PART 7: VENTING, COMBUSTION AIR & CONDENSATE REMOVAL (CONTINUED)

40 or 80 pipe. FOAM CORE PIPING IS NOT APPROVED.

2.Remove all burrs and debris from joints and fittings.

3.All joints must be properly cleaned, primed, and cemented. Use only cement and primer approved for use with the pipe material. Cement must conform to ASTM D2564 for PVC or CPVC pipe and ASTM D2235 for ABS pipe.

WARNING

All joints of positive pressure vent systems must be sealed completely to prevent leakage of flue products into the living space.

4.Horizontal lengths of exhaust vent must slope back towards the boiler not less than ¼" per foot to allow condensate to drain from the vent pipe. If the exhaust pipe must be piped around an obstacle that results in the creation of a low point, condensate will collect in this low point and form a blockage. This condensate must be drained away using a field-installed condensate drain assembly as shown.

5.All piping must be fully supported. Use pipe hangers at a minimum of 4 foot intervals to prevent sagging of the pipe where condensate may form.

6.Do not use the boiler to support any piping.

7.A screened straight coupling is provided with the boiler for use as an outside exhaust termination.

8.A screened inlet air tee is provided with the boiler to be used as an outside intake termination.

9.The following information on Table 7.7 are optional intake air/exhaust vent terminations available from Heat Transfer Products, Inc.

G. HEATER REMOVAL FROM A COMMON

VENT SYSTEM

At the time of removal of an existing heater, the following steps shall be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to com- mon venting system are not operating.

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 defi- ciencies that could cause an unsafe condition.

3.If practical, close all building doors, windows and all doors between the space in which the appliance remains connected to the common venting system located 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 with 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
