2. Rules for Safe
Installation
&
Operation
1. Read this manual and the
Owner's Manual carefully.
Failure to follow the rules for
safe operation and the instruc-
tions could cause a malfunction
of the boiler and result in death,
serious injury, and/or property
damage.
2. Check your local codes and
utility requirements before
installation. The installation
must be in accordance with
their directives.
3. Before servicing, allow boiler to
cool and always shut off any
electricity and gas to boiler
when working on it. This will
prevent any electrical shocks or
burns.
4. Never test for leaks with open
flame. Use soap suds to check
all connections. This will avoid
any possibility of fire or explo-
sion.
5. Be certain boiler is equipped for
type of gas (natural or propane)
to be used. Over-firing will result
in premature failure of the boiler
sections and cause dangerous
operation.
6. Never vent this boiler into an
enclosed space. Always con-
nect the boiler to the outside.
Never vent to another room or
inside a building.
7. Be sure there is adequate air
supply for complete combus-
tion.
8. Follow a regular service and
maintenance schedule for effi-
cient and safe operation.
WHEN YOUR BOILER ARRIVES
BE SURE TO SAVE AND REFER
TO INSTRUCTION .S_"-
First, inspect each item received for
visible damage or shortage. If any
parts are damaged, report this to
the freight company immediately,
and request them to cell and make
an inspection before you make any
installation. Have the Inspector
prepare a signed report. Send
Vaillant a copy of this report and we
will send replacements for the
damaged parts. But, we must have
the signed inspection report of the
freight company to prove their
liability.
Examine all packaging material
carefully for loose parts before
discarding.
Also, store all parts received where
they will not be lost or damaged.
If you have had to unpack the boiler
outside, you may also have to dis-
assemble it to carry it to the installa-
tion area. In this case, use the Parts
List drawings herein to guide you.
NOTE: The GA1 O0 CS Series of
boilers were evaluated by the
American Gas Association to certify
that they meet all of the safety crite-
ria of ANSI standard 7_21.13a-Latest
Edition "Gas Fired Low Pressure
Steam and Hot Water Boilers." Safe
lighting and other performance crite-
ria were met with the gas manifold
and control assembly provided on
the boiler when the boiler underwent
tests specified in this standard.
The following steps are all neces-
sary for proper installation and safe
operation of the boiler.
1. Locating the boiler.
2. Fresh air for combustion.
3. Chimney & vent pipe connection.
4. System piping.
5. Gas supply piping.
6. Electrical wiring.
7. Check out and adjust.
8. Maintenance.
3, Locating the Unit
If unit is to be part of an existing
system, it is usually best to put it
where the old one was. If you plan
to change location, you will need
additional material as well as an
adequate base. The following rules
apply not only to replacement boil-
ers, they also apply to new installa-
tions:
1. The unit must be level.
2. Use a raised base if floor can
become wet or damp.
3. The vent pipe connection should
be short. The center of the chim-
ney opening must be high
enough to allow a '/," per ft.
upward slope in vent from unit
to chimney opening
4. Maintain clearances for fire safety
as well as servicing.
The room must have a total cubic
foot volume not less than 16
times that of the boiler.
5. Fresh air for combustion must be
available at the front of the boiler.
6. While this boiler may be installed
on combustible flooring, it must
not be installed on carpeting.
7. The installation must conform to
the requirements of the authority
having jurisdiction or, in the
absence of such requirements, to
the national Fuel Gas Code.
ANSI Z223.1-Latest Edition.
8. Where required by the authority
having jurisdiction, the installation
must conform to American
Society of Mechanical Engineers
Safety Code for Controls and
Safety Devices for Automatically
Fired Boilers, No. CSD-I.
Clearance from Combustible
Materials
The following minimum clearances
are required between boiler and
combustible construction:
Top ............................... 12 inches
Right Side ....................... 6 inches
Left Side ......................... 6 inches
Rear ................................ 6 inches
Flue Connector ............... 6 inches
Hot Water Pipe ................... 1 inch
Flue and stack must be at least 6"
from combustible surfaces.
If hot water pipe passes through
combustible floors, walls, or ceil-
ings, clearance must be not less
than ½" capped with a non-com-
bustible plate (see NFPA bulletin
89M, heating equipment clearance).
Servicing requirements may require
larger clearances than those
required for fire safety.
As the electrical and piping connec-
tions are at the rear of the unit,
there should be space to permit
access to the rear of the unit for ser-
vice.
