Part 2 - Maintenance; Service Technician - Westinghouse WBRU 100W Series User's Information Manual

Ensure each zone valve connected to the boiler is open while the boiler is operating. Doing so ensures proper heating system
operation.
DO NOT wipe the boiler or control panel with a wet cloth. Doing so may result in an electric shock, substantial property damage,
premature boiler failure, severe personal injury, or death.
Hydronic systems that use glycol as heat transfer fluid must be serviced periodically. Glycol can break down over time, become acidic,
and attack gaskets and seals in boilers. This can result in property damage, severe personal injury, or death.
Each glycol manufacturer has different recommendations for testing and replacement. Do not test glycol quality yourself. Have your
qualified service technician check glycol quality during annual servicing. If you are unsure when your glycol was last tested, call a
qualified service technician to test and replace glycol, if necessary.
If the boiler is not to be used for an extended period of time during freezing conditions, consider shutting down the system and draining
it of water. Shut off the gas and cold water supply valves.
DO NOT attempt to disassemble this boiler. Doing so could result in improper boiler operation or premature boiler failure, substantial
property damage, and/or severe personal injury or death due to electric shock, fire, or explosion. If repairs are required, contact a
qualified service technician.
DO NOT touch the exhaust vent pipe. Doing so could result in substantial personal injury.
Be careful when opening a hot water faucet or draining
water from the boiler. Water temperature over 125
instantly cause severe burns, or death, from scalds.
Children, disabled, and elderly are at the highest risk of
being scalded. See instruction manual before setting
temperature at boiler. Feel water before bathing or
showering!
