COMBUSTION & VENTILATION AIR REQUIREMENTS

2.Inspect the venting system for proper size and horizontal pitch, as required by the National Fuel Gas Code, ANSI Z223.1 or the Natural Gas and Propane Installation Code, CSA B149.1-05 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 shall operate at maxi- mum speed. Do not operate a summer exhaust fan.

6.Follow the lighting instructions. Place the appliance being inspected in operation. Adjust thermostat so appliance shall operate continuously.

7.Test for spillage from draft hood 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 National Gas and Propane Installation Code CSA B149.1-05.

9.After it has been determined that each appliance connected to the venting system properly vents when tested as out- lined above, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance to their previ- ous conditions of use.

If resizing is required on any portion of the venting system, use the appropriate table in Appendix G in the latest edition of the National Fuel Gas Code ANSI Z223.1 and/or CSA B149.1-05 Installation Codes.

THERMOSTATLOCATION

The thermostat should be placed approximately five feet from the floor on a vibration-free, inside wall in an area having good air circulation. Do not install the thermostat where it may be influ- enced by any of the following:

•Drafts, or dead spots behind doors, in corners, or under cabinets.

•Hot or cold air from registers.

•Radiant heat from the sun.

•Light fixtures or other appliances.

•Radiant heat from a fireplace.

•Concealed hot or cold water pipes, or chimneys.

•Unconditioned areas behind the thermostat, such as an outside wall.

Consult the instructions packaged with the thermostat for

mounting instructions and further precautions.

COMBUSTION & VENTILATION AIR REQUIREMENTS

WARNING

TO AVOID PROPERTY DAMAGE, PERSONAL INJURY OR DEATH, SUFFICIENT FRESH AIR FOR PROPER COMBUSTION AND VENTILATION OF FLUE GASES MUST BE SUPPLIED. MOST HOMES REQUIRE OUTSIDE AIR BE SUPPLIED INTO THE FURNACE AREA.

Improved construction and additional insulation in buildings have reduced heat loss by reducing air infiltration and escape around doors and windows. These changes have helped in reducing heating/cooling costs but have created a problem supplying com- bustion and ventilation air for gas fired and other fuel burning appliances. Appliances that pull air out of the house (clothes dryers, exhaust fans, fireplaces, etc.) increase the problem by starving appliances for air.

House depressurization can cause back drafting or improper com- bustion of gas-fired appliances, thereby exposing building occu- pants to gas combustion products that could include carbon mon- oxide.

If this furnace is to be installed in the same space with other gas appliances, such as a water heater, ensure there is an adequate supply of combustion and ventilation air for the other appliances. Refer to the latest edition of the National Fuel Gas Code NFPA 54/ANSI Z223.1 or CAN/CSA B149 Installation Codes or appli- cable provisions of the local building codes for determining the combustion air requirements for the appliances.

Most homes will require outside air be supplied to the furnace area by means of ventilation grilles or ducts connecting directly to the outdoors or spaces open to the outdoors such as attics or crawl spaces.

INSTALLATION POSITIONS

This furnace may be installed in an upright position or horizontal on either the left or right side panel. Do not install this furnace on its back. For upright upflow furnaces, return air ductwork may be attached to the side panel(s) and/or basepan. For horizontal upflow furnaces, return air ductwork must be attached to the basepan. For both upright or horizontal counterflow furnaces, return ductwork must be attached to the basepan (top end of the blower compartment). NOTE: Ductwork must never be attached to the back of the furnace. Contact your distributor for proper airflow requirements and number of required ductwork connec- tions. Refer to “Recommended Installation Positions” figure for appropriate installation positions, ductwork connections, and re- sulting airflow arrangements.
