Operating instructions

IF REPLACEMENT PARTS ARE NEEDED
When parts are needed, refer to boiler model and serial number
shown on the boiler name/rating plate.Whenever possible refer
to the original order by number and date.
Control identification and replacement should not be attempted
by unskilled personnel. Only simple, easily-identified controls
and parts maybe obtained locally. All other controls and parts
should be identified by and ordered from Slant/Fin. Relief/Safe-
ty 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.
(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
system are located and other spaces of the building. Turn
on clothes dryer and any appliance not connected to the
common venting system. Turn on any exhaust fans, such
as range hoods and bathroom exhausts, so they will oper-
ate 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.
(e) Test for spillage at the draft hood relief opening after 5 min-
utes 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 Z2231 latest edition or CSA
B 149.1 latest edition for natural gas and propane. 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
Z2231 latest edition or CSA B 149.1 latest edition for
natural gas and propane.
APPENDIX A
Removal of Existing Boiler from Common Vent System
"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."
Thermostatic bypass valves type TV are designed to allow
boilers to reach their optimum operating temperature quickly
and to prevent cool/cold return temperatures from affecting
them.
Operation/Installation: The thermostat within the "TV" valve
allows full flow through the bypass until the predetermined
temperature is reached.
Start Up: With the balancing valve on the bypass fully open,
operate the boiler until it reaches its normal operating temper-
ature. If hot water does not automatically flow to the system
then adjust (throttle) the bypass balancing valve until flow (hot
water) to the system is established. If flow is already to the sys-
tem, no adjustment is required.
Return Mounting: On the return "TV" allows full bypass until the
return temperature reaches 46 degrees Celsius (115 degrees
Fahrenheit). "TV" will begin opening while main taining a 46
degrees Celsius (115 degrees Fahrenheit) minimum return
temperature. When return temperatures reach approximately
54 degrees Celsius (130 degrees Fahrenheit) most of the flow
will be through the system.
Mounting: "TV" can be installed in any position. An adjust able
balancing valve (or ball valve) must be installed on the bypass.

The flow factor Kv is the number of cubic meters per hour of water at 20°C which will flow through the valve with a pressure drop of 1kg/cm

(1 bar).
The flow coefficient Cv is the flow of water at 60°F in US gallons per minute at a pressure drop of 1lb/in

across the valve.
