H. INSTALLATION

1. Vent Adaptor.

Attach vent adaptor at draft inducer collar.  See figure 18 on page 18.  Use Kit #

56111101 for ODV 50-125 and Kit # 56111102 for ODV 150-200, or equivalent.

WARNING:

 Make sure that all vent pipe and connectors are secured because

unsecured vent pipe connections may loosen. This can allow combustion products to collect
in the structure, resulting in injury or death.

2. Vent Connector.

Install vent connectors without any dips or sags. Slope them upward from boiler at

least 1/4" per foot. To prevent sagging, at each joint support vent connectors and horizontal
portions using hangers, straps or equivalent. Seal all connections where vent connectors
enter chimney. See Figure 11 on page 13.

3. Vertical Vent

Install vent materials following their listing terms, manufacturer’s instructions, these

instructions and local codes. A gas vent passing through a roof must extend through roof
flashing, jack or thimble. It must terminate above the roof surface.(Ref. Figure 14 & 15)

I. EXISTING VENT CONSIDERATIONS

MASONRY CHIMNEYS PREVIOUSLY USED FOR VENTING EQUIPMENT SHOULD BE
SUITABLY PER NFGC STANDARD. Also provide an accessible clean out per the latest
revision of the NFGC, ANSI Z223.1, AND NFPA 54.1. When installed in Canada: The latest
revision of the CAN/CSA - B149 Natural Gas and Propane Installation Code.

1. INSPECTION OF VENTS

A. Make sure existing vent or chimney is the proper size and construction for

appliances that will use it. The best way to do this is to size as if it were a new installation.
Compare the existing vent to your calculations and make necessary corrections.
