Recommendations
* System
leaks may not always
be visible. An unseen
system
leak will become
obvious
if boiler pressure
decreases
when
make up valve is closed.
* All system
leaks must be repaired
immediately.
Constant
in-
troduction
of make up water will introduce
dissolved
oxygen,
resulting
in accelerated
boiler corrosion.
Water Chemistrv
L.
* This boiler is designed
for a closed
loop hydronic
heat sys-
tem ONLY! This boiler is not suitable
for natural gravity type
installations,
or any other open type system.
* System fluid pH must be maintained
between
7.0 and 8.0.
* Maintain
water hardness
below 7 grains
hardness.
* Filling
with
chlorinated
fresh
water
should
be acceptable
since drinking
water
chlorine
levels are typically
less than
5 ppm. Do not fill boiler with water
containing
chlorine
in
excess of 100 ppm.
