Vitodens 100-W, B1HA series & B1KA Combi Installation/Service Safety
Important Regulatory and Installation Requirements
Codes
The installation of this unit shall be in accordance with
local codes or, in the absence of local codes, use CAN/
CSA-B149.1 or .2 Installation Codes for Gas Burning
Appliances for Canada. For U.S. installations use the
National Fuel Gas Code ANSI Z223.1. Always use latest
editions of codes.
In Canada all electrical wiring is to be done in accordance
with the latest edition of CSA C22.1 Part 1 and/or local
codes. In the U.S. use the National Electrical Code ANSI/
NFPA 70. The heating contractor must also comply with
both the Standard for Controls and Safety Devices for
Automatically Fired Boilers, ANSI/ASME CSD-1, and the
Installation Code for Hydronic Heating Systems, CSA
B214 (latest edition), where required by the authority
having jurisdiction.
Leave all literature at the installation site and advise
the system operator/ultimate owner where the
literature can be found. Contact Viessmann for
additional copies.
This product comes with several safety instruction
labels attached. Do not remove!
Contact Viessmann immediately if replacement labels
are required.
CSD-1 Field Testing of High Limit Switches for Vitodens boilers – where required by law.
VIESSMANN IS NOT RESPONSIBLE FOR ANY DAMAGES THAT THE FOLLOWING TEST PROCEDURE MAY RESULT IN
BY OVERHEATING THE SYSTEM.
The Vitodens 100/200 boilers are equipped with flow switches that when activated disable or enable the burner to
operate.
The fixed high limit, when tripped, produces a fault that will require manual reset of the boiler control.
Fixed High Limit fault simulation method #1:
Close the boiler valve and jump the flow switch.
Run the boiler at high fire and it will shut down by the coding card (in WB2B models, set coding address 06 to
max.) but should continue to stack the boiler temp until the fixed high limit is tripped.
Once the fixed high limit is tripped, slowly open the boiler valve to safely cool the boiler down.
Fixed High Limit fault simulation method #2:
Throttle the boiler valve to a point where the burner will run with as little flow as possible.
Run the boiler to high fire via relays test.
When the burner shuts down on the electronic limit, close the ball valve to stop the flow.
The boiler temp should continue to stack to trip the fixed high limit.
Once the fixed high limit is tripped, slowly open the boiler valve to safely cool the boiler down.
Fixed High Limit fault simulation method #3:
Remove one of the wires connected to limit switch, this will produce a fault in the boilers control that requires
manual reset.
