NATURAL GAS-FIRED BOILER LOCATION
Pilot
Burner
Access
Door
Gas Valve
Provide a level, solid foundation for the boiler. Location should be
as near as possible to chimney or outside wall so that the flue pipe
from boiler is short and direct.
The location should also be such that the gas ignition system components are protected from water (dripping, spraying, rain, etc.)
during appliance operation and service (circulator replacement,
condensate trap, control replacement, etc.).
BOILER FOUNDATION
A. Provide a solid, level foundation, capable of supporting the
weight of the boiler filled with water, and extending at least 2"
past the jacket on all sides. See dimensions of boiler, page 2.
B. For installation on non-combustible floors only. The
Combustible Floor Kit part number printed on the boiler rating
plate is the only one to be used when installing on combustible
floors. The boiler must not be installed on carpeting.
C. If boiler is to be located over buried conduit containing electric
wires or telephone cables, consult local codes or the National
Board of Fire Underwriters for specific requirements.

ARNING
LIQUEFIED PETROLEUM (L.P.) PROPANE
GAS-FIRED BOILER LOCATION
REQUIRES SPECIAL ATTENTION
Liquefied Petroleum (L.P.) propane gas is
heavier than air.
Therefore, propane boilers, piping, valves should not be
i
nstalled in locations where propane leaking from defective
equipment and piping will “pool” in a basement or other space
below the leak.
A
spark or flame from the boiler or other source may ignite
the accumulated propane gas causing an explosion or fire.
Provide a level, solid foundation for the boiler.Location should
be as near the chimney as possible so that the flue pipe from
boiler to chimney is short and direct.
T
he UNIFORM MECHANICAL CODE may be in effect in
your geographic area
The following precautions are cited by the 1994 UNIFORM
MECHANICAL CODE, section 304.6:
“LPG Appliances. Liquefied petroleum gas-burning
appliances shall not be installed in a pit, basement or similar location where heavier-than-air-gas might collect.
Appliances so fueled shall not be installed in an abovegrade under-floor space or basement unless such location is provided with an approved means for removal of
unburned gas.”
Consult Chapter 5 of the 1994 UNIFORM MECHANICAL
CODE for design criteria of the “approved” means for removal
of unburned gas.
CHIMNEY REQUIREMENTS
A. Sentry boilers may be vented into a masonry vitreous tile-
lined chimney or type “B” venting system NOT EXPOSED to
the OUTDOORS below the roof line.
Venting and sizing of venting system must be in accordance
with Part 7, Part 10 and Appendix G of the National Fuel
Gas Code ANSI Z223.1, NFPA 54, -latest edition which will
be referred to as the National Fuel Gas Code. Local codes
apply.
If a masonry chimney is exposed to the outdoors on one or
more sides below the roof line (exterior chimney), ONE of
the following options apply:
1. Chimney must be re-lined with a metallic liner. When this
is done, the chimney will be considered NOT exposed to
the outdoors and the requirements of the National Fuel
Gas Code for NON-exposed chimneys and/or local codes
will apply.
2. If an exposed tile-lined chimney is to be used WITHOUT
a metallic liner, the boiler must first meet the requirements of the following tables and paragraphs of the
National Fuel Gas Code:
I. For Single Sentry Boiler - Paragraph 10.1.9 and
table 10.11.
II. For multiple appliances - Paragraph 10.2.18 and table
10.12 (or 10.13 if applicable).
In addition, all requirements of Part 7, Part 10 and
Appendix G of the National Fuel Gas Code and/or local
codes apply.
B. If an existing boiler is removed from a common venting
system, the common venting system may be too large
for proper venting of the remaining appliances connected to
the common vent. Follow the test procedure shown in
Appendix “A” on page 19 of this manual to insure proper
operation of venting system and appliances.
C. Inspect for proper and tight construction. Any restrictions or
obstructions must be removed. An existing chimney may
require cleaning.
D. Chimney or vent must extend at least 3 feet above any
ridge within 10 feet of the chimney.

A. Minimum boiler clearances shall be as follows:
B. Provide accessibility clearance of 24” on sides requiring
servicing and 18” on sides used for passage.
C. All minimum clearances shown above must be met. This
may result in increased values of some minimum clearances
in order to maintain the minimum clearances of others.
D. Clearance from hot water pipes shall be 1 inch**.
** At points where hot water pipes emerge from a floor wall or ceiling, the
clearance at the opening through the finished floor, wall or ceiling boards
may not be less than 1/2 inch. Each such opening shall be covered with
a plate of non-comb

le mater
ial.
SAFETY—
KEEP THE BOILER AREA CLEAR AND FREE FROM
COMBUSTIBLE MATERIALS, GASOLINE AND OTHER
FLAMMABLE VAPORS AND LIQUIDS.
DRAFT HOOD—
The draft hood supplied with SX-150 through SX-210 models is
part of the listed boiler assembly. DO NOT alter the hood. See
dimensions, page 2.
Attach the hood to the boiler flue outlet. Connect flue pipe full
size of hood outlet. Vent damper must be installed on the outlet
side of the hood. See Vent Piping, below.
VENT PIPING—
A. Vent piping installation must be in accordance with ANSI
Z223.1-latest edition, National Fuel Gas Code, Part 7,
Venting of Equipment. Other local codes may also apply and
must be followed.
B. Boiler vent pipe must be the full diameter of the boiler outlet.
See dimensions, page 2.
C. If more than one appliance vents into a common breeching,
the area of the breeching must be equal to the area of the
largest vent plus 50% of the area of the additional vent
areas. Vent connectors serving appliances vented by natural draft shall not be connected into any portion of mechanical draft systems operating under positive pressure.
Horizontal breeching or vent pipe should be as high as possible, consistent with codes, so that vertical vents from appliances will have a high rise above draft diverter openings. All
horizontal runs must slope upwards not less than 1/4 inch
per foot of run. Horizontal portions of the venting system
Sentry

must be supported to prevent sagging by securing each joint
with metal screws and by providing hanger spaced no
greater than 5 feet apart.
D. Vent or breeching into chimney should not be inserted past
the inside wall of the chimney liner.
E. All venting means should be inspected frequently. See Care
and Maintenance and separate User's Information Manual.
V
ENT DAMPER INSTALLATION
The vent damper referred to in the following instructions is
the Slant/Fin Corporation vent damper.
This device is design certified by A.G.A. for use ONLY on specific Slant/Fin Corp. gas boiler models. These boilers must also
be equipped with a plate which states that the boiler may be
used with a Slant/Fin Corp. automatic vent damper device and
indicates the proper vent damper model number. This device
cannot be used with millivolt ignition system.
A. INSTALLATION INSTRUCTIONS BEFORE YOU START TO
INSTALL
1. Read this installation manual, the "DANGER" plate
attached to the top of the boiler, the "WARNING" on the
wiring diagrams, vent damper carton and operator cover.
2. Perform pre-installation inspection as required by ANSI
specification Z21.66. (See Vent Damper Instructions.)
3. Select a proper, convenient location for vent damper.Vent
damper may be installed vertical or horizontal on all models (see figures 1, 2 and 3).
