Use and Care Manual

WHL-015 REV. 9.4.14

Failure to follow all instructions can result in flue gas spillage and carbon

monoxide emissions, causing severe personal injury or death.

When removing an existing appliance, the following steps must be

followed.

1. Seal any unused openings in the common venting system.

2. Visually inspect the venting system for proper size and horizontal pitch

to determine if there is blockage, leakage, corrosion or other deficiencies

that could cause an unsafe condition.

3. If practical, close all building doors, windows and all doors between the

common venting system and other spaces in the building. Turn on clothes

dryers and any appliances not connected to the common venting system.

Turn on any exhaust fans, such as range hoods and bathroom exhausts,

at maximum speed. Do not operate a summer exhaust fan. Close all

fireplace dampers.

4. Place in operation the appliance being inspected. Follow the lighting

instructions. Adjust the thermostat so the appliance will operate

continuously.

5. Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle or

smoke from a cigarette.

6. After it has been determined that each appliance remaining connected to common venting system properly vents when tested as

outlined, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance to their previous condition of use.

7. Any improper operation of the common venting system should be corrected so the installation conforms to the National Fuel Gas

Code, ANSI Z223.1. When resizing any portion of the common venting system, the common venting system should be resized to

approach the minimum size as determined using the appropriate tables in Appendix G in the National Fuel Gas Code, ANSI Z 223.1.
