2.1 Explanations.
VGH = Condensing Boiler
DHW = Domestic Hot Water
CH = Central Heating (for central heating purposes and/or indirect hot water)
PB = display board/ control panel (Pixel But ton)
299/399/500 = Model number of the boiler.
Pump = Circulator (Sometimes, in the software e.g., the word “pump” is used, this is a circulator).
2.2 Maintenance and inspection
Maintenance and inspection of the boiler must be carried out at the following occasions:
• When a number of similar error codes and/or lock-outs appear.
• At least every 12 months maintenance must be done to ensure safe and efficient operation.
Dama
e caused by lack of maintenance will not be covered under warranty
O
N A CONTINUOUS BASIS
Do not store or use flammable vapors or liquids, such as gasoline, in the vicinity of the boiler.
Do not store or use in the boiler room and keep the boiler area free from the following items
Spray cans containing chloro-/fluorocarbons
Ammonium and/or ammonium solutions
Permanent wave solutions (hair product)
Chlorinate d waxes and/or cleaners
Swimming pool chemicals based on chlorin e
Calcium chloride used for thawing
Sodium chloride used for water softening

Cements and glues
Antistatic fabric softeners used in clothes dryers
Chlorine-type bleaches, detergents, and cleaning solvents
found in household laundry rooms
Adhesives used to fasten building products and other similar products
Do not expose the boiler to dust from construction or woodworking
O
N A MONTHLY BASIS
Visually inspect the venting system for proper size and horizontal pitch and determine there is no
blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe
condition.
Inspect around the exhaust vent and air inlet terminations outside the home for obstructions.
Keep area cl ear of snow and debris. Inspect also for any gaps at the wall penetration(s) whic h
could allow vented gasses to reenter the home.
Visually inspect water and gas pipes for leaks.
Visually inspect to see that the condensate trap not blocked and is filled with water.
If there is a condensate neutralizer installed check to see if it has neutralizing media in it.
Inspect the pressure reflief valve for signs of leakage
If any problems are found during inspection notify a qualified service technician

2.3 For installations in the Commonwealth of Massachusetts.
The following local requirements apply in addition to all other applicable NFPA requirements:
For direct- vent boilers, mechanical-vent heating appliances or domestic hot water equipment, where the bottom
of the vent terminal and the intake is installed below four feet above grade the following requirements must comply:
1) If not present on each floor level where there are bedrooms, a carbon monoxide detector and alarm must
be placed in a living area outside the bedrooms. The carbon monoxide detector and alarm must comply
with NFPA 720 (2005 Edition).
2) A carbon monoxide detector and alarm shall be located in the room that houses the boiler and/or
equipment and shall:

installation instructions shall remain with the boiler and/or equipment at t he completion of the instal lation.
4) A metal or plastic identification plate shall be mounted at the exterior of the building, four feet directly above
the location of vent terminal. The plate shall be of sufficient size to be easily read from a distance of eight
feet away, and read “Gas Vent Directly Below”.
For direct-vent boilers mechanical-vent heating boilers or domestic hot water equipment where the bottom of the
vent terminal and the intake is installed higher than four feet above grade the following requirements must comply:

5.4 Boiler History
The boiler history (found in the information menu) displays several history counters that keep track of the boiler
usage. The following boiler history data is available:
(Sub) Menu item Description
Successful Ignitions Number of successful ignitions.
Failed Ignitions Number of failed ignitions.
Flame Failures Number of flame failures (loss of flame).
Operation Da ys Number of days that the appliance is operational (powered ON).
CH Burner Hours Number of hours that the appliance has burned for Central Heating.
DHW Burner Hours Number of hours tha t the appliance has burned for Domestic Hot Water.
5.5 Error logging
Errors will be logged for a stand-alone system or for a complete cascade system (based on the cascade settings). The display will monitor the error number(s) it receives from the boiler(s): new errors will be stored in
the error log.
An error will be logged with a (Real Time Clock) time stamp (date and time) when the error was detected and
a boiler ID of the boil er on which the erro r was d et ected.
Note: the error log is a completely different error logging mechanism than the one used by the burner control
itself. Therefore, the error log is different from the (internal) error history of the burner control.
The error log can be seen from the error log menu, which is located in the Information menu. In the Error log
menu the following options can be selected:
(Sub) Menu item Description
Error Log Show the error log (based on the selected filter options)
Filter Error Type Filter errors based on the Error type (lockout/blocking)
Filter Boiler ID (Cascade Syst em only) Filter errors based on Boiler ID (Managing, Dep 1, Dep2, etc.)
Clear Error Log Clear the error log (protect ed by passwo r d )
When no filtering op tion is sel ected (disabled) the error log will show all er rors for tha t category. So, if both filters
are disabled, the error log will show all the errors in the log.

- The selected error index from the total numbers of errors in the (filtered) error log
5.6 Service reminder
The Service reminder will remind the owner/user of the appliance to service the appliance every 2000 burn
hours. When service is not done within this time, a message will be shown on the screen: "Service is required!",
alternating with the normal status display.
NOTE: with the message "Service is required" the boiler keeps running , but maintenance must b e done before
resetting this message.
When the Service reminder has become active, the time it takes before service is actually done is being logged
(in hours). This time is called the Service Overdue Time.
The Service reminder can be reset by the installer who services the appliance.
Service status information can be viewed: Menu/ Information/ Service:
(Sub) Menu item Description
Service history View the Service history (log). For each service moment the Service overdue counter is stored. When the
overdue counter is 0 hrs, it means service was done before the Service reminder was active. The log is ordered
so the most recent service moment is shown first (on top of the list).
Burn hours since last service
Burn hours till service Shows the number of burn hours until service is required.
Reset service reminder Reset the Service reminder (and store Ser vice o ver du e cou nter in the service history).
Shows the number of burn ho urs since the last service moment.
Installer must enter the installer pas swor d fir st befor e it can be reset.
5.7 System test
For testing the system at fixed power rates a system test can be activated via the menu. Via the system test the
boiler can be started without CH or DHW being present. The system test has priority.
The following modes are available:
System test mode Description
0 (Not active) System test mode not active
