Removing Existing Boiler From Common Venting
System
When an existing boiler is removed from common venting
system, common venting system is likely to be too large for
proper venting of appliances remaining connected to it.
At time of removal of existing boiler, following steps shall
be followed with each appliance remaining connected to the
common venting system placed in operation, while other
appliances remaining connected to common venting system
are not in operation.
1.
Seal any unused openings in the common venting
system.
2.
Visually inspect the venting system for proper size and
horizontal pitch and determine there is no blockage or
which could cause an unsafe condition.
3.
Insofar as is practical, close all building doors and
windows and all doors between the space in which the
appliances remaining connected to the common venting
system are located and other spaces of the building.
Turn on clothes dryers 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 operate at maximum speed. Do not operate a
4.
Place in operation the appliance being inspected. Follow
the lighting instructions. Adjust thermostat so appliance
will operate continuously.
5.
Test for spillage at the draft hood relief opening after
a match or candle, or smoke from a cigarette, cigar or
pipe.
6.
After it has been determined that each appliance
remaining connected to the common venting system
properly vents when tested as outlined above, return
any other gas-burning appliance to their previous
conditions of use.
7.
Any improper operation of the common venting system
should be corrected so the installation conforms with
the National Fuel gas Code, ANSI Z223.1/NFPA 54,
and/or the Natural Gas and Propane Installation Code,
CAN/CSA B149.1. When re-sizing any portion of the
common venting system, the common venting system
should be re-sized to approach the minimum size
determined using the appropriate tables in Chapter 13
of the National Fuel Gas Code, ANSI Z223.1/NFPA 54,
and/or the Natural Gas and Propane Installation Code,
CAN/CSA B149.1.
WARNING
Do not connect boiler to any portion of mechanical
draft system operating under positive pressure.

!!
CHECK GAS SUPPLY
Gas pipe to your boiler must be correct size for length of
run and for total BTU per hour input of all gas utilization
equipment connected to it. See Table 5 for proper size.
Be sure your gas line complies with local codes and gas
company requirements.
CONNECTING THE GAS PIPING See Figure 11.
Gas line enters boiler from right side.
• Use piping materials and joining methods acceptable
to authority having jurisdiction. In absence of such
requirements:
• USA - National Fuel gas Code, ANSI Z223.1/NFPA 54
• Canada - Natural Gas and Propane Installation Code,
CAN/CSA B149.1
• Use pipe joint compound suitable for LP gas on male
threads only.
• Use ground joint unions.
• Install sediment trap upstream of gas controls.
• Use two pipe wrenches when making connection to gas
valve to keep it from turning.
•
• Tighten all joints securely.
• Propane gas connections should only be made by
licensed propane installer.
• Two-stage regulation should be used by propane
installer.
• Propane gas piping should be checked out by propane
installer.
