PIPING A HEATING - COOLING SYSTEM TO A WATER
BOILER AND CHILLER
The chiller must be piped in parallel with the boiler. Figure
below illustrates a method of piping a heating-cooling system
to a water boiler and a chiller. Hand valves (shown) or auto-
matic valves must be installed to prevent circulation of chilled
water in the boiler or hot water in the chiller.
The air control system and pressure control system must
operate with chiller only, or the boiler only, being valved to the
IF REPLACEMENT PARTS ARE NEEDED
When parts are needed, refer to boiler model and serial num-
ber shown on the boiler name/rating plate. Refer to publica-
tion number SE-11PL Sentinel Replacement Parts for part
numbers. Whenever possible refer to the original order by
number and date.
Control identification and replacement should not be attempt-
ed by unskilled personnel. Only simple, easily-identified con-
trols and parts may be obtained locally. All other controls and
"At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining connected to
the common venting system placed in operation, while the other appliances remaining connected to the common venting system
are not in operation."
(a) Seal any unused openings in the common venting system.
(b) Visually inspect the venting system for proper size and
horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion and other deficiencies which
could cause an unsafe condition.
(c) Insofar as is practical, close all building doors and win-
dows and all doors between the space in which the appli-
ances remaining connected to the common venting sys-
tem are located and other spaces of the building. Turn on
clothes dryer and any appliance not connected to the com-
mon venting system. Turn on any exhaust fans, such as
range hoods and bathroom exhausts, so they will operate
at maximum speed. DO NOT operate a summer exhaust
fan. Close fireplace dampers.
(d) Place in operation the appliance being inspected. Follow
the lighting instructions. Adjust thermostat so appliance
will operate continuously.
APPENDIX A
Removal of Existing Boiler from Common Vent System
piping system.
Separate control devices on the boiler and chiller may be
used, or a single set of air and pressure controls on the com-
mon piping may be preferred.
If the boiler is used to supply hot water to heating coils in air
handling units, flow control valves or other devices must be
installed to prevent gravity circulation of water in the coils dur-
ing the cooling cycle.
parts should be identified by and ordered from Slant/Fin.
Relief/Safety valves must be ASME rated for the pressure and
gross output of the boiler.
For replacement parts, heating contractors should contact
their Slant/Fin boiler distributor.
(e) Test for spillage at the draft hood relief opening after 5
minutes of main burner operation. Use the flame of a
match or candle, or smoke from a cigarette, cigar or pipe.
(f) After it has been determined that each appliance remain-
ing connected to the common venting system properly
vents when tested as outlined above, return doors, win-
dows, exhaust fans, fireplace dampers and any other gas-
burning appliance to their previous conditions of use.
(g) Any improper operation of the common venting system
should be corrected so the installation conforms with the
National Fuel Gas Code, ANSI Z223.1-latest edition.
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 Appendix G in the National Fuel Gas
Code, ANSI Z223.1-latest edition.
