WARNING
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
installed in locations where propane leaking from defective
quipment and piping will “pool” in a basement or other space
e
below the leak.
A spark or flame from the boiler or other source may ignite
the accumulated propane gas causing an explosion or fire.
rovide a level, solid foundation for the boiler. Location should
P
be as near the chimney as possible so that the flue pipe from
boiler to chimney is short and direct.
The 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 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 National Fuel Gas Code.
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” 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.
Sentry
INIMUM CLEARANCES FROM COMBUSTIBLE
M
CONSTRUCTIONS
A. Minimum boiler clearances shall be as follows:
SENTRY SERIES
MINIMUM CLEARANCE FOR COMBUSTIBLE CONSTRUCTION. MINIMUM ALCOVE AND CLOSET CLEARANCE.
S-34 through
S-150
Front 6"
Rear 6"
Left Side 6"
Right Side 12"
Top (above boiler) 12"
Flue Connector 6"
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
learance at the opening through the finished floor, wall or ceiling boards
c
ay not be less than 1/2 inch. Each such opening shall be covered with
m
a plate of non-combustible material.
SAFETY—
KEEP THE BOILER AREA CLEAR AND FREE FROM
COMBUSTIBLE MATERIALS, GASOLINE AND OTHER
FLAMMABLE VAPORS AND LIQUIDS.
VENT PIPING—
A. Vent piping installation must be in accordance with ANSI
Z223.1-latest edition, National Fuel Gas Code, 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
must be supported to prevent sagging by securing each joint
with metal screws and by providing hanger spaced no
greater than 5 feet apart.
Sentry
D. Vent or breeching into chimney should not be inserted past
the inside wall of the chimney liner.
. All venting means should be inspected frequently. See Care
E
and Maintenance and separate User's Information Manual.
VENT DAMPER INSTALLATION
he vent damper referred to in the following instructions is
T
the Slant/Fin Corporation vent damper.
This device is design certified by A.G.A. for use ONLY on spe-
ific Slant/Fin Corp. gas boiler models. These boilers must also
c
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.
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 and 2).
4. Carefully unpack the unit. DO NOT FORCE IT OPEN OR
CLOSED. Forcing the damper may damage the gear
train and void the warranty.
B. 1. This device must be installed after the boiler draft hood
(between the draft hood outlet and the connector to the outdoor chimney or vent) as close to the draft hood as practicable, and without modification of the draft hood or the vent
damper. (See figures 1, 2 and 3.)
2. The inlet size of the vent damper must be the same nominal trade size as the outlet of the draft hood.
3. This device must be located in a venting system or section
of a venting system so that it serves only the single appliance for which it is installed. (See figure 3.)
4. Clearances of not less than 6 inches (152MM) must be
maintained from combustible materials, with provisions for
service access.
C. AFTER INSTALLATION:
1. Operate system through two complete cycles to check for
opening and closing in proper sequence, and proper burner operation. DAMPER MUST BE IN OPEN POSITION
WHEN BOILER MAIN BURNERS ARE OPERATING.
2. Perform installation checks as required by ANSI specification Z21.66. (See Vent Damper Instructions.)
3. Check the troubleshooting section if problems arise with the
installation.

WARNING—DANGER
Once you have begun vent damper installation procedure, DO
NOT restore electric power and gas supply until installation and
inspection have been completed (in order to prevent the main
burners from operating). DO NOT operate the boiler until the vent
damper harness is plugged into vent damper operator. Failure to
observe this warning may create a hazardous condition that
could cause an explosion or carbon monoxide poisoning.

GAS PIPING—
A. Local installation codes apply. The pipe joint compound used
on threads must be resistant to the action of liquefied petroleum gases.
B. The gas supply line to the boiler should be run directly from
the meter for natural gas or from the fuel tank for L.P.
propane gas. See page 2 for location of union and manual
main shutoff valve that may be specified locally.
Selecting pipe size for natural gas:
1. Measure or estimate the length of piping from the meter
to the installation site.
2. Consult gas supplier for heating value of gas (Btu/cu. ft.).
3. Divide boiler rated input by heating value to find gas flow
in piping (cu. ft. per hour).
4. Use table A to select proper pipe size.
Example
: Boiler model S-150 is to be installed. Distance
from gas meter to the boiler is 30 ft. Heating value of natural gas is 1020 Btu/cu. ft. Select proper pipe size.
Gas flow = 150,000 Btu/hour
= 147 cu. ft. per hour
1020 Btu/cu.ft.
At 30 ft. length of pipe, match required capacity from Table A
(choose higher capacity, in this case is 152 cu. ft. per hour).
Required pipe size is 3/4".
Improper gas pipe sizing will result in pilot flame outages,
insufficient heat and other installation difficulties. For more
information and also if other appliances are to be attached
to the piping system, see Appendix C of National Fuel Gas
Code ANSI Z223.1-latest edition.
C. The boiler and its gas connection must be leak tested before
placing the boiler in operation. Use liquid soap solution for all
gas leak testing. DO NOT use open flame.
This boiler and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 PSIG.
This boiler must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 PSIG.
D. All gas piping used should be inspected thoroughly for
cleanliness before makeup. A sediment trap must be provided, as illustrated on page 2.
E. The minimum and maximum gas supply pressure (at the
inlet of gas valve) are shown on the boiler rating plate for the
type of gas used. Gas supply pressure should never be less
than minimum or more than maximum pressure when the
boiler or any other appliance is turned on or off.
ELECTRICAL CONTROLS AND WIRING—
A. The electrical power to the boiler must be on a separately
fused and live circuit.
B. The boiler, when installed, must be electrically grounded in
accordance with the requirements of the authority having
jurisdiction or, in absence of such requirements, with the
National Electrical Code, ANSI/NFPA No. 70-latest edition.
C. See figure 5a and 5b for wiring diagram on pages 8 and 9.

boiler control (See figure 4). Connect ground wire to ground
screw inside boiler control.
3. Thermostat Connections
Thermostat wire connections must be to T and TV screw
terminals of boiler temperature control (See figure 4).
Thermostat Heat Anticipator Adjustments
If the 24V room thermostat that controls this boiler has an
adjustable heat anticipator, connect entire system to thermostat
and run the system while measuring the current drawn through
the thermostat wires. Set the heat anticipator at the value
measured. The set current should match power requirements by
zone valves and relays. Add an additional 0.1 Amp to the
measured current for vent dampers. Refer to the manufacturer’s
instructions of zone valve, vent damper and relays. Also, see
instructions with the thermostat.
4. Multi Zoning
For pump zoning system, see figure 5 and 6 for zone valve
system, see figure 7. DO NOT use control transformer to
power external accessories like zone valve and relay, over
load and/or burned-out transformer and boiler malfunction
can result.
5. Indirect External Water Heater
If the system includes indirect water heater, the indirect signal
must be sepatayed from heating zone(s) system. See figure 6
and follow steps below:
a. Connect end switch of the indirect water heater relay to I1
and I2 of the boiler temperature control.
b. Connect end switch of the heating zones(s) relays to T and
TV of the boiler temperature control.
c. Power DHW and heating zone(s) circulators through end
switch relays as shown on figure 6. Do not connect heating
zone(s) circulators to C1 and C2 of the control.
