Ensure that the high gas pressure regulator is as least 6 – 10
feet upstream of the appliance. Failure to do so could result in
substantial property damage, severe personal injury, or death.

A. Check / Control Water Chemistry
Chemical imbalance of your water can cause severe damage to your
boiler and associated equipment, and may also affect efficiency.
You may have to have your water quality professionally analyzed
to determine whether you need to install a water softener. It is
important that the water chemistry on both the domestic hot water
and central heating sides are checked before installing the boiler, as
water quality will affect the reliability of the system. Outlined below
are those water quality parameters which need to be met in order
for the system to operate efficiently for many years. Failure of a heat
exchanger due to lime scale build-up on the heating surface, low pH
or other imbalance IS NOT covered by the warranty.
Thoroughly clean and flush any system that has used glycol before
installing the boiler. Provide the customer with a material safety data
sheet (MSDS) on the fluid used.
To assure extended service life, it is recommended to test water quality
prior to installation. Listed below are some guidelines.
Do not use petroleum-based cleaning or sealing compounds in the
boiler system. Damage to elastomer seals and gaskets in the system
could occur, resulting in substantial property damage.
Closed loop water must be free of corrosive chemicals, sand, dirt, and
other contaminates. It is up to the installer to ensure the water does
not contain corrosive chemicals or elements that can damage the heat
exchanger.
If you suspect that your water is contaminated in any way, discontinue
use of the appliance and contact an authorized technician or licensed
professional.
The boiler is equipped with a damper actuator. This actuator is
modulated by the system control to manage boiler combustion. It is
important that the damper actuator selector switch is set to “0”. See
Figure 29 for correct positioning.
Ensure the damper actuator selector switch is set to “0”. Turning
the damper actuator selector switch to “1” will result in improper
boiler operation. Service calls to repair this condition ARE NOT
covered by warranty.
