NeoTherm LC Boilers and Water Heaters
placed in operation, while the other appliances
remaining connected to the 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 restriction, leakage, corrosion or
other deficiencies which could cause an unsafe
condition.
3. As much as possible, close all building doors
and windows. Also close 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 any clothes dryers or other appliances 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 summer
exhaust fan. Close any fireplace dampers.
4. Place in operation the appliance being
inspected. Follow the lighting instructions. Adjust
the thermostat so the appliance will operate
continuously.
5. Test for spillage at the draft hood relief opening
after five minutes of main burner operation. Use
the flame of 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 the doors, windows, exhaust fans,
fireplace dampers and any other gas burning
appliances to their previous conditions of use.
7. Any improper operation of the common
venting system should be corrected so that
the installation conforms to the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 and/or CSA
B149.1, Installation Codes. 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 and guidelines in the
National Fuel Gas Code, ANSI Z223.1 NFPA 54
and/or CSA B149.1, Installation Codes.
3.F
Outdoor Installation
This unit may only be installed outdoors in
applications where the outdoor temperature doesn't
drop below freezing. For proper operation in outdoor
installations, the boiler must be equipped with the
inlet air and exhaust terminal kits listed in Table 6 on
page 8. The bottom panel cover plate must be
removed. Additional instructions are supplied with
the terminal kits.
3.G Condensate Drain Trap
A condensate drain trap is included with the unit and
is designed to drain the boiler of condensate. The
vent condensate should be drained through a drain
tee located in the vent line. This will help prevent
excessive condensate from entering the boiler
condensate trap and preventing the boiler from
operating.
Connect a 3/4" PVC pipe between the drain
connection and a floor drain (or condensate pump if
a floor drain is not accessible).
The condensate drain must be installed to
prevent the accumulation of condensate. When
a condensate pump is not used, the tubing must
continuously slope downward toward the drain with
no spiraling.
Consult local codes for the disposal method.
Condensate is mildly acidic (pH=5), and
may harm some floor drains and/or pipes,
particularly those that are metal. Ensure
that the drain, drainpipe, and anything that
will come in contact with the condensate
can withstand the acidity, or neutralize
the condensate before disposal. Damage
caused by failure to install a neutralizer kit
or to adequately treat condensate will not
be the manufacturers responsibility.
