REQUIREMENTS
Boiler must be placed on level surface.
Boiler is NOT to be installed on carpeting.
NOTE:
1. If boiler is not level condensate
drain lines will not function properly.
Adjustable
feet
are located on the boiler to make up for minor surface irregularities
or tilt.
2. Wood frame or blocks may be used to raise boiler to maintain drain pitch or to be
above external
condensate
pump reservoir.
H. REMOVAL
OF EXISTING
BOILER
FROM COMMON
VENT SYSTEM
When an existing boiler is removed
from a common venting system, the common venting system
is likely to be too large for proper venting of the appliances
remaining
connected to it. 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.
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 restrictions,
leakage,
corrosion
and other deficiencies
which could cause an
unsafe condition.
3.
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 dryer and any appliance
not connected
to the
common venting system. Turn on any exhaust fans, such as range hoods and bathroom
exhaust,
so they will operate
at maximum
speed. Do not operate a summer exhaust fan. Close
fire dampers.
4.
Place in operation
the appliance
being inspected.
Follow the lighting instructions.
Adjust
thermostat
so appliances
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 the 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 above, return doors, windows,
exhaust fans and
any other gas-burning
appliance
to their previous
condition
of use.
7.
Any improper
operation
of the common venting system should be corrected
so the installation
conforms
with the National
Fuel Code, NFPA-54/ANSI
-Z223. l-latest
revision,
or section 5
of CAN/CGA-B149
for Canadian
standards.
When resizing 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 part I 1 in the National
Fuel Gas Code, NFPA-
54/ANSI-
Z223. l-latest
revision,
or section 5 of CAN/CGA-B149
for Canadian
standards.
PLACING THE BOILER
The boiler should be placed to provide the most direct connections
to the combustion
air, vent and
system piping as possible.
Place crated boiler as close to selected
location as possible and uncrate
boiler. The uncrated
boiler
may be moved into position with an appliance
dolly or 2-wheel hand truck. The dolly or hand truck
should be inserted under the left hand
side of the boiler.
It is possible to slide the boiler for a short
distance
on a smooth
floor or surface.
