Foundation Requirements
Boiler must be placed on level surface. Boiler is NOT to be
installed on carpeting.
NOTICE
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.
Wood frame or blocks may be used to raise
boiler to maintain drain pitch or to be above
external condensate pump reservoir.
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.
Seal any unused openings in the common venting
1.
system.
Visually inspect the venting system for proper size and
2.
horizontal pitch and determine there is no blockage
or restriction, leakage, corrosion or other defi ciencies
which could cause an unsafe condition.
In so far as is practical, close all building doors and
3.
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 fi re dampers.
Place in operation the appliance being inspected.
4.
Follow the lighting instructions. Adjust thermostat so
appliances will operate continuously.
Test for spillage at the draft hood relief opening after 5
5.
minutes of main burner operation. Use the fl ame of a
match or candle, or the smoke from a cigarette, cigar
or pipe.
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.
Any improper operation of the common venting system
7.
should be corrected so the installation conforms with
the National Fuel Code, ANSI Z223.1/NFPA 54, or
Natural Gas and Propane Installation Code, CAN/CSA
B149.1. 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 chapter 13 of the
National Fuel Code, ANSI Z223.1/NFPA 54, or Natural
Gas and Propane Installation Code, CAN/CSA B149.1.
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 right
hand side of the boiler. It is possible to slide the boiler for
a short distance on a smooth fl oor or surface.
