Figure 19: Factory Supplied Piping and Trim Installation
NOTICE
Failure to properly pipe boiler may result in improper operation and damage to boiler or structure.
Install boiler so that the gas ignition system components are protected from water (dripping, spraying,
rain, etc.) during appliance operation and service (circulator replacement, etc.).
Oxygen contamination of boiler water will cause corrosion of iron and steel boiler components, and
can lead to boiler failure. Crown Boiler Company’ s Standard Warranty does not cover problems
caused by oxygen contamination of boiler water or scale (lime) build-up caused by frequent addition of
water.
Do not fill boiler with softened water to prevent chloride contamination.
Installation is not complete unless a safety relief valve is installed into the tapping located on left side
of appliance or the supply piping.
Notice: Required near boiler
piping (“boiler loop piping”)
size may be larger than piping/
trim supplied with boiler. See
Table 14. If larger piping is
required, increase size directly
after supplied trim.
