II, III, or IV gas appliances. Type B Vent shall not be used to vent flue products

from incinerators, combination gas/oil appliances, oil-fired, or wood-burning

appliances. If there is a question about the use of Type B Vents, contact the

appliance manufacturer or Simpson Dura-Vent's Engineering Department for

further information.

PLANNING

1. Appliances. Carefully review the appliance manufacturer's installation

instructions for positioning the unit, any special venting or connector require-

ments, and verify that it is a Category I appliance or an appliance that requires

the use of Type B gas vent.

2. Placement. The place-

ment of the vent and fittings must

be in accordance with Local

Codes, as well as accepted vent-

ing practices. If more than one

appliance is to be connected to

one venting system, the common

vent must be correctly sized. It is

a good idea to make a sketch of the

proposed installation, labelling

the components you will need.

Adjustable Pipe Lengths are

available to make up odd lengths.

Minimize the number of turns and

lateral runs, as the National Fuel

Gas Code places limitations on

these. A 45° turn is preferable to

a 90° turn. The appliance refer-

ence material should be consulted

at this time, as well as any Local

Authority having jurisdiction. In

most localities, building permits

are required for any new appli-

ances, or modifications to exist-

ing venting systems.
