exhaust fan. Close fireplace dampers.
Place in operation the appliance being inspected. Follow the

lighting instructions. Adjust thermostat so appliances will
operate continuously.
5. 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.

The boiler must be located on a surface that can support
the weight of the installed 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
IMPORTANT: For piping examples using the Gas-Fired
Direct Vent Modulating Hot Water Boiler, see the Piping
Appendix in Section XVI of this manual. and operation.
Copper supply and return piping must NOT be installed
directly into aluminum boiler section castings due to
galvanic corrosion between dissimilar metals. Iron or steel
!
bushings or pipe nipples should be used between cop-
per system piping and boiler to make final connection to
boiler. Also, the use of dielectric unions is acceptable. The
packaged boiler is furnished with iron piping where neces-
sary for the supply and return connections.
When the installation of the boiler is for a new heating system, first
install all of the radiation units (panels, radiators, baseboard, or tub-
ing) and the supply and return mains. After all heating system piping
and components have been installed, make final connection of the
system piping to the boiler.
According to code, a hot water boiler installed above radiation level
must be equipped with a low water cut off device. A periodic inspec-
tion is necessary, as is flushing of float type devices, per low water
cut off manufacturers specific instructions. This boiler is factory
equipped with a manual reset probe-type low water cut
off.

6. Any improper operation of the common venting system should
be corrected so the installation conforms with the National Fuel
Code, NFPA-54/ANSI -Z223.1-latest revision, or section 5 of
CSA-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 the National Fuel Gas Code,
NFPA-54/ANSI- Z223.1-latest revision, or section 5 of CSA-
B149 for Canadian standards.
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 floor or
surface.
NOTE: Refer to "Locating The Boiler" in Section V of this
manual for required clearances for servicing and mainte-
nance.
expansion tank & make-up water
!
Non-potable water only piped directly to boiler. DO NOT
connect drinking water to heating system.
Determine required system fill pressure, system design
temperature, and system water content. Boiler contains
2.6 gallons (US). Size expansion tank accordingly. Consult
expansion tank manufacturer for proper sizing information.
Connect properly sized expansion tank (not furnished) as
shown in Figure 6 for diaphragm type expansion tank. For
diaphragm type expansion tanks, adjust the tank air pressure
to match the system fill pressure. Install air vent (furnished) as
shown for diaphragm type expansion tank system only. Install
make-up water connections as shown and per local codes. If a
pressure reducing valve is used, adjust to match the system fill
pressure. In connecting the cold make-up water supply to the
boiler, make sure that clean water supply is available. When the
water supply is from a well or pump, a sand strainer should be
installed at the pump.
