Combustion air requirements | Bosch Appliances 2400E LP, 2400E NG

Installation instructions

pitch down towards termination ¼ inch for every foot of horizontal length.

Single pipe method:

Although it is permissible to draw combustion air from the inside, it is not the manufacturer’s recommended installation method. Always install a 3 inch elbow on the top of the combustion air inlet adaptor to prevent foreign objects from falling into the unit.

If a single pipe installation is utilized, follow guidelines below for providing adequate combustion air for the water heater as well as any other appliances that may consume air in the space. Always follow local codes if they are more stringent.

Warning: In areas where outside temperatures commonly fall below 36°F, a twin pipe venting system is required. Failure to do so may result in cold outside air being drawn across the heat exchanger causing it to freeze and burst. This failure is not covered under the manufacturer’s warranty.

Warning: When installed in an environment where corrosive chemicals or dirty air are present, the twin pipe system is required.

Twin pipe method:

The 2400 E is designed as a sealed combustion appliance. It is recommended that the combustion air be provided by a dedicated 3” or 4” pipe to the outside. The combustion air pipe may be aluminum flex, PVC or any other rigid or semi rigid sealed 3” or 4” pipe. The combustion air inlet, whether terminating vertically or horizontally, must be located in such a manner as to provide a minimum 3 foot clearance from the exhaust vent terminator. See Fig. 17 Letter I.

The maximum length of the combustion air inlet is 26 feet with one elbow. Subtract 2.5 feet for additional elbows. Maximum number of elbows permitted is 3.

The 2400 E water heater holds cold water in its copper heat exchanger and water valve when not in use. Because of this, any cold air that comes through the unit's vent pipe could freeze and damage these components. This Installation Manual specifies the minimum vertical vent pipe and the amount of combustion air required for this unit. When all requirements are followed, the unit will operate properly and safely. However, there may still be a risk of freezing due to negative draft if the other combustion appliances in the building are not supplied with sufficient combustion air. A wood stove or furnace can pull its combustion air from the heater's vent pipe, allowing the cold incoming air to freeze the cold water in the heat exchanger. Supplying more combustion air for all combustion appliances is the solution. A HVAC specialist should be consulted to design solutions for providing more combustion air. Observe the following guidelines:

Installations in structures that have been tightly constructed (air infiltration rate of 0.40 ACH or less) must be provided with combustion air per the National
