SAFETY SECTION
The following safety practices and precautions must be followed during the installation, servicing, and opera- tion of this furnace.
1.Use only with the type of gas approved for this fur- nace. Refer to the furnace rating plate.
2.Install this furnace only in a location and position as specified in “Location and Clearances” (page 4), of these instructions.
3.Provide adequate combustion and ventilation air to the furnace space as specified in “Air for Combus- tion and Ventilation” (pages
4.Combustion products must be discharged outdoors. Connect this furnace to an approved vent system only, as specified in the “Venting” section (pages 13- 15), of these instructions.
5.Never test for gas leaks with an open flame. Use a commercially available soap solution made specifi- cally for the detection of leaks to check all connec- tions, as specified in “Gas Piping” (page 618), of these instructions.
6.Always install the furnace to operate within the furnace’s intended
7.When a furnace is installed so that supply ducts carry air circulated by the furnace to areas outside the space containing the furnace, the return air shall also be handled by a duct(s) sealed to the fur- nace casing and terminating outside the space con- taining the furnace.
8.A
9.The furnace may be used for temporary heating of buildings or structures under construction only when the following conditions have been met:
a.The furnace venting system must be complete and installed per manufacturer’s instructions.
b.The furnace is controlled only by a room thermo- stat (no field jumpers).
c.The furnace return air duct must be complete and sealed to the furnace and clean air filters are in place.
d.The furnace input rate and temperature rise must be verified to be within nameplate mark- ing.
e.100% of the furnace combustion air requirement must come from outside the structure.
▲! 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 CAN/CGA B149 Installation Codes 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 deficiencies which could cause an unsafe condition.
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 be- ing inspected into operation. Adjust the thermostat so appliance is operating continuously.
7.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 Z221.1/NFPA 54 and/or CAN/CGA B149 Installation Codes.
8.After it has been determined that each appliance connected to the venting system properly vents where tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other
f.The furnace return air temperature range is be- tween 55 and 80 degrees Fahrenheit.
g.Clean the furnace, duct work, and components upon substantial completion of the construction process, and verify furnace operating conditions including ignition, input rate, temperature rise and venting, according to the manufacturer’s in-
structions.
10.This product must be gas piped by a Licensed Plumber or Gas Fitter in the Commonwealth of Massachusetts.
