EX08DT and EX11DT Installation and Operation Manual
WARNING
When an existing Category I 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 not 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 the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 and/or
Natural Gas and Propane Installation Code,
CSA B149.1.
9. After it 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.
Do not block the warm air discharge. Do not
allow anyone to sleep directly in front of the
furnace.
Due to high temperatures, the furnace should
be located out of traffic and away from furniture
and draperies.
Children and adults should be alerted to the
hazards of high surface temperature and
should stay away to avoid burns or clothing
ignition.
Young children should be carefully supervised
when they are in the same room as the
furnace.
Clothing or other flammable material should
not be placed on or near the furnace.
Any safety screen or guard removed for
servicing must be replaced prior to operating
the furnace.
Do not insert items into the louvers.
Do not spray aerosols near the furnace while it
is operating. Most aerosols contain butane gas
which is flammable.
Do not unplug the furnace while it is operating
or while the fans are on.
Do not use bare hands to touch the front
louvers due to high temperatures which may
cause burns.
Wear hand protection when touching the side
back covers, front louver, and rear intake for
the convection fan.
Prevent dust from accumulating on the power
cord, side covers, and parts behind the
furnace.
Do not sit on the furnace.
Do not place containers of liquid on top of the
furnace. Water spillage can cause extensive
damage to the furnace and may result in
electric shock.
