Altering any Westinghouse boiler with parts not manufactured
by Westinghouse WILL INSTANTLY VOID the boiler warranty
and could result in property damage, personal injury, or death.
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
o
F / 37
o
C or
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.
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
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
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.
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 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.
Due to the low water content of the boiler, improper sizing of the
boiler with regard to heating system load will result in excessive
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.
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.
UNCRATING THE BOILER
- Any claims for damage or
shortage in shipment must be filed immediately against the
transportation company by the consignee.
Failure of the boiler due to freeze related damage IS NOT
covered by product warranty.
Part 2 - Before You Start
Remove all sides of the shipping crate of the boiler.
DO NOT USE THIS BOILER IF ANY PART HAS BEEN
SUBMERGED IN WATER.
Immediately call a qualified
service technician. The boiler MUST BE replaced if it has been
submerged. Attempting to operate a boiler that has been
submerged could create numerous harmful conditions, such as
a potential gas leakage causing a fire and/or explosion, or the
release of mold, bacteria, or other harmful particulates into
the air. Operating a previously submerged boiler could result in
property damage, severe personal injury, or death.
NOTE:
Boiler damage due to flood or submersion is considered
an Act of God, and IS NOT covered under product warranty.
label.
To avoid severe burns, allow boiler and associated equipment
to cool before servicing.
F. High Elevation Installations
Natural gas at high elevation might contain less heating
value than typical 1,000 BTU/cu ft and therefore can cause
improper air / gas mix leading to improper combustion. For
natural gas installations above 3,000 ft, call your gas provider
to determine the heating value of the supplied natural gas.
