VICTORY II VHS Models

APPENDIX A

Vent System Location and Condensation

Drain Requirements

1.The venting system shall terminate at least 3 feet above any forced air inlet located within 10 feet.

2.The venting system shall terminate at least 4 feet below, 4 feet horizontally from, or 1 foot above any door, window or gravity air inlet into any building. The bottom of the vent terminal shall be at least 12 inches above grade or the normal snow level, whichever is greater.

3.Through the wall vents for Category II and IV appli- ances shall not terminate over public walkways or over areas where condensate or vapor could create a nuisance or hazard or could be detrimental to the operation of regulators, relief valves or other equip- ment. Minimum clearance of 4' horizontally from, and in no case above or below, unless a 4' horizon- tal distance is maintained, from electric meters, gas meters, regulators and relief equipment. Where local experience indicates that condensate may be a problem with Category I and III appliances, this provision shall also apply.

4.Provision shall be made to collect and dispose of condensate from venting systems serving Category I, II, III and IV appliances.

Caution

Flue gases exiting from the vent terminal will con- dense. Building materials in the area of the vent termi- nal should be protected from discoloration and degra- dation.

APPENDIX B

Removal of Existing Boiler From

Common Vent System

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

b.Visually inspect the venting system for proper size and horizontal pitch and determine there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.

c.Insofar as is practical, close all building doors and windows and all doors between the space in which the appliances remaining connected to the com- mon venting system are located and other spaces of the building. Turn on clothes dryer and any appli- ance not connected to the common venting sys- tem. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximium speed. DO NOT operate a summer exhaust fan. Close fireplace dampers.

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

e.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 ciga- rette, cigar or pipe.

f.After it has been determined that each appliance remaining connected to the common venting sys- tem properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance to their previous conditions of use.

g.Any improper operation of the common venting system should be corrected so the installation con- forms with the National Fuel Gas Code, ANSI Z223.1-latest edition. When resizing any portion of the common venting system, the common venting system should be resized to approach the mini- mum size as determined using the appropriate tables in Appendix G in the National Fuel Gas Code, ANSI Z223.1-latest edition.
