E. Alliance Water Heater (if used). May be used with
Intermittent Circulation only.
Refer to Alliance Installation, Operating and
Service Instructions for wiring, piping and
additional information.
F. Vent Damper Sequence of Operation. See Figure 30 for
schematic wiring diagram.
1. The Vent Damper is continuously powered at
Terminal 1.
2. When there is a call for heat, the damper relay coil
is energized through Terminal 5 if all limits ahead
of the damper are satisfied.
3. The relay coil closes contacts which energize the
damper motor, causing the damper to open.
4. When the damper blade reaches the fully open
position, power is sent back to the ignition circuit
through Terminal 2 and the damper motor is de-
energized.
5. When the call for heat is satisfied, the damper relay
coil is de-energized - closing contacts which
energize the damper motor. This causes the damper
to close. When the damper blade reaches the fully
closed position, the damper motor is de-energized.
POWER FAILURE - The damper blade will stop in
the position it was in when power failed.
(Combustion can never take place unless the
damper blade is in the fully open position.)
G. Sequence of Operation and Wiring. Refer to Table 10
for the appropriate control system.
H. Optional Low-Water Cut-Off Wiring. See Figures 45
through 48.
