Placing The Boiler - Dunkirk 90-50 Installation, Operation & Maintenance Manual

Condensate drain requirements
Condensate drain line to be pitched down to floor drain at a mini-
mum of ¼" per foot. An external condensate pump (not furnished)
may be used if floor drain is not available. The condensate pump
must be designed for flue gas condensate application.
1. condensate trap is built into the boiler, an
external trap is not required and should not
be used.
2. Wood frame or blocks may be used to raise
the boiler to maintain drain pitch or to be
above external condensate pump reservoir.
3. There is a 115 Volt Ac receptacle provided
on the service switch junction box which is
located at the boiler right side, to provide
power for an external condensate pump (if
needed).
foundation requirements
Boiler must be placed on level surface. Boiler is NOT to be installed
on carpeting.
If boiler is not level condensate drain lines
will not function properly. Adjustable feet are
located on the boiler to make up for minor
surface irregularities or tilt.
Wood frame or blocks may be used to raise
boiler to maintain drain pitch or to be above
external condensate pump reservoir.
removal of existing boiler from Common Vent system
When an existing boiler is removed from a common venting system,
the common venting system is likely to be too large for proper vent-
ing of the appliances remaining connected to it. At the time of re-
The boiler should be placed to provide the most direct connections
to the combustion air, vent and system piping as possible.
Place crated boiler as close to selected location as possible and
uncrate boiler. The uncrated boiler may be moved into position with
an appliance dolly or 2-wheel hand truck. The dolly or hand truck
should be inserted under the left hand side of the boiler. It is possible
to slide the boiler for a short distance on a smooth floor or surface.

moval 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.
Seal any unused openings in the common venting system.
1.
Visually inspect the venting system for proper size and hori-
2.
zontal pitch and determine there is no blockage, or restrictions,
leakage, corrosion and other deficiencies which could cause an
unsafe condition.
In-so-far as is practical, close all building doors and windows
3.
and all doors between the space in which the appliances remain-
ing connected to the common venting system are located and
other spaces of the building. Turn on clothes dryer and any ap-
pliance not connected to the common venting system. Turn on
any exhaust fans, such as range hoods and bathroom exhaust, so
they will operate at maximum speed. Do not operate a summer
exhaust fan. Close fire dampers.
Place in operation the appliance being inspected. Follow the
4.
lighting instructions. Adjust thermostat so appliances will oper-
ate continuously.
Test for spillage at the draft hood relief opening after 5 minutes
5.
of main burner operation. Use the flame of a match or candle,
or the smoke from a cigarette, cigar or pipe.
After it has been determined that each appliance remaining
6.
connected to the common venting system properly vents when
tested as outlined above, return doors, windows, exhaust fans,
fire place dampers, and any other gas-burning appliance to their
previous condition of use.
Any improper operation of the common venting system should
7.
be corrected so the installation conforms with the National Fuel
Code, NFPA-54/ANSI -Z223.1 and/or the Natural Gas and
Propane Installation Code, CAN/CSA B149.1.. When resizing
any portion of the common venting system, the common vent-
ing system should be resized to approach the minimum size as
determined using the appropriate tables in Chapter 13 of the
National Fuel Gas Code, NFPA-54/ANSI- Z223.1 and/or the
Natural Gas and Propane Installation Code, CAN/CSA B149.1.
Refer to manual section "locating the
boiler" (page 9 of this manual), for required
clearances for servicing and maintenance.
