LINE VOLTAGE E19
PUMP OFF
E19 indicates the line voltage frequency is
out of range. This could happen if the boiler
is being powered from a small gasoline
powered generator that is overloaded or not
functioning correctly.
Inspect power wiring to the boiler and repair as
necessary. If connected to line voltage, notify the power
company. If connected to an alternate power source such
as a generator or inverter, make sure the line voltage
frequency supplied by the device is 60 Hz.

Part 13 - Maintenance
A. Procedures
Periodic maintenance should be performed once a year by a qualified
service technician to assure that all the equipment is operating safely
and efficiently. The owner should make necessary arrangements with
a qualified heating contractor for periodic maintenance of the boiler.
The installer must also inform the owner that a lack of proper care and
maintenance of the boiler may result in a hazardous condition.
BEFORE EACH HEATING SEASON a trained and qualified service
technician should perform the inspections as per the boiler
inspection and maintenance schedule in this manual. Failure to do
so could result in death or serious injury.
The combustion chamber insulation in this product contains ceramic
fiber material. Ceramic fibers can be converted to cristobalite in
very high temperature applications. The International Agency for
Research on Cancer (IARC) has concluded, “Crystalline silica inhaled
in the form of quartz or cristobalite from occupational sources is
carcinogenic to humans (Group 1).”
• Avoid breathing dust and contact with skin and eyes.
• Use a NIOSH certified dust respirator (N95). This type of
respirator is based on the OSHA requirements for cristobalite at
the time this document was written. Other types of respirators
may be needed depending on job site conditions. Current
NIOSH recommendations can be found on the NIOSH website:
http://www.cdc.gov/niosh/homepage.html. NIOSH approved
respirators, manufacturers, and phone numbers are also listed
on this website.
• Wear long-sleeved, loose fitting clothing, gloves, and eye
protection.
• Apply enough water to the combustion chamber lining to
prevent dust.
• Wash potentially contaminated clothes separately from other
clothing. Rinse clothes washer thoroughly.
NIOSH stated First Aid.
• Eye: Irrigate immediately.
• Breathing: Fresh air.
B. Combustion Chamber Coil Cleaning Instructions
*Before beginning this procedure, have on hand the following items:
• a nylon, stainless steel, or brass brush (not steel)
• gloves and eye protection
1. Shut down the boiler by using the following steps:
a. Close the gas valve. Shut down the unit, and wait for it to be cool
to the touch.
b. Disconnect the condensate piping from the outside connection,
(not from the boiler side), so flow from condensate reservoir can be
observed.
c. Disconnect electrical connections from the gas valve, spark
electrode, flame rectification probe, and combustion blower.
d. Remove the four (4) screws on the aluminum ¾” NPT connector
on the right side of the gas valve.
e. Disconnect the wiring connected to the combustion blower
motor.
f. Remove the six (6) 10MM nuts from the burner plate assembly.
g. Pull the entire burner plate assembly with blower still attached
towards you, while removing or pushing aside any wiring to
allow removal of the assembly.
2. Spray the coils liberally with a spray bottle filled with clear tap
water. Confine the spray to the area being cleaned. Avoid getting
the ceramic target wall wet. If the condensate system is blocked, use
a vacuum to clear it.
3. Scrub coils of any buildup with a nylon, stainless steel, or brass
brush. Do not use a steel brush. Vacuum the debris from the coils.
4. Spray the coils again with clear tap water. Confine the spray to the
area being cleaned. Flush the combustion chamber with fresh water
until it runs clear from the condensate reservoir. At this point, the
boiler should be ready to be reassembled.
a. Inspect gaskets.
b. Reinstall the burner assembly
c. Replace and tighten the six (6) 10MM nuts to the burner plate
using staggered tightening sequence. (See detail.)
d. Reconnect all wiring connections
e. Inspect the gas valve. Ensure the O-ring is in place.
f. Replace the four (4) screws on the aluminum connector on the
gas valve. Turn the gas back on. (IMPORTANT: CHECK FOR GAS
LEAKS!)
