Installing the water heater: Indoor Water Heater Caulk Rising moisture will collect under eaves. If soffit vent is too close, block off and install new vent at another location. Inside Corner Caulk 6' (1.8 m) Caulk Zone 6' (1.8 m) 6' (1.8 m) Caulk zone or to edge of window etc.,starting within 6' (1.8 m). Caulk RTV silicone caulk 4' (1.2 m) 1 ft. sq. (30 x 30 cm) sheet metal plate on brick or masonry surface, recommended. 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 WARNING: For multiple unit installation, a minimum distance between vent terminations must be maintained to prevent recirculation of vent gases. Maintain a center-­to-­center distance between vent terminations of 19 inches (48 cm) for two unit installation. Maintain a center-­to-­center distance between vent terminations of 21 inches (53 cm) for three or more unit installation. Additional Considerations D o NOT install vent terminal under any patio or deck. T o help prevent moisture from freezing on walls and under eaves, do not locate vent terminal on the side of a buildi ng with prevailing winter winds. To help prevent water lines from freezing, do not locate vent terminal on the side of a building with prevailing winter winds. D o NOT terminate vent directly on brick or masonary surfaces. A rust resistant sheet metal backing plate (1x1 foot) (30x30 cm) is recommended behind vent. See figure on left. D o Not locate vent terminal too close to shrubbery, as flue gases may damage them. C aulk all cracks, seams and joints within six (6) feet (1.8 m) of vent terminal. C aulk around wall face plate for weather tight seal. A ll painted surfaces should be primed to lessen the chance of physical damage. Painted surfaces will require maintenance. D o NOT extend exposed vent pipe of indoor water heaters outside of building. Guard vent against accidental contact with people and pets. 12 AP15317 (10_09) DV Gas Manual 10 30 09.indd 12 11/9/2009 3:10:25 PM

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 building with
prevailing winter winds.
To help prevent water lines from freezing, do not locate vent
terminal on the side of a building with prevailing winter winds.
Do NOT terminate vent directly on brick or masonary surfaces. A
rust resistant sheet metal backing plate (1x1 foot) (30x30 cm) is
recommended behind vent. See figure on left.
Do Not locate vent terminal too close to shrubbery, as flue gases
may damage them.
Caulk all cracks, seams and joints within six (6) feet (1.8 m) of vent
terminal.
Caulk around wall face plate for weather tight seal.
All painted surfaces should be primed to lessen the chance of
