PROBLEM
POSSIBLE CAUSES
POSSIBLE REMEDIES
No electrical power
to the boiler
1. Is the plug on the power supply cord unplugged
from the electrical outlet?
2. Is electrical panel’s 10 Amp circuit breaker tripped?
3. Is the fuse on the circuit board good?
4. Is there a power outage to the home?
1. Reset the plug.
2. Reset the circuit breaker.
3. If the display panel is blank, unplug the unit or
contact an authorized service technician.
4. Contact the power company.
A fan can be heard
even when the unit is
not operating.
1. The fan continues to operate after the burner shuts
off to clear the exhaust vent of combustion gases.
2. The fan may run to help prevent freezing.
1. This is normal operation
– no action is required.
2. Protect the boiler from freezing temperatures or
shut off and drain the unit.
White “smoke” can
be seen coming out
of the exterior
exhaust gas vent.
Depending on the outside temperature, water vapor
can be produced as the exhaust is vented.
This is normal operation
– no action is required.
No domestic hot
water
Is the indirect water temperature set too low?
Adjust the temperature setting.
Domestic hot water
is too hot
Is the indirect water temperature set too high?
Adjust the temperature setting.
House is not heating
up
Is the CH temperature set too low?
Adjust the temperature setting.

PART 14 – ANNUAL MAINTENANCE PROCEDURES
The boiler must be inspected and serviced annually, preferably at the start of the heating season, by a qualified service technician. In
addition, the maintenance and care of the boiler as outlined in this manual must be performed by the user/owner to assure maximum
efficiency and reliability. Follow the maintenance procedures given throughout this manual. Failure to perform the service and
maintenance or follow the directions in this manual could damage the boiler or system components, resulting in substantial property
damage, severe personal injury, or death.
Check the Surrounding Area
To prevent the potential of substantial property damage, severe personal injury, or death, eliminate all the materials listed in Table 7
from the area surrounding the boiler and the vicinity of the combustion air intake. If contaminates are found:
Remove products immediately from area.
If contaminates have been there for an extended period, call a qualified service technician to inspect the boiler for possible
damage from acid corrosion.
If products cannot be removed, immediately call a qualified service technician to re-pipe the combustion air intake piping away from the
contaminated areas.
Combustible/Flammable Materials
Do not store combustible materials, gasoline, or other flammable vapors or liquids near the boiler. If found, remove these materials
immediately.
Air Contaminates
If allowed to contaminate combustion air, products containing chlorine or fluorine will produce acidic condensate that will cause
significant damage to the boiler. Read the list of potential contaminates and areas likely to have these contaminates in Table 7. If any of
these contaminates are in the room where the boiler is located, or combustion air is taken from one of the areas listed, the
contaminates must be removed immediately or the intake pipe must be relocated to another area.
Ensure the Boiler Cabinet is Closed
Ensure the boiler cabinet is closed. Tighten the two upper and lower screws to secure it. The cabinet must be closed while the boiler is
running.
Check the Power Source
Make sure the power cord is properly connected. The main power line is connected to the manual switch box inside the boiler.
Check the Status of the Control Panel
Observe the Control Panel to ensure the boiler is powered on, and to check for any error codes. Clear any debris from the panel.
