Installer’s Guide

SAFETY SECTION

The following safety practices and precautions must be followed during the installation, servicing, and operation 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 8-9), of these instruc- tions.

4.Combustion products must be discharged outdoors. Connect this furnace to an approved vent system only, as specified in the “Venting” section (starting on page 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” (pages 31-33), of these instructions.

6.Always install the furnace to operate within the furnace’s intended temperature-rise range with a duct system which has an external static pressure within the allowable range, as specified on the unit rating plate. Airflow with temperature rise for cfm versus static is shown in the Service Facts accompa- nying this furnace.

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 gas-fired furnace for installation in a residential garage must be installed as specified in “Location and Clearances” section (page 4), of these instruc- tions.

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 manufacturers instructions.

b.The furnace is controlled only by a room ther- mostat (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 require- ment must come from outside the structure.

f.The furnace return air temperature range is between 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 instructions.

10.This product must be gas piped by a Licensed Plumber or Gas Fitter in the Commonwealth of Massachusetts.

▲! WARNING

CARBON MONOXIDE POISONING HAZARD

Failure to follow the steps outlined below for each ap- pliance connected to the venting system being placed into operation could result in carbon monoxide poi- soning or death.

The following steps shall be followed for each appli- ance 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 con- nected 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 appli- ance being 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 B149.1 In- stallation Codes.

8.After it has been determined that each appliance connected to the venting system properly vents where tested as outlined above, return doors, win- dows, exhaust fans, fireplace dampers and any other gas-fired burning appliance to their previous conditions of use.
