A.Venting Components

In order to comply with applicable codes and product warranties, use only following venting components:

•Hearth & Home Technologies (HHT)

•Simpson Dura-Vent (SDV)

•Selkirk

•AmeriVent

•Security Secure Vent

DO NOT USE FIELD-FABRICATED VENTING

COMPONENTS. Refer to the venting manufacturer’s instructions.

This product is approved to be vented either horizontally, through the side wall or vertically through the roof. You may vent through a Class A or masonry chimney if an approved adapter is used.

This appliance is a direct vent heater. All combustion air must come directly from the outside of the building. The vent pipe for this unit consists of an inner and an outer pipe. The inner pipe carries the appliance exhaust out of the system, and the outer pipe brings fresh combustion air into the appliance.

•A round support box/wall thimble or heat shield is required when the venting passes through a combus- tible wall.

•A support box or ceiling firestop is required when the venting passes through a ceiling.

•Roof flashing and a storm collar are required when vent- ing passes through the roof.

•Follow instructions provided with the venting for instal- lation of these items.

B. Use of Elbows

CAUTION

ALL vent configuration specifications MUST be followed.

•This product is tested and listed to these specifications.

•Appliance performance will suffer if specifications are not followed.

Diagonal runs have both vertical and horizontal vent aspects when calculating the effects. Use the rise for the vertical aspect and the run for the horizontal aspect. (See Figure

5.1.)

Two 45° elbows may be used in place of one 90° elbow. On 45° runs, one foot of diagonal is equal to 8-1/2 in. (216mm) horizontal run and 8-1/2 in. (216mm) vertical run. A length of straight pipe is allowed between two elbows. (See Figure

5.1.)
