Flooring and foundation

Do not install boiler on combustible
flooring or carpeting even if a concrete or
aerated foundation is used. Fire can result,
causing severe personal injury, death or
substantial property damage.
1. See Figure 2. A level concrete or solid brick pad is
required if:
a) There is a possibility of the floor becoming flooded.
b) Non-level conditions exist.
2. An aerated boiler foundation is recommended if
any of the following conditions exist:
a) Electrical wiring or telephone cables buried in the
concrete floor of the boiler room.
b) Concrete floor is "green."
c) There is a history of the floor becoming flooded.
d) Water is channeled under the concrete.

Vent System

Failure to follow all instructions can result in flue gas spill-
age and carbon monoxide emissions, causing severe personal
injury or death.
Inspect existing chimney before installing boiler. Failure to
clean or replace perforated pipe or tile lining will cause severe
personal injury or death.
Do not alter boiler draft diverter or place any obstruction or
non-certified vent damper in breeching or vent system. CSA
certification will become void. Flue gas spillage and carbon
monoxide emissions will occur causing severe personal injury
or death.
The following requirements apply when you remove an exist-
ing boiler from a vent system shared with other appliances. If
the new boiler will not use the common vent, you must test
(as described below) each remaining appliance — operating
by itself — to verify that the vent system operates adequately.
When removing boiler from existing common vent system:
At the time of removal of an existing boiler, the following steps shall be
followed with each appliance remaining connected to the common venting
system placed in operation, while the other appliances remaining connected
to the common venting system are not in operation.
a. Seal any unused openings in the common venting system.
b. 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.
c. Test vent system — Insofar as is practical, close all building doors and
windows and all doors between the space in which the appliances re-
maining 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.
d. Place in operation the appliance being inspected. Follow the lighting
instructions. Adjust thermostat so appliance will operate continuously.
e. Test for spillage at draft diverter relief opening after 5 minutes of main
burner operation. Use the flame of a match or candle.
f. After it has been determined that each appliance remaining connected
to the common venting system properly vents when tested as outlined
above, return doors, windows, exhaust fans, fireplace dampers, and any
other gas-burning appliance to their previous conditions of use.
Any improper operation of the common venting system should be corrected
so the installation conforms with the National Fuel Gas Code, ANSI Z223.1/
NFPA 54 and/or CAN/CGA B149 or B149.2, Installation Codes. When resiz-
ing any portion of the common venting system, the common venting system
should be resized to approach the minimum size as determined using the
appropriate tables in the National Fuel Gas Code, ANSI Z223.1/NFPA 54
and/or CAN/CGA B149 or B149.2, Installation Codes.
