boiler temperature sensors (flue, outdoor, boiler in, boiler out,

return and system) are all resistance-type devices.

2. Figure 100, page 101 shows the correct value for the sensor at vari-

ous temperatures.

3. Use the resistance values at 32°F, 60°F, 70°F and 212°F to measure

the sensor resistance at known temperatures (freezing point, room
temperature and sea level boiling point). For freezing point and
