When an existing Category 1 heater is removed or replaced,
the original venting system may no longer be sized to
properly vent the attached appliances. Instructions shall
also indicate effects of an improperly sized venting system
(formation of condensate, leakage, spillage, etc.) and shall
specify the following test procedure:
WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each
appliance connected to the venting system being
placed into operation could result in carbon monoxide
poisoning or death.
The following steps shall be followed for each
appliance connected to the venting system being
placed into operation, while all other appliances
connected to the venting system are not in operation:
1.
Seal any unused openings in the venting system.
2.
Inspect the venting system for proper size and
horizontal pitch, as required in the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 or the Natural
Gas and Propane Installation Code, CSA B149.1
and these instructions. Determine that there is no
blockage or restriction, leakage, corrosion and
other deficiencies which could cause an unsafe
condition.
3. As far as practical, close all building doors and
windows and all doors between the space in which
the appliance(s) connected to the venting system
are located and other spaces of the building.
4.
Close fireplace dampers.
5. Turn on clothes dryers and any appliance not
connected to the venting system. Turn on any
exhaust fans, such as range hoods and bathroom
exhausts, so they are operating at maximum
speed. Do operate a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance
being inspected into operation. Adjust the
thermostat so appliance is operating continuously.
7.
Test for spillage from draft hood equipped
appliances at the draft hood relief opening after 5
minutes of main burner operation. Use the flame
of a match or candle.
8.
If improper venting is observed during any of the
above tests, the venting system must be corrected
in accordance with National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and/or Natural Gas and Propane
Installation Code, CSA B149.1.
9. After is has been determined that each appliance
connected
to the venting system properly vents
when tested as outlined above, return doors,
windows, exhaust fans, fireplace dampers and
any other gas-fired burning appliance to their
previous conditions of use.
