Additional Considerations

  

Do Not install vent terminal under any patio or deck.

  To help prevent moisture from freezing on walls and under  

eaves, do not locate vent terminal on the side of a build ing 

with prevailing winter winds.

  When terminating the vent pipe through brick or masonry 

surfaces, a rust-resistant sheet metal backing plate  

behind the vent termination is recommended. 

(See illustration.)

  Do Not locate vent terminal too close to shrubbery, as flue 

gasses may damage them.

  Caulk all cracks, seams and joints within six (6) feet of vent 

terminal.

  All painted surfaces should be primed to lessen the chance of 

physical damage. Painted surfaces will require maintenance.

  Insulate vent pipe exposed to cold conditions (attics, crawl 

spaces, etc.) with inflammable material to help prevent 

moisture from accumulating in vent pipe.

  

Do Not extend exposed vent pipe outside of building.

If soffit vent is too 

close, block off and 

install new vent at 

another location

WARNING

Moisture in the flue gas will condense as it 

leaves the vent terminal. In cold weather this condensate can 

freeze on the exterior wall, under the eaves and on 

surrounding objects. Some discoloration to the exterior of 

the building is to be expected. However, improper location 

or installation can result in severe damage to the structure 

or exterior finish of the building

Horizontal Vent Terminal Location

The location of the vent terminal depends on the following 

minimum clearances and considerations (see illustration):

  Vent Terminal must be at least twelve (12) inches above 

grade level and above normal  

snow levels.

  Vent Terminal must be at least four (4) feet below, or four 

(4) feet horizontally from any door, operable window, soffit, 

under eave vent or gravity air inlet to the building or other 

appliances, or from gas or electric meters. Do not locate 

vent above walkways, doors,  windows, air inlets, gas or 

electric meters or other equipment.

  Vent Terminal must be at least three (3) feet above any 

forced air inlet located within ten (10) feet. Any fresh or 

make-up air inlet such as for a dryer or furnace area is 

considered to be a forced air inlet.

  Vent Terminal must be at least eighteen (18) inches from an 

inside corner formed by two exterior walls.

2 ft. sq. sheet metal plate on brick or
