turer is not permitted; the vent cap must be the type approved for use with this heater. A different style vent cap could cause nuisance prob- lems or unsafe conditions.

See the illustrations in Figures 6 and 7 for requirements of both verti- cal and horizontal vent termination. The vent terminal section may be

either single-wall or double-wall (Type B) vent pipe. If double-wall pipe is used in the vent terminal with a single-wall vent run, follow the instructions in No. 4, Vent System Joints, to attach the vent cap and to connect the double-wall pipe to the single-wall vent pipe run.

Figure 7 - Horizontal Vent Terminals

Horizontal Vent Terminal Clearances:

The location of the termination of the hori- zontal vent system must be in accordance with National Fuel Gas Code Z223.1. Required minimum clearances are listed on the right.

Products of combustion can cause discolora- tion of some building finishes and deteriora- tion of masonry materials. Applying a clear silicone sealant that is normally used to pro- tect concrete driveways can protect masonry materials. If discoloration is an esthetic prob- lem, relocate the vent or install a vertical vent.
