MAINTENANCE
d. Connect the wires to the blocked condensate
float switch in the lid of the condensate collector.
e. Fill the condensate neutralizer container with 1-2
inches of neutralizing media.
4. Restarting the Boiler:
a. Open the manual gas valve at the rear of the
boiler.
b. Turn both burner service switches on.
c. Observe the boiler function to make sure you see
condensate flow.
d. If no flow of condensate is evident, repeat this
procedure.
5. If the problem persists it is possible that there
is a problem with material deposits in the heat
exchanger. Follow the Combustion Chamber Coil
Cleaning Instructions in this section.
E. 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 boiler down and access the heat exchanger
using the following steps:
a. Close the manual gas shutoff valve and wait for
the unit to be cool to the touch.
b. Disconnect the condensate piping from the
outside connections (not from the
P
ure
F
ire
®
side)
so the flow can be observed.
c. Disconnect compression nut on gas valve inlet
and disconnect the gas valve electrical connector.
d. Remove the six 10 mm nuts from the burner
plate assembly. Disconnect wire leads to the
spark igniter and flame sensor. Disconnect two
Molex plugs from blower motor.
e. Pull the entire burner plate towards you to access
the heat exchanger coils.
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
debris from the coils.
4. Spray coils with clear water, making sure to confine
the spray to the area being cleaned (try to avoid
wetting the back ceramic wall of the unit). Flush the
combustion chamber with fresh water. At this point,
the
P
ure
F
ire
®
should be ready to power back up.
5. Reinstall the burner plate assembly using the
following steps:
a. Inspect the inside of the heat exchanger for dirt
and debris.
b. Install the burner plate assembly and replace the
six 10 mm nuts.
c. Reconnect the wire leads to the spark igniter,
flame sensor and gas valve. (Be sure that the
spark igniter is connected to the lead with the
large insulated connection boot.) Reconnect two
Molex plugs on blower motor.
d. Connect the compression nut on the gas valve
inlet and reattach the gas valve electrical
connector.
e. Reset thermostats.
(IMPORTANT: BE SURE
THAT THE VENT CONNECTION IS NOT
BLOCKED.)
f. Turn the power to the
P
ure
F
ire
®
on. Observe the
display module to assure proper operation.
g. Initiate a call for heat** and observe the
condensate flow.
h. Reconnect the condensate piping to the drain
connection.
**NOTE: When firing the boiler the first
few times you may experience some
fluttering of the gas burner that may result
in a flame lockout. This is normal and will
require you to recycle the unit until this
clears up. This is caused by water still
present in the combustion chamber.
6. Inspect exhaust vent and air intake vents for proper
support and joint integrity. Repair as necessary.
Refer to Section 5, VENTING.
7. Inspect exhaust vent and air intake vent terminations
for obstructions or corrosion. Corrosion is an
indication of exhaust gas recirculation.
It is extremely important to check for leaks when
reconnecting the gas valve. Failure to do so may
result in severe personal injury, death or major
property damage.
WARNING
Leaks in the vent system will cause products of
combustion to enter structure (vent system operates
under positive pressure).
