GAS-FIRED WATER BOILER – 80/110/150/199 BOILER MANUAL
When removing a boiler from an
existing common vent system
ECO
Tec
. When an existing boiler is replaced with an ECO
Tec
boiler, the ECO
Tec
boiler CANNOT use the existing common
vent. The boiler requires its own vent and air piping, as specified
in this manual. This may cause a problem for the appliances that
remain on the old common vent, because the vent may be too large.
The following test is intended to check for proper operation of the
appliances remaining on the old common vent system.
Perform the test sequence below for appliance remaining on the
original common vent system. Operate each appliance individually,
with other appliances turned off. This procedure will test whether
the common vent system can properly vent each appliance.
Existing vent test procedure
(The following is intended to test whether the appliances
remaining on an existing vent system will operate satisfactorily.)
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and
horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion or other deficiencies which could
cause an unsafe condition.
3. Test vent system — Insofar as is practical, close all building
doors and windows and all doors between the space in which
the appliances remaining connected to the common venting
system are located and other spaces of the building. Turn on
clothes dryers and any appliance not connected to the common
venting system. Turn on any exhaust fans, such as range hoods
and bathroom exhausts, so they will operate at maximum speed.
Do not operate a summer exhaust fan. Close fireplace dampers.
Any improper operation of a common venting system should be
corrected so the installation conforms with the National Fuel Gas
Code, ANSI Z223.1/NFPA 54 – latest edition, and/or the Natural
Gas and Propane Installation Code, CAN/CSA B149.1. When
resizing any portion of a common venting system, the common
venting system should be resized to approach the minimum size
as determined using the appropriate tables in Chapter 13 of the
National Fuel Gas Code, ANSI Z223.1/NFPA 54 – latest edition,
and/or the Natural Gas and Propane Installation Code, CAN/
CSA B149.1.
Do not install the ECO
Tec boiler into a common
vent with any other appliance. This will cause flue
gas spillage or appliance malfunction, resulting in
possible severe personal injury, death or substantial
property damage.
Existing common vent systems may be too large
for the appliances remaining connected after the
existing boiler is removed.
Failure to follow all instructions can result in
flue gas spillage and carbon monoxide emissions,
causing severe personal injury or death.

4. Place in operation the appliance being inspected. Follow the
lighting instructions. Adjust thermostat so appliance will
operate continuously.
5. Test for spillage at draft hood relief opening after 5 minutes of
main burner operation. Use the flame of a match or candle,
or smoke from a cigarette, cigar, or pipe.
6. After it has been determined that each appliance remaining
connected to the common venting system properly vents
when tested as outlined herein, return doors, windows,
exhaust fans, fireplace dampers, and any other gas-burning
appliance to their previous conditions of use.
