d. Disconnect the white, red, blue, and black
connection from the Molex on the
combustion blower. (Refer to Control
Wiring Schematic, Figure 6.3.) This will
cause the fan to run at 100% which will
then blow out any sediment that has
accumulated in the condensate line. (This
process should only take a few minutes.)
e. The unit should now be ready to restart.
2. Before restarting the Pinnacle follow the
steps below:
a. Reconnect the Molex connection and
unblock the vent. (IMPORTANT: MAKE
SURE EXHAUST VENT IS NO
LONGER BLOCKED!)
b. Open the manual gas shutoff valve and
reset the thermostats.
c. Observe the boiler function to make sure
you see a condensate flow.
d. If you do not observe a condensate flow,
repeat the above procedure.
3. If the problem is not corrected at this point, it
is possible that there is a material deposit
problem. Follow the Coil Cleaning instructions
(Section b) included in this section to dissolve
deposits and clean condensate line.
b. COMBUSTION CHAMBER COIL CLEANING
INSTRUCTIONS
Before beginning this procedure, you must have
on hand the following items:
– a nylon or brass brush (not steel)
– "Rydlyme" (recommended for best results)
(available online www.rydlyme.com) or
"CLR" (available at most hardware stores)
1. Shut the Pinnacle down by using the
following steps:
a. Close the manual gas shutoff valve, shut
down the unit and wait for the unit to be
cool to the touch.
b. Disconnect the condensate piping from the
outside connections (not from the Pinnacle
side) so the flow can be observed.
c. Remove the (4) screws on the 1/2" NPT
connector on the gas valve.
d. Remove the (6) 10mm nuts from the
burner plate assembly to access the coils.
e. Pull the entire burner plate assembly
towards you, while removing or pushing
aside any wiring to allow the removal of
the assembly.
2. Using a spray bottle filled with the
recommended product "Rydlyme" or "CLR",
spray liberally on the coils, making sure the
solution penetrates and funnels down through
the condensate hose. If the condensate hose
is blocked, let the chemical penetrate for at
least 15 minutes or until it drains.
3. Use the nylon or brass brush (do not use
steel) and scrub coils to remove any buildup,
then vacuum the derbis from the coils.
4. Spray the coils with clear water, making sure
to confine the spray to the area being cleaned
(try to avoid betting the back ceramic wall of
the unit wet). Flush the combustion chamber
with fresh water. At this point, the Pinnacle
should be ready to power back up.
5. Before powering up the Pinnacle follow the
steps below:
a. Reinstall the burner assembly.
b. Replace the (6) 10mm nuts to the burner
plate.
c. Reconnect the wiring.
d. Replace the (4) screws on the 1/2" NPT
connector on the gas valve. Turn the gas
back on. (IMPORTANT: CHECK FOR
GAS LEAKS)
It is extremely important to make sure the exhaust
vent is not longer blocked. Failure to do so may
result in personal injury or death.
