Safety circuit wiring

Certain Vapor-logic3 alarm points are wired in series and register as

“Interlock Disable” when any of the following alarms is tripped: door

interlock, blocked flue, or low water.

Whether leaving alarm signals in series or separating them, you must

perform either the procedure at left or the procedure below.

Note: If needed, refer to the Vapor-logic3 wiring diagram and the

Vapor-logic4 Installation and Operation Manual

for more

wiring information.

below.

Note: Torque terminal block screws to 2.5 in-lb (0.28 N·m). Torque all

other terminal connections to 7 in-lb (0.79 N·m).

Door interlock switch (Figure 9-1)

1. Remove wire 414 from terminal 14 on Vapor-logic3 main board.

Remove other end of wire from position 11 on low water relay, and

keep for re-use in Step 8.

2. Remove wire 414A from position 14 on low water relay. Land this

wire at terminal 14 on Vapor-logic4 adaptor board.

3. Locate wire 415A running between door interlock switch and

blocked flue switch. Remove this wire from both termination

points, and keep for re-use in Step 5.

4. Locate wire 415 running between terminal 15 on Vapor-logic3

main board and blocked flue switch. Remove fork connector end

from blocked flue switch, and connect it to door interlock switch

where wire 415A was located.

Blocked flue switch (Figure 9-1)

5. Locate wire 415A that was removed in Step 3: Connect one fork

terminal to NC (normally closed) contact. Run wire to P3-4

connector at top of Vapor-logic4 adaptor board. Cut wire to length,

strip end, and land it at terminal P3-4.

6. Using other end of wire 415A that was removed in Step 3: Land

remaining fork terminal at the C (common) contact on blocked

flue switch. Strip other end, land it at one of the h terminals

(24Vac) on terminal strip at bottom of subpanel.

Low water circuit (Figure 9-1)

7. Locate wire 801 that runs to T1 terminal on expansion board that

was directly to the right of Vapor-logic3 main board. Remove end

of this wire, land it at position 11 on low water relay.

8. Locate wire 414 that was removed in Step 1. Land one end of this

wire at position 14 on low water relay. Land other end at terminal

P3-3 on Vapor-logic4 adaptor board.

1. Make sure gray-handled jumper supplied

with upgrade kit is inserted into terminals

P3-3 and P3-4 on Vapor-logic4 adaptor

board (Figure 8-1).

2. Locate wire 801 that runs to expansion

board terminal T1, and land it at terminal

P3-3 on Vapor-logic4 adaptor board. If

wire 801 does not reach P3-3, use a longer

18-gauge, stranded wire. Torque terminal

block screws to 2.5 in-lb (0.28 N·m).
