NOTE: DAMAGE TO THE BOILER CAUSED BY EXPOSURE TO
CORROSIVE VAPORS IS NOT COVERED BY WARRANTY.
(Refer to
the limited warranty for complete terms and conditions.)
I. Removing a Boiler from a Common Vent System
Failure to follow all instructions can result in flue gas spillage and
carbon monoxide emissions, causing severe personal injury or
death.
Do not install the boiler into a common vent with any other
appliance. This will cause flue gas spillage or appliance
malfunction, resulting in possible substantial property damage,
severe personal injury, or death.
When removing an existing boiler, follow the steps below.
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and horizontal
pitch to determine if there is blockage, leakage, corrosion, or other
deficiencies that could cause an unsafe condition.
3. If practical, close all building doors, windows, and doors between
the space in which the boiler remains connected to the common
venting system and other spaces in the building. Turn on clothes
dryers and any appliances not connected to the common venting
system. Turn on any exhaust fans, such as range hoods and bathroom
exhausts, at maximum speed. Do not operate a summer exhaust fan.
Close all fireplace dampers.
4. Place in operation the appliance being inspected. Follow the
lighting instructions. Adjust the thermostat so the appliance will
operate continuously.
5. Test for spillage at the draft hood relief opening after 5 minutes of
main burner operation. Use the flame of a match or candle or smoke
from a cigarette.
6. After it has been determined that each appliance remaining
connected to the common venting system properly vents when
tested as outlined, return doors, windows, exhaust fans, fireplace
dampers, and any other gas burning appliances to their previous
condition of use.
7. Any improper operation of the common venting system should
be corrected to conform to the National Fuel Gas Code, ANSI Z223.1.
When resizing any portion of the common venting system, the
system should approach the minimum size as determined using the
appropriate tables in Appendix G of ANSI Z223.1.

J. Water Chemistry Requirements*
Chemical imbalance of the water supply may affect efficiency and
cause severe damage to the appliance and associated equipment. It
is important that the water chemistry on both the domestic hot water
and central heating sides are checked before installing the appliance.
Water quality must be professionally analyzed to determine whether
it is necessary to treat the water. Various solutions are available to
adjust water quality. Adverse water quality will affect the reliability
of the system. In addition, operating temperatures above 135
o
F will
accelerate the build-up of lime scale and possibly shorten appliance
service life. Failure of an appliance due to lime scale build-up, low pH,
or other chemical imbalance IS NOT covered by the warranty.
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.
• Water pH between 6.5 and 8.5
• pH levels below 6.5 can cause an increase in the rate of
corrosion. pH of 8.5 or higher can potentially cause lime scale
build-up
• Maintain water pH between 6.5 and 8.5. Check with litmus
paper or have it chemically analyzed by a local water
treatment company.
• If the pH is not between 6.5 and 8.5, consult a local water
treatment company for solutions.
• Hardness less than 7 grains (120 mg/L) (Water temperatures
of 140
o
F and greater)
• Hardness levels above the required amounts can lead to lime
