GV100W BOILER
INSTALLATION & OPERATING INSTRUCTIONS
The owner should maintain a record of all service work
performed with the date and a description of the work done.
Include the name of the service organization for future reference.
Where required by the authority having jurisdiction, the
installation must conform to the Standard for Controls and Safety
Devices for Automatically Fired Boilers, ANSI/ASME CSD-1.
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. In Canada, the installation must be in
accordance with the requirements of CAN/CGA B149
Installation Code for Gas Burning Appliances and Equipment.
BOILER RATINGS & CAPACITIES
Before undertaking the installation of the GV100W check the
boiler rating plate to ensure that the boiler is the proper size
for the job. The “Net I=B=R Ratings” specify the equivalent
amount of direct cast iron radiation that the boiler can handle
under normal conditions.
Also ensure that the boiler has been set up for the type of gas
available at the installation site. Other important considerations
are the availability of an adequate electrical supply, fresh air
for combustion and a suitable chimney or vent system location.
BOILER LOCATION
WARNING: This boiler is for installation on non-
combustible floors only! A special base supplied by
the manufacturer must be used to install this boiler
on a combustible floor. Failure to comply with this
wwwwarning could result in property damage,
severe personal injury or death!
1. Locate the boiler in an area that provides good access to
the unit. Keep in mind that servicing may require the removal
of jacket panels. Accessibility clearances must take precedence
over fire protection clearances.
2. An optimum site will be level, central to the hot water piping
system, close to a chimney or outside wall and have adequate
fresh air for combustion.
3. Ensure that the floor is structurally sound and will support
the weight of the boiler. This boiler is designed for non-
combustible floors only! A special base supplied by Smith Cast
Iron Boilers must be used if the boiler is to be installed on a
combustible floor. Never install this boiler on carpeting!
4. Do not install this boiler in a location that would subject
any of the gas ignition components to direct contact with water
or excessive moisture during operation or servicing.
CAUTION: Do not install this boiler in a location subject
to negative pressures or improper operation will occur.
5. Do not place this boiler in a location that would restrict
the introduction of combustion air into the boiler. NEVER store
objects on or around the boiler.
WARNING: Never store combustible materials,
gasoline or any product containing flammable vapors
or liquids in the vicinity of the boiler. Failure to
comply with this warning can result in extensive
property damage, severe personal injury or death!
6. If the boiler is to be located in an alcove, closet or other
confined space the distances from the boiler and it’s vent
system to all combustible construction must be equal to or
greater than the minimum clearances in Figure 1. When
installed in a closet or confined space two permanent openings
of equal area adjoining another room or rooms having sufficient
volume to meet the requirements of an unconfined space must
be provided. Each opening must have a minimum free area of
one square inch per 1000 Btu/hr,
2200 mm
2
/kW
based on the
total input rating of all gas utilization equipment in the confined
area. Each opening must be no less than 100 in

,
64516 mm

,
in size. The upper opening must be within 12 in, 305
mm
, of,
but not less than 3 in,
76 mm
, from the top of the enclosure.
The bottom opening must be within 12 in,
305 mm
, of, but not
less than 3 in,
76 mm
, from the bottom of the enclosure.
WARNING: Never install a PGV100W, propane boiler
in a closet or other confined or enclosed space!
Failure to comply with this warning could result in a
fire or explosion causing extensive property damage,
severe personal injury or death!
