HORIZONTALLY VENTED UNIT HEATERS

 (CATEGORY III)

Horizontal venting arrangements are designed to be 
used with single wall vent pipe. Horizontal venting 
arrangements must terminate external to the building 
using either single wall or double wall (Type B) vent. If 
single wall vent pipe is used, it must be constructed of 
26 gauge galvanized steel or a material of equivalent 
durability and corrosion resistance for the vent system. 
For installations in Canada, use corrosion resistant and 
gas-tight, listed vent pipe conforming with local building 
codes, or in the absence of local building codes, with 
current CAN/CGA-B149.1, Installation Codes for Natural 
Gas Burning Appliances and Equipment or CAN/CGA-
B149.2, Installation Codes for Propane Gas Burning 
Appliances and Equipment. See Figures 7, 8A and 9A for 
special installation requirements regarding these venting 
conditions.

 Do not use Type B (double wall) 

vent internally within the building on horizontally 
vented power vented units!

If double wall venting is used, components which are UL 
Listed and approved for Category III positive pressure 
venting systems MUST be used.

A Breidert Type L, Fields Starkap, or equivalent vent cap 
must be supplied by the customer for each power vented 
unit. The vent pipe diameter MUST be as specified in 
Table 1 (“D” Dia. Flue Opening). All unit sizes are factory 
equipped with the required fl ue size collar; attach in place 
(if not mounted to outlet); refer to included vent collar 
instruction sheet for additional requirements.

Vent Systems - Termination Clearance Requirements

 

Minimum Clearances for

 

Structure  

Termination Locations

   

4 feet below

  Door, window or any gravity air inlet  4 feet horizontally

   

1 foot above

  Forced air inlet within 10 ft. 

3 feet above

  Adjoining building or parapet 

6 feet

  Adjacent public walkways 

7 feet above grade

The venting system for these appliances shall terminate 
at least 4 feet (1.2m) below, 4 feet (1.2m) horizontal from, 
or 1 foot (0.3m) above any door, window, or gravity vent 
air inlet into the building.

The vent terminal must be at least 12 inches (305mm) 
from the exterior of the wall that it passes through to 
prevent degradation of the building material by flue 
gases.

The vent terminal must be at least 3 feet (1m) above 
grade, or in snow areas, at least 3 feet above the snow 
line to prevent blockage by snow.

Through the wall vent for these appliances shall NOT 
terminate over public walkways, or over an area where 
the condensate or vapor could create a nuisance or 
hazard or could be detrimental to the operation of 
regulators, relief valves, or other equipment.

The vent pipe equivalent length must not exceed 50 feet 
(15.2m). Equivalent length is the total length of straight 
sections PLUS 15 feet (4.6m) for each 90 elbow and 
8 feet (2.44m) for each 45 elbow.

Maintain 6 inches (152mm) between the vent pipe and 
combustible materials.

The vent terminal must be installed with a minimum 
horizontal clearance of 4 feet (1.2m) from electric meters, 
gas meters, regulators, and relief equipment.

Seal all vent pipe joints and seams to prevent leakage. 
Use General Electric RTV-108, Dow-Corning RTV-732 
silicone sealant or equivalent; or 3M #425 aluminum 
foil tape (or equivalent). The vent air system must be 
installed to prevent collection of condensate. Pitch 
horizontal pipes downward 1/4 inch per foot (21mm per 
meter) toward the outlet for condensate drainage.

Horizontal portions of the venting systems shall be 
supported at maximum intervals of 4 feet (1.2m) to 
prevent sagging (in Canada, support at 3 feet (1m) 
maximum intervals).

Insulate single wall vent pipe exposed to cold air or 
running through unheated areas.

Each unit must have an individual vent pipe and vent 
terminal!

 Each unit MUST NOT be connected to other 

vent systems or to a chimney.
