Yes you can vent a gas fired water heater out of the wall if it is either a power vent unit.

All water heater venting systems use a vent duct or pipe also called a chimney or flue to bring exhaust gases from the water heater to the outdoors. Direct venting or side wall vent chimney and flue systems are a method of venting the exhaust gases from a heating appliance directly out through the side wall of a building while eliminating the need for a vertical chimney of any sort. The atmospheric water heater is very common. This water heater is found in different homes.

The difference is that a power vent water heater pulls in combustion air from the space. A water heater using atmospheric venting or direct venting will allow the fumes to exhaust naturally by rising straight up through a vertical vent which is routed to the home s chimney or through an upward sloping vent which may be routed through the chimney or through a wall to the home s exterior. The purpose of venting a gas or oil fired water heater is to completely remove all products of combustion and to vent gasses to the outside air without condensation in the vent or spillage at the draft hood except in cases of downdraft or poor stack conditions. They do make two models of power vent units one is called a direct vent power vent as bob harper pointed out it draws its combustion air from outside unlike a standard power vent unit which burns its combustion air from the dwelling.
