NOTE: Obey all local codes. Obtain all applicable permits before
installing the boiler.
NOTE: Install all system components and piping in such a
manner that does not reduce the performance of any fire rated
assembly.
Do not use this boiler for anything other than its intended
purpose (as described in this manual). Doing so could result in
property damage and WILL VOID product warranty.
High heat sources (sources generating heat 100
greater, such as stove pipes, space heaters, etc.) may damage
plastic components of the boiler as well as plastic vent pipe
materials. Such damages ARE NOT covered by warranty. It is
recommended to keep a minimum clearance of 8" from high
heat sources. Observe heat source manufacturer instructions,
as well as local, state, provincial, and national codes, laws,
regulations and ordinances when installing this boiler and
related components near high heat sources.
Due to low water content of the boiler, improperly sizing
the boiler in regard to potable water heating load will result
in excessive boiler cycling and accelerated component
failure. Westinghouse DOES NOT warrant failures caused by
improperly sized boiler applications. DO NOT oversize the
boiler to the system. Modular boiler installations greatly reduce
the likelihood of boiler oversizing.
A. Improper Combustion
Do not obstruct the flow of combustion and ventilating air.
Adequate air is necessary for safe operation. Failure to keep the
exhaust vent and combustion air intake clear of ice, snow, or
other debris could result in property damage, serious personal
injury, or death.
B. Gas
Should overheating or gas supply fail to shut off, turn off the
manual gas control valve to the boiler.
C. When Servicing the Boiler
Be sure to disconnect electrical power before opening boiler
cabinet or performing service. Failure to do so could result in
electrical shock, property damage, serious personal injury, or
death.
To avoid electric shock, disconnect electrical supply before
performing maintenance.
NOTE: When inquiring about service or troubleshooting,
reference the model and serial numbers from the boiler rating
label.
To avoid severe burns, allow boiler and associated equipment to
cool before servicing.
D. Boiler Water
•
If you have an old system with cast iron radiators,
thoroughly flush the system (without boiler connected)
to remove sediment. The high-efficiency heat exchanger
WHL-033 Rev. 1.29.16
can be damaged by build-up or corrosion due to
sediment. Westinghouse recommends a suction
strainer in this type of system.
•
Do not use petroleum-based cleaning or sealing
compounds in boiler system. Gaskets and seals in
the system may be damaged, possibly resulting in
substantial property damage.
•
Do not use "homemade cures" or "boiler patent
medicines". Substantial property damage, damage to
boiler, and/or serious personal injury may result.
•
Continual fresh make-up water will reduce boiler life.
Mineral buildup in the heat exchanger reduces heat

transfer, overheats the stainless steel heat exchanger,
and causes failure. Addition of oxygen from make-
up water can cause internal corrosion in system
components. Leaks in the boiler or piping must be
repaired at once.
NOTE: DO NOT add cold make up water to the system when
the boiler is hot. Thermal shock can potentially cause cracks
in the heat exchanger. Such damage IS NOT covered by
warranty.
E. Freeze Protection
NOTE: Consider piping and installation when determining
boiler location.
Failure of the boiler due to freeze related damage IS NOT
covered by product warranty.
NEVER use any toxic chemical, including automotive,
standard glycol antifreeze, or ethylene glycol made for
hydronic (non-potable) systems. These chemicals can
attack gaskets and seals in water systems, are poisonous if
consumed, and can cause personal injury or death.
Part 2 - Before You Start
UNCRATING THE BOILER - Any claims for damage or
shortage in shipment must be filed immediately against the
transportation company by the consignee.
A. What's in the Box
Remove all sides of the shipping crate of the boiler.
Components included with the boiler:
• Temperature and Pressure Gauge
• Outdoor Sensor
• Three (3) Stainless Steel Screens
• Installation Manual and Warranty
• User's Information Manual
• CSD-1 Form
• H-3 Data Sheet
B. How the Boiler Operates
Condensing technology intelligently delivers highly efficient
hydronic heating while maximizing efficiency by measuring
data from the heating system. Outlined below are the features
of the system and how they operate:
